Optimizing the structure of the crop, grass and livestock in the semiarid loess hilly region of Southern Ningxia
摘要
Abstract
According to the coordinated development＇s principle among crop, grass, and livestock industry, the Zhongzhuang experiment of Pengyang County in the semiarid loess hilly region of Southern Ningxia was selected to optimize the structure of the crop, grass and livestock for obtaining the biggest benefit. This study showed that the ratio of wheat, buckwheat and Millet area on the unit area was 28%, 3% and 70%, respectivelyt The economic crops included the corn, the potato, the flax and the triangle bean and their planting percentage on the unit area was 79%, 16%, 4%, and 2%, respeetively and the ration of the cattle, the sheep and pig on the unit cropland area was 3.7, 4.3 and 1.7, respectively. The net income from cropland area was 16 116.84 Yuan per ha and increased by 54.41%. The optimal structure of the crop, grass and livestock would provide the useful information for other similar area.关键词
