How to grow Achyranthes bidentata? What are the diseases and insect pests to be controlled? Please introduce and guide the cultivation methods of Achyranthes bidentata and the following methods for diseases and insect pests: land preparation is a deep-rooted crop, and it is appropriate to choose sandy soil with deep soil layer, loose and fertile soil, good drainage and low groundwater level. After selecting a good land, it is necessary to turn the land deeply, ploughing at a depth of about 40 cm, ploughing and raking many times, finishing fine soil, and applying sufficient bottom fertilizer. The compound fertilizer of potassium sulfate type is 40ml / mu and 80kg. After leveling and raking fine, make a high border with a width of 1.3 meters, with a ditch of 40 centimeters, with a deep drainage ditch around it, to be sown. Sowing method and time: sowing time, Sichuan had better sow in early April, Shandong around July 15, Beijing in early June, Henan in early July, using strip sowing, the row spacing is 15-20 cm, the ditch depth is 2-3 cm, the thickness of soil cover is about 1.5 cm, it is flat after sowing, generally 7-color seedlings emerge in 10 days, and the sowing amount per mu is 2-2.5 kg. Field management: (1) seedling, fixed seedling: seedling height 7 cm time seedling, seedling height 17-20 cm according to plant spacing 15 cm seedling. (2) Intermediate ploughing and weeding: 2-3 times before and after seedling setting, and shallow hoeing to loosen the soil to cut off the fine roots in the topsoil, which is beneficial to the growth of the main roots. (3) topdressing: generally, after the seedling is fixed, from late July to August, depending on the seedling situation, rarefied human feces and urine should be applied once, and if the base fertilizer is sufficient, it may not be applied. (4) drainage: except for the need to keep the soil moist in the seedling stage, it is generally not suitable to water more in the future to prevent the overgrowth of the aboveground parts. Stagnant water should be removed in time during the rainy season. (5) topping: the top buds are cut off in time when budding, usually 2-3 times, and the plant height is controlled at about 45 cm. Disease control: root rot harms the roots, making the roots turn brown, show water stains, gradually rot, and the aboveground stems and leaves gradually die. Control methods: (1) reduce the humidity in the field and pay attention to ditch drainage; (2) when the disease occurs, use 1000 times of carbendazim or 5% lime milk. Nematode disease harms the root, causes the root to produce nodular galls, loses the function of dredging nutrients, and affects the yield and the quality of medicinal materials. Prevention and control methods: (1) rotation, preferably flood-drought rotation; (2) soil disinfection during soil preparation: 5 kg of 3% methyl isosphos per mu, sprinkled on the border surface and turned into the soil. The inchworm bites the leaves, which is camouflage and fake death. Prevention and control methods: (1) artificial killing by using false death; (2) spraying and killing with 1000 times of trichlorfon. Red spiders and stink bugs occur from May to June, harming young shoots and leaves. Prevention and control method: spray with 1000 times of dimethoate. Achyranthes bidentata can be harvested three years after sowing, and the harvest period is between the end of October and November. After digging, shake off the soil, cut off the Reed head, cut off the fibrous root, tie it into a small handful, and put it on the Kang or on the sun field. In the drying process, we need to pay attention to the firepower should not be too large, in order to avoid oil. After semi-dry, pile up for 7-10 days, moisturize, and then Kang or sun to fully dry to become commercial medicinal materials. The specific yield per mu of planted achyranthes bidentata depends on the quality of management. Under normal circumstances, the output of dry goods per mu of three-year-old achyranthes bidentata can reach 150-200 kg, and that of four-year-old can reach 200-250 kg.
