The cucumbers in the greenhouses are weak in roots and have poor absorption, but they have very good fertilizer and fertilizer resistance. Understand the growth characteristics of cucumber, skillfully apply fertilizer, scientific management, and make cucumber high quality and high yield. Nursery nutrient soil requires loose texture, good air permeability, adequate nutrients, and a pH of 5.5 to 7.2. The preparation method refers to the nutrition soil formula of tomatoes. In the preparation of nutritious soil, the addition of 2~3% of the total amount of superphosphate in nutrient soil has obvious effect on promoting the growth of seedling roots and cultivating strong seedlings. Using nursery seedlings, when transplanting, mu is transplanted or rooted with 2 kg of Manchurian spring microbial inoculum, which can stimulate root growth, increase the survival rate of seedlings, and cultivate strong seedlings. Cucumber roots are mainly distributed in the 15-25 cm plough layer, and the salt tolerance is poor. The amount of topdressing fertilizer should not be too large, and the frequency of topdressing should be more, and the principle of “eat less meals†should be mastered. 1, Shi foot base fertilizer. General Mushi 5000 kg of decomposed organic fertilizer (you can use the full spring spring biological starter to fully compost common organic fertilizer), 20-30 kg of diammonium phosphate, 20 kg of potassium sulfate, and 50 kg of superphosphate as base fertilizer. For many years, greenhouses are required to add 2 kg of ferrous sulfate, 2 kg of zinc sulfate, 1 kg of borax, or 2 to 5 bags of Manjuchunyijia boron, and 5,000 bags of Manchurian spring and good bacteria. After the fertilizers are evenly scattered on the ground, they can be used only once to make them work, and the utilization rate is quite high. 2, Qiao Shi set fertilizer. When planting, bio-organic fertilizer is selected as the planting fertilizer, and 40-50 kg of bio-organic fertilizer is generally applied in Mushi. When fertilizing, it can be spread on the ridge line, and then squat, then ridge can be. 3, growing fertilizer during the growth period. After cucumbers are generally planted, they need to topdress 8 to 10 times. After sitting on cucumbers, the yield of cucumbers is basically formed. Fertilization will not only lead to growth, but also increase the yield. Cucumbers were topdressed for the first time in the early stages of melon cultivation. Mushi 7-9 kg (12-15 kg of ammonium sulfate) was applied and 5.8 kg of potassium sulfate was applied. After every 5 to 10 days, water is poured as necessary. The watering should be carried out with fertilizer every other time. Each time, each mu can be filled with water. To ensure continuous high yield of cucumber. It is also necessary to fertilize later. With the harvest of cucumber, nutrients are continuously consumed, requiring stable and long supply of nutrients, neglecting topdressing at a later stage, premature aging of cucumber due to lack of fertilizer, shortening of effective harvesting period, reduction of cucumber yield, and increase of malformed melons such as melons. Cucumber fruit melon after 2? 3 ,, Mushi urea 10? 20 kg, in order to reduce the development of female flowers, promote the growth of cucumber "head" to avoid the appearance of malformed melon. 4, top dressing outside the root. After cucumber is colonized, before flowering, before fruiting melons, and during fruiting period, extra-root dressing is performed. Each mu is filled with 2 bags of spring water and 30 kg of foliar spray to prevent premature aging and reduce malformation. melon.
