Atractylodes macrocephala is a herbaceous plant of the herbaceous rhizomes of the Asteraceae family. Rhizomes are used as medicinal herbs and have functions such as strengthening spleen Qi, removing dampness, diuresis, preventing fetuses, and preventing sweating. Its nature likes warm and cool, can withstand low temperatures, high temperature, scorching, drought and waterlogging; not suitable for growth in saline and alkaline lands, viscous soils, and sandy soils. It should be suitable for fertile, deep, moist but not waterlogged, slightly acidic and alkaline soils on shady slopes and soils. Cultivated on sandy loam soil. White magic avoid continuous cropping, the former for the grass crop is better, new land can also be planted. It is not appropriate to rotate crops with other crops to prevent infection. Its high-yielding cultivation techniques are as follows. First, planting seedlings in early spring, 667 square meters of cooked manure fertilizer 2000 kg, 50 kg of cake fat, deep smashing after smashing. In the "clear bright" to "grass rain" between the wells to open a groove, the groove 25 cm, width 10 cm, 4 to 5 cm deep. The bottom of the ditch should be flat, and phosphorus calcium should be applied at the bottom of the ditch. Before sowing, the seeds are soaked in warm water at 25-30°C for 12 hours and then removed. The seeds are put in burlap bags and placed in a room at 25-30°C. Each morning and evening, 25°C-30°C warm water is used for showering. 4 to 5 days, the buds begin to germinate. To prevent the infection of bacteria, 50% thiophanate-methyl 1000 times solution can be used to soak for 5 minutes, and then sown after drying. After the fine seeds are uniformly spread, the seeds are covered with grass charcoal or fine charcoal ash, and the straw is kept warm, moisturized, and windproof. About 5 kilograms of seedlings (1 square meter for nursery and 7 square meters for planting in Daejeon) will be planted after about 8 to 10 days of emergence. After Miao Qi weed out in time. When the seedling height 7 cm, according to the seedling distance 4 to 6 cm set seedlings, and remove the thin and weak seedlings, and timely do a good job of trench drainage. In the sunny morning, when the exposed water of the leaf is dry, gently remove the loose soil with a small hoe. Apply diluted manure water once every 20 days or so, first light and then thick. In dry weather, timely irrigation is required. After the "frost," cut the stem roots, cut stems and leaves, fibrous roots, placed in a ventilated place for 3 to 5 days, until the skin is white and dry and ventilated place. After laying a 50-cm-high storage tank on the ground, a 5-cm-thick clean layer of river sand is laid on the ground and a 15-cm-thick rhizome is placed on the floor, but a straw is inserted in the middle to Ventilation ventilation. Then cover a layer of fine dry sand, put a layer of rhizomes, and finally cover a layer of 7 to 10 cm thick sand. The rhizome is called a transplant seedling. Second, plant management (1) planting. In mid-December of that year or the middle or late February of the following year, the shady slope was selected. After applying the base fertilizer and deep plowing, a 1.2-meter-wide sorghum was made, and planting holes were planted at a spacing of 2025 cm. Afterwards, choose a uniform size, full top buds, slender top, delicate skin, uniform size rhizome, put a surgery seedling per hole, top buds facing up. Then, the cover soil is compacted and filled. Use about 50 kg/667 square meters. When planting in winter, it is necessary to cover plastic film insulation to facilitate early germination and early emergence of seedlings, so that plants grow robustly. (2) Weeding and weeding. After emergence, dry soil after weeding in dry weather after rain. After the seedlings return to green, only one main stem is left and the sprouts are erased in time. In the middle of May, after the plant was closed, only the grass was not pulled loose. (3) Dressing. For the first time in early April, 667 square meters of cooked manure was diluted with 800 kilograms of water. The second time, in the second trimester, 667 square meters of planted manure water 1,000 kilograms. The third time was the period of underground rhizome enlargement. After the buds were removed in July and mid-July (leaving the crops without planting), 2000 kg of manure water was applied to 667 square meters, 100 kg of cooked cake fertilizer or 50 kg of ternary compound fertilizer. Third, pest control Atractylodes common diseases such as blight, blight, iron leaf disease, rust and so on. Prevention methods: 1 Drain the trenches in time during the rainy season so that no water accumulates after the rain, and loose soil and prevent soil compaction when it is fine. 2 Remove the diseased plants and disinfect the lime. 3 drug control. In the initial stage, 50% carbendazim or 50% thiophanate-methyl 1000 times solution is used to irrigate the ward, or a 1:1:1 Bordeaux mixture is sprayed once a week for 3 to 4 consecutive times. The main pests are Atractylodes lucidum, Longkong Long, small ground tiger, pupa and so on. In the initial stage, 50% of dichlorvos were used to spray the seed insects 800 times for 7 days and continued for 3 to 4 times. The tube was sprayed with a 40% dimethoate emulsion 1000 times. Small tigers and earthworms were hunted by watering roots or baits with 1000 times 75% sulfuric acid EC. Fourth, harvest processing In late October to mid-November, when the stem turns from green to yellow-brown, choose sunny cut stems, root excavation. The roots and stems of the excavation shall not be damaged or washed with water. After removing the fibrous roots, shaking off the soil, drying or drying the finished products. 667 square meters of dried products 800 to 1000 kg. China Agricultural Network Editor
