1 Select arable land, preparation of nutritious soil Zucchini on the soil requirements are not very strict, but should not use the former planted cultivars of arable land planted species, should choose a lower groundwater level, convenient irrigation and drainage, loam or sandy loam winter fields, and local Nursery, easy to transplant. When growing squash, the growth of seedlings is relatively large. Therefore, the nutrient soil requirements during seedling raising are also more stringent. They must be rich in organic matter, complete nutrition, no grass seeds, few pathogens, and few eggs, pH 5.5 to 7. Therefore, the use of finer ploughing layer soil, every 100kg put pigs, cattle manure 30kg, compound fertilizer 2kg, Baoguo biological fertilizer soil inoculant 3g or 50% carbendazim 10g, fully mixed and stacked for 15 to 20 days. Each nut has enough nutritious soil 700-800kg, nutrition cup 2200.
2 Use good seeds to cultivate strong seedlings
2.1 The selection of fine varieties of zucchini winter cultivation to choose early maturation, short vine, low temperature, disease-resistant varieties, such as hybrids early green. The amount of 0.3kg per mu is about.
2.2 Timely sowing and planting seedlings are scheduled from late November to early December so that tender melons can be harvested in the middle and early February to supply the Spring Festival and early spring markets. Before sowing, the seeds were placed in warm water of about 55°C and stirred for 15 minutes and then soaked for 8 hours. The mucous membranes of the seed coat were then washed off with warm water. The seeds were removed and wrapped in gauze. The seeds were germinated at a constant temperature of about 30°C. The seeds can be sown when exposed. When sowing, put the nutrition cup first on the seedbed, put the nutritious soil into the nutrition cup, make the nutrient soil 1cm from the cup, then compact it by hand, water the water, sowing 1 seed per nutrition cup. , cover soil 1.5cm. Then insert bamboo sticks and cover the film to keep warm. Strong seedlings are the foundation of early maturing and high yielding. The purpose of breeding seedlings is to cultivate strong seedlings. Management should pay attention to inspections, such as water shortages. Zucchini strong seedlings standard is: 3 to 4 leaves, plant height 10 ~ 12cm, stem thick 0.5 ~ 0.6cm, no upper section, leaves smaller, leaf color green, petiole length is equivalent to the length of leaves, seedling age about 30 days .
3 Fine soil preparation, timely transplanting from the 1.6-meter ditch, 30 cm wide, 25 cm deep, and 1.3 m wide. According to line spacing 65cm, spacing 50cm to play acupuncture points, each line 2 lines, about 2,000 holes per acre, fertilizer in the hole, Mushi basal fertilizer: compost home fertilizer 1500kg, superphosphate, ammonium bicarbonate 50kg, potash 10kg, then Cover soil. Transplant from late December to early January. The seedlings are planted for 5 to 7 days before transplantation to enhance the resistance of the seedlings. The temperature at the time of transplantation should be stable at about 15°C, and it should be selected in the morning on sunny days. There should be 1 plant per hole and 2,000 plants per mu. If the soil is too dry, it can be drenched with water or horse water to make the soil moist. After planting, the root water is set, and the membrane is covered with cold.
4 Scientific management, timely melon mining
4.1 Management of fertilizers and waters Care should be taken to eliminate waterlogging, and drought should be used to timely inject horse water or water to promote root growth and development. 8 to 10 days after the melon was harvested, 10 to 15 kg of calcium phosphate and potassium chloride were applied per acre.
4.2 Timely removal of film and cover film to prevent flowering and fruit drop Mainly after 8 to 10 days of transplantation, the cover film is mainly used for heat insulation and frost protection. After that, the cover of the night cover will be opened. However, attention must be paid to weather changes, wind and rain, or cold weather to cover the film in time. . The zucchini is a cross-pollination crop of insect-borne flowers. There is no insect activity in the film, and the humidity is high, which may cause poor pollination and cause fruit drop. Therefore, in addition to removing the film during the daytime, a 2,4-D solution with a concentration of 20-30 mg/kg may also be used. The stalks and the newly opened female pedicels are applied from 8:00 to 9:00 in the morning to reduce flowering and fruiting.
4.3 Strengthen disease prevention The main diseases of winter squash are powdery mildew and gray mold. Powdery mildew damage leaves and young stems, can be sprayed in the early onset of 20% Triadimefon EC 1500 ~ 2000 times or colloidal sulfur 500 times liquid. Botrytis cinerea flowers, young fruit, leaves or larger fruit, at the beginning of the disease with 58% of thiram Mn-Zn 600 to 1000 times or 500 times or 50% of Skoda WP 2000 times Prevention.
4 Timely harvesting usually takes about 30 days after transplanting. The melons weighed 500-700g to start melon harvesting, 2 days picking, and melon harvesting 25 days.
Winter Squash Cultivation Technology
Zucchini is a type of gourd vegetable imported from the West. It is also called American pumpkin. It is an annual herb of Cucurbitaceae. In recent years, in the outskirts of Lechang City, Guangdong Province, about 1,500 acres of winter squash are grown per year, and the yield per mu is about 1500 kg. The per mu output value is between 1,000 and 1,500 yuan. Winter species of squash are available for Spring Festival and early spring market, with good marketability, low investment, and high profitability. Its cultivation techniques are:
