Growing vegetables in glass greenhouses
Glass greenhouses provide an optimum growing climate. In winter there will be gas-fired heating equipment, and cooling pipes are installed by means of picking railcars and column hangers. In summer there is a natural ventilation system and high pressure spraying system to regulate the indoor temperature and humidity.
General glass greenhouses are suitable for growing greenhouses are more suitable for growing anti-seasonal vegetables, such as tomatoes, bell peppers, cucumbers, okra, parsnips, strawberries and so on.
Strawberries
The price of strawberries itself is high, and the overall return is still good. Generally speaking, the picking period of greenhouse strawberries can be extended from December of that year to June of the following year. Now set picking, sightseeing tourism as one of the strawberry base is very popular, glass greenhouse is more suitable for combining this kind of business to operate.
Tomatoes
Glass greenhouse planting tomatoes without any problems, except that the construction of glass greenhouse investment, relatively than the traditional solar greenhouse to be much larger. But the yield of glass greenhouse planting is also very large, can do 70 kilograms per square meter.
Awabi
Awabi is also better to grow, the temperature of 20 degrees can be planted okra. Moreover, the price of okra is quite a bit higher, usually priced at 7-15 yuan/catty, a price that is 2-3 times that of ordinary vegetables! The greenhouses can realize winter planting and precise temperature control, which is very suitable for the growth of okra for the season.
Glass greenhouse planting vegetables technical points
①Planting carrier
Greenhouse growers are using agricultural rock wool or coconuts as a planting carrier, avoiding soil-borne diseases as well as insect pests. As a result the vegetables grown use less pesticides and are of higher quality and safer.
At the same time, the planting greenhouses are only responsible for planting, and there are professional nurseries to provide seedlings to them, shortening the nursery time to improve the production cycle.
②Water Fertilizer Integration
Water Fertilizer Integration Technology is a new agricultural technology that integrates irrigation and fertilization. Soluble solid or liquid fertilizer, according to the soil nutrient content and crop types of fertilizer laws and characteristics, blended into a fertilizer solution with irrigation water.
Drip irrigation water and fertilizer integration, directly to the fertilizer crops need, with the water evenly transported to the roots of the plant, greatly improving the utilization rate of fertilizer.
This can reduce the amount of fertilizer by 50%, and the amount of water is only 30%-40% of furrow irrigation. The switch of water and fertilizer are all realized by controlling the switch of solenoid valve through the data analysis of sensor and computer terminal.
