The majority of Chinese herbal medicines are tubers, and rational spraying of herbal expanders can improve the quality and yield of medicinal materials. Commonly used herbal bulking agents are briefly divided into three categories: First, growth hormones are mainly used to accelerate the growth of plants and promote the transfer of nutrients to the fruits of rhizomes. The second is based on trace elements to increase the root's utilization of fertilizers. The third is based on growth hormone, supplemented by trace elements. The third effect is best.
Herbal expansive agents should be sprayed in a timely and reasonable manner. Spraying too early will cause the tubers to enter the inflating stage in advance, resulting in incoordination of vegetative growth and reproductive growth. That is, if the plants have a large photosynthesis area, they will accumulate and transform more dry matter nutrients more quickly and make the tubers of medicinal herbs expand rapidly. Spraying too late will shorten tuber enlargement growth time and reduce yield.
Spraying is usually 2 to 3 times, and the interval is 1 to 2 times for 5 to 7 days, and 2 to 3 times for 15 to 20 days. After spraying, fertilizer and water management must be strengthened. If there is insufficient supply of nutrients during the expansion period, tubers will have different degrees of spongy, and the quality of herbs will decline.
