1, oyster mushroom
The technical requirements of cultivating Pleurotus ostreatus in greenhouse are very low, and the reproductive ability of Pleurotus ostreatus is also very strong, so it is easy to manage, just control the temperature. Because the greenhouse temperature is suitable, the number of harvests a year is about 7 times. About 15kg can be harvested each time. To cultivate Pleurotus ostreatus, we should pay attention to the permeability in the greenhouse, ensure a certain amount of scattered light and control the size of the greenhouse.
2. Cream strawberries
There are many kinds of strawberries, but cream strawberries are very popular now. It is precisely because of the temperature difference and variety advantages in the greenhouse that the price of cream strawberries is more than three times higher than that of ordinary strawberries. Cream strawberry does not need to arrange the cultivation details deliberately, and its vitality is relatively tenacious, and the harvesting time is also many times. The profit rate is relatively high, and planting does not require much experience. It is suggested to arrange greenhouse planting projects for beginners.
3. Toona sinensis buds
In recent years, people's familiarity with Toona sinensis has been deepening, mostly because of its high price. In fact, Toona sinensis is expensive because of its high nutritional value, short shelf life, low yield and large market demand. Proper greenhouse planting, the planting technology of Toona sinensis buds is relatively simple, and the market price is relatively expensive.
4. okra
Okra is also a popular vegetable in China in recent years, with high nutritional value. As a healthy vegetable, the market price is also rising year by year. If planted in the greenhouse, the temperature and humidity can be well controlled to create a good growth environment for okra. And if we use the greenhouse to grow okra and sell it out of season, then its profit is also very large.
Matters needing attention in greenhouse planting
1, strengthen ventilation and reduce the shed temperature. When planting vegetables in summer, in order to avoid high temperature obstacles in the greenhouse, vegetable farmers should pay attention to opening all the upper and lower air outlets in the greenhouse, so that the cold air outside the greenhouse can form convection with the hot air in the greenhouse, thus speeding up the discharge of hot air and helping to reduce the temperature in the greenhouse.
2. Use a sunshade net to cool down. When the temperature in the greenhouse cannot be controlled within the range suitable for vegetable growth through ventilation, vegetable farmers had better use sunshade nets to shade and cool down. Vegetable farmers should put down the sunshade net when the temperature in the greenhouse is close to the highest temperature suitable for vegetable growth in the morning, and roll up the sunshade net when the temperature in the greenhouse is lower than the highest temperature suitable for vegetable growth in the afternoon.
3. Spray at noon to cool down. At noon in summer, due to the high temperature in the shed and the large evaporation of leaves, the water absorbed by the roots can not meet the needs of vegetable transpiration. Vegetable farmers can install micro-sprinkler spray in the greenhouse to reduce the greenhouse temperature, increase the air humidity in the greenhouse, prevent the style and stigma of vegetables from drying, promote pollination and prevent vegetables from falling flowers and fruits.
