內蒙古西部河套灌区历年来有数百万亩夏茬地。試驗証明,夏茬地复种香豆子每亩可产鮮草1,500~2,000斤,翻压后增加了土壤有机质和有效性养分,从而比現行的麦收后伏翻晒土耕作,能增收粮食60~80斤,故已成为提高当地粮食产量的重要措施之一。但由于没有解决建立群众性的种籽自繁自給基地,使复种香豆难于在大面积上应用。据了解,耕地种植香豆繁种,比种植小麦的經济收益略高些,但减少了播种面积,影响了
Hetao Irrigation District in western Mongolia over the years have millions of acres of summer stubble. Tests show that the summer stubble seed per acre mutton beans can produce 1,500 to 2,000 pounds per acre, after turning pressure increase the soil organic matter and availability of nutrients, so than the current wheat harvesting sun drying, can increase grain 60 to 80 pounds It has become one of the important measures to increase the output of local grain. However, due to the lack of settlement of the masses to establish their own seed base, so that the complex seed coumarines difficult to apply in a large area. It is understood that the cultivation of coumarin species cultivated land, slightly higher than the economic benefits of planting wheat, but reduced the sown area, affecting
