Cultivation and harvesting of Achyranthes bidentata
The Achyranthes bidentata is one of the "four major remedies". The root can be used medicinally, and the raw product has the effect of loose blood stasis and clear phlegm. The symptoms include sore throat, high blood pressure, amenorrhea, no clothing, and bruises. Wine products complement liver and kidney, strong bones and bones, attending liver and kidney deficiency, waist and knee pain, limb weakness, rheumatism, etc. The site selection and preparation of deep root crops in the Achyderma plantation should be planted in sandy loam with deep soil, loose fertility, good drainage, and low groundwater level. After the previous harvest, deep-dip more than 60 cm, irrigation to make the surface soil sink. After slightly drying, apply 2500 kg of rotten manure, 50 kg of superphosphate, and 20 kg of rapeseed cake per acre. Mix it evenly before application, stack the crop evenly over the topsoil several days later, and then pour it into the soil as base fertilizer. After the leveling process is completed, a 1.3-meter-wide squat is made, and a deeper drain is created around. Sowing in the first half of July is suitable for planting. If the planting period is too early, the stems and leaves on the ground will grow faster, the flowering period will be earlier, the underground roots will have more gingivae, and the medicinal materials will be of poor quality; if they are too late, the growth of the plants will be poor and the yield will be reduced. Before sowing, the seeds shall be soaked in warm water at 20°C for 12 hours, picked up and dried, then mixed with fire-soil ash, human and animal waste water and evenly sown on the simmering surface. After sowing, the surface of the soil is gently shaken with a four-toothed rake, so that the seed is sunk into the soil, and a layer of fine soil is spread to cover about 1 to 1.5 cm in thickness. Finally, a thin layer of chaff is spread on the surface to facilitate seedlings. The amount per mu is 500 to 700 grams. After cultivation and management, the field maintains a certain humidity, and it can emerge in 4 to 5 days. The seedlings grow weakly in the initial stage, and should be watered and kept seedlings in case of dry weather. When the seedling height is 5-7 cm, the first time the seedlings are started, and the spacing between the seedlings is maintained at 6-7 cm. Seedling height 15 to 17 cm, according to the line, spacing 15 cm each set seedlings. In the absence of seedlings, they were selected to make up the seedlings on a cloudy day. Cultivated weeding usually 3 to 4 times. After the Qi Miao, the first weeding is carried out, combined with the weeding of the topsoil, the manure and livestock waste water and the mixed earth ash, and 1,000 kg per acre is applied. After the second seedling is sown, a mixed fertilizer containing manure and livestock manure and water and mixed fertilizer is applied. 1500 kg per mu; the third time in early September, 2,000 kg of human and animal manure water and 50 kg of superphosphate were used per mu, and after a few days of stacking, the ditch was applied between rows, and the soil was applied after the application; the fourth time was In October, topdressing once, dosage and fertilization method were the same for the third time. After the first and second rounds of spreading, gently sweep the surface and beat the leaves with a branch of bamboo to make the fertilizer fall into the soil. When A. nigrum plant height is about 50 centimeters, the inflorescence that stems are drawn should be removed in batches in time so that nutrients can be concentrated in the roots. Water should be controlled from the seedling stage to early August to promote the main roots to lower. After August, the main root no longer stretches and the amount of irrigation can be increased to promote the growth of the main root. After the rainy season and heavy rain, pay attention to drainage in time. Prevention and control of disease and insects leaf spot disease prevention methods are: timely ditch drainage, reduce the humidity in the field, maintain ventilation and light transmission, enhance plant resistance to disease, before and after the onset of spraying 1:1: 100 Bordeaux mixture or 65% 500% Zexane zinc, Spray once every 7 days, even spray 3 to 4 times. Root rot prevention and control methods are: reduce the humidity in the field, pay attention to dredge drainage, the incidence of 50% carbendazim 1000 times or 5% lime milk gorilla. The prevention and control of nematode disease is: rotation is applied, preferably in paddy field and dry soil; the soil is disinfected during soil preparation: 5 kg of 3% methyl isothiophosate per acre is sprinkled on the soil surface, and then turned into soil. The method of prevention and treatment of ulnar warts is: using artificial deadness to carry out manual killing; 90% of trichlorfon is sprayed with 1000 times liquid. The harvested and processed summer plants were harvested from the winter to the second year before germination. Premature or late will deteriorate the quality. When digging, dig trenches from the end of the raft first. The ditches are 60 centimeters wide and 60-80 centimeters deep. Then the entire root of the Achyranthes root is dug up. Be careful not to cut the root strip. Shake the sediment first, remove the hairs and lateral roots, then straighten the roots, tie each one into 10 pieces, direct sunlight, and collect them in a dry, dry room, covered with grass. In order to make it "sweat," it must be sun dried to dryness in two days and cut off the top of the head and serve as a "hairbow." In order to prevent mildew and insects, hair achyranthes can be fumigated with sulphur for 4 to 5 hours. For every 100 kg of Achyranthes need sulfur 1.5 kg. China Agricultural Network Editor
