First, use good varieties: It is advisable to use good varieties that are resistant to disease, heat and high yield. Such as: Jinyan 7th, Jinyan 2nd, Lucuo 9th, Jingxu 2nd, Jinza 2nd, Zhongnong 8th, Xiaqing 4th, and Jinchun 4th.
2. Fertilization for soil preparation: From early June to early July, after the harvest, the former crop will be deep-stumbling and the soil will be applied to decomposed chicken manure 2 to 3, 25 to 30 kg of diammonium phosphate, and 15 to 20 kg of potassium sulfate. After finishing, a round arched ridge with a width of 1.4 meters, a width of 0.9 meters and a height of 15 centimeters was prepared for planting.
Third, soaking seed-demand: live broadcast, 200-250 grams per mu. Before sowing, first soak the seeds with 0.l% 50% carbendazim and 0.l% potassium dihydrogen phosphate for 2 hours, remove and drain, and then dig holes on the ridge by 6035-40 cm. The depth of the hole is about 1.5 centimeters. Each hole is sown with 3 to 4 seeds, 2700~3200 points per mu. After sowing, it covers a tide of 1.5 to 2 centimeters thick. Mu is sprayed with vinegar on 48% of the groundwater, 150 ml of water and 40 to 60 kilograms of water, and covered with a silver-gray mulch.
Fourth, plant management: pay attention to the timely rupture membrane seedlings, check seedlings, make-up seedlings, partial tube weak seedlings. When the seedlings grow to 4 to 5 leaves, they will be seedlings, leaving 2 seedlings per hole. After the seedlings are planted, they are inserted into a stand and tied. It is topped when it grows to 25~28 leaves. For species with more collaterals, all the lateral branches below 5 leaves were removed. The upper side branches were immediately topping after seeing the melon, and 1 to 2 leaves should be left on the melon.
Fifth, water and fertilizer management: After sowing, cast a small water, in order to reduce the temperature to promote emergence. After the seedlings reach their roots and sit before the roots, try to control the seedlings. If they continue to be hot and dry, they can be watered 2 or 3 times. Dingmiao can spray 0.3% of potassium dihydrogen phosphate l ~ 2 times, in order to promote the melon. Into the harvest period, generally 5 to 7 days to pour once, every time the two water chase a fertilizer, each mu urea 7.5 to 10 kg. Every application of nitrogen fertilizer 2 to 3 times, can be applied once per acre to spread the compound fertilizer 10 to 15 kg.
Sixth, pest control: summer sowing cucumber easy to disease, during the growth period can be 80% of Dasheng M, 45 or 72.2% Prec 600 ~ 800 times + 500 times the potassium dihydrogen phosphate mixture, spray once every 10 days or so. To prevent diseases and ensure high quality and high yields. For example, locusts, cockroaches, leafminers, etc., can be sprayed with 50%, or 10% imidacloprid 2000 times, 0.2% zirconia 1500-2000 times, and other highly effective and low-toxic pesticides.
