开展了地膜覆盖对不同类型多子芋生长及产量的影响研究。试验结果表明,地膜覆盖栽培显著加快芋的生长;显著或极显著地提高单株芋球茎的质量、数量和产量,且球茎质量提高的比率高于球茎数量,熟性越晚,提高的幅度越大;地膜覆盖栽培使芋的芋形指数变大,但一般未达到显著差异水平。另外,地膜覆盖栽培使芋的干物质和淀粉含量下降。
The effects of plastic film mulching on the growth and yield of different types of multi-genelets were studied. The results showed that the plastic film mulching significantly accelerated the growth of taro; the quality, quantity and yield of single taro were significantly or extremely significantly increased, and the rate of bulb mass improvement was higher than that of the bulb. The later the maturity, the more the increase Large; plastic film mulching taro taro index larger, but generally did not reach significant differences. In addition, plastic film mulching decreased taro dry matter and starch content.
