摘　　要：设置不同栽培方式试验,研究秸秆(稻草)套网袋栽培技术对浙江黄岩紫山药(又名紫莳药)的产量、品质和生长发育的影响。研究结果表明,紫山药秸秆套网袋栽培可适当增加单株块茎数,同时块茎也相对较大,因此具有显著的增产效果。秸秆套网袋栽培的紫山药块茎相对细长,外形比较受欢迎,同时还能在生长过程和收获时保护紫山药免受地下害虫危害和损伤,外形美观、光滑、完整,具有较好的商品性;另外,秸秆栽培有利于提高紫山药的山药皂苷、可溶性糖、粗多糖和黏液多糖等营养和保健养分含量。秸秆套网袋栽培也属于秸秆栽培,虽然套网有降低山药皂苷和黏液多糖含量效应,但其营养和保健养分的含量仍然较高,因此秸秆套网袋栽培紫山药的商品性和内在品质均提高。The experiment with different cultivation methods was carried out to study the effect of straw bagged with net cultivation method on yield , quality and development of purple yam （ also named purple Dioscorea alata L.） . The results showed that the tuber numbers per plant of purple yam cultivated in straw bagged with net can be appro -priately increased , at the same time the tuber was also relatively large , resulting in obvious yield increasing .The purple yam tuber cultivated in straw bagged with net had the relatively elongated shape , and avoided underground pest damage and injury in the growth process and harvest .So it had a good commodity with beautiful shape , smooth, integrity;in addition, straw cultivation is beneficial to improve nutritious and healthy compositions , for example, yam saponin, soluble sugar, polysaccharide, mucin polysaccharide and so on .Straw bagged with net cultivation method also belongs to the straw cultivation , though it reduced the yam saponin and mucin content , its nutritious and healthy compositions were still high .The straw bagged with net cultivation method can improve commodity and quali-ty of the purple yam .
