莆田县忠门旱地生态农业示范区综合研究Ⅰ.——几种种植制度增产效益研究

The Comprehensive Research on Demonstrative Area of Upland Ecological Agriculture in Zhongmen of Putian I . Study on Yield-increasing Benefits of Several Cropping Systems

生态农业研究从宏观着眼,兼顾经济、社会和生态效益。长期以来,种植结构以粮食生产为主,作物品种老化、退化,饲料作物没有引起重视。为了改变种植业内部结构不合理和单产低的局面,通过更换薯、麦、稻诸作物良种,改革耕作制度和进行不同类型吨粮田开发等研究,取得显著增产增收的效果,粮食单产增加34.8％,人均粮食占有量增加了41.2％,人均收入增加1.69倍。

The research on ecological agriculture is aimed at the macro-agriculture, with the consideration to economic, social and ecological benefits. For a long period, the grain production dominated in the cropping structure in Zhongmen, the aging and degenerated varieties are still used, and the fodder production has not been bringed to the attention. In order to improve the unreasonable cropping structure and low yield in a given area, the improved varieties of sweet potato, wheat and rice have been introduced, the traditional cropping system reformed, the different types of grainyielding models with one-ton harvest developped. As the result, the significant effect of increasing the yield and income has been achieved, which the grain yield in given area increased 34. 8%, the capitation grain pocessing amount increased 41.2%, the capitation income increased 1. 69 times.
