Techniques for planting zucchini in open field: Planting zucchini should first choose a variety with high growth potential, high fruit setting rate and good quality, especially for disease resistance. The suitable sowing date of autumn zucchini is mid-to-late July, the row spacing is 1m, and the plant spacing is about 40cm. In the management of water and fertilizer, before the seedling stage to the flowering and fruit setting, the main purpose is to keep water and control the water and control the fertilizer, to prevent the occurrence of excessive water or excessive water and the “scarred†zucchini as the main vine, mainly in the zucchini. The spraying of Huahua No. 3 promoted the reflux of nutrients in the top of the plant, inhibited the growth of the main shoots, transformed the growth nutrients into reproductive nutrients, and promoted flower bud differentiation to improve the quality of flower bud fertilization. Cultivar of zucchini Scientific field management Zucchini greenhouse cultivation technology 1. Soil preparation and fertilization It is mainly based on organic fertilizer. Generally, 2000 kg of organic fertilizer is applied per mu, 75 kg of cake fertilizer, 40 kg of compound fertilizer, and 80 kg of grass ash. Spread the fertilizer evenly on the ground, turn it 30 cm deep, and level the ground. 2, ditching and squatting It is covered with deep sorghum and covered with plastic film. Generally, the width is 100 cm, the height is 20 cm, and the width is 25-30 cm. The surface of the dough should be leveled again before the film is covered, and the herbicide should be sprayed. When covering the film, it must be tightened and flattened so that the mulch film and the enamel cover are closely attached, and the periphery of the film is compacted with soil. After soil preparation and fertilization as a cover film, use 45% of the bacteriostatic agent for 1 kg of smoke per acre before planting, and close the greenhouse for 7 days. 3, colonization It is usually planted in mid-March. When the seedlings are in the 3rd leaf or 1 leaf, the seedling age is about 30 days. Small varieties are planted in rows of 40×40 cm, with about 1800 plants per mu. Large-scale varieties are planted in rows of 50×50 cm, with about 1600 plants per mu. 1 day before planting, the seedbed is watered, the seedlings and seedlings are selected, and the roots are transplanted as much as possible. When the planting is done, the roots should be stretched normally. After planting, the root water should be poured, and the planting holes should be tightly covered with fine soil. After that, water is poured once a day until the seedlings survive. 4, temperature The seedling stage is not ventilated, the shed temperature is increased, and the roots are promoted. The shed temperature should be maintained at 25-28 °C during the day and 18-20 °C during the night. When the shed temperature exceeds 30 °C at noon on sunny days, it can be properly ventilated. After the slow seedling, the shed temperature is controlled at 20-25 °C during the day and 12-15 °C during the night, which is beneficial to the differentiation of female flowers and early sitting. After sitting on the melon, keep the temperature to 22-26 °C during the day, 15-18 °C at night, and the minimum is not lower than 10 °C. Increase the temperature difference between day and night, which is conducive to nutrient accumulation and melon expansion.
