Spring and summer vegetable management technical measures
I. Cultivation and management of protected vegetable crops. For the management of cucumbers and zucchini, it should be combined with the prevention of disease spraying Jinchunbao 2000+ Yunda 120, Solanaceae spraying “whole tree fruit†(GA4+7 and brassinolide complex) to promote growth, followed by cultivation The aisles in the ridges can be used as a step-breaking measure, which can be combined with topdressing organic fertilizers to increase soil permeability and promote root growth. The temperature management is controlled at 26-28°C during the day and 12-15°C during the night. The temperature is too high to increase the ventilation rate. In addition, there will be 1 or 2 times of low temperature weather in the middle and early April. Do not collect cold equipment prematurely to prevent freezing damage to the seedlings. .
Second, pest and disease control. Melon diseases include downy mildew, powdery mildew, epidemic disease, and blight, which can be sprayed with 50% Anker, 72% Best, or 70% Tribeca, 10% Sego, 5% Tride or 50% Gram. Dew, 80% cloud or 35% hymexazol, 50% carbendazim and so on. Solanum leaf mold, leaf spot, and disease can be sprayed with 38.5% Halic, 5% Tsui, 70% thiophanate, 53.8% can kill pesticides; pests are locusts, whitefly, ocher螨 (螨å¶èž¨), Liriomyza, etc., found pests sprayed in time, even sprayed 2 or 3 times, separated by 4 to 6 days, completely eliminated to reduce the greater harm caused by the expansion of vents to open air. Can be sprayed with 25% of scorpion, 5% of peony, 3% of ciprofloxacin, 10% of dilute and so on. Several pesticides are applied alternately to increase the control effect. As a preventive drug, spraying once every 7 to 10 days can effectively control the occurrence of insect pests. The phytotoxicity caused by excessive spray concentration and high temperature can be sprayed by Yunda 120+. White sugar has a good alleviation effect.
Third, the cultivation of open vegetables. Plants cultivated in the open, in early April, live cucumbers Jinlu No. 4 and No. 5, Jinchun No. 4, French ground kidney beans, No. 2 cowpea, Chinese cabbage spring cabbage white No. 3, No. 6, Tianzheng Chunbai No. 1 , Beijing spring green, Beijing spring white, early spring large root radish, etc., to cover the film. Live or breeding seedlings include Xueyuwang, Xueyu 1, 2nd, 6th, and 791th, etc., after seeding, they must be covered with plastic film before the emergence of seedlings, and in the middle of the day, tomatoes, cucumbers, Chinese cabbage and other crops of immature seedlings should be planted. Covering the film with water and promoting mild seedlings, the seedlings must be cultivated at low temperature for 7 to 10 days prior to planting to adapt to the growth of the open field, and Yunda-120+ Methacrylo® sprayed at the same time to improve disease resistance and low temperature resistance.
