What causes eggplant and melon vegetables to rot in rainy days? First, the plants are waterlogged
Long-term rain will reduce the permeability of the soil and affect the respiration of the roots of plants. If there is water in the soil, plants will be easily waterlogged, which will lead to root rot, death and rotten fruit.
Second, germs are easy to breed in rainy days.
Most pathogens like to breed in high temperature and high humidity environment, such as common soft rot, gray mold, epidemic disease and Sclerotinia sclerotiorum, which often invade from fruits and stems, and these diseases are infectious diseases, which will spread rapidly after the disease occurs.
What should I do if there are rotten fruits in eggplant and melon vegetables? First, we should remove the diseased fruit as soon as possible. The picked diseased fruit should be taken out of the field and buried or burned, which can reduce the spread of the disease.
Second, spray the corresponding pesticides according to the specific symptoms. Pesticides can be sprayed once every 7 ~10 day and continuously for 3 times.
Third, find ways to reduce humidity. Most diseases are prone to occur in the case of high humidity. In rainy season, we should dig drainage ditches in advance to ensure that there is no water in the fields. If the soil is too wet, we can sprinkle plant ash on the soil. Plant ash can't absorb excess water, but also can supplement potash fertilizer to plants, which can enhance the disease resistance among plants.
How to prevent vegetables from rotting? 1, don't continuous cropping. Continuous cropping will lead to the continuous accumulation of pathogens in the soil, which will increase the risk of soil-borne diseases of crops.
2. Apply more organic fertilizer. Organic fertilizer can improve the physical properties of soil and enhance the permeability of soil. The high content of organic matter in soil is beneficial to the activities of beneficial microorganisms and can reduce the risk of crop diseases.
3. Deeply cultivate the soil. Before planting vegetables, deep ploughing the soil, turning the soil and exposing to the sun can kill some germs with the help of low temperature and ultraviolet rays, which can reduce the risk of crop diseases.
4. Refined management. Fine management includes reasonable close planting, mulching with plastic film, ridge cultivation, reasonable pruning and ridging, and intertillage weeding. As long as we do every detail well, we can reduce the risk of illness and harm.
In a word, infectious diseases are the main cause of rotten fruits, and we should give priority to prevention of diseases, and we should spray drugs as soon as possible after getting sick.
