Greenhouse vegetables should be increased with organic fertilizers. Organic fertilizers can improve soil structure, enrich soil microorganisms, and increase soil fertility, fertilizer supply, and livestock water capacity. Moreover, based on basal fertilizer, 5000 kg of organic fertilizer is applied per acre to facilitate future production management and reduce or avoid the harm of secondary salinization of soil in the shed. When using chemical fertilizers, pay attention to deep application, and do not apply excessive amounts of fertilizer. No fertilizer application is allowed in the shed. After mastering these fertilization principles, producers can top-dress according to the type of crop, different growth stages and individual growth. If you are top-dressing in the cold season, you should pick it up at noon on sunny days. After dressing, it should be ventilated for 1~2 hours until the water on the leaves is dry. Where conditions permit, carbon dioxide fertilization can be performed to increase production.
The irrigation of greenhouse vegetables is better with drip irrigation, which can not only save water, but also reduce the humidity in the greenhouse. If there is no drip irrigation facility, it can also be watered or furrowed. In the cold season, try not to ditch irrigation, watering must also be carried out in the sunny noon, open the ventilation after irrigation, the best combination of irrigation and topdressing. If the soil in the shed is very dry, it does require furrow irrigation, and it is not until the weather is good enough to furrow. When furrow irrigation, water can't drown the surface. Xiao Yuping
