我们地区是个山区,气温适宜,雨量充沛,一年四季适于作物生长,具有立体农业的特点,各地农民很早就有进行间种套种的习惯,近年来,在农业学大寨的群众运动中,又摸索出一些适于本地间种套种的耕作制度,旱地间种套种面积逐年扩大,产量也不断提高。一九七七年上半年全地区旱地间种套种面积共约四十万亩,其中玉米间种黄豆二十万三千七百亩,玉米间种花生二万九千九百亩,其余是玉米间种杂粮。下半年的旱地间种套种面积也不少。玉米间种黄豆,每亩可以多收黄豆四、五十斤,高的过百斤。黄豆是豆科作物,对土壤有改良作用,
Our region is a mountainous area, with suitable temperature and abundant rainfall. It is suitable for crop growth throughout the year and has the characteristics of three-dimensional agriculture. Farmers in all regions have long had intercropping practices. In recent years, in the mass movement of agriculture in Dazhai, , But also worked out some tillage systems suitable for intercropping within the local area. The area of inter-crop planting in dry land has been expanding year by year, and the output has also been continuously raised. In the first half of 1977, a total area of about 400,000 mu was planted for intercropping dry land in the entire region, of which 207,300 acres were grown between corn and 29,900 acres were planted with peanuts, the rest were maize Miscellaneous grains. In the second half of the dry land intercropping area is not less. Inter-species of corn, per acre can receive more soybeans four or five pounds, high over a hundred pounds. Soybean is a leguminous crop that has a beneficial effect on the soil,
