In recent times, local temperatures are not high temperatures or heavy rains. How should greenhouse vegetables be managed under such weather conditions?
1. Discharge in time to reduce the humidity in the field. After the rainfall, if there is a large amount of water in the field or when rainwater is poured into the shed, the water in the field should be removed or extracted in time to reduce the humidity in the field. The land is conveniently located, using well water to water after the rain, breaking the soil canopy and reducing the impact of rain.
2. Draw the appropriate cultivating and break the soil compaction. After the weather turns fine after the rain, proper cultivating according to the soil moisture is beneficial to breaking the soil compaction and enhancing the permeability of the soil. At the same time, the weeding work in the field is completed. For the seedling plot with short colonization time, this operation Particularly important.
3. Strengthen root maintenance and pay attention to the adjustment of plant growth after rain. Open-air vegetables are affected by rainfall, strong winds, etc. Some plants with slings fall off should be slinged in time after rain to restore plant growth. The plants that have been protected from rainwater in the shed are regulated in time according to the growth of the plants. When the plant appears to be prolonged after the rain, it should be timely controlled to control the temperature or control the water to control the growth of the plant. The rooting work is the focus of post-rain management. After rainwater invades the field, the root of the plant is the most influential. For plants with weak growth, rooting can be used or rooted with functional fertilizers to promote the recovery of root growth and absorption. Appropriate spraying of foliar fertilizer is also an important measure to help plant growth, and attention should be paid to spraying.
4. Disease prevention and treatment. After the summer rain, the humidity in the field is high and the temperature is high. The vegetables in the protected area are prone to disease. It is necessary to reduce the humidity in the shed, enhance the growth of the plant and classify to prevent different diseases, spray the agent and foliar fertilizer in time, kill the bacteria in time, and do the disease well. Prevention work.
