What are the precautions for planting cucumber by direct seeding watering?

Cucumber is a widely planted vegetable in the north and south of China, and ensuring the annual supply of vegetables in China is an important role of people's basketball. Cucumber can be divided into longer South China cucumber, South China cucumber and greenhouse cucumber in North and South Europe. Different types of cucumbers have great differences in flavor and eating methods, but no matter which kind of cucumber, no matter from the production level, quality or consumers, it needs adequate water protection.

There is a proverb in agricultural production: water has nothing to gain, and fertilizer is less than fertilizer. This visible water plays an important role in the growth of crops. For most friends in the market, watering seems to be a matter without technical content, but there is a friend in the market who grows cucumbers with high yield and good harvest, and sometimes the problem is water. Next, starting with the watering of cucumber cultivation, we will talk about several misunderstandings that need to be avoided in the cultivation process.

Excess water supply

After sowing, germination rate and seedling are directly related to water content. If the water supply is insufficient, there will be a series of problems, such as slowness and seedling. So before sowing, this is a prerequisite. However, once the cucumber is sipped, it is different from sowing with water.

Water the original plants with cold water.

After cucumber seedlings are planted, the main task of management is to increase the temperature. Generally speaking, only the temperature in the shed is higher than 32 degrees Celsius, because only the temperature is more suitable, the cucumber roots can be mixed, and only the cucumber flows out from the new roots and absorbs water from the surrounding soil environment. Leaves on the ground will gradually restore growth, making slow-growing seedlings successful.

However, in early spring farming or greenhouse, groundwater is generally used for planting. At this time, the groundwater temperature is very low. If irrigated directly, the soil temperature will be significantly reduced and more heat will be absorbed by water heating. Therefore, it takes longer time to recover the soil temperature, thus delaying this process.

Drink water often.

It is necessary to dump the seedling water so that the soil can be sufficiently close to the roots of cucumber, so as to promote effective water and nutrition from the soil and promote its application. But a week or so, the seedlings need a week or so, and then keep moisture. However, in production, many vegetable farmers often feel that they should water more at this stage to speed up the emergence of seedlings, but this is a misunderstanding.

How to water it? 4 The misunderstanding of watering four times should be avoided, and high-yield and high-quality cultivation should be paid attention to. If the water temperature is too high, the sliding speed will be delayed, the soil will be barren and the oxygen supply will be insufficient. New root cucumber must have enough oxygen supply and natural air permeability. Root and propargyl glycoside, and if there is too much water at this stage, it will promote the growth of cells and make the surface of cucumber longer, but not thick enough.

The water is not timely.

Cucumber leaves have a strong ability to make nutrients, so the yield is faster and the temperature is suitable. Under the condition of light and nutrition, it can be harvested every day, even twice a day, but the effective way of cucumber leaves is high absorption. If the water supply is insufficient, it will not only affect the speed of yield formation, but also affect the taste of cucumber, and even lead to abnormal proportion.

In the case of good scenic spots, the temperature is high, the light is good, the ventilation can complement each other, and the soil humidity is more suitable and intuitive. Standard teacher. Hold the soil lightly and sew water marks on your fingers. Drip is suitable for light intensity.

Pay attention to the ground temperature.

Temperature is very important for the growth of cucumber. Generally, the terminal of cucumber should be about 22 degrees, and the greenhouse temperature should be 15-20 degrees. If the temperature drops after watering, the root system of cucumber will affect the plants on the ground and there is no timely response. If you choose to water in cold weather, please remember to water the green shed in the morning and then cover it with plastic film, so that the water on the ground is not easy to evaporate, the soil is moist and the pests and diseases can be reduced.

In fact, many farmers also grow their own cucumbers. Everyone thinks cucumber is a very simple thing. It seems simple, but in fact it is very important, and every step of planting cucumber must be paid attention to. Watering can't be ignored, especially the problems you should pay attention to. Plantations must know.
