Cucumber likes the soil with high content of organic matter, loose and permeable; cucumber has shallow root system, likes fertilizer and is not resistant to fertilizer, and the application of base fertilizer should be mainly farmyard fertilizer.

It was determined that n 1.9-2.7kg, p2o50.8-0.9kg, K2O 3.5-4.0kg should be absorbed from the soil for every 1000kg cucumber production. The ratio of the three is 1:0.4:1.6. In the whole growth period of cucumber, potassium was the most needed, followed by nitrogen and phosphorus.

① Base fertilizer:

Mature or high-quality organic fertilizer (soybean 70) shall not be less than 4500-6000 kg (if it is a new shed or higher yield, the application amount shall be further increased), and balanced compound fertilizer 70-80 kg / mu sulfur based compound fertilizer shall be applied.

② From planting to flowering and fruiting stage:

The application of foliar fertilizer can promote the development of root system, promote the growth of leaves and cultivate strong seedlings

③ Early results:

In order to promote plant growth and root development, trace elements were added to improve fruit setting rate and fruit quality. Application of 5-10kg / mu (20-20-20) water-soluble fertilizer (fruit setting stage). High potassium (14-14-30) water-soluble fertilizer was applied once for a long time, 5-10kg / mu.

④ Full fruit period:

In order to promote the expansion and elongation of fruit, ensure the health and strength of root system and plant, improve fruit yield and guarantee fruit quality. 10 kg / mu / time of high potassium water-soluble fertilizer (18-6-30) and balanced water-soluble fertilizer (20-20-20). Attention should be paid to the alternative use of high potassium and balanced water-soluble fertilizer, mainly high potassium water-soluble fertilizer.

⑤ End of results:

According to the growth of cucumber, the balanced water-soluble fertilizer (20-20-20) and foliar fertilizer were applied to ensure the later yield and increase the total yield.
