What are the key points to note when growing Achyranthes bidentata? A full breakdown of the latest key points

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 already been almost fully harvested, so what followed was another era for Achyranthes bidentata: the era of artificial cultivation. But what issues need to be noted when growing Achyranthes bidentata to ensure its yield and quality? Let us take a look together with Qinnong Net below.

1. Time

The planting time of Achyranthes bidentata is related to the region where it is grown. 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. At this time, the season is hot and rainy, which just suits 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 tubers 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 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 quickly.

Fertilizer and water management is a relatively important part of growing 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 process, two waterings, three fertilizations and three weedings are needed. The first watering is after sowing, and the second watering should wait until Achyranthes bidentata begins to grow tubers. The first topdressing is when the young seedlings grow to about 5 cm, generally using urea and phosphate fertilizer mixed with water for irrigation, averaging 50 kg per mu. The second fertilization is one month after the first fertilization, mainly to promote the seedlings and ensure that the tubers of Achyranthes bidentata smoothly enter the expansion period. The third time is during the rapid tuber growth period, averaging 50 kg of potassium fertilizer and 30 kg of boron fertilizer per mu, and then some special root-strengthening fertilizer for medicinal materials can also be sprayed. Weeding and fertilizing are carried out at the same time.

4. Pests and diseases

The diseases that seriously affect 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 the entire plant will wither. An 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 and leads to plant death, and generally spraying carbendazim is enough. The main insect pests are the silver-striped noctuid and red spider mite. We can adopt manual capture or use pesticides for spraying. The most effective pesticide is 90% trichlorfon 1000-1500 times liquid, or add 40% dimethoate 2000 times liquid for spraying.

The above are some issues to note when growing Achyranthes bidentata. As long as these details are grasped well and planting is carried out in a standardized way according to the methods for growing Achyranthes bidentata, the yield of Achyranthes bidentata will certainly not be too low.
