Agricultural control of green pepper rotten fruit in greenhouse

First, the temperature and humidity in the shed are controlled by the traditional method of ground irrigation. A thermometer is placed at each end of the shed. The temperature and humidity in the shed are measured regularly to determine the temperature of the wind and the temperature of the curtain. During the day, the temperature in the shed is controlled at 23 ° C - 27 ° C, the night temperature is controlled at 16 ° C - 20 ° C, and the relative humidity of the air is controlled at 70% - 80%. When the outside temperature is greater than 15 °C, gradually ventilate day and night, put the bottom wind at the front end of the shed, from small to large. Every two meters, a vent is lifted and supported by bricks. When the outside temperature rises to 16 °C on average, the bricks are placed horizontally (10 cm high), and at 19 °C - 21 °C, the bricks are placed vertically (20 cm high). As the temperature in the shed rises, wind and wind are placed, or the shade net is covered. The wind must be stable, and the temperature inside the shed should not rise and fall in a short time.

4. Covering grass and dehumidifying 3-5 cm thick wheat straw or wheat bran between the green peppers can absorb moisture and moisture, reduce the air humidity inside the shed, and inhibit the breeding of diseases. Linyi Fertilizer Network Copyright
