Below the small series of Huinong.com will tell you about the cultivation and cultivation techniques of cucumber. Many friends like to plant open-air cucumbers, but open-air cucumber cultivation is easily affected by the weather, so greenhouse cultivation has become a major form of cucumber cultivation. The following are the technical points of greenhouse cultivation in greenhouse: Germination: Mainly need to first select the full cucumber seeds, soaked in 55 degrees warm water, 10 minutes later, put the seeds into 25 degrees of water, continue to soak for 8 hours. After the fish is removed, the attachment on the surface of the seed should be cleaned and dried. Nursery: Seeds are placed in a constant temperature of 27-30 degrees to germination, usually 48 hours to sprout, and the cucumber seeds after emergence can be sown. Transplanting: After sowing, when the cucumber seedlings grow to the heart of the three leaves, the problem of transplanting can be considered. Colonization: Two weeks before planting, it is necessary to turn the soil in the greenhouse for fertilization. In the three or five days before the planting, it is necessary to do the ridge work. Fertilization: The fertilization of the soil in the greenhouse is generally determined according to the fertility of the soil, and the fertilizer is mainly based on farmyard manure. Apply 4,000 kg of decomposed farmyard manure per acre, add 25 kg of urea, 75 kg of superphosphate, 30 kg of potassium sulfate, and carry out the shed operation in time.
