Don't choose too big pots for changing pots, or the roots will rot easily, okay?

Don't choose too big pots for changing pots, or the roots will rot easily. Do you know 1? Do not water 3-5 days before changing pots. It's best to dry the pot soil a little, so as not to hurt the roots.

2. After potted flowers, one third of the original soil should be reserved to avoid damaging the root system.

3. Pruning: When changing pots, prune the rotten roots and old roots on the root system, but be careful not to hurt the main root system.

4, the new pot should be the right size, do not use a big pot for small flowers.

5. When to change the pot, it is best to change the pot when the temperature is about 20 degrees. Generally, the pot soil should be changed once according to 1-2 required for the growth of potted plants, so as to enrich the soil and increase the growth space of plants.

The time and year of changing potted plants must not be ignored (1).

The time of changing pots varies with different tree species. Generally, it is carried out in spring and autumn when trees grow slowly. Generally, cold-tolerant trees such as elm can change pots earlier, while warm-loving trees such as Fujian tea, Lagerstroemia indica and boxwood should change pots later, which is close to early summer.

(2) Year of changing pots

The cycle of changing pots should depend on the size, species and growth of trees in pile landscape. Generally, the big basin is replaced once every 3-5 years, the middle basin is replaced once every 2-3 years, and the small basin is replaced once every 1-2 years. The fast-growing stumps should be replaced every 1-2 years, and the slow-growing stumps should be replaced every 3-5 years. The lush heap landscape can prolong the pot changing period. If the growth rate decreases, the pot soil is dry and hard, and the permeability and drainage are poor, the time for changing pots can be shortened.

(3) replace the old soil

Every time a basin is changed, the old soil of 1/3- 1/2 should be removed and replaced with new soil.

(4) root system treatment

Potted trees cultivated for one or two years often have old roots at the bottom of the basin, which affects the absorption of water and nutrients. Therefore, it is necessary to change pots, cut off old roots and rotten roots, and promote the germination of new roots. It is best to disinfect the roots with medical eye ointment or sulfanilamide ointment. The purpose of disinfecting the pruned roots with drugs is to prevent bacterial infection.

(5) basin bottom treatment

The drainage holes at the bottom of the basin should be covered with tiles or other thin sheets that can block soil to prevent soil erosion during watering. At the same time, the basin bottom can be paved with cinder or coarse sand to facilitate drainage.

(6) Cleaning and disinfection of bonsai.

Used bonsai pots must be cleaned before use, otherwise they are easy to be infected with germs.

(7) Soil moisture in the basin

Too wet or too dry soil is not conducive to changing pots. Too wet, easy to stick mud, not conducive to root pruning and old soil removal; Too dry, it is easy to damage the root system when changing pots. More bonsai knowledge to share with you. According to the situation, it is best to water the pot once before changing it, and then change the pot when the soil is wet and dry.

(8) Management after changing pots

After changing the basin, put it in a semi-cool and ventilated place and water it once with a fine watering can. After the new roots germinate, they can be slowly moved to the sun for maintenance.

Do you know which minefields in love are absolutely untouchable? When we are really in love, because two people have been stuck together, we will naturally project what we think is right on him/her. Because of personality reasons, each holds his own opinion and is likely to break up in discord. So, remember not to step on some minefields in love.

Disrespect for each other's parents

This is a matter of principle for many people. Imagine that if someone doesn't respect your parents, you can't stand it. Besides, treat ordinary people, not to mention your future partner. After all, two people will live together in the end, so I advise you not to step on this thunder. If you step on this mine, it will explode.

Take violent action

Whether in love or marriage, no one can endure being abused for a long time. Some people may say that I still love her despite the domestic violence, which is ridiculous. Does the way to love someone need to be expressed in such an extreme way? After all, this is a crime.

Disloyal

Cheating on the other half can be said to be very taboo. Whether a man or a woman is in love or having an affair with other members of the opposite sex, it will lead to endless quarrels with her lover and eventually lead to a breakup.

Mutual distrust

This can be said to be the fatal reason for 80% lovers to break up. Because I don't trust you, I'm on guard everywhere, peeking at my mobile phone, causing unnecessary misunderstanding. A very common thing will become very complicated and difficult to handle. The relationship between two people can't go back to the past.

Break up easily

When it comes to breaking up, the same lovers as usual will definitely not love you. In their eyes, your feelings are insignificant and dispensable. Although it may be a temporary evaporation, once the breakup is said, there will be irreparable cracks. Don't think that separation and integration in love is a test.

?

Accumulate dissatisfaction

There will inevitably be some small frictions in love. Don't say, when it broke out, just like a flood, you can't accept it. Don't keep your questions to yourself, say what you have. Honesty is always necessary for lovers. If you express your dissatisfaction, maybe the other person doesn't care at all.

Speak carelessly

Although I can't say anything in front. For example, it is harmless for one party to joke occasionally and call the other "fat pig"/"fool". But shouting "fat pig" all day doesn't hurt feelings, but it doesn't mean that the other party won't be sad. If you joke for a long time, you get serious.

Too much interference in each other's private lives.

Although we are in love, we are both independent individuals, so it is always good to leave more space for each other. There is a secret garden in everyone's heart, and everything should be natural.

Too haggle over every ounce

Always put your own ideas first, and it is a common problem for many lovers to give 123. In fact, if we can look at the problem from each other's point of view and understand each other better, it won't be like this.

Do you know that?/You know what? Do you know that?/You know what? When cooking, you must not miss this step, otherwise you are eating "toxins" and drowning this step.

Friends who often go to the kitchen will know that one step when we wash vegetables is "blanching".

However, many people often ignore this detail because they are quick when cooking, but they don't know that if this step is omitted, they are eating toxins when eating vegetables.

Mainly because "blanching" can remove pesticides from vegetables, but also remove harmful substances such as oxalic acid and nitrite, so it must not be omitted. Let's take a look at what kinds of vegetables must be cleaned by this step.

Longshui-long bean

This vegetable is familiar to everyone, that is, long beans. All vegetables with beans are vegetables with their own toxins, such as beans, fresh day lilies, kidney beans, lentils and so on.

Long beans contain carotenoids and phytohemagglutinin, which can cause vomiting, nausea and other poisoning phenomena if they are not ripe. The cleaning method of beans is to clean and remove the knots at both ends of beans, soak them in clear water for 5 minutes, and then boil them for 5 minutes.

Blanched water-broccoli

Broccoli, a vegetable that is not easy to clean, because its leaves are very miscellaneous. If you simply clean it, you will miss a lot of dead ends and don't wash it.

So when cleaning, you need to wash it first, and the second time you need to pat the blisters 15 minutes or so. Vegetables such as cauliflower and broccoli contain a lot of pesticide residues, and this step cannot be omitted.

Blanched water spinach

Spinach is a vegetable with more oxalic acid. In addition to spinach, purslane, amaranth, fresh bamboo shoots, bitter gourd and water bamboo are all high in oxalic acid content.

Because oxalic acid will combine with calcium in the intestine to form stones. Therefore, the oxalic acid content can be reduced by 30% ~ 80% after blanching. It is best to blanch this vegetable for 5~ 10 second, otherwise it will lose a lot of vitamins. It can be cooked after blanching or refrigerated after cold water.

Toona longshuiensis

Toona sinensis contains more nitrate and nitrite, which may form carcinogens in the body. However, scalding Toona sinensis 1 min with hot water can remove more than 2/3 of nitrite and nitrate. Therefore, Toona sinensis had better be blanched before cooking.

In fact, boiling water can not only "detoxify", but also make some foods more delicious.

Auricularia longshuiensis

It is easy to fry black fungus, but this problem can be avoided by blanching it with boiling water before frying. Auricularia auricula will absorb a lot of water when it is soaked, and blanching is beneficial to the discharge of water.

Therefore, there is basically no wok phenomenon when cooking. Need to be reminded that auricularia auricula is curly and has many "small grooves". After the scalded fungus is put into the drain net, it should be played several times.

Longshui tofu

Tofu is tender and crisp when cooked. Before cooking, blanching with water not only helps to remove the smell of beans, but also makes tofu firmer and less fragile when cooking.

Besides, you know what? Small drowning also has many skills. Let's talk about drowning skills in daily life.

Bleaching technique

1, enough water.

The amount of water for blanching vegetables should be the least. Insufficient water addition will prolong blanching time and affect the texture and taste of vegetables. In addition, the amount of vegetables added at one time should be appropriate. If there are many dishes to be cooked, it is recommended to cook them several times to avoid too much food and lowering the water temperature.

2. Don't cut too much.

If you cut vegetables into pieces, it is easy to lose their original flavor. If you blanch the water again, the vitamins and minerals in it will be greatly lost. So when cooking vegetables, try to keep the shape of vegetables intact.

3, the time should be short

If vegetables are left in water for too long, they will become boiled vegetables, which will affect the color, aroma and taste of dishes and aggravate the loss of vitamin C and minerals. Under normal circumstances, vegetables can be fished out if they change color slightly.

Step 4 add some salt

In the process of blanching vegetables, water-soluble nutrients, such as vitamin C and B vitamins, will be lost to the pot. However, if 1% salt is added to boiling water to make it close to normal saline solution, vegetables will be in an environment with relatively balanced intracellular and extracellular concentrations, and the diffusion rate of their soluble components into water will slow down.

But remember not to add too much salt, just half a spoonful of water and half a spoonful. In addition, two drops of oil can be added to boiling water, which can not only prevent the oxidase from destroying chlorophyll, but also keep the bright color of vegetables.

5, cold water cooling

Blanched vegetables, especially green leafy vegetables, have high temperature, and contact with oxygen in the air after being fished out, resulting in thermal oxidation and nutrient loss.

Therefore, the blanched vegetables should be cooled in time, and they can be put into cold boiled water, but they should be taken out immediately to avoid increasing the loss of nutrients.

Finally, many vegetables we usually buy contain pesticides. If we don't pay attention to this step, we will eat these toxins together when we eat vegetables. Do you know these vegetables that need blanching? Does everyone usually do this?

You know who shouldn't eat preserved eggs?

1. Minors: Preserved eggs are easy to produce heavy metals after pickling, and the metabolic function of minors is poor. Eating preserved eggs is prone to lead poisoning and has an impact on the development of teeth and bones. It may even affect the development of intelligence;

2. Hypertensive people and pregnant women: preserved eggs have high sodium content, which is more than 5 times that of fresh eggs, which will lead to thickening of blood vessel wall, water and sodium retention and elevated blood pressure. Preserved eggs contain high cholesterol, and salt is needed to make preserved egg lean porridge, as well as monosodium glutamate and sodium. Patients with hypertension, pregnant women who are more prone to pregnancy-induced hypertension and other people who need to control sodium intake should be careful to eat.

3. People with gastrointestinal diseases: Because preserved eggs are inevitably polluted and deteriorated during processing, it is easy for people to cause fever and accelerate gastrointestinal peristalsis and congestion after eating, so people with gastrointestinal diseases are not suitable for eating;

4. Patients with chronic liver disease: preserved eggs containing lead will increase the detoxification burden of the liver. Excessive consumption of preserved eggs by patients with liver disease may even lead to lead poisoning and inedible;

5. Old people should not eat preserved eggs: Preserved eggs are potentially carcinogenic, and some of the lead contained in them will replace calcium, reduce calcium intake and make the elderly lack calcium. During the processing of preserved eggs, vitamins A and B are lost in large quantities. For the elderly with poor digestive ability, it is best to try to eat some foods with high nutritional density (such as milk, fresh eggs, fish and poultry, fresh vegetables and fruits, etc.). ).

Precautions for eating preserved eggs

How did the color and unforgettable taste of preserved eggs come into being?

Preserved eggs are named after the pattern of pine flowers on the eggs, and they are needle-shaped crystals of amino acids. It takes soda to make preserved eggs. Under the action of alkali, protein is partially decomposed to produce amino acids, and some amino acids are decomposed to produce ammonia and hydrogen sulfide. This is the unique taste of preserved eggs, and people who love to eat will never forget it ~

Amino acids and amines react with a very small amount of glucose in eggs, which leads to browning and yellowing of egg whites. Metal elements in egg yolk react with amino acid decomposition products to form dark sulfide.
