Timely repair of salvaged vegetables Yan Congsheng said that after a heavy rain, the temperature tends to pick up quickly. Even if it is not submerged, the long-term accumulation of water and high-temperature and high-humidity environment are very unfavorable to the vegetables on the ground and the disease is aggravated. For those fields that are not severely affected, attention should be paid to the following issues: timely clearing of trenches to eliminate water in the fields and sheds, and for areas with low topography and high inland water levels, organize electric pump drainage, speed up drainage and reduce groundwater levels. Timely sought after victims of vegetables, increase the amount of listed companies suppress the price of vegetables. In order to compensate for the losses caused by the disaster, the heavy-duty vegetable plots must speed up the harvesting of species that have not yet completely drowned. In a timely manner, righting, rooting, rooting, vines, and planting, and if necessary, pouring root water. Prune the broken, damaged branches, vines, rotten fruit, and rotten leaves in time to avoid the spread of diseases. After the rain, the soil is compacted, and when the soil is slightly dry, the cultivator loosens the soil in order to improve the soil structure and improve the vitality of the root system. When the rainstorm is over, the artificial water spray should be performed in time to flush the leaves. Suddenly, after the heavy rain, the weather suddenly rose, and when the temperature rose suddenly, the greenhouse vegetables were promptly shaded and cooled to prevent the transpiration of the leaves from intensifying, and the plants with the damaged roots had insufficient water supply to cause acute wilting. After the heavy rain, the field temperature is high, the humidity is high, the plant resistance is weak, and root rot, wilt disease, downy mildew, and other pests and diseases are easily caused. The diseased plants should be promptly removed and taken out of the field to be buried deeply; Prevention: Root rot and blight can be treated with thiophanate-methyl 700 times to root; downy mildew and epidemic can be controlled by 800 times solution of promecarb or 500 times solution of Kelu; anthrax and powdery mildew can be used to control Difenocarbazole 1500 times or thiophanate-methyl 700 times or ether 1500 times spray control; Bemisia tabaci can use 4% avicidium or bifenthrin 2000 times or 0.3 matrine 1000 -1500 times liquid spray; beans Ye Zi, Plutella xylostella, beet armyworm, Spodoptera litura can use spinosad 1500 times or Ding Long 1500 times solution or 1% Alkali salt 2500 times spray control. Replanting a severely affected plot For the more severely affected fields, Yan Congsheng said that farmers should pick up the shed early after the water is reclaimed for direct seeding or autumn seedlings. According to the exclusion time of stagnant water, early replanting and replanting should be arranged. At present, we must pay close attention to the adoption of live broadcasting methods and sow some fast-growing vegetables and early-maturing fresh foods. Such as no shelf beans, vegetables with soybeans, green beans, chicken feather dishes, water spinach, leeks, fungus, cabbage, cabbage, radish, carrots, spinach, wolfberry, pickled cabbage, garland chrysanthemum, fungus, leeks, vegetables, alone Vegetables, spicy vegetables, red vegetables, fresh corn and so on. For low-lying plots that cannot be drained in time, watercress and cress production can be arranged and can be planted before the end of September. Watercress has one hole per plant, 3 to 4 watercress clusters, 2025cm spacing, 2~3cm water layer in front of the living tree. As the plant grows, the water layer can gradually deepen, but the watercress should not exceed 6cm, cress not more than 30cm. Watercress was harvested in November and cress was harvested in late February of the following year. According to the time of the withdrawal of water, the corresponding facilities for sowing and seedling cultivation in autumn will be timely carried out. In early July, we will enter the nursery stage for sowing vegetables in autumn. At this time, suitable vegetables for sowing include: tomatoes, peppers, eggplants, watermelons, melons, cucumbers, cabbage, Chinese cabbage, broccoli, and cauliflower. After the sowing, shelters such as sunshade nets should be covered with floating surface, small sheds, and sheds, etc. to cool and moisturize, and avoid damage caused by heavy rain. Retreat in early August, the appropriate types of vegetables are pepper, tomato, eggplant, melon, cucumber, kidney bean, celery, autumn cabbage, autumn radish, etc.; before the end of August to retreat, you can change the greenhouse vegetables, such as broccoli, Cauliflower, cucumber, zucchini, lettuce, celery, garlic, etc. Those who have conditions should try their best to adopt net and membrane-covered facilities to avoid rain. The following varieties are available: Tomato: Loquat powder No. 5, Noodle No. 20, Noodle No. 7, Noodle 21, Noodle No. 105; Pepper: Noodle No.1, Noodle No.4, Noodle No.1, Noodle Noodle 18 , Top Big Pepper, Sujiao No. 5, Zhongjiao 106; Eggplant: Round Mixed 16, White Soybean No. 2, Mince No. 2; Cucumber: Jin Bichunqiu, Jinyou No. 4, Zhongnong No. 16; Cabbage: Zhong Gan 9 Numbers, Zhonggan No. 11, Zhonggan No. 19, and Zhonggan No. 22; Kidney Bean: No. 1 Noodle, Noodle Noodle, Selected No Frame, Special Selection No. 28-2; Vegetable Soybeans: Large grain early; Cabbage : Brassica oleracea; radish: bent blue, short leaf 13, fresh white jade spring, Korean root, Jingyan Qiubai, Jinghong No. 3, Zhengyan radish; carrot: new Kuroda five-inch ginseng; fresh food Maize: Huyujing No.1, fragrant purpura, and big jade scorpion. Yan Congsheng reminded growers that there are three things that need to be taken care of. The first is to sow early sowing, the sooner the better, where the water retreats and where to replant; second is to increase the density to cover late; third is to choose the species Fully consider the market demand.
