What kind of vegetables are suitable for growing in glass greenhouses (What kind of vegetables are suitable for growing in greenhouses)

Glass greenhouse vegetable planting

The glass greenhouse can provide the most suitable climate conditions for growth. In winter, there will be gas heating equipment, and the heat dissipation pipes will be installed by picking rail cars and column hanging. In summer, there will be natural ventilation systems and high-pressure spray systems to adjust the indoor temperature and humidity.

Generally, glass greenhouses are suitable for growing off-season vegetables, such as tomatoes, bell peppers, cucumbers, okra, toon, strawberries, etc.

strawberry

The price of strawberries is high, so the overall profit is good. Generally speaking, the harvesting period of greenhouse strawberries can last from December of the current year to June of the following year. Strawberry bases that integrate picking and sightseeing are very popular now, and glass greenhouses are more suitable for this type of operation.

tomato

There is nothing wrong with growing tomatoes in a glass greenhouse, except that the construction investment of a glass greenhouse is much larger than that of a traditional solar greenhouse. However, the yield of tomatoes grown in a glass greenhouse is also very high, reaching 70 kilograms per square meter.

Okra

Okra is also relatively easy to grow, and can be grown when the temperature is 20 degrees. Moreover, the price of okra is much higher, generally 7-15 yuan per catty, which is 2-3 times the price of ordinary vegetables! Greenhouses can achieve winter planting and precise temperature control, which is very suitable for the growth of okra in seasons.

Key points of vegetable cultivation technology in glass greenhouse

① Planting carrier

Greenhouse growers use agricultural rock wool or coconut palm as planting carriers to avoid soil-borne diseases and insect pests. Therefore, the amount of pesticides used in the vegetables grown is less, and the quality is higher and safer.

At the same time, the planting greenhouse is only responsible for planting, and there are professional nurseries that provide them with large seedlings, shortening the seedling raising time and improving the production cycle.

② Water and fertilizer integration

Water-fertilizer integration technology is a new agricultural technology that integrates irrigation and fertilization. Soluble solid or liquid fertilizers are mixed with irrigation water according to the soil nutrient content and the fertilizer requirements and characteristics of the crop types.

Drip irrigation integrates water and fertilizer, directly and evenly transports the fertilizer needed by crops to the roots of plants along with water, greatly improving the utilization rate of fertilizer.

This can reduce fertilizer usage by 50%, and the amount of water is only 30%-40% of furrow irrigation. The switch of water and fertilizer is realized by controlling the switch of solenoid valve through sensor and computer data analysis.
