Different vegetables require different methods of grafting. When cucumbers and other melon vegetables are grafted in a small amount, they can be connected by a grafting method. When a large number of grafted vegetables are grafted, the plugging method should be used. Eggplants and bell peppers should be grafted on the grafting method, while tomatoes should be on the grafted method. Grafting method of cucumber grafting depends on the connection method, plugging method and splicing method. The first two methods are simple, easy to manage, and have high survival rate. The splicing method is difficult to manage and the survival rate is low, so it is less applied in production. In the late 1980s, Shouguang farmers used grafting to graft melon crops; in the 1990s and 2003, they basically adopted the connection method; after 2003, with the rapid development of industrialized grafted seedlings, a large number of plugs were used. Connected, but both of these grafting methods have improved. The method of connection: the method of connection, also called tongue-connected method, consists of grafting the scion and rootstock seedlings under the cotyledons, and then removing the top buds of the rootstocks and planting them in a nutrient bowl (or inside a nutrition cube). Use their own roots to absorb nutrients, cut off the roots of the scion after the survival of grafted seedlings, that is, become grafted seedlings. Shed room preparation. Winter cucumber, winter cucumber, winter cucumber, etc., are usually used to build grafted seedlings in indoor nurseries in winter and greenhouses. About 15 days before sowing, the greenhouses should be leveled, filled with basal fertilizer, deep-sloped, and flooded. Then the surface of the ground, walls, the surface of the film and a variety of building materials spray sterilization, then tightly sealed greenhouses for 10 days, high temperature stuffy shed. When the temperature is high, the highest temperature in the shed can reach more than 7?1, which can kill a variety of germs. For many years, the greenhouses are replanted with vegetables, and the soil is disinfected before the high-temperature stuffy sheds are used for soil disinfection or combined with high-temperature suffocating smoke. Seedbed set. Grafting cucumber to set up three seedbeds, cucumber seedbed, black squash or pumpkin seedlings No. 1 sowing seedbed, planting seedlings grafted seedlings. Cucumber seedbeds and sunspot pumpkin seedlings are built in east-west direction with a width of 120 cm and a height of about 7 cm above the ground. The length can be determined by the number of seedlings. The cucumber seedbed is best built near the entrance to the shed to facilitate ventilation. Pumpkin seedlings need high temperature, the seedbed should be built inside the shed. Grafted seedlings are planted in beds facing north and south to a width of 120 to 200 centimeters and about 7 centimeters above the ground, depending on the amount of seedlings. The nutrient soils of the 3 seed beds should be mixed well with 3 fertile sumtian soils and 1 rotten manure, and 400 to 500 grams of urea and 5.6 kilograms of grass ash should be added to each cubic meter of nutrient soil. Human sheds are built indoors to build nursery beds. Seed treatment. The cucumber seeds were exposed to sunlight for several hours to accelerate the water absorption process of the seeds during soaking. The seeds were then soaked in water at 55°C. When stirring soak, keep stirring until the water temperature drops to 25°C. Remove the mucus from the seed surface by hand, drain the water, and soak in warm water at 25°C for 6 hours. Then remove the seeds in a clean gauze bag that has been scalded with boiling water, and cover the mulch and place it in an environment of about 25°C for 1-2 days. Wait until 70% of the seeds are exposed to white buds (radical roots). Can sow. In order to prevent seedling diseases such as cucumber damping-off, blight, and epidemics, soaking seeds for 6 hours, soaking seeds with 72.2% Precike or 25% metalaxyl WP 800-fold for half an hour before germination . When soaking cucumber seeds with hot water, special attention should be paid to the amount of water not to be excessive. It is advisable to submerge the seeds and keep the stirring to prevent the seeds from being burnt. Palm Recognition Access Control Shenzhen BIO Technology Co.,Ltd. , https://www.huifantech.com
