地膜平铺育秧容易产生膜面与畦面紧贴(贴膏药)现象,造成大面积烂秧,降低了成秧率,因此,选择适宜的隔离物是大面积推广地膜平铺育秧的关键。针对这一问题,从我县农村有丰富的油菜壳资源这一实际情况出发,我们于1989年早杂育秧期间,在文竹乡白源村进行了用油菜壳作隔离物的地膜平 Film tiling seedlings prone to membrane surface and noodles close (paste plaster) phenomenon, resulting in large areas rotten seedlings, reducing the rate of planting seedlings, therefore, the choice of suitable spacer is a large area to promote plastic film tiling seedling key. In view of this problem, starting from the fact that there are abundant rape shell resources in rural areas of our county, during the period of hybrid breeding in early 1989, we carried out the film mulching of rape shell as a spacer in Baiyuan Village, Wenzhu Township
