How to plant yellow grass

Xihuangcao is a perennial herb, it is not a large amount of traditional Chinese medicine, but a folk herbal medicine, also known as Coptis chinensis. It can generally be used for the treatment of acute icteric hepatitis, acute cholecystitis, dysentery, enteritis, etc., as well as promoting blood circulation and removing blood stasis. So how to plant Xihuangcao? Today, let's take a look at its planting method.

1. Soil and fertilizer rectification and reform

Wild yellow grass generally grows on hillsides, fields, trails, ditches, streams, and so on. It is a kind of plant that likes light and moisture, but is afraid of stagnant water, so the planting land is generally planted in sandy loam with convenient drainage and irrigation, relatively fertile soil, and the soil is not easy to consolidate. Heavy clay or sandy soil is not suitable for planting. Fine soil preparation, re-application of base fertilizer, good ditch for drainage and drainage.

2. Methods of reproduction

There are three ways of propagation of Rabdosia angustifolia, which are seed propagation, cutting propagation and split propagation. The time of seed reproduction is generally selected when there is more rainfall in spring or when the fruit is ripe in autumn, mainly by means of strip sowing or on demand sowing, the seeds need to be mixed with fine river sand before sowing, and watered after sowing, and covered with straw for heat preservation and moisturization. And cutting propagation to select high-quality branches, and then cut into 12 or 13 centimeters around the small section, soaked with rooting powder to improve the survival rate of branches. Ramet propagation is to use the old roots of the previous crop to grow other new seedlings, and then used for transplanting.

3. Reasonable close planting

As Xihuang grass will continue to reproduce in the subsequent growth process, so the planting density is also very important. In order to benefit more, we need to ensure the yield of Xihuang grass, but also to ensure its quality. Generally speaking, we plant according to the distance of 20 to 25 centimeters between rows and 15 to 20 centimeters between plants.

4. Field management

After Xihuang grass is planted and survived, that is, about ten days, it will grow new roots. During this period, we have to apply fertilizer many times, mainly with urea or fecal water. After waiting for half a month, the feces and urine are applied again, and in the later growth process, fertilizer is usually applied every half a month. After transplanting, it needs to be watered twice a day and covered with plastic film to keep warm and humid. Drainage should be carried out in time after the rain to avoid stagnant water causing land consolidation. Finally, only three or four times a year to carry out intermediate ploughing and weeding to maintain the looseness of the soil and reduce the consumption of nutrients.

5. Disease and pest control

Xihuang grass is originally a kind of weed, so its vitality and resistance are very strong. There are few diseases and insect pests in the whole process of the growth of yellow grass, but powdery mildew and aphids sometimes occur. For powdery mildew, we can use carbendazim or trimethoprim powder to spray, usually once a week or so, two or three times to recover. And aphids we can use aphid nemesis to spray, of course, the effect of trichlorfon crystal is also very effective.

Xihuang grass is generally used in medicine. When we plant it, we should mainly use less medicine to avoid toxin residue in the body of Xihuangcao. This is what the editor wants to share with you today. I hope it will be helpful to you.
