Field management technology of Anemarrhena anemarrhena

Anemarrhena anemarrhena perennial herb, whose rhizome can be used as medicine, has the effects of clearing heat and purging fire, relieving cough and expectoration and calming the fetus. At present, it is in great market demand and is one of the bulk medicinal materials in China. With the depletion of wild resources, the trend of artificial cultivation of Anemarrhena anemarrhena is increasing. To do a good job in field management is an important measure of yield and income. Let's take a look at the key points of field management of Rhizoma Anemarrhenae.

1. The seedlings are fixed

Anemarrhena asphodeloides can be divided into two types: seed propagation and plant propagation. After emergence, there should be time seedlings, strong seedlings should be retained, weak seedlings and diseased seedlings should be removed. The remaining seedlings after the seedlings can be transplanted elsewhere, or if there is a phenomenon of dead seedlings after the seedlings, the seedlings should be replenished in time. When the seedlings grow to 10 cm high, the seedlings can be fixed, and the distance between seedlings can be controlled at 7-10 cm. According to the growth of the seedlings and the corresponding increase or decrease of soil fertility, the soil fertility can generally be sparse.

2. loosen the soil and cultivate the soil

When the seedlings grow three true leaves, it is necessary to loosen the soil and weed, and it is not appropriate to loosen the soil too deep, so as not to damage the roots of the seedlings, resulting in poor growth or death of the seedlings, and weeding should be done frequently to avoid weeds and seedlings occupying the growth space and nutrients. In addition, diseases and insect pests are easy to occur when there are too many weeds. When the plant grows up, it only needs to loosen the soil and weed 2-3 times a year. Because the root system of Anemarrhena anemarrhena is shallow and grows in the topsoil layer, it will be exposed after rain or watering, so we should pay attention to cultivate the soil to avoid lodging.

3. Topdressing

If the plant is to grow fast and the yield is high, fertilization is inevitable. 4000 kg of rotten farm manure and 20 kg of compound fertilizer should be applied in batches per mu, stirred evenly and scattered next to the root system, combined with loosening the soil and covering it under the soil. In addition, it should be watered 1-2 times after topdressing to make the fertilizer permeate, which is beneficial to root absorption. In addition, in the peak growing season of Anemarrhena anemarrhena, foliar fertilizer should be sprayed every other month, which can improve the disease resistance of the plant, promote the growth and expansion of the rhizome and increase the yield.

4. Irrigation

Watering the soil frequently after sowing, keeping the soil moist, watering according to the soil moisture and climate change during growth, watering in time during drought to avoid lack of water, and paying attention to drainage in the rainy season so as not to cause root rot. The overwintering water should be watered before overwintering, so that the plant can survive the winter safely. After the plant germinates in the following spring, it should be watered properly in case of drought.
