覆膜栽培对山药生长、产量及经济效益的影响

Effects of Film Mulching Cultivation on Growth,Yield and Economic Benefits of Yam

以鸡皮糙及大和长芋山药为试材,分别设覆膜和不覆膜(CK)2种栽培方式,研究覆膜栽培对山药生长、产量及经济效益的影响。结果表明,覆膜栽培方式对鸡皮糙和大和长芋的出苗都有一定的影响,特别是对出苗天数影响较大,覆膜栽培的鸡皮糙和大和长芋山药出苗天数都为23 d,比对照分别缩短11 d和21 d;覆膜栽培可极显著缩短鸡皮糙山药的芦头长,显著增加鸡皮糙和大和长芋山药的块茎长、块茎粗、平均单薯鲜质量,大薯率比CK分别增加119.99%和162.47%;覆膜栽培可显著增加鸡皮糙和大和长芋山药的产量,分别比对照增产42.54%和33.73%;覆膜栽培对鸡皮糙和大和长芋山药的经济效益都有较大的影响,分别为99 819.90,229 064.25元·hm^(-2),比CK分别增加126.82%和53.23%。

Effects of film mulching cultivation on growth, yield and economic benefits of yam were carried through using Jipicao and Japanese yam as test material, seting two cultivation pattern of film mulching cultivation and the control .The results showed that film mulching cultivation had a certain effect on the emergence of jipicao and Japanese yam, especially having larger effect for emergence days. The emergence days of Jipicao and Japanese yam in film muiching cultivation were all 23 days, reduced 11 d and 21 d compared with control, respectively. Film mulching cultivation could make the rhizomes length of Jipicao yam very significantly shorter, the tuber length, tuber diameter and single plant fresh quality of Jipicao and Japanese yam significantly increase, the percentage of large tubers in- creased 119.99% and 162.47% compared with control respectively. Film mulching cultivation could make the yield of jipicao and Japanese yam significantly increased. The yield increased 42.54% and 33.73% compared with control, respectively. Film mulchingcuhi- ration had larger effects on the economic benefits of Jipicao and Japanese yam, which were 99 819.90, 229 064.25 yuan .hm^-2, respec- tively, increased 126.82% and 53.23% comoared with control, respectively.
