Virus-free sweet potato cultivation techniques

The detoxification of sweet potato has the characteristics of high yield, good quality, strong resistance, and high yield. Generally, it increases production by about 30% per mu, and can reach over 40% by high. 1, use fine varieties. Such as: victory 100, Xushu 18, Japan Red East virus or seed. 2. Establish a nursery and cultivate strong seedlings. One is Miao Miao: The use of dense planting method fertilization super ridge, ridge distance 50-60 cm, spacing 10-13 cm, planting 10,000 per acre, can be planted into the nursery before and after the rain, planting potato seedlings available ABT rooting Soak the seedlings with the agent to promote early-onset roots. At the same time, it uses greenhouses, small sheds, mulch, etc. to heat and moisturize. The nursery should increase fertilizer and water management, apply 4000-5000 kg of compost per acre, 20-25 kg of ammonium bicarbonate, and 30-40 kg of superphosphate. After the seedlings are cut, the seedlings are planted again until they are finished. The second is the breeding of virus-free seed potatoes: the use of electric heating hotbeds, brewing hotbeds, solar greenhouses, plastic greenhouses and other methods of raising temperature seedlings, the simplest method can use high fertility vegetable garden for seedbeds, used sieved Pig cage dung, soil dung, grass and wood ash and other fully mixed with the bed soil, a thickness of 10 cm, loose bed soil, leveling the bed surface, conducive to heat aerobic bacteria, seedlings will use 25% of the carbendazim plant seed 1000 times Soaked in liquid for 10 minutes, the potato head upwards obliquely, the head facing south, the head pressing the tail 1/3, the potato block Yang surface upward, the large and small potatoes separated, the upper Qi Qixia, 20-25 kg per square meter row species The gap between the potatoes is to leave a gap, fill in the soil, fill with water, cover the nutrient soil with a thickness of 2-3 cm, insert the bow and cover the membrane, heat and moisturize, and promote germination. 3-5 days after seeding, high temperature germination, temperature 35-37 degrees, but not more than 40 degrees, then down to 30 degrees, rapid seedlings, 20-25 degrees after seedlings, low temperature hardening seedlings, about 7 days Budding. Appeared in about 20 days, when the potato seedlings 5-7 leaves when the cut seedlings, planted into the nursery, resolutely do not pull seedlings. Every time you pick a seedling, you need to chase the right amount of urea or mature manure urine. 3. Reapply base fertilizer. Sweet potato is a crop that requires more phosphorus and potassium. In high-yield cultivation, 2000-3000 kg of earth-fertilizer per acre, 100-150 kg of plant ash, and 50-100 kg of superphosphate; in the case of poor production conditions and low soil fertility, bicarbonate can be applied per acre. Ammonium 10-25 kg. 4, timely planting. Chunshu is usually planted to small full-grown (earth temperature up to 18 degrees can be planted), summer potato is generally planted in the summer solstice. 5, rational close planting. The sweet potato field requires deep ridges, water retention and fertilizer, loose ventilation, and live soil thickening in favor of tubers. High ridge standard: ridge height 40 cm, top width 40 cm, ridge distance 1.2 meters; general planting density of spring sweet potato maintained at 3,500 per acre, summer sweet potato 4000 per acre. 6, field management. One is to open a good "three ditch", "four ditch" (ridge ditch, waist ditch, ditch ditch), so that drainage and irrigation flow, rain live to dry. The second is to prevent insects and disease. When ridging, 30 kg of an enemy powder is thrown into the soil to prevent underground pests; spray with 1000 times liquid of 90% crystal trichlorfon can prevent all kinds of insect pests; use carbendazim to soak seedlings. , can prevent black spot. The third is the spraying of paclobutrazol on the Wangchang block, which suppresses the growth of stems and leaves and promotes the expansion of the potato block. The fourth is weeding and weeding. About 30 days after the planting of sweet potato, the cultivator timely weeded and weeded the soil and cultivated the soil to create a good environment for the growth of the sweet potato. 7, timely harvest. Local seed potatoes are generally suitable for harvest in the middle or late October. They are required to be harvested and dried in the morning on sunny days, and enter the pit in the afternoon of the same day. When entering the pit, sweet potatoes that do not meet the seed-keeping criteria are removed and stored in the cellar after being treated with carbendazim to ensure quality.
