Zucchini pressure vine cultivation technology

Solar greenhouses are generally planted from early November to early December. In the middle and late stages of zucchini growth, due to poor indoor ventilation and light, closed fields, poor photosynthetic capacity, plants are prone to premature senescence and low yields. Therefore, a zucchini pressing technique was introduced.

First, select good varieties

According to the practice in recent years, the early-green generation of high-yielding species with short, short vines and strong uprightness is more suitable for greenhouse growth.

Second, cultivate strong seedlings

In mid-late September, after soaking the seed warm soup, plant it into the prepared seedbed, pour foot water, and cover the 1.5 cm thick nutrient soil. Before sowing, maintain the temperature of 25-30 ° C during the day and 17-20 ° C at night; the temperature of 22-25 ° C during the day after emergence and about 13-15 ° C at night after emergence. When the seedlings show their true leaves, they are divided and planted in plastic nutrition bowls. Strengthen fertilizer and water management and cultivate strong seedlings.

Third, timely colonization

In mid-to-late October, when the seedlings are 30-35 days old, choose sunny days to plant strong seedlings. Deeply plow the soil before transplanting, and apply 5000 kg of high-quality rotten organic fertilizer and 50 kg of diammonium phosphate as base fertilizer. Site preparation for hoeing, the hoe surface is 1.1 meters wide, 15 cm high, and the ditch is 30 cm wide, and then covered with plastic film, perforated and planted, 2 rows per ridge, 65 cm line spacing, 50 cm plant spacing, 2100 plants per acre. Pour enough water into the tree and seal the holes. Maintain high temperature and humidity in the greenhouse 3 to 4 days after planting to shorten the slow seedling period.

4. Management after planting to early fruit period

Results The front shed temperature was controlled at 26 ° C during the day and about 16 ° C at night. As a result, the initial shed temperature was controlled at 28 ° C during the day and about 18 ° C at night. Before the results, the fertilizer and water were properly controlled to prevent excessive growth. After the female flowers were opened, 6 kg of diammonium phosphate was applied to the mu points. In order to prevent poor fertilization, it is necessary to treat with 20-30 mg / kg 2,4-D dot flower two days before the female flower opens.

Five, plant adjustment and pressure spread

After picking 3-4 fruits per plant, the plant enters the fruit-growing period, often due to insufficient nutrient supply, poor environmental conditions, and disease easy to spread, leading to premature aging and affecting yield, and this is the key period for plant adjustment and pressure spread. First select one row of melons on each loquat, remove the other row of melons and the mulch film on them, and apply 25 kg of diammonium phosphate per acre on the empty loquat surface to level the ground. On the reorganized surface, use a shovel to open a small trench about 4-5 cm deep along the melon road, remove the diseased and old leaves at the base of the melon seedlings, and leave strong functional leaves 10-12 on the top of each plant. After spraying 500% solution of 58% metalaxyl manganese and zinc, the stem of the base was pressed into the opened trench, and filled with soil.

Six, post-manual management

After the stem vine is pressed into the soil, the plant is well ventilated and light, and the disease occurs lightly. A large number of adventitious roots will soon be produced. The fertilizer and water absorption will be strengthened and the growth will be strong. Each plant can produce 3 to 4 melons at the same time. Harvest around 300 grams in time. At the same time, the management of fertilizer and water should be strengthened. Every 1 month, 6 kg of urea was applied to acres, and foliar fertilizers such as Huimanfeng and chlorophyll were sprayed outside the roots. Regularly pick the leaves and press the vines. Press the vines once a week. Temperature management and 2,4-D treatment are the same as the initial results.

Seven, pest control

Aphids are sprayed with 1500 times solution of 50% antiaphid or 40% chrysanthemum cream, and virus diseases are sprayed with 20% virus A400 solution or 1.5% plant disease spirit 800 times solution spray. Powdery mildew is controlled with a 25% powder rust spray.

Zucchini pressing is a set of pressing cultivation techniques developed by vegetable farmers in Dongkan Town, Binhai County, Jiangsu, so that the growth period of zucchini can be extended from September * to June the following year, and the yield per mu can reach more than 10,000 kg. For details, please refer to the above cultivation techniques.
