Key points of field management of Huang Jing

Rhizoma Polygonatum is a kind of traditional Chinese medicine belonging to Liliaceae, which has a long history in China. Rhizoma Polygonatum has various functions such as tonifying the spleen and moistening the lungs, invigorating fluid and relieving thirst. It can be seen in many traditional Chinese medicine formulations. When we plant Polygonatum polygonatum, the management technology is very important, which directly determines the growth ability of Polygonatum. So how do we manage it? The following editor brings you the key points of Huang Jing's field management, let's have a look!

1. Ploughing and weeding

Ploughing and weeding is essential in the field management of Huangjing. Especially in the seedling stage, the root absorption capacity is weak, if there is no timely weeding, most of the nutrients will be absorbed by weeds, thus affecting the growth of Polygonatum polygonatum. We have to weed at least 4 times during the whole growth period. Intertillage can not only achieve the purpose of weeding, but also improve the quality of soil and promote the nutrient absorption of Polygonatum polygonatum. After ploughing, we should do a good job in soil cultivation to prevent Polygonatum from lodging, but in the later stage, we should stop chemical weeding and give priority to manual weeding.

2. Water and fertilizer management

Nutrient water is an essential substance for the growth of Polygonatum polygonatum, and we can combine it with fertilization when we are ploughing. Apply sufficient mature farm manure, and then increase the amount of farm manure and add appropriate amount of calcium superphosphate in the last application of winter fertilizer. The method of ditch application was applied to the field, and a layer of fine soil was covered after fertilization to improve the conversion rate of fertilizer. Rhizoma Polygonatum has a great demand for water, so we have to keep the soil moist and water it in time when the soil is dry. However, water should not be too much, and if there is stagnant water in the field, we should also do a good job of drainage to prevent the root from rotting.

3. Shading intercropping

Because Huang Jing likes to grow in a cool and humid environment and is sensitive to changes in temperature. Therefore, we should also do a good job of shading when planting, and we can build a greenhouse when shading. Or intercropping corn between rows of Polygonatum polygonatum, because corn is a high-stem crop, and its nutritional demand is low, so it will not have much impact on Polygonatum. When we interplant corn, we have to do it in spring and autumn. And also pay attention to the line spacing, keep it at about 50 centimeters. Otherwise, corn will also rob the growth nutrients of Polygonatum, affecting the growth of Polygonatum, it should not be too far, too far, it will lose the shading effect.

4. Post-management

Polygonatum polygonatum is generally harvested in spring and autumn, but the main harvest time is in autumn, and the quality of mature Polygonatum polygonatum in autumn is better. It is generally planted for about 4 years and harvested in autumn when the aboveground part of Polygonatum polygonatum plant withered. Dig out the rhizome of Polygonatum, then clean it, and do a good job of processing. And also pay attention to do a good job of six kinds of work, generally based on rhizome propagation. The time of keeping seeds is generally in the early spring, and the plants with strong growth and free of diseases and insect pests are selected as the propagation rhizome.

The above is a brief introduction to the main points of Huang Jing's field management. Huang Jing's field management is very important, and we must pay more attention to it when planting. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
