High-yielding cultivation techniques of southern melon

1. Variety selection

Choose varieties with strong disease resistance, storage and transportation resistance, dense meat quality, high quality and high yield, such as Jiangdi 486, Jiangxin No. 4, Guanxing No. 2, Jiangxin Zucchini, etc.

Second, sowing and raising seedlings

A nutrient cup is used to raise seedlings, and the nutrient soil is selected to be soil with more organic matter, rich nutrients, and good aeration. Spray 25-30 grams of 50% carbendazim wettable powder per 1000 kilograms of nutritious soil in water for spraying, mix well after spraying, cover the film, peel off the film after 2 to 3 days, and disperse the medicine gas into the nutrition cup . Fill and press while filling the cup, so that the nutrient soil in the cup is loose and tight, and then discharged neatly and tightly on the flat seedling border, and at the same time fill the gap between the cups with nutrient soil, pay attention to the border side also need to fill the soil.

Zucchini seeds generally germinate unevenly, soak seeds and germinate before sowing to facilitate emergence. Treatment method: Put the seeds in 52-55°C water and stir continuously. After 15 minutes, soak them in warm water at about 30°C for 3-4 hours. Take out the seeds and drain them, wrap them with a damp cloth and place them at about 30°C. Germination under conditions. The seeds are washed once a day during the germination period, and the buds can be sprouted successively after 2-3 days. When the buds grow to 0.5-1.0 cm, they can be sown. Pour enough water into the nutrient cup before sowing, sow 2 to 3 germinated seeds per cup, cover 1 cm thick nutrient soil, then cover a small amount of straw, and then water. It can be transplanted when the seedling age is 20-25 days.

3. Timely colonization

After the late rice is harvested, it is ploughed and dried in the field. The rake is flattened and broken up, and the border is 30 cm high and 160 cm wide (including ditch). Combined with the application of sufficient base fertilizer for site preparation, generally 30,000 kg of rot farm manure, 750 kg of rot cake fertilizer and 750 kg of superphosphate are applied per hectare. Approximately 2000 plants are planted per mu, each row is planted in two rows, and the plant spacing is 35-40 cm.

4. Field management

When the melon plant grows to 5-7 knots, use a small bamboo pole to set up a "herringbone frame" and lead it to the shelf. Before the results, all side vines should be removed in time to ensure the results of the main vine, and then 1-2 side vines above the middle of the plant should be selected.

After the three true leaves stage, 10% of the farm's organic liquid fertilizer is poured every 7-10 days, pay attention to the fertilizer and water not to stick the seedlings when fertilizing. Before putting up the frame, apply heavy soil to apply heavy fertilizer, apply 600 kg of cake fertilizer per hectare, 375 kg of ternary compound fertilizer, and 150 kg of urea. Two heavy fertilizers were applied before and after the first fruit harvest, and the amount of fertilizer application was the same as the first. In the future, top dressing every 6-8 days, applying 225 kg of ternary compound fertilizer, 75 kg of urea, and 150 kg of potassium fertilizer per hectare. The top dressing method is to mix the fertilizer evenly and apply the hole between the plants, then cover the soil.

Zucchini likes to be wet and afraid of waterlogging, and needs less water before pumping in winter and spring.

5. Pest control

The diseases of zucchini mainly include blight and anthracnose. The epidemic disease is controlled by 58% of the poisonous mildew manganese zinc wettable powder 500 times, or 64% of the poisonous alum wettable powder 500 times, or the 90% ethyl phosphorus aluminum wettable powder 600 times; 80% Daisen is used for anthracnose 800-1000 times of zinc wettable powder, or 800 times of 70% thiophanate-methyl wettable powder for prevention and control. Insect pests mainly include thrips, aphids, tobacco worms, and Liriomyza sativae. It can be controlled with 5% of thistle aphid net wettable powder 1500 times, or 10% imidacloprid wettable powder 3000 times.
