How to prevent heavy rain damage
The season is a season of heavy rainfall, which is a critical period for the sowing of autumn vegetables and the growth of vegetables during the summer. At this time, Daejeon’s vegetables are often hit by heavy rain, which leads to a significant drop in yield and quality. If the vegetables that have not emerged soon after sowing have been washed by heavy rain, some of the seeds will be exposed on the exposed surface, some will be flushed to the bottom of the ditch, resulting in the lack of seedlings and ridges; young seedlings will be washed out after rainstorms, exposed to the young roots, After sun exposure, there will be wilting and death. Even with larger vegetables, after a heavy rain, they will suffer different degrees of damage. Therefore, we must do a good job of vegetable control measures.
How to prevent and treat rainstorm damage caused by vegetables in season? For freshly sown vegetables, timely covering with straw, straw, sunshade nets and other coverings after sowing, this can not only shade and protect the seed, prevent the seed from drying out, but also can effectively reduce the erosion of heavy rain, is conducive to the "one seeding seedlings." After storms, the water in the fields was quickly eliminated, the fallen plants were helped, and the soil on the plants was sprayed with clean water to facilitate the photosynthesis and restore the plants as soon as possible. In order to promote the growth of the affected vegetables, fast-acting fertilizers are quickly chased after the rainstorm, and the first foliar spray of a mixture of 0.3% potassium dihydrogen phosphate and 1% urea is used once. When the soil moisture is suitable, the urea is applied to the soil 6~8 per mu. kg. In addition, measures such as strengthening the cultivating loose soil, spraying plant ash, spraying Bordeaux mixture, etc. have good results in promoting the healthy growth of vegetables and preventing the occurrence of diseases.
