粮食和蔬菜間作是既增产粮食,又增产蔬菜的一种栽培方式。粮食产区可以在粮里套菜,不减少粮食生产而增产蔬菜。蔬菜产区可以在菜里套粮,不减少蔬菜生产而增产粮食。我国农民进行粮菜間作已有长久的历史,并且积累了丰富的經驗。本文仅据华北若干地区粮菜間作調查的結果,加以分析和介紹,以供推行的参考。 Intercropping of food and vegetables is a cultivation method that increases grain yield and increases vegetable production. The grain producing areas can grow vegetables in grain without increasing the grain production. Vegetable production areas can be set in the foodstuffs, not to reduce the production of vegetables and grain production. Farmers in our country have a long history of intercropping foodstuffs and have accumulated rich experience. This article is only based on the results of inter-crop investigation in some areas of North China to be analyzed and introduced for reference.
