Applying enough base fertilizer is one of the keys to stable yield and high yield. Cucumber responded well to the base fertilizer. When the soil was cultivated, the deep-fertilized and applied organic fertilizer was applied. The application of 2000 kg-3000 kg, 50 kg of hair fertilizer and 30 kg of superphosphate were used as base fertilizer. When the plants are 2-3 pieces of true leaves, they start to topdress. Cucumber roots have weak absorption and are sensitive to high-concentration fertilizers. The topdressing method is based on the principle of "diligence and thin application". The topdressing is applied once every 6-8 days, and the urea is applied in 5 kg-6 kg.
When the tendrils appear, combined with cultivating and weeding, the soil is fertilized, the first batch of melons is harvested, and then the soil is fertilized once, the peanut bran is 15 kg-20 kg, the compound fertilizer is 30 kg, and the potassium fertilizer is 10 kg.
In summer and autumn, due to high temperature, rapid growth and development, aging is also fast, coupled with large rainfall, loss of fertilizer and water, in addition to the application of base fertilizer, early topdressing. 1-2 pieces of true leaf stage and after harvesting the first batch of melons, the soil should be fertilized once, and the phosphorus and potassium fertilizer should be paid attention to avoid steepness and premature aging.
Spring cucumber seedlings should control moisture. The flowering period requires the most water. On a sunny day, it is usually drenched once a day, and the drought is irrigated once every 3-5 days. Do a good job of flood prevention in rainy days.
Grow lighting can be one of the most essential factors to successful plant production in a commercial greenhouse because grow lights help to lighten shady spots and propagation areas in the greenhouse. If you are growing tropical plants, you may need to set up grow lights if the plants don't get at least eight hours of sun each day. Most crops benefit from supplemental lighting, when increased growth and quality is converted into added revenue. We provide Growing Light and complete systems for your greenhouses.
