Planting method for increasing radix polygonati officinalis yield

Abstract

The invention relates to a planting method for increasing radix polygonati officinalis yield, and belongs to the technical field of agricultural planting. The method comprises the following steps: (1) site selecting, namely, selecting sandy soil which is well-drained and is slightly acidic; (2) planting, namely, ditching after the soil is scarified in October to November, bedding a base fertilizer, covering the upper surface of the base fertilizer with bundled straws, then transversely arranging seeds on the two sides of the straws along the trend of ditches at intervals in a staggered manner, covering the upper surfaces of the straws and the seeds with the soil, and flatly placing pine branches or miscellaneous leaves on the upper surface of the soil; (3) performing field management, namely, spraying 1 percent glyphosate serving as a herbicide, and applying an additional fertilizer twice a year; (4) preventing and controlling plant diseases and insect pests, namely, preventing and controlling grey speck disease, rust disease and insect pests. The method disclosed by the invention has very good sterilizing, water retaining and moisture reserving effects, and has good disease resistance and drought and water-logging resistance; the planted radix polygonati officinalis grows well and is high in yield; the average yield per mu is 6,500 kg when the radix polygonati officinalis is harvested in the third year, and is more than one time of the yield of 3,000 kg per mu achieved by conventional planting; therefore, the planting method is suitable for large-area popularization.
