Greenhouse cucumber eight bogey

A bogey arbitrarily changes the angle of light in the greenhouse. The angle of the greenhouse in which cucumbers are grown is a long-term scientific demonstration. Its north-south span, height, and back-slope angle should not be arbitrarily changed. Second, avoid concentration of fertilizers when planting a variety of chemical fertilizers, especially nitrogen fertilizers, in the humid high temperature, will produce a lot of harmful gases, such as concentrated application in the planting ditch, can cause cucumber roots die. The third avoid bogey too deep we all know that cucumber grafting is to fight disease, such as planting seedlings too deep, cucumber will produce reproductive roots, loss of grafting effect, can not reach the purpose of grafting. The four bogey rainy days do not pull grass. People often think that the shade, rain, snow, grass pulling, greenhouse temperature will drop, so do not pull grass. In fact, this practice will cause more harm than usual. The temperature will not only decrease slowly, but will also cause physiological disorders due to the long-term absence of sunlight from the cucumber. The five bogey winter large amount of nitrogen fertilizer due to nitrogen fertilizer in the dispersion process, will cause a significant decline in water temperature, promote the ground temperature decreased, affecting the normal growth of cucumber pods. Six bogey applications of organic fertilizer without compost will be fermented quickly after high temperature, in the fermentation process will produce a lot of ammonia, the light decomposition of nitrogen in the greenhouse, can cause all cucumber seedlings in the greenhouse to die. Seven bogey noon afternoon spray spraying at noon temperature is too high in the greenhouse, leaf moisture transpiration fast, the drug has not absorbed, dried on the sun, especially the type of medicine, will cause phytotoxicity. Spraying in the evening is just the opposite of noon, because after the spraying, it is not completely absorbed by the cucumber leaves, and it will decompose and fail due to dampness, failing to achieve the purpose of treatment, but aggravating the occurrence of diseases. Eight bogey and dwarfing one-off louse overdone will make the blade sharply reduce the light area, affecting the normal growth of cucumber pods. China Agricultural Network Editor
