Zucchini grows and develops normally at temperatures between 15 and 20°C. The brewing hotbed is selected for production in large (middle) sheds to facilitate thermal insulation. The average bed width is 1.2 meters, depth is 0.6-0.7 meters, the straw is crushed into 6-9 centimeters, soaked with water for 2 to 3 days, then drained and drained, and a small amount of lime mixed with human feces is mixed and fermented for 2 to 3 days. In the excavated bed, the thickness of the brewing layer should be 30-40 cm. Use 70% vegetable garden soil, 30% soil miscellaneous fertilizer plus 0.5% potassium dihydrogen phosphate, mix well, pour the waste water and pour it for 1 week. Use 16cm 10cm nutritious soil with 0.5 kg nutrient soil or make a big goose egg ball. , neatly arranged in a hotbed for use.
The selected seeds are soaked in warm water of 55-60° C. for 15-20 minutes, then soaked in fresh water for 5-6 hours, and then germinated at a temperature of 25-30° C. Each nutrient bag was broadcasted with 1 bud seed, and 1 cm of fine soil after sowing. The nutrient bag gap was filled with nutrient soil and watered. A small arch shed (arch height of 0.34 to 0.5 cm) was kept warm. Pay attention to the management of bed temperature during nursery. After emergence, ventilation should be promptly conducted to reduce the temperature inside the bed and avoid the formation of tall seedlings. 5 to 7 days before planting, the greenhouses will be uncovered between 10 am and 15 pm in sunny weather.
Before planting, the soil with high organic matter content, strong water retention and fertility, and deep clay soil as the planting site were selected. After the harvest of the previous crop, timely excavation of earthworms, 1 meter open after sub-fine leveling, car width 70 to 80 centimeters, compartment height 20 to 25 centimeters, each line, row spacing 40 centimeters, Wo outsole deep. Mu with composted soil and fertilizer 2500 kilograms of foliar cover soil 5 to 7 cm back. One week before planting, cover the membrane on the surface of the car. The soil around the membrane is tight to increase the soil temperature. Seedlings grow to 2 leaves and 1 heart at a fixed value. Using a knife to draw a thin film at the nesting site, choose a robust, disease-free seedling with soil and colonize the nest. Pulverize the soil, fix the roots, pour the manure, set the roots, cover the holes with fine earth, and plant the holes. Immediately afterwards, a small shed was stamped and the arch height was 50 cm. The arch was tightly insulated with earth pressure. During the frost period, frost protection was added to the sheds at night.
After planting and survival, 1000ppm ethephon solution was sprayed to promote female flower differentiation. When the plant grows to 5 leaves, the fruit begins to sprout. Because of the early low temperatures, the plants grow in the shed. Insects pollinating female flowers should be isolated and artificial pollination should be conducted. When the early female flowers are abundantly produced, the temperature is low, and the male flower pollen and insects are less active. In addition to timely pollination for artificial pollination, 30-50 ppm of anti-dropping hormone or 2.4-D female stigma is also needed to preserve the melon. When the temperature is stable above 20°C, the arch membranes will be removed in time to facilitate good photosynthesis and insect pollination. Zucchini before the melon, the early plant nutrition area is small. The melons growing to about 0.5 kg should be harvested and marketed in time. At the same time, compound fertilizers, foliar treasures, or nitrogen, phosphorus, and potassium should be top-dressed in order to provide sufficient nutrients for the formation and growth of melons and improve the development of melons. rate. A large number of young melons are formed at the stage and potassium dihydrogen phosphate is sprayed on the leaves to supplement the large amount of melon to form the necessary nutrients. Pests and diseases are a major factor affecting the quality of summer squash products. During the whole period of growth, comprehensive prevention and control should be carried out. The main diseases of summer squash are downy mildew, powdery mildew, anthrax, etc., which are treated with 500 to 800 times of R. utilis or thiophanate and carbendazim at 800 to 1000 times; the main pests are yellow squash, aphids, and other trichlorfons. 800 to 1000 times liquid prevention.

Variety selection leaves three squash. The species is characterized by strong cold tolerance, short internodes, and dense melons. Generally, the melons are started in the fifth quarter, and each melon can be harvested with 6-7 melons per plant. The average melon weight is 0.5-0.75 kg. Producing tender melons above 5000 kg.
