Autumn leaves are often caused by high-temperature droughts, heavy rain, typhoon, and other severe weather, combined with frequent pest damage. Therefore, autumn leaves are not only difficult to cultivate, but also cause serious pesticide contamination. In order to effectively protect the health of the people and ensure that everyone eats vegetables at an early date, the agricultural technology promotion department of Sheyang County in Jiangsu province has successfully explored and tested a series of new technologies for the organic cultivation of summer autumn leaves and autumn vegetables. The area for organic vegetable cultivation in the county has now been developed. To more than 40,000 mu, summer average output value of more than 6000 yuan per mu, economic, social and ecological benefits are significant, its technical regulations are introduced as follows: full coverage of insect nets, the entire growth period without chemical pesticides. It is usually started in early April to build a pest control net, covering the entire summer and autumn, to avoid the invasion of cabbage caterpillars, yellow strips and other pests. The full use of bio-organic fertilizer does not require chemical fertilizers throughout the growing season. Due to the short growth cycle of leafy vegetables, organic fertilizer should be used as the mainstay. Usually, the “super large†bio-organic fertilizer is 50 kg per mu and the decomposed farmhouse fertilizer is 500 kg. Appropriate batch sowing, adhere to a balanced listing. Summer and autumn vegetables are usually harvested 25 days after they are sown. The vegetable field should be selected fertile, loose, sandy soil near the water source, advance soil whitening, adequate base fertilizer in advance, and then digging Jian Jian, leveling. If the weather is too dry during the broadcast, it must be watered and smashed before the evening of the day. Generally 1.5 kg per mu sowing (preferably to search for high-quality heat-resistant varieties such as Green Star), after the broadcast shallow shoot real, so as to protect the seedlings to emerge. Full use of clean water, stick to pouring hard Qin Qin. Due to the high temperature and dry season, the soil moisture evaporates quickly, so it is necessary to supply sufficient water in a timely manner.Generally, the seedlings are sprayed once a day with a watering can once-two times; Pouring water once (conditional best use shade net, which has cooling and moisturizing effect).
