菜油仅占油菜生物产量的6％左右;占94％的根、茎、叶、果壳、油粕等,可以直接或间接地还田而作为养地物质。但由于其根、茎均较粗硬,因之,在没有浸泡、沤填发酵或机械粉碎条件的地方,多付之一炬,实为可惜。为了解决油菜粗秆旱地还田问题,我们采用了垅作法,使油菜粗秆还土问题得到了初步解决。本试验于1981年在平坝县三小坡完成。 材料与方法 选择一块地力偏下的黄泥地为试验地,该地前作油菜。将菜油收获后剩下部分(离地面约高40cm)地上茎及根部称为粗秆。
Vegetable oil accounts for only about 6% of the bio-yield of rape; it accounts for 94% of the roots, stems, leaves, nutshells and oil-meal, which can be directly or indirectly returned to the soil for cultivation. However, because of its root and stem are harder, therefore, in the absence of soaking, filling ferment or mechanical crushing conditions where more torch, it is a pity. In order to solve the problem of rapeseed stalk dry land returning to the field, we have adopted the stomatal method so that the problem of cole stalk returning to soil has been initially solved. This experiment was completed in 1981 in Pingba County Xiaopo. Materials and methods Select a piece of land under the yellow mud for the test ground, the area before the rape. The remaining part of the vegetable oil harvest (about 40cm above the ground) aboveground stems and roots called rough.
