为了提高山药的种植效益，探讨种茎大小与山药生长、产量和经济效益的关系，筛选合适的山药种茎，进行了山药不同大小种茎的种植试验。结果表明：大种茎的山药植株长势旺盛，小种茎的长势纤弱；种茎重量在10～500 g 时，山药商品产量随种茎的增大而增加，种茎重量在500～700 g 时，山药商品产量随种茎的增大而降低；产量和净收益均以种植350～600 g／个的种茎比较理想，种茎以450～500 g／个的商品产量和净收益最高，分别为85833．3 kg／hm2和248923．2元／hm2。结论：山药种植的种茎并不是越大越好，种植种茎大小以350～600 g 为宜。

To improve the planting efficiency of yam and discuss the relationship between the size of the yam seed tuber and growth,yield,economic benefit,the authors conducted an planting experiment on the seed tuber of different weights.Results:the yam plants planted with big yam seed tuber were strong, but the plants planted with small yam seed tuber were slim.The bigger the tuber,the higher the yield;When the weight of the yam seed tuber was 10~500 g,the products for selling of yam increased with the increasing size of the yam seed tuber,While when the weight was 500 ~ 700 g,the products for selling decreased with the increasing size of the yam seed tuber;The yield and net income were ideal when the weight of each yam seed tuber was 350~600 g,When the weight of each yam seed tuber was 450~500 g, the yield was the highest,and it was 85 833.3 kg/hm2 .What’s more,the net income was also the largest, and it was 248 923.2 Yuan/hm2 .It was concluded that the yam seed tuber was not the bigger the better, the optimum size of each yam seed tuber was 350~500 g.
