Fertilizer management in the late growth stage of cucumber

Cucumber is a hi-fert vegetable and a shallow-root crop. In the fruiting period, the supply of fertilizer and water is based on the principle of “eat less and eat more”. If the fertilizer is insufficient, the tip of the melon will form. When the melon is inflated, the water will be too much, and it will easily form a big belly. Generally, from the planting slow seedling to the root melon harvesting, two irrigation and topdressing are carried out, and the fertilizer is applied with urea or diammonium phosphate 10 kg, and the soil is filled with water after the pit is applied. After harvesting, the root melons enter the growth period, and the amount of fertilizer and water needed for the plants is significantly increased. It is necessary to increase the amount and frequency of topdressing. 7-10 days to catch a fat, human excrement and chemical fertilizer alternately applied, apply 15 kg of diammonium phosphate or urea per acre, and apply water after the application. At the same time, water is poured every 3-5 days. Usually it is fat and water alternate, that is, one clear (water) and one fat (water), alternately watered. As a result, the ability of the plant to absorb fertilizer and water was reduced, and water was poured every 7-8 days, and the fertilizer was chased once every other time. In order to protect the leaves, combined with pesticides for foliar topdressing, 100 kg of chemical solution is added with 1 kg of urea and 1.5 kg of brown sugar for foliar spraying.

When filling the water, it should be noted that it should not be watered on cloudy or rainy days, because the rainy day can not be used for photosynthesis. After irrigation, the humidity in the shed is large, and it can not be ventilated and drained, which is easy to cause diseases and melons. The best time for irrigation is on a sunny morning. Do not water in the afternoon and evening or afternoon. The temperature in the shed at night is easy to breed. The irrigation should be carried out before picking the melon. After picking the melon, the water is poured into the air, which is easy to cause the madness.
