Achyranthes is one of the 63 kinds of indiscriminate Chinese herbal medicines recommended by the State Administration of Pharmacy in recent years. With the new discovery of the medicinal value of Achyranthes bidentata, the amount of Achyranthes bidentata is increasing, and wild resources can no longer meet the needs of the market, and it is urgent to be cultivated artificially. At present, the price of Achyranthes bidentata in major pharmaceutical cities nationwide rises, and the market outlook is promising. Conditional farmers and farmers can develop plants according to local conditions. Achyranthes is a medicinal plant species with low investment and quick effect, and is calculated based on the current market purchase price. In 3500 ~ 4000 yuan. Now the high-yield cultivation points are described as follows: site preparation and site preparation. The main root of Achyranthes is long, and it is better to choose the sandy loam with deep soil, loose fertility and well-drained soil. After the harvest, deepen the soil, use 250,000 kg of decomposed manure, 50 kg of superphosphate and 20 kg of rapeseed cake per acre. Mix evenly in the topsoil, then plow it once and turn it into the soil as base fertilizer. Before the sowing, the land was leveled and made fine. The width was 1.3 meters high, and the furrows were 30 centimeters long. A deeper drain was made around.
sowing. Achyranthes can be planted in spring and summer, and the best sowing period is from the late May to the early July in the south of the Yangtze River basin and the south. Before sowing, the seeds are soaked in warm water at 20°C for 3 to 4 hours. After they are picked up for drying, they are mixed evenly with the fire and earth ash, human and animal waste water, and sown on the surface. After sowing, the soil is gently raked with four-tooth rakes. Face, so that the seed sinks into the soil, and then spread a layer of fine soil, about 1 to 1.5 cm thick, can also be drilled, in the pod surface spacing 26 to 30 cm open shallow ditch, and then evenly spread the seeds in the ditch , Cover with a layer of fine soil to cover no seeds. Finally, a thin layer of chaff or rice straw is spread over the surface to facilitate emergence.
Field management.
1. Keep seedlings between seedlings and seedlings: After sowing, the field should maintain a certain humidity, and the seedlings can emerge in 4 to 5 days. The seedlings grow weakly in the early stage. In case of dry weather, water should be kept in time to protect the seedlings. When the seedling height is 5 to 7 cm, the first time the seedlings are started, weak and strong, keep the seedling distance 6 to 7 cm, when the seedling height is 15 to 17 cm, the seedlings are to be planted at 1515 cm spacing. If there is a lack of seedlings, a cloudy day can be used to make up the seedlings.
2, weeding and weeding: after Qimiao, we must timely weeding, and follow the application of thin human and animal waste water mixed fire ash, per acre 1000 kg applicator; Dingmian, combined with cultivator weeding, application of human and animal manure water mixed soil Mixed fertilizer of mixed fertilizer, 1500 kilograms per acre, in the period of strong growth from August to September in the inter-row ditching into the 2000 kg of livestock and manure water plus 50 kg of superphosphate, cover fertilizer after application.
3. Picking flower buds: When the height of Achyanthes rose is about 50 cm, the top inflorescences are removed in batches in time so that the nutrients are concentrated in the roots.
4, drainage irrigation: seedling period to early August, should control the water to promote the main root bar, conducive to root growth; after August, the main root is no longer stretched, the amount of irrigation can be larger to promote the development of thick roots. After the rainy season and heavy rain, pay attention to drainage in time.
Pest Control. The main diseases are leaf spot and root rot. Leaf spot occurs mostly during the rainy season. When the disease occurs, yellow or brown spots appear on the diseased leaves. In severe cases, the leaves become gray-brown and the plants die. Prevention methods: 1 Drain the gutters in time to reduce the humidity in the fields and maintain the ventilation and light transmission. To enhance plant resistance to disease; 2 after onset, spray 1:1: 100 Bordeaux mixture, or 65% 500% Zeixin zinc, once every 7 days, and even spray 3 to 4 times. Root rot is easy to occur after standing water in the planting area. When the disease occurs, the roots become brown, water-stained, rot gradually, and the stems and leaves on the ground die. Control methods: 1 timely drainage and drainage. 2 Onset of disease, use 50% carbendazim 1000 times or 5% lime milk gorilla. The main insect pest is nematode disease, which causes the roots to produce nematodes, and loses the ability to transport nutrients, affecting the yield and medicinal quality. Control methods: 1 rotation, the best dry and dry rotation; 2 soil disinfection in the preparation of the implementation, can be applied per acre 3% methyl isothiophos 5 kg, sprinkled in the surface, into the soil.
Harvest processing.
1. Harvest: Achyranthes can be harvested 6 to 7 months after sowing, generally during the fall of autumn and winter when the stems and leaves are yellow. When digging, all the whole roots of Achyranthes are to be taken out and roots should not be cut.
2, processing: first dig the root bar shake off the sediment, remove hairs, lateral roots, and then straighten the root bar, tie into 10 each, on the outdoor drying, drying to 80% dry, retrieve the heap Cover the straw mat to make it "sweat," and then take it out to dry after two days.
sowing. Achyranthes can be planted in spring and summer, and the best sowing period is from the late May to the early July in the south of the Yangtze River basin and the south. Before sowing, the seeds are soaked in warm water at 20°C for 3 to 4 hours. After they are picked up for drying, they are mixed evenly with the fire and earth ash, human and animal waste water, and sown on the surface.
