The climate is hot in the hot season and vegetable production is relatively difficult. However, in difficult situations, if we can actively focus on production and achieve scientific management, we can often obtain better benefits. I. Grab the fast-growing leafy vegetables. 1. Cabbage: Pre-planting Mushi Manure 1000 kg, fine soil preparation. Planting a batch of Chinese cabbage every 7-10 days, planting seedlings at the time of planting at the V level, selecting seedlings of more than 100 grams per mu and planting seedlings after sowing. Build a small sunshade shed covering, shade moisturizing. Immediately after emergence, spray dichlorvos 1500 times to prevent and control yellow stripe fleas, use chlorpyrifos 1500-2000 times to control Spodoptera exigua, and timely use carbendazim, thiophanate and other drugs to prevent diseases, such as the occurrence of soft rot can be used for agricultural streptomyces 2000 times or 800 times the root rot spirit splash or spray control. Apply fertilized thin manure plus appropriate amount of ammonium bicarbonate or urea once every 7 days. 20 days after the general sowing of Chinese cabbage, it can be harvested and marketed. The yield per mu is 1000-1250 kg. 2. Xia Da cabbage: Summer cabbage can be sown from May to August. The varieties are selected from Xiayang or Xiafeng, which has good early heat and heat resistance. Apply 1500 kg per acre of composted organic fertilizer, 30 kg of ternary compound fertilizer, mix with field soil and plowing, use deep sorghum cultivation, (if you can do drainage work, use yin to cultivate cabbage more conducive to the growth), per mu seedlings About 4500 strains. Fertilizer timely supply, timely control of pests and diseases (the same measures as the Chinese cabbage). Harvested 45-60 days after sowing. The yield per mu is 2000-2500 kg. Second, a reasonable intercropping intercropping 1, spring corn intercropping summer Qiuqin: In early July in the inter-row corn line Mushi organic fertilizer 1000 kg, three yuan compound fertilizer 15 kg, and then site preparation. Seeds of celery before sowing are soaked for 24 hours. The seeds are then placed in a refrigerator or well to moisturize the germination. After the seeds are white, they are spread evenly and covered with a fine layer of soil. After the corn was harvested in early August, it was flooded with fertilizer. Timely use of mancozeb, chlorothalonil, carbendazim and other drugs to prevent celery spot blight, anthrax. It is listed from late September to early October and produces about 2,500 kilograms per mu. 2. Cucumber or tomato interplanting cowpea or kidney bean: In the late growth stage of spring cucumber or tomato planting, 2-3 kernels of cowpea or kidney bean seed are planted on the side of each plant, and when the vine is extended, the former crop is cut off and weeding is carried out. Available fertilizers. Into the flowering stage, spraying dichlorvos to prevent soybean meal in the evening. About 45 days after sowing, they will harvest tender pods and produce 1000-1500 kilograms per mu. Third, strengthen the management of vegetables in the field, prolong the harvesting period of Futian 1. Clearing and digging the trenches: We must do a good job in supporting the field water system and clear the weeds in the ditch. Prevent flood and drop. 2. Appropriate top-dressing: Sheathed solanaceous fruit and melon vegetables are harvested once every time according to the growing trend, or with foliar spray Huimanfeng, plant power 2003, and other growth regulators or potassium dihydrogen phosphate and urea. Prevent premature aging of plants. 3, timely prevention and pest control: eggplant, melons and other diseases, can be used Chlorothalonil, thiophanate-methyl, vegetable Bornein and other drugs to prevent and cure; Virus disease occurs, available plant disease or virus A + bacteria Clear or small leaf enemy + natural brassin and other drug control; tobacco insects, melons, moths, use of chrysanthemum ester, card dead grams, chlorpyrifos, dichlorvos and other drugs prevention and treatment.
