1 Cultivate strong seedlings: The fine varieties suitable for open cultivation include a litter of monkeys, ahta, mosaic zucchini, long vine squash, and gray cassia. The main root of zucchini grows fast, and the ability of root regeneration after root cutting is poor. The live harvesting period of the open field is late, and the efficiency is poor; the nursery cultivation in the protected area can be referred to the morning market and the benefit is good. Actual production is mostly based on seedling transplanting.
Before sowing, first select the seeds with clear water, remove the granules floating on the surface of the water, soak it in warm water of 55°C for 15 minutes, stir continuously, then cool the water to 30°C, soak for 4-6 hours, remove the water, and reuse The 1% potassium permanganate solution is soaked for 20-30 minutes or soaked with 10% sodium phosphate solution for 15 minutes. After soaking, disinfect the fish and remove them. When it is air-drying until it is half dry, wrap it in wet gauze and put it on the place at 25~30°C.
The soil for sowing is prepared 20-30 days before sowing.
Nutrition soil preparation method: Choose disease-free fertile soil and high-quality farmyard fertilizer that have not been planted with melon vegetables. That is, six soils for garden land, four for composted horse manure or ring fertilizer, 0.1 to 1.0 kg of superphosphate per cubic meter of nutrient soil, and 5 to 10 kg of plant ash, and the garden soil and manure will be sieved and mixed and distributed (shop) Into a nutrient bowl or bed, soaked with water, then sowing.
The suitable seedling age for summer squash is 35-45 days. The seedling stems are required to be stout, with short internodes and short petiole. The leaves are thick green and thick with 4 true leaves. The plant type is compact and the roots are well developed. Early sowing, too large seedlings, petioles, leaves, and roots are vulnerable to damage when planting; when sowing is too late, the seedlings are smaller when planted, and the maturity is delayed.
2 heavy base fertilizer, timely planting: fertilization before planting site preparation. Apply 75,000 to 105,000 kilograms of high-quality decomposed organic fertilizer per hectare, applying the method of application combined with ditch and hole application. Ploughing, ploughing and cultivating ridges, planting 30,000 to 33,000 plants per hectare.
3 clever application of fertilizer: about 1 week after planting, watering the seedlings in a timely manner, and combined with watering chase 1 time reminder Miaofei, apply about 2000 kg per hectare of cooked cake fat dilution, promote seedling growth, for more than melon, Big melons lay the foundation. After watering and fertilizing, the soil should be cultivated in time to increase the ground temperature. After easing the seedlings, it is possible to open a ditch with 3000 kg of decomposed cake fat or diluted feces and urine per hectare, and 750 kg/ha of ternary compound fertilizer. After guava ridge closure, 15,000 to 22,500 kilograms of decomposed diluted manure or cake fertilizer are applied along the hectares during the period of squashing. Top dressing 3 to 4 times. In addition to paying attention to fertilizer and water management, it is also timely to artificially pollinate and remove the first baby larvae. This can be used in the morning market and can extend the result period to prevent premature senescence and increase yield.
