Summer cucumber is
Selection of good varieties should be used to select disease-resistant, heat-resistant, high-yield varieties. Such as "Jin Za 2", "Jinchun 4", "Zhongnong 8" and "Jinyan 2" and so on. Soil preparation and fertilization: In early June and early July, after the harvest of the former crop, the site was deep-stumpaged, and 10 mu of decomposed organic fertilizer, 5 kg of urea, and 10 kg of potash were applied to Mushi. After the leveling process is finished, a one-meter-wide curtain is made. Sowing seedlings: seeded by live broadcast, 200 grams per mu. First soak the seeds with a mixture of 0.1% carbendazim and 0.1% potassium dihydrogen phosphate for 2 hours, remove them and drain them on demand. The hole depth is 1.5 centimeters. Seeds are sown with 3-4 seeds. The plant spacing is 4060 centimeters per acre. About 3000 points. After sowing, the seeds were covered with 2 cm thick fluvo-aquic soil, and then 48% of the ground water was sprayed with 48% of diazepam in 150 ml of water and 50 kg of water, and covered with a silver-gray mulch. A small amount of water can be poured after the cover film to reduce the temperature and promote seed emergence. After the emergence of the seed, it is necessary to promptly break the membrane to plant the seedlings, check the seedlings, and make up the seedlings, and to control the weak seedlings. Growth management: When the seedlings grow to 4 leaves, they should be seedlings, leaving 2 seedlings per hole. After fixing the seedlings, they shall be trussed and trussed. When the seedlings grow to 25 leaves, they should be topped in time. For all varieties with more collaterals, all the lateral branches below 5 leaves should be removed. After the seedlings reach the melon seat, they should control the seedlings as much as possible. If the drought persists, it can be properly watered 2-3 times. After spraying, 0.2% potassium dihydrogen phosphate was sprayed on the leaves of the plants twice to promote the melons. Into the harvesting period, generally every 5-7 days watered once, every time the water is chased twice, once per mu, 5 kg per mu. Prevention and control of pests: summer sowing cucumbers are susceptible to disease. During the growing period, it is possible to use Pulitsk 700 times solution plus 0.2% potassium dihydrogen phosphate to spray once every 10 days to prevent various diseases. In the event of insect pests such as mites, cockroaches, and leafminers, they can be treated with 50% haze or 10% imidacloprid 1500 times, or with 0.2% abamectin 1500 times and other highly effective and low-toxic pesticides.
