| 摘 要： | 为了弄清山药种茎大小对产量的影响,按大小把山药种茎分成9个等级种植,分别编号为A:10～25 g/个、B:25～50 g/个、C:50～100 g/个、D:150～200 g/个、E:250～300 g/个、F:350～400 g/个、G:450～500 g/个、H:550～600 g/个、I:650～700 g/个。结果表明:种茎越大,总产量越高。当种茎重量达到一定值后,总产量增加趋缓,可供出售的商品产量则下降。通过比较,认为种茎重量在350～600 g/个范围内比较合理。

| Abstract: | To clarify the influence of the size of yam seed tubers on the yield, the seed tubers of Chinese yam were divided into 9 grades for planting according to their sizes and were numbered A （10 to 25 g）, B （25 to 50 g）, C （50 to 100 g）, D （150 to 200 g）, E （250 to 300 g）, F （350 to 400 g） , G （450 to 500 g）, H （550 to 600 g） and I （650 to 700 g） respectively. The experimental result shows that the bigger the tuber is, the higher yield becomes. But when the weight of the tuber reaches a certain value, the yield will increase slowly. The production for selling will decreased. By comparison, we find that it will be better if the weight of each tuber is 350 to 600 g. |
