Weinanxing quality technical requirements (a) species name. Arisaema erubescens (Wall.) Schott. (2) Site conditions. The altitude is 150m to 400m, and the soil is cinnamon soil, tidal brown soil sub-class, tidal soil of tidal soil, shallow black coal and deep black coal tidal soil, loess and sandy loess of tidal loess. The pH is 7 to 8, and the organic matter content is ≥1.2%. (3) Cultivation management. The tuber is dominant and the seed is the secondary. The tubers should be selected from the fresh tubers of the previous year. The seeds should be selected as the new seeds of the year, and the germination rate is 75%. 1. Tuber reproduction: (1) Planting: planted between Qingming and Guyu. It can also be planted in summer, and it will be finished at the latest before the summer. When planting, on the whole clam surface, open a ditch (or digging hole) with a line spacing of 20cm to 25cm and a depth of 5cm to 6cm, planting at a planting distance of 14cm to 16cm, covering the soil from 4cm to 5cm, when the sensation is insufficient, timely pouring after planting water. At the time, the second top dressing is carried out, and the amount of topdressing is the same as the first time; the third top dressing is carried out in late July, and the composting compost or manure is 30,000 kg/ha to 60,000 kg/ha; the fourth top dressing is carried out in late August. Urea 150 kg / ha to 300 kg / ha, cake fertilizer 750 kg / ha. (3) Irrigation: The soil water content requires 18% to 20%. When it is less than 18%, it should be irrigated in time. Do not water at noon or afternoon. (4) Drainage and cooling: Pay attention to drainage during the rainy season to prevent water accumulation in the field. If there is no rain in the sky, the weather is hot and the ventilation is poor, the management personnel can walk around the ridge in the afternoon to dissipate heat. (5) Picking the moss: When the spikes of the Minnan star meat are extracted from the sheath-like mites from June to August, they should be cut off in time to reduce the nutrient consumption. 2. Seed propagation: After 3 to 5 years of tuber propagation, in order to restore the seed, seed must be used for one year. The seed propagation is carried out by seedling transplanting, and the seedling raising time is carried out in the autumn of mid-September or in the spring of May of the next year. Dig shallow trenches with a line spacing of 14cm to 16cm, the depth of the ditch is 1.5cm, and the seeds are evenly sprinkled into the ditch, and the covering soil is 1.5cm flush with the kneading surface. After sowing, irrigate once and keep the soil moist. (1) Management of seedbed bed: In autumn, the seedlings are covered with composted compost or manure in winter, and the skin is warmed and moistened to facilitate the wintering of the seedlings. In the spring of the second year, compost or manure is pressed into the seedbed for fertilizer. In the autumn, the seedlings were not sparsely seeded. After the early spring of the second year, when the seedling height was about 3cm to 5cm, the thin and thin seedlings were too dense. (2) cultivating and weeding: weeding by hand or shallow hoeing, weeding and wetting, and then gradually deepening, the number depends on soil dryness and weed production, and can not damage the main root when loosening. (3) Fertilization: In the autumn, the fertilizer will not be fertilized, and the next year can be topdressed twice. The first time is carried out after thinning and cultivating, and the second time is carried out before transplanting. The first application of decomposed rare human excrement 15000 kg / ha, the second time can be increased to 22500 kg / ha to 30,000 kg / ha. Combined with the application of 225kg/ha of superphosphate and 75kg/ha of potassium chloride. (4) Irrigation and drainage: After sowing, the soil moisture content is required to be 20 to 22%, and the surface of the seedlings is kept moist before being released. The seedlings of autumn sowing can be watered for 1 time before wintering, and can be timely watered with the topdressing after spring, and the water should be kept in sufficient water. In case of rainy season, water in the field should be drained in time. (5) Transplanting: When the seedling height is 6cm to 9cm, choose cloudy days, and grow robust seedlings, with a little soil, transplanted in Daejeon according to row and plant spacing of 20×15cm. 3. Shading: The negative plants of the southern genus are afraid of strong light. After planting, corn or other high-stalk crops should be placed on the rafts at a distance of 30 cm for the shade of the southern star. (4) Harvesting and processing. The tuber is harvested in the same year, and the seed is harvested 2 to 3 years later. The harvest period is from late September to early October. Choose a sunny day to dig up the tubers, place them in flowing clear water, and wash them with a large bamboo broom repeatedly to wash the impurities. If the tuber is not cleaned, the outer skin can be scraped with a bamboo knife. The peeled tubers are exposed to sunlight (or fire) to a moisture content of 11% to 13%.
