What are the precautions for planting Achyranthes bidentata?
Achyranthes bidentata is a fairly commonly used medicinal herb. In recent years, the demand for Achyranthes bidentata has been increasing, and the wild resources in many areas have been almost fully exploited, so what followed was another era for Achyranthes bidentata, the era of artificial cultivation. But what issues need attention when planting Achyranthes bidentata to ensure its yield and quality? Let us take a look together below with Qinnong Web.
1. Time
The planting time of Achyranthes bidentata is related to the region. Since Achyranthes bidentata prefers a warm and humid climate, the planting time is generally chosen as summer sowing. In places such as the capital of our country, the time from May to June is generally most suitable for sowing, while in areas such as Henan and Wuhan it is best to plant in July. This is the season of high temperature and abundant rain, which is just suitable for the growth of Achyranthes bidentata. During this period, the planting temperature is best regulated between 20 degrees and 248 degrees, and the lowest temperature must not be 10 degrees. Below 10 degrees, Achyranthes bidentata will stop growing.
2. Density
Achyranthes bidentata uses its tuberous root as medicine, and its branches and leaves can also be used as medicine. Therefore, in order to ensure that it can grow normally, absorb enough nutrients, and receive enough sunlight, attention must be paid to the density in the field when planting. It cannot be too large or too small, so we generally follow a spacing of 15 cm between plants and 20 cm between rows, so that when the plants grow to a certain extent they can still grow rapidly.
3. Fertilizer and water
Fertilizer and water management is a relatively important part of planting Achyranthes bidentata. For the base fertilizer, we generally use farmyard manure and livestock manure, with the amount generally controlled between 3,000 jin and 4,000 jin. During the growth stage, two waterings, three fertilizations, and three weedings are needed. The first watering is after sowing, the second watering should wait until Achyranthes bidentata begins to grow tuberous roots, and the first topdressing is when the sprouts grow to about 5 cm. Generally, urea and phosphate fertilizer are mixed with water for irrigation, averaging 50 kg per mu. The second fertilization is one month after the first fertilization. At this time, it is mainly to promote the seedlings and ensure that the tuberous roots of Achyranthes bidentata smoothly enter the expansion stage. The third time is the rapid growth period of the tuberous roots, averaging 50 kg of potassium fertilizer and 30 kg of boron fertilizer per mu, and then some fertilizer specially used for strengthening the roots of medicinal materials can also be sprayed. Weeding and fertilization are carried out simultaneously.
4. Pests and diseases
What seriously affects the yield of Achyranthes bidentata are leaf spot disease and root rot. The symptoms of leaf spot disease are black spots appearing on the leaf surface, and in severe cases it can cause the entire plant to wither. The effective control method is to spray 1:1:120 Bordeaux mixture or 65% amobam 500 times liquid, spraying once about every ten days, and spraying twice in succession is enough. Root rot causes the roots to rot, leading to plant death. Generally, spraying with carbendazim is enough. The main pests are silver-marked noctuid and red spider mites. We can use manual capture or spray with chemicals to kill them. The most effective chemicals are 90% trichlorfon 1000-1500 times liquid, or add 40% dimethoate 2000 times liquid for spraying.
The above are some issues that need attention in the planting of Achyranthes bidentata. As long as these details are grasped well and planting is carried out according to the methods for planting Achyranthes bidentata in a standardized way, the yield of Achyranthes bidentata will certainly not be too low.
