以机插水稻秧苗为研究对象,研究麻纤维膜作硬盘育秧的衬垫基布以及用于上部覆盖等育秧方式对其秧苗素质及产量性状的影响。结果表明:这两种处理的秧苗相对矮小,但根系发达,盘根能力强,根干重高,根冠比大。麻纤维膜作基布主要是促进了秧苗根长、总根表面积、根分支数、根交叉数、根尖数等指标的增大;在麻纤维膜覆盖中,主要是促进了秧苗根分支数、根交叉数、根尖数等指标的增大。麻纤维膜作基布与其对照(无麻纤维膜作基布)相比,有显著增产效果。结果表明,在水稻育秧中,无论是麻纤维膜作基布还是用于上部覆盖,均能实现省工、节本、增根、壮秧、增产的目的,可在机插水稻育秧上推广应用。
Taking machine-inserted rice seedlings as the research object, the paper studied the effects of the sackcloth lining of the hemp-fiber membrane for the hard-disk seedling raising and the seedling quality and yield traits for the upper covering. The results showed that the seedlings of these two treatments were relatively short, but the root system was developed, the ability of packing was high, the root dry weight was high and the ratio of root to shoot was large. The hemp fiber fabric as the base fabric mainly promoted the increase of root length, total root surface area, root branch number, root cross number, root tip number and other indicators; in the hemp fiber membrane cover, it mainly promoted seedling root branch number , Root cross number, root tip number and other indicators of the increase. Compared with the control (without gingival fabric for fabric), the hemp fiber fabric used as the base fabric had significant yield increase effect. The results showed that in the rice seedling cultivation, both the hemp fiber membrane and the upper covering can realize the purpose of saving labor, saving cost, increasing root, strengthening seedling and increasing yield, and can be popularized and applied in the machine-inserted rice seedling raising .
