Hot season climate is hot and vegetable production is relatively difficult. However, if we can actively focus on production and achieve scientific management in difficult situations, we can often achieve better results.
I. Grab the fast-growing leafy vegetables
1. Xiaobailai: Before planting Mushi manure compost 1000 kg, fine soil preparation. A batch of Chinese cabbage is sown every 7-10 days. The seedlings in the pre-float selection were better, with 500 grams per acre. Build a small sunshade net shed covering, shade moisturizing. Immediately after emergence, spraying dichlorvos 1500 times liquid to prevent the yellow song strips, with chlorpyrifos 1500 ~ 2000 times liquid control Spodoptera exigua, and timely use of carbendazim, thiophanate and other drugs to prevent disease. If soft rot occurs, use agricultural streptomycin 2000 times or root rot 800 times for sprinkling or spraying. Apply fertilized thin manure plus appropriate amount of ammonium bicarbonate or urea once every 7 days. After 20 days of general sowing of Chinese cabbage, it can be harvested and put on the market. It can produce between 1000 and 1250 kg per mu.
2. Xia Cabbage: Summer cabbage can be sown in May to August. The varieties are selected from Xiayang or Xiafeng, which has good heat resistance and heat resistance. 1500 kg per acre of composted organic fertilizer, 30 kg of ternary compound fertilizer, plowing and mixing with the field soil, the use of deep sorghum cultivation (such as can do a good job of drainage work, the use of puberty cultivation is more conducive to the growth of summer cabbage), mu preservation of 4500 seedlings About the strain. Fertilizer timely supply, timely control of pests and diseases (the same measures as the Chinese cabbage). 45-60 days after sowing, the harvest yields 2000-2500 kg per mu.
Second, a reasonable intercropping
1. Spring corn intercropping for summer and autumn celery: In early July, 1,000 kg of decomposed organic fertilizer and 30 kg of ternary compound fertilizer were planted between the rows of maize and then soil preparation. Seeds of celery are soaked for 24 hours before sowing and 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 or 3 kidney bean or kidney bean seeds are planted on the root side of each plant. After extending the vine, 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, Nenjak is harvested and the yield per mu is between 1,000 and 1,500 kilograms.
Third, strengthen field management and prolong the harvest period
1. Clearing the trenches: We must do a good job in the field water system to clear the ditch and weeds. Prevent flood and drop.
2. Appropriate top-dressing: Sheath planting solanaceous fruit, melon vegetables should be appropriate according to the growth of chase fertilizer, or foliar spray Huimanfeng, plant power, such as 2003 growth regulator or potassium dihydrogen phosphate and urea. Prevent premature aging of plants.
3 timely prevention and pest control: Solanaceous vegetables, melons, a variety of diseases, can use chlorothalonil, thiophanate-methyl and other drugs to prevent and cure; the occurrence of viral disease, available diseases or disease virus A + bacteria poison or lobular enemy + Natural brassin and other drug control; tobacco budworm, melon, moth, use of chrysanthemum ester, card dead grams and other drugs.
