A survey conducted recently in the countryside has found that the sweet peppers planted in greenhouses have a large area of ​​death and death. The rate of dead seedlings reached 27%, and the highest rate was 64%. Individual sheds were used to destroy other crops. The cause of death was analyzed as follows:
1. Rainwater canopy. The survey found that the common feature of the greenhouses with high mortality rates was that they were all rain-shedd after planting, resulting in serious root rot and stem rot.
2. Improper watering time after planting. The time for watering the individual greenhouses before and after noontime caused the difference between the water temperature and the ground temperature to be too large, resulting in injury to the base of the stems, causing diseases and causing dead seedlings.
3. The occurrence of the disease. When the planting was continuous cloudy, the planting water was poured too much, resulting in epidemic diseases in the shed, resulting in dead seedlings.
Prevention:
1. Open drainage ditch around the greenhouse to reduce the infiltration of rainwater outside the greenhouse into the soil in the greenhouse.
2. Dead sheds were found in the light sheds and the dead seedlings were removed in time and replanted.
3. Pay attention to the time of colonization and avoid planting at high temperatures at noon, causing injury.
4. Adding Dixon and other agents to treat soil during site preparation will reduce the spread of soil-borne diseases.
5. Strictly control the amount of watering, moderate watering, and create a good root growth conditions.
6. After colonization, Shiler + Jinlei or Bacillus subtilis can be used for rooting.
