First, choose high-quality varieties, grafted nursery should use strong resistance to disease, high yield, good quality winter crown No. 1, Xintai Micoma and other fine varieties, and black seed squash or white seed squash grafting seedlings (need to select stock According to market needs), and before sowing, do a good job of seed disinfection and seedbed disinfection, in order to facilitate the cultivation of disease-free strong seedlings. Second, re-apply organic fertilizer, with the application of biological fertilizer before planting combined with soil preparation Mushi compost chicken manure, cow dung and compost 7-10 cubic meters, and with the application of biological nitrogen fertilizer 2-3 kg, potash 4-5 kg ​​( Add 10-20 times fine soil and mix with organic fertilizer). 3. Cleaning the greenhouses, fumigating the crops before the crops are harvested, thoroughly removing the stubble, deciduous and weeds in the greenhouses; before planting, use aerosols such as chlorothalonil and dichlorvos for closed fumigation to reduce the number of pests and diseases. . Fourth, high ridge planting, under the film dark irrigation in accordance with the north-south direction to make a bottom 90 cm wide, 70 cm wide and 12 cm high ridge, the bottom of the two ridges spacing 30 cm, the upper spacing of 50 cm. Planting two rows of seedlings on the ridges with planting distance of 50-27-30 cm with soil rakes and leaving a watering ridge in the ridge center. After the planting, the mulch with a width of 0.9-1 m was used to cover the seedlings. This will not only help improve the ground temperature and ensure proper water supply, but also reduce the humidity and inhibit the occurrence of diseases. Fifth, scientific fertilizer, reasonable watering fertilizer can not only provide adequate nutrition for plants, but also can effectively increase the temperature and promote healthy growth of plants. 1. When harvesting, it can be used to harvest roots by harvesting No.1, which can promote easing of seedlings, promote the generation of new roots, and make seedlings robust and disease-free. 2. After the root melon is seated, with the water flushing Shi Jian Zhi Bao Biological Fertilizer, or Yan Zhen brand bio-organic fertilizer or Lanshi series of fine fertilizer (the product is divided into multiple, can be flushed according to their own conditions) and other fertilizers, each pouring Apply fertilizer twice in water. In addition, from the beginning of the flowering stage, applying the harvest 800 times every 5-7 days to spray, can increase plant resistance to disease, increase yield and improve quality. 3. Under the premise of watering and planting water, roots are generally not watered before sitting to promote root development. When the root melon grows to 10 centimeters, it begins to water, and melons are poured once in 10-15 days in the initial stage, and water is poured in the middle and later stages of melon 6-8 days. Watering should be selected on a sunny day. After pouring, the temperature of the shed is raised to 32°C-35°C, and then the air is released for cooling and dehumidification so as to prevent disease. Sixth, comprehensive prevention and control of pests and diseases In addition to the prevention and treatment of pests and diseases, in addition to the cultivation of disease-free strong seedlings, strengthen plant adjustment, reduce humidity, high temperature stuffy shed, nutrition control and other measures, during the growth period, the main choice of multi-mycin, Wuycin, agricultural Streptomycin, avermectin and other high-efficiency, low toxicity, pollution-free pesticides symptomatic control, in the rain and snow and fog days can also be efficient, low-mold chemical aerosols timely fumigation control.
