1 Cultivation of strong seedlings: suitable for open field cultivation of a variety of monkeys, Atai, Huaye zucchini, long vine zucchini, gray pickled and so on. The main root of zucchini grows fast, and the root regeneration ability is poor after root cutting. Therefore, it is mainly based on live broadcast, and it can also be used to raise seedlings early. The open field broadcast period is late, and the benefits are poor; the cultivation of seedlings in the protected area can be mentioned in the morning market with good benefits. In actual production, it is still mostly based on seedling transplanting.
Before sowing, first select the water with water, remove the sputum floating on the water surface, soak it in warm water at 55 °C for 15 minutes, and continue to stir, then cool the water to 30 ° C, soak for 4 to 6 hours, remove the water control, and then use Soak the seeds with 1% potassium permanganate solution for 20 to 30 minutes or soak for 15 minutes with 10% trisodium phosphate solution. After soaking and sterilizing, remove it and dry it to a semi-dry condition. Wrap it in a wet gauze and place it at 25~30 °C to germination. After germination, it can be sown.
The nutrient soil for sowing is prepared 20 to 30 days before sowing.
Nutritional soil preparation method: It is prepared by using disease-free fertile soil and high-quality farmyard manure without melon seeds. That is, 6 parts of garden soil, 4 parts of decomposed horse manure or circle fertilizer, 0.1-1.0 kg of superphosphate and 5-10 kg of plant ash per cubic meter of nutrient soil, sifting garden soil and manure, mixing and packing (shopping) Go to the nutrient bowl or seedbed, pour water, and then sow.
Suitable seedling age for zucchini is 35 to 45 days. The seedlings are required to be thick and stalks, the internodes are short, the petioles are short, the leaves are thick green and thick, with four true leaves, the plant type is compact and the roots are developed. Seeding is too early, the seedlings are too large, the petiole, leaves and roots are susceptible to damage when planting; the sowing is too late, the seedlings are small when planting, and the maturity period is delayed.
2 heavy application of base fertilizer, timely planting: fertilize the soil before planting. Applying 75,000 to 105,000 kilograms of high-quality decomposed organic fertilizer per hectare, it is applied by a combination of application and ditch and acupoint application. Plowing and ploughing, squatting ridges and squatting, planting about 30,000 to 33,000 plants per hectare.
3 skill application of top dressing: about 1 week after planting, it is necessary to timely spray the seedling water, and combine with watering to chase 1 time to promote seedling fertilizer, apply about 2000 kilograms of decomposed cake fertilizer dilution per hectare to promote seedling growth, for many knots, Make a good foundation. After watering and fertilizing, the soil should be ploughed in time to increase the ground temperature. After slow seedlings, ditch can be applied to 3000 kg of decomposed cake fat or diluted manure and urine, and 750 kg/ha of ternary compound fertilizer can also be applied. After the cucurbits are closed, 15,000 to 22,500 kilograms of decomposed thin manure or cake fertilizer is applied per hectare during the period of cascading. Topdressing 3 to 4 times. In addition to paying attention to the management of fertilizer and water, it is also necessary to artificially pollinate and remove the first young melon in time, which can be used in the morning market, and can extend the result period to prevent premature aging and increase production.
Before sowing, first select the water with water, remove the sputum floating on the water surface, soak it in warm water at 55 °C for 15 minutes, and continue to stir, then cool the water to 30 ° C, soak for 4 to 6 hours, remove the water control, and then use Soak the seeds with 1% potassium permanganate solution for 20 to 30 minutes or soak for 15 minutes with 10% trisodium phosphate solution.
