| 摘 要： | 在麦稻稻三熟制下进行了连续 2 6年定位试验。结果表明 ,长期施用有机肥可以在保持高产稳产条件下使土壤有机质持续增长 ,可以显著影响有机质的增长速度 ,并培肥土壤有机质达到 60gkg- 1的高水平。在此基础上 ,构建了多熟稻田土壤的有机质数量演化数学模型 ,计算得出保持土壤有机质平衡只需厩肥 4.8thm- 2 a- 1。

| Abstract: | A long term field experiment of a triple cereal cropping system (barley double rice) has been carried on for 26 yrs. Results showed that continuous application of FYM increased SOM successively and eventually reached such a high level as 60g?kga?a(c)-1 in SOM content while maintaining high crop yield. The quantity of FYM applied was one of the most important factors which affected the rate of SOM accumulation. A model for the change in SOM was developed. Only 4.8 tons FYM was needed to keep SOM in balance in the barley double rice cropping system. ?1/4WTHZ?1/2 |
