Iron leeks cultivation technology
Iron leeks, alias blood see æ„, sea 蚌 rosary beads, leaves in the Tibetan beads. For the aerial part of the Acalyphaaustralis L. Cut in summer and autumn, remove impurities and dry. Habitat distribution: Born on hillsides, ditchsides, roadsides, fields. The distribution is almost all over the country, and the Yangtze River is especially exposed. Indications: clearing away heat and detoxification, dampness, convergence and stop bleeding. For enteritis, dysentery, vomiting blood, blood stasis, blood in the stool, blood in the urine, uterine bleeding; external treatment of hemorrhoids, dermatitis and eczema. Biological characteristics Hi warm and humid climate. Afraid of drought. It is advisable to plant in the sun and the fertile soil of the soil. The leeks can be cultivated from spring to autumn, and cultivated in the spring with suitable temperature and long sunshine. The convulsion is late, the quality is tender, and the yield is high. According to market demand, it can also be cultivated in protected areas to achieve annual production. Site preparation Iron amaranth is not strict with soil requirements, but it grows well with alkaline soil; it has a certain ability to resist drought, and it grows poorly in poorly drained fields. Should choose flat terrain, convenient irrigation and drainage, plots with few weeds, do the flat. The seeds of the iron leeks are small, so the soil must be fine when it is finished, so that the ground is flat and the soil is fine to facilitate the emergence of seedlings. Because the iron leeks are fertile, it is necessary to apply 1500 kg of manure and urination per 667 m2 before the preparation of the ground, and then do ridge or hoe. The seeding rate varies with the sowing date. The earlier the sowing date, the more seeding is used, the early spring seeding rate is 4-5kg/667m2, and the seeding method can be spread or broadcast. Cover soil 0.5-1cm after sowing. Topdressing and watering When planting in early spring, the seedlings are late, and it takes 7-12 days to emerge. When the seedling grows to 2 true leaves, the first top dressing can be carried out in the 3-5 leaf stage, and the urea is 10 kg per 667 m2; the second top dressing is carried out after 12 days, and the third top dressing is carried out after the first harvest, after Each harvest is 1 time, chasing 1 time fat, and each time the top dressing is applied with a thin liquid fertilizer mainly based on nitrogen fertilizer. If quick-acting nitrogen fertilizer is applied, it can be combined with watering. Spring sowing should be less watered. Cultivating, pruning During the growth of the seedlings, weeding and weeding should be carried out in time to prevent the grass vine from affecting the growth of the sorghum seedlings. The iron leeks are harvested many times, that is, after the main branches are harvested, 2-3 knots can be left at the base of the main branch to promote the germination of the side branches to achieve the effect of increasing yield. Pest Control Amaranthus has strong disease resistance, and the main disease is white rust. It can be controlled by powder rust or daisen zinc. Insect pests are aphids, which can be treated with imidacloprid or by spraying with mist. Harvest Iron leeks are leafy vegetables that are sown and harvested in batches. The first harvest, combined with the seedlings. Generally, 40-45 days after sowing, when the seedling height is 10-12 cm, and there are 5-6 leaves, they are harvested successively. When harvesting, it is necessary to grasp the principle of keeping large and keeping small and keeping seedlings uniform to increase the output in the later period. Topdressing after harvesting. Iron leeks mainly feed on their young leaves, so harvesting should be timely, otherwise the fiber will increase and the quality will decrease. The yield of acres (667m2) can reach 1000-1500kg.
