随着种植业结构的不断优化调整,山药以其高效的经济回报使生产面积迅速扩大。但每株山药一般只用块茎茎端带有潜伏芽的一段作种,称“山药栽子”。为扩大山药种植面积,提高山药繁殖系数,通常利用零余子(山药豆)生产山药种苗(栽子)。山药栽子多年利用也会产生严重退化。所以,一般每隔3～4年利用山药豆繁殖一次。利用山药豆培养的种苗,植株生长旺盛。本文在总结当地农民经验的基础上,提出利用山药豆一年快繁山药种苗的有关技术。一、选种初霜来临前(10月1日左右),选择无病、生长健壮植株的山药豆进行收获,并依据 With the continuous optimization and adjustment of planting structure, yam rapidly expanded its production area with its high economic returns. However, each yam generally only tuberous stem with latent buds for a period, said “yam plant ”. In order to expand the planting area of ​​yam and increase the breeding coefficient of yam, yam seedling (plant) is usually produced by using Zuyuzi (yam bean). Yam planted for many years will also have a serious degeneration. Therefore, the general use of yam bean breeding once every 3 to 4 years. The use of yam beans cultivated seedlings, vigorous plant growth. On the basis of summing up the experience of local peasants, this paper puts forward the use of Yandu beans one year rapid propagation of traditional Chinese medicine technology. First, the selection of early frost before the advent of (October 1 or so), choose disease-free, healthy plant growth of yam beans for harvest, and based on
