Organic manure not only supplies various nutrients for the growth and development of cucumber, but also can reduce soil bulk density, increase soil porosity, and improve soil physical and chemical properties. Therefore, organic fertilizer plays a major role in the continuous high yield of cucumber, activation and improvement of soil.
Second, rational use of chemical fertilizers.
Cucumber has a shallow root system and is relatively weak. Burning roots are caused by high fertilization. Cucumber fertilizer used to eat less meals, the base fertilizer 25-kilograms of ammonium diamine, potassium sulfate 23-27 kg. During the growing process of cucumber, it is necessary to top-dress fertilizer at any time. The total amount of topdressing is 47-53 kg of urea and 52-58 kg of potassium sulfate. The top-dressing time is generally dominated by the early stage. In the late stage of growth, the nitrogen and potassium fertilizers (or fertilization with equal nutrients) are chased once every 7-10 days in combination with irrigation and picking.
Third, spray foliar fertilizer.
The use of foliar fertilizers is generally at the end of the fruiting period, and there are more nutrients in the early stage. After squashing, the required fertilizer is larger, and the foliar spray of new high-fat membrane + Zhuanggu Tilin can supplement the nutrients needed by the plant.
Fourth, the application of biological bacteria fertilizer.
Adding organic fertilizers and biological bacteria fertilizers to appropriately reduce chemical fertilizers is an inevitable choice for the production of pollution-free green foods. The newly-built greenhouses use high-quality organic biological fertilizers of 8 kilograms. The cucumbers grow robustly, sit on many melons and grow long. Can extend the picking period.
