There are new ways to increase crop production in greenhouses
First, winter cultivation, should use cold-resistant, solid resistant storage, dark green varieties. Before seeding, seed dressing with a new high fat film (which can be mixed with seed coating agent) can repel insects in the ground and isolate virus infection without affecting the function of germination and ingestion, enhancing respiratory intensity, and increasing seed germination rate. Select loose texture, fertile soil, deep soil layer to raise seedlings, strengthen fertilizer and water management at the seedling stage, dilute the ground with small water, apply thin fertilizer, and cultivate strong seedlings.
Second, the winter planting, before planting, with full maturity farmyard fertilizer 80-100 Tam, evenly spread. At the same time, lime is added per acre, shallow ploughs are used, fertilizer, soil and lime are mixed evenly, and then soil preparation is performed.
Third, to close the plant properly, and timely distribution of vegetables with strong stems, can make plant stem thick, thick leaves, fresh leaves, plants lush, strong natural taste. At the same time, it can increase the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual poisons.
Fourth, in case of low temperature weather, double or multi-layer film is used to prevent freezing damage. At noon on a sunny day, the shed film was uncovered and the air was ventilated to reduce the humidity. Before planting ridges, pour watered feces 2-3 times. After ridge sealing, apply urea solution once.
V. Prevention of pests and diseases. In the seedling stage of celery, new high fat film is sprayed to prevent the occurrence of disease. In winter, after the insulation of the shed, the fumigation is used to control pests and diseases, and the effect is good.
