Cucumber is a vegetable that likes fertilizer and water, and it is also a shallow root crop. Lack of fertilizer and water will constitute a sharp mouth melon, melon expansion when water is too much, easy to form a big belly melon. Generally, from planting slow seedling to harvesting root melon, irrigation and topdressing twice, topdressing fertilizer urea or diammonium phosphate 10 kg per mu, and watering water after covering soil in pit. After the root melon is harvested, it is necessary to add the amount and frequency of topdressing. Fertilizer was applied once every 7-10 days, and human manure and chemical fertilizer were replaced. Diammonium phosphate or urea was applied 15 kg per mu and irrigated after hole application. At the same time, water should be poured every 3-5 days. It is usually the replacement of fertilizer and water, that is, one clear (water) and one fertilizer (water), replacing irrigation. Results in the later stage, the ability of absorbing fertilizer and water was decreased. Water was irrigated every 7-8 days and fertilizer was applied every other time. In order to maintain the leaves, foliar topdressing was carried out in combination with spraying. The 100 kg solution was sprayed with 1 kg urea and 1.5 kg brown sugar.
Attention should be paid to the following: irrigation should not be carried out on cloudy and rainy days, because the seedlings can not carry out photosynthesis in rainy days, and the humidity in the shed is high after irrigation, and the wind and moisture can not be released, which will simply cause diseases and overgrowth of melon seedlings. The best irrigation time is in the morning of sunny day, not in the afternoon, dusk and afternoon. The temperature in the greenhouse is high at night and the disease is easy to breed. Irrigation should be carried out before picking the melon. After picking the melon, the empty seedling should be irrigated.
