种植制度,是指各种作物在农田上分布配置和相互结合的方式和方法,主要包括作物布局和轮作方式两个方面的内容。它是农作制度(耕作制度)的中心环节。黄土高原水土流失重点县,大都处于半干旱地区。这类地区,农田种植制度改革的核心,是要将目前单一的粮食种植方式改变为粮草结合的种植方式。这既是调整当地农林牧结构,实现土地合理利用的基础,也是稳定地提高当地农田生产力的关键所在。实行粮草结合的种植制度要因地制宜,在干旱和旱地农业分区的基础上进行。胡耀邦同志 Planting system refers to the ways and means of distribution and arrangement of various crops on farmland, including crop layout and rotation mode. It is the central part of the farming system (farming system). The key counties of soil and water loss in the Loess Plateau are mostly in semi-arid areas. In these areas, the core of the reform of the farmland cultivation system is to change the current single grain planting mode into a forage-straw combination. This is not only the basis for adjusting the structure of local agriculture, forestry, animal husbandry and animal husbandry as well as realizing the rational utilization of land, but also the key to the steady improvement of the productivity of local farmland. The system of combining forage and grass shall be based on the local conditions and on the basis of arid and dry-land agriculture zoning. Comrade Hu Yaobang
