Zucchini cultivation techniques and prevention
With the continuous improvement of people's living standards. People’s food structure has undergone tremendous changes, in order to meet the needs of people’s diversified material life, especially to meet the urgent needs of local winter fresh vegetables, through field surveys, multi-argumentation, to regulate market demand, enrich market products, increase farmers Economic income. Select "Zuoqing generation" zucchini hybrids. 2, nursery method 2,1 seedbed selection. The seedbed must have a fertile soil, a deep soil layer, good water permeability, good air permeability, a sunny leeward, plenty of sunshine, and a convenient water source. 2,2 seedbed finishing. Flat arched nursery. General Mushi rotted farmyard fertilizer 2500kg mixed fertilizer 10kg, superphosphate 30kg, broken to pieces. Width 1m width, with bamboo spacing 50cm arch shed, shed height of about 50cm, shed bottom with plastic film paved, both sides compacted with fine soil and fixed with a rope, the surface with carbendazim 200 times for uniform Spray disinfection, close the small shed 1 ~ 2d after planting seedlings. 2,3 seeding and sowing amount, mu seeding rate of 300g, spread evenly in the whole seedbed, after covering the 1.5-2.0cm mixed fine excrement. 2,4 seedling management. Timely release film cover film, film peeled off during the day, covered at night, keep the soil temperature, to accumulate heat, promote seedlings, 5-7d after sowing, daytime temperature 28 ~ 30 °C, night 18 ~ 20 °C; 70% After -80% of the seeds are broken, the daytime temperature is 20-25°C and nighttime is 15-18°C. After the seedlings are kept, they are maintained at 20-25°C during the day and 12-15°C at night. When the sun is about to reach the greenhouse, the sun must be open for ventilation and cooling. Moisture management: seedbeds can regain moisture at night, and no wilting phenomenon occurs in plant leaves, so as to avoid causing plant growth and causing tall seedlings. If the night temperature is too low or snow and ice weather is needed, blankets or grass must be covered to prevent cold and heat. 2. Transplanting time and raising seedlings When it is determined that there will be no frost in the local area, and that the full flowering period can effectively avoid the “cold springâ€, generally, the transplanting is covered with a mulching film from the end of February to mid-March. Multi-bed seedbed soil, to avoid damage to the seedling root system. Plant spacing 50cm50cm, per plant 2600 or so per acre. Film mulching cultivation, in the middle of the ridge according to the spacing requirements of the ditch or open hole, put the seedlings and buried a small amount of soil to fix the root system, and then watering, water infiltration after the cover soil and Zhuangshi. Planting depth should not be too deep. After the seedlings are planted, the rooting water shall be soaked in time, covered with a plastic film, and the seedlings shall be straightened, and the mulching film shall be compacted with fine soil. According to the planting specifications, the gullies will be planted in a row, with a spacing of 50cm80cm and a depth of 28-30cm. A 40kg compound fertilizer is applied per acre as a base fertilizer, and a small amount of fine soil padding is used to seed the bottom of the pond. 2 grains per pond (only after seedlings are kept) 1), covered with adequate maturity farmyard fertilizer from the mouth of about 5cm, irrigated with water, spraying 50% carbendazim 500 times, 2.5% enemy killed 2000 to 3000 times liquid. Cover with plastic film. After emergence to 3 to 4 true leaves, the local breaks the membrane and releases the seedlings after breaking the snow, and compacts the membrane breakage with fine soil. 2 The cultivator manages the timely removal of weeds, senescent leaves and dead plants.

First, nursery
1, selected fine varieties
2,5 lifting preparation. Around 7d before transplanting, topdressing was performed once per 100kg of water plus 0.2kg of urea. The seedling bed was poured on the night before raising.
Second, Daejeon preparation
1. Daejeon organizes deep-cultivation and maintenance work to keep the fields clean and timely remove the stubble leaves left after harvesting the former crops. Generally, per acre, apply 2500kg of good-quality manure fertilizer, mix 40kg compound fertilizer and 50kg of superphosphate, spread the fertilizer evenly on the ground, plunge deep into 30cm, and rinse the soil to open the soil.

Fourth, field management
1 Water and Fertilizer Management Principles of Water and Fertilizer Management: Look at the sky to see the seedlings quietly, cloudy days do not apply sunny, many times less drenched on the line. Zucchini more resistant to water, fertilizer, after transplanting survived, sunny forced dredge water, or 0.25kg urea per 100kg water, 2-3 scoops per pond; early flushing with slightly higher concentration of cleansing water, or per 100kg Water plus 0.5kg urea, 2-3 scoops per pond; when the flower is full, look at the weather and the growing conditions of the plants to water and fertilize more to ensure the normal growth of the plants and the need for fruit enlargement. Apply 40kg of urea per mu, generally with water 2 times.
V. Pest Control
According to the principle of "prevention first, comprehensive prevention and control", the principles of pollution-free governance of "agricultural control, physical control, and biological control" are adhered to. The main diseases of squash are: powdery mildew, downy mildew, anthracnose, etc. The pests mainly include: aphids and whitefly. The prevention and control of pests and diseases mainly based on disease-resistant varieties and the cultivation of disease-free strong seedlings, pay attention to ventilation and light transmission within the facility and the field, reduce air humidity, strengthen water and fertilizer management, combine biological control and rational use of high efficiency, low toxicity, low residue pesticides technology. Can be 75% chlorothalonil WP 500-600 times spray, 25% triadimefon 2000 to 3000 times spray for pest control. At the same time, we should take measures to avoid double weighting, and rotate with spinach, leeks, and cabbage. Can reduce pests and diseases.
Six, timely harvest
The zucchini is mainly eaten with tender melon, and it blooms 10 to 12 days after flowering. When root melon reaches 250g, it will be harvested. Harvesting too late will affect the growth of the second melon, and sometimes it will cause melon. Plants that grow vigorously tend to keep more melons and leave large melons. Appropriate plants harvest the melons later. Weak growing plants should keep melons and melons early. Take care not to damage the main vine when picking, and try to stay on the main vine as much as possible.
