摘  要

楊紹榮、張敏郎。2003。生物分解膜在落花生畦面敷蓋栽培之初步研究。台南區農業改良場研究彙報41:17~27。

採用天津丹海、Degra-Novon、Mater-Bi及多麗等四種生物分解膜進行秋作落花生畦面敷蓋栽培評估,初步結果顯示:各供試敷蓋膜均可提高落花生種子萌芽出土率,播種後7天較露地栽培之萌芽出土率平均增加51.4%,致植株生育快速及提早開花。各供試敷蓋膜,在播種後24天之開花率較傳統PE膜及露地栽培分別平均增加16.8%及19.3%;播種後27天,露地栽培生長較為緩慢,開花也較遲緩,其開花率僅44.4%。植株開花授粉後,子房柄伸長對於供試分解膜之穿透率不一,介乎於13~20%之間,惟Mater-Bi生物分解膜高達30.8%,值得進一步探討其原因。另落花生敷蓋多麗分解膜,由於空莢之比率較少,僅21%,而小區總莢果數較多,且鮮莢果及種仁均較重,所以單位面積產量也較佳。就本試驗第一年之初步觀察得知:採用生物分解膜進行落花生畦面敷蓋是可行的,惟敷蓋之最適合材質如膜的厚度、播種方式如直播或移植及栽培模式與經濟效益等,仍需更進一步探討與評估。

Preliminary Study of Biodegradable Mulching Films in Peanut

Yang, S.R. and M. L. Chang

Summary

Biodegradable mulching films of Dan-hai, Degra-Novon, Mater-Bi and Poly for peanut cultivation were evaluated in this study. The results indicated that there are 51.4% higher in percentage of seed emergence for mulching with degradable films,7 days after sowing. Compared to bare cultivation, there are 16.8%~19.3% higher in flowering for mulching with degradable films,24 days after sowing. The percentage of flowering was only 44.4% for the bare cultivation,27 days after sowing .The percentage of penetrating of gynophore for mulching with degradable films were mostly between 13-20%,but it reached 30.8% for the plants mulching with Mater-Bi biodegradable film. Due to has less empty pot, more pot number and heavier in pot and kernel for plants mulching with poly degradable mulching film, therefore it got better yields compared to other mulching films.
