Protected land cucumber fertilization technology

According to the fertility requirements of cucumber, the cucumber in the protected area must be re-applied with base fertilizer, generally 5,000 to 7500 kg/mu of high-quality organic fertilizer, and 20 to 30 kg of phosphorus and potassium fertilizer. Cucumber is a shallow root system that is shallow into the soil and should be planted shallowly when planted.
Cucumber should be topdressed several times during the growth and development process. The amount of topdressing should not be too large, and a small number of times should be used to chase lightly.
(1) skillfully applying seedling fertilizer: After slowing down the seedlings, the roots are controlled to control the roots, and the roots are promoted as much as possible, so that the amount of fertilizer can not be too large. Generally, 5 to 7.5 kg of urea or 500 kg of decomposed manure can be applied per mu, 5 cm away from the plant, and the soil is covered with water after the ditch is applied.
(2) Re-application of fertilizer: After the cucumber enters the result period, it should be timely filled with fertilizer and water. Generally, 15 to 20 kg of urea or diammonium phosphate is applied in the dark ditch. After the cucumber enters the fruiting period, the fertilizer needs to reach the peak period. During this period, the fertilizer is usually chased every 10 to 15 days. In the dark trench, the ammonium nitrate or diammonium phosphate is applied in an amount of 15-20 kg per mu, or it is decomposed. Excreta is 400 to 500 kg.
