Effects of bast fiber film mat on seedling root growth and yield of machine-transplanted rice

为探明秧盘垫铺麻育秧膜对水稻机插秧苗根系发育和产量的影响,本文考察分析了利用不同种类麻育秧膜所育的水稻机插秧苗根系发育、水稻田间生长动态及产量。结果表明秧盘垫铺麻育秧膜显著促进了秧苗根系发育,提高了秧苗素质,秧苗在移栽田间后有更高的根系活力和生长速率,并最终显著提高了水稻产量;淀粉麻育秧膜比PVA麻育秧膜具有更好的效果,增产幅度达8.9%;秧苗根系质量主要通过影响水稻有效穗数从而影响了产量。研究表明麻育秧膜育秧是一种实施简单但效果突出的水稻机插育秧技术,本研究为麻育秧膜用于水稻机插育秧及其技术改进提供了依据。

Effects of bast fiber film mat on seedling root growth and yield of machine-transplanted rice were studied by raising rice seedling in trays padded with bast fiber films, the seedling root growth, rice devlopment in field and rice yield were investigated. Results showed that padding bast fiber films in trays significantly promoted seedling root growth, improved seedlings quality, enhanced root vigor and growth rate after transplanting into field, and increased rice yield. The starch adhesive bonded bast fiber film increased rice yield by 8.9%, it is more suitable for rice seedling than PVA bonded bast fiber film. Seedling root affected rice yield via effective panicle number. It is summarized that bast fiber film mat seedling is a simple but effective seedling technology for machine-transplanted rice. This study provides an reference for application of bast fiber film in rice seedling.
