我县是个人多田地少的山区,增产的主要途径是改革耕作制度,提高复种指数。但是由于田地大部分沙重、有机质少,土层浅薄,缺肥是三熟高产的薄弱环节。1972年县委和县革委会积极推广了石镇区新店公社张家山大队麦林套种绿肥的经验,收到了良好的效果。 My county is a mountainous area with a few fields and more fields. The main ways to increase production are to reform the farming system and increase the multiple cropping index. However, due to the fact that most of the sand in the field has less organic matter and shallow soil, lack of fertilizer is the weakest link for high-yielding three-cropping. In 1972, the County Committee and County Revolutionary Committee actively promoted the experience of intercropped green manure in Zhangjiashan Brigade in Shizhen District Xindian Commune and received good results.
