High yield cultivation techniques
I. Variety selection
Select varieties with strong disease resistance, storage and transportation, dense meat quality, excellent quality, and high yield, such as Jiangdi 486, Jiangxin 4, Guanxing 2 and Jiangxin zucchini.
Second, planting seedlings
The use of nutrient cup nursery, nutrient soil selection of organic matter, nutrient rich, well ventilated soil. For every 1000kg of nutritious soil, use 50% carbendazim WP 25-30g in water to spray, mix well after spraying, cover the membrane, remove the membrane after 2-3 days, and disperse the drug gas into the nutrition cup. . When filling the cups, the side is filled with pressure, so that the nutrients in the cup are loosened tightly, and then they are drained neatly and flush on the flat seedlings. At the same time, the gap between the cups is filled with nutritious soil, and the filling of the earth is also noted.
Chayote seeds generally germinate irregularly, sowing seeds should be soaked before sowing to facilitate emergence of seedlings. Treatment method: Put the seeds into the temperature water of 52-55°C, stir constantly, after 15 minutes, soak in warm water of about 30°C for 3-4 hours, take out the seeds, drain them, wrap them in wet cloth, and put them around 30°C. Germination under conditions. During the germination period, the seeds are washed once a day. After 2-3 days, budding can be successively carried out. When the buds grow to 0.5-1.0 cm, they can be sowed. Pouring water in the nutrition cup before sowing, sowing 2-3 germinated seeds per cup, covering 1 cm thick nutritious soil, then covering a small amount of straw, and then watering. Seedlings can be transplanted when they are 20-25 days old.
Third, timely planting
After the late rice was harvested, it was ploughed and the fields were smashed and smashed. The sorghum was 30 cm high and 160 cm wide (including ditch). In combination with site preparation for basal fertilization, 30,000 kg of farmyard manure, 750 kg of cooked cake, and 750 kg of superphosphate are generally applied per hectare. About 2,000 colonies were planted per acre, and two rows per plant were planted with 35-40 cm spacing.
Fourth, field management
The melon plants grow to 5-7 knots later, using a bamboo skewer to take a "herringbone" and bringing the vines to the shelves. Immediately before the results, all lateral vines were removed and the results of the main vine were ensured. Later, 1-2 lateral vines above the middle of the plant were selected.
After three true leaves, apply 10% of farm organic liquid fertilizer every 7-10 days. When fertilizing, pay attention to fertilizer and water without sticking to seedlings. Before the scaffolding combined with heavy earth fertilizer, 600 kg of cake fertilizer per hectare, 375 kg of compound fertilizer and 150 kg of urea. Two heavy fertilizers were applied before and after the first harvest, and the amount of fertilizer was the same as the first time. The fertilizer is applied once every 6-8 days, and 225 kg of compound fertilizer, 75 kg of urea, and 150 kg of potash are applied per hectare. The top dressing method is to mix the fertilizer and apply it between the strain and the plant, then cover the soil.
Feast of melons and kibbles is fearful, and less water is required before pumping vines in winter and spring.
V. Pest control
Diseases of zucchini mainly include epidemics and anthrax. 58% of dandrug Mn-Zn wettable powder, 500% liquid of 64% anti-disease wettable powder, or 600% liquid of 90% diethylaluminophosphate wettable powder; Zinc wettable powder 800-1000 times, or 70% thiophanate-methyl wettable powder 800 times for control. Insect pests include thrips, aphids, tobacco budworms, and Liriomyza sativae. Can be used 5% of the WP 1500 times, or 10% imidacloprid WP 3000 times.
