Planting and maintenance of family potted flowers I

Family flower cultivation knowledge-family flower cultivation and watering suggestions: choose natural water sources such as lake water and river water to water flowers. If tap water is used, it should be left for more than 24 hours. Family gardening and watering should follow the principle of "seven more and seven less": 1, more herbs and less woody. Flowers have shallow roots, poor water absorption capacity, large water demand in the body and rapid evaporation of leaves, so water should be more and more diligent. In summer, besides daily watering, foliar water should be sprayed. Woody flowers have deep roots, wide distribution, strong water absorption and less watering. Generally, water every other day in summer 1 time. 2. Water more wet flowers, less dried flowers and less dried flowers: water more wet flowers, such as Dendrocalamus giganteus, Reineckea carnea, Tang Changbo and Eclipta prostrata. However, dried flowers such as cactus, Yu Lian, Nandina domestica, Lagerstroemia indica, sisal and Clivia should be watered less. 3, the leaves are big and soft, and the leaves with wax are watered less. The bigger the leaves, the softer the texture, the easier it is for water to evaporate, so water them more. Ye Xiaoyou has wax flowers, and the water on the leaves evaporates slowly, so you can water it moderately and keep the pot soil from being too dry. 4. Water the sandy soil more, water the clay less. The sandy soil is loose and has poor water retention, so it is advisable to water it more. Clay soil is dense, with good water retention and poor air permeability, so it is not appropriate to water it too often. 5. Water more when it is hot, less when it is cold, and less when it is hot in midsummer and summer. Leaf water transpiration is large, and basin soil dries quickly. Watering should be timely and thorough, and don't water it "half-water". Sprinkle water on the ground and leaves when there is dry and hot wind. In cold weather, low evaporation and winter, flowers grow very slowly or stop growing, so the amount of watering should be less or less. 6. Water more in dry days, less in cloudy days, and the soil is easy to lose water, so water frequently. Water the small pot twice a day, and water the big pot 1 time a day. On cloudy days, the temperature is high, the water loss on the surface of leaves and soil is less, and the amount of watering is less. 7. Water more in the vigorous period and less in the dormant period. Flowers need a lot of nutrients and water to grow vigorously, so we should combine fertilization, water more and water frequently. When flowers are dormant, their growth tends to stagnate, and the water demand is very small, so watering should be strictly controlled. Disease control in family flower cultivation is difficult because it is inconvenient to use pesticides in family flower cultivation. However, we can use some ingenious methods to treat pests and diseases with natural materials around us, which are harmless to people: 1, and spray plant ash leaching solution: soak 300-400g plant ash in 1000g clean water for 2 days, and spray the filtrate on damaged flowers and trees. 2. Onion leaching solution: take 20g fresh onion, crush it, soak it in 1000g clean water 1 day, then filter the solution and spray it continuously for 3-4 times. 3. Garlic juice: 20-30 grams of garlic is mashed, filtered out and diluted with 2000 grams of clear water, which can achieve the purpose of expelling insects, preventing diseases and killing insects. 4. Tobacco extract: 40 grams of tobacco was soaked in 1000 grams of water for 2 days, and the supernatant was taken. When used, it is diluted with 1000g water and sprayed with branches and leaves to control aphids and red spiders. Root irrigation can control nematodes. 5. Pepper water: 50-100g of pepper is boiled with water, cooled and sprayed with branches and leaves to prevent aphids and red spiders. 6. Detergent: Mix a teaspoon of detergent (or soap or washing powder) with 2000 grams of water, and then wash or spray branches and leaves. But be careful not to pollute the soil. The method is simple and effective, and has no toxicity or harm to people and no pollution to the environment. Planting flowers and grass indoors can not only beautify the living environment, but also help people resist the pollution of indoor harmful substances and damage to human health. These flowers and plants can be called "environmental guards" in human rooms. Cactus and cactus can absorb carbon dioxide and harmful gases in the air and release oxygen and negative oxygen ions. Chlorophytum is an expert in purifying air. A pot of chlorophytum can absorb volatile gases such as carbon dioxide, sulfur dioxide and chlorine peroxide within 24 hours. At the same time, it can absorb 96% carbon monoxide and 86% formaldehyde. Hupilan can absorb nitrogen oxides and methane gas. Commelina communis has a strong ability to absorb sulfur dioxide. Aloe can absorb 90% formaldehyde in air 1 m3. Agave can absorb 50% formaldehyde and 24% trichloroethylene. Ardisia, Ivy and Chrysanthemum can decompose formaldehyde in carpets and thermal insulation materials and plywood and xylene in wallpaper. Under the condition of 24-hour illumination, ivy can also absorb 90% benzene contained in 1 m3 air. Red stork can absorb xylene, toluene and ammonia in chemical fiber and paint. Dracaena and daisies can remove trichloroethylene. Magnolia grandiflora, Osmanthus fragrans and Chimonanthus praecox can absorb a lot of mercury vapor in the air. Pomegranate flowers can reduce the lead content in the air. Peppermint not only can resist ozone, but also has bactericidal effect. Rhizoma arisaematis can absorb 80% benzene and 50% trichloroethylene in the air. Whelan can effectively absorb fluorine and sulfur dioxide in the air. Rutaceae plants such as kumquat, chrysanthemum and cinnabar are rich in oil bracts, which can inhibit bacteria, effectively prevent mold and prevent colds. Eucalyptus, asparagus, spurge and cactus can kill germs. Asparagus can also remove heavy metal particles. Ivy, fig, Penglai banana and aloe can not only deal with harmful substances such as bacteria brought back from outdoors, but also absorb dust that is difficult for even a vacuum cleaner to absorb. Phyllostachys pubescens, Eupatorium odoratum and Eupatorium odoratum can absorb more than 80% of indoor harmful gases. Citrus, rosemary and chlorophytum can greatly reduce bacteria and microorganisms in indoor air. Roses can absorb more harmful gases, such as hydrogen sulfide, benzene, phenol, hydrogen chloride, ether and so on. Wisteria has strong resistance to sulfur dioxide, chlorine and hydrogen fluoride, and also has certain resistance to chromium. In order to make potted flowers overwinter safely, flower lovers can take different conservation measures according to the different kinds of flowers they raise.
