深耕是增产的基础,尤其在多肥密植情况下,不进行深耕难于获得显著增产效果,这点已为广大群众经验特别是1958年大跃进的事例所证实。 红壤丘陵坡地(即红壤丘陵地)与谷地(即红壤性水稻土)土质粘重,紧实,耕作层浅薄,约3～5寸,而且都有一层紧密坚实的犁底层,当然不利于作物根系伸展与生长发育,因此红壤丘陵区加深耕作层实为必要。 为探求最适宜耕作深度以及结合增施肥料或分层施肥的效果,本所特于1958年在南昌葦塘与新建甘家山分别进行了深耕深度、深耕与施肥关系等方面的研究,现将种植油菜后初步结果介绍如下以供有关方面参考。
Deep plowing is the basis for increasing production. In particular, it is difficult to obtain significant increase in yield without deep plowing and intensive planting. This has been confirmed by the general public experience, especially the Great Leap Forward of 1958. The red soil hilly slopes (ie, red soil hilly land) and valley (ie, red soil paddy soil) soil sticky, tight, tillage layer shallow, about 3 to 5 inches, and have a layer of solid plow the bottom, of course, is not conducive to crop roots Stretch and growth, so red soil hilly areas deeper tillage is necessary. In order to explore the most appropriate tillage depth and the effect of fertilization or stratified fertilization, the institute conducted special researches on the relation between deep plowing depth and deep plowing and fertilization in Wei Chang Nanchang and Ganjia Mountain in 1958. Now we planted rape After the preliminary results are introduced below for reference.
