The cultivation of Polygonatum is to grow in the soil of the field for a long time. The soil generally contains more grass seeds, which will lead to the problem of weeding in the process of planting yellow essence. Let's look at the weeding technique of cultivation of yellow essence. First, the reed grass is laid between the parallel rows and rows of the planted yellow sperm seedlings. The reed grass is harvested before the earing, and then dried. The shortest distance between the ends of the reed grass is 10 cm away from the row of the yellow sperm seedlings; The laying thickness of the grass is based on the fact that the exposed soil is not visible from the top. The laying time of the reed grass is just after the early spring, and the reed grass needs to be dried before the artificial harvesting to prevent the exposure. The leaves of the reed grass are excessively curled, which leads to difficulties in laying and poor uniformity of laying. When harvesting reed grass, the height of the reed grass to be harvested is judged according to the parallel distance between the rows and rows of the seeds or rhizomes. Second, before the laying of the reed grass, it is necessary to carry out a comprehensive fertilization treatment on the planting of the yellow essence; the reed grass is briefly opened in the fertilization process in the later stage of the yellow essence, and the reed grass is restored to the state immediately before the fertilization is completed. 3. When the reed grass is laid, it is laid by two or more superimposed laying methods. The adjacent upper and lower layers of reed grass are placed in the opposite direction. The reed grass is laid once a year for at least two years; the reed grass does not have any after laying. Subsequent management, after the completion of the reed grass laying until the reed grass is completely rotted, it is not necessary to take care of the reed grass, so that it can be stored naturally in the natural state, because the weeds also have a suitable period of germination, etc. When it is completely rotted, it has already passed its germination period, so weeds will not grow. Fourth, using the above weeding method to weed the cultivation process of Huangjing, the experimental results are: no weeds appear in the soil under the reed grass laid, the herbicidal effect is better, the obtained yellow essence does not contain pesticide components, safe, environmentally friendly, and The planted yellow essence also has a certain increase in yield compared to the yellow essence planted by other weeding methods. The use of reed grass to remove the weeds during the cultivation of the yellow essence is to take advantage of the large and non-perishable characteristics of the reed grass. The reed grass can be used to cover the surface between the yellow essence and the row, and then the weed seeds are blocked. The conditions of light, oxygen and other conditions required for growth and development, so that weeds are covered before germination, can make weed seeds be budded, so that weed seeds can not grow out of the ground for growth, thus ensuring weeds The seeds will not absorb the nutrients in the soil, so that the nutrients in the soil are mainly supplied to the growth of the yellow essence, while the small amount of weeds near the yellow sperm seedlings can be pulled out manually, and there is no need to waste too much artificial labor, and the weeding effect is better. It has the advantages of safety and environmental protection. Because the cover of reed grass can prevent the rain from scouring the field and prevent the loss of fertilizer; and because of the cover of reed grass, only part of the rainwater can be infiltrated into the soil through the reed grass during heavy rain, and a large amount of rainwater can be timely Excreting the field from the upper part of the reed grass can also effectively prevent the rotten root phenomenon of the yellow essence caused by a large amount of rainwater, and has the effects of Moisturizing, fattening, and increasing yield.

(Hepatprotective meaning liver/blood protector. Gaba receptor cells uptake alcohol during consumption and the resulting loss of function from loss of GABA uptake produces the effects of intoxication.)
