How to plant zucchini?

How to plant zucchini? Please give an introduction to the cultivation of zucchini can refer to the following methods: first, the variety selection of pollution-free zucchini production, requires the selection of dwarf, short vine, strong upright high-yield varieties, such as early green Ⅰ generation, Atai generation, Jasper zucchini and other varieties. Second, the cultivation of strong seedlings of winter and spring zucchini is generally sown from late September to mid-October, mostly using grafting seedlings, the rootstock is pumpkin, using the method of relying on grafting. Before sowing, soak the seeds in warm water, sow them in a well-made seedbed, pour enough bottom water, and cover about 1.5 cm of nutritious soil. When the cotyledons of young seedlings are exposed, the seedlings are divided and planted in a nutrition bowl to strengthen the management of fertilizer and water and cultivate strong seedlings. Third, timely setting seedlings in solar greenhouse zucchini in winter and spring are generally planted from early November to early December. Before planting, 5000 kg of high-quality mature fertilizer and 50 kg of diammonium phosphate were applied per mu, and the soil was deeply ploughed after fertilization. Planting should be carried out on a sunny day in the morning, and the planting depth should be 1 cm and 2 cm. After planting, cover plastic film in time and pour enough water. Fourth, the management after planting. 1. Temperature management: after planting zucchini in winter and spring, the temperature was kept at 25: 30 ℃ in daytime, and decreased appropriately after slow seedling, 20: 26 ℃ in daytime. The temperature of the plant should be raised properly after sitting melon, 25: 30 ℃ in the daytime and 15: 20 ℃ at night. When the temperature is more than 30 ℃, the greenhouse should be closed when the temperature is below 20 ℃. When the temperature is about 15 ℃, the grass should be put down to keep warm. After the beginning of spring, the weather is warmer, so it should be ventilated and cooled at noon. In order to increase indoor lighting, a reflective screen can be hung at the rear. 2. Fertilizer and water management: from planting to root melon swelling, fertilizer and water should be controlled and avoided. When the root melon grows to about 10 cm, it is watered and 20-25 kg per mu of compound fertilizer is applied with water. Results during the period, the watering times and amount of water should be increased gradually, and 500 kg of rotten human feces and chicken manure should be applied at intervals. According to the growth strength of zucchini, foliar topdressing can also be carried out. Carbon dioxide fertilization in the greenhouse in winter and spring also has an obvious effect on increasing production. 3. Artificial pollination: artificial pollination is needed to grow zucchini in the greenhouse. Before 11:00 in the morning, each male flower can be pollinated with 3 or 4 female flowers. In order to prevent poor fertilization, two days before the female flower blooms, 20 × 30 mg / kg 2female D is needed to dot the flower. 4. Plant adjustment and vine pressing: after picking 3 or 4 fruits per plant, the plant enters the full fruit stage, often due to insufficient nutrient supply and poor environmental conditions, the disease is easy to spread, resulting in premature senescence. At this time, it is a critical period for plant adjustment and vine pressing. first, a row of melons is left on each border, and the other row of melons and their plastic film are removed together, and 25 kg of diammonium phosphate per mu is sprinkled on the empty border surface. On the rearranged border surface, open a small ditch about 4 to 5 centimeters deep, remove the diseased leaves and old leaves at the base of the melon seedlings, spray 58% metalaxyl manganese zinc 500 times solution, press the stem vine at the base into the open ditch and cultivate the soil to fill it. 5. Management after pressing the vine: after the stem vine is buried in the soil, the plant is well ventilated and transparent, the disease occurs lightly, and a large number of adventitious roots are produced quickly, with strong absorption to fertilizer and water and exuberant growth. each plant can bear 3 and 4 melons at the same time, and harvest in time when the weight of melon is about 0.3 kg. At the same time, the management of fertilizer and water should be strengthened, 6kg urea should be applied every one month, and Huifengman and other foliar fertilizer should be sprayed outside the root. The main pests are aphids and whitefly, which can be controlled by 1500 times of aldicarb, and the diseases are powdery mildew and virus. 25% trimethoprim and 20% virus A can be used for spray control.
