【摘要】：为了探索多花黑麦草(Lolium multiflorum)—水稻(Oryza sativa)轮作技术在南方农区的应用,对多花黑麦草—水稻轮作种植下土壤肥力的变化进行了研究,研究结果表明:2年轮作种植周期完成后,多花黑麦草—水稻轮作中土壤有机质含量分别增加了5.31%和9.81%、全氮含量分别增加了4.83%和7.5%、全磷含量分别增加13.85%和18.94%,全钾含量分别增加16.96%和21.3%。在南方农区水稻水稻收获后种植多花黑麦草不仅能为农区养殖业提供大量饲草,还能改善土壤肥力,增加土壤养分,为后作水稻生长发育提供良好的土壤条件。
[Abstract]:In order to explore the application of (Lolium multiflorum) rice (Oryza sativa) rotation technique in southern agricultural area, the change of soil fertility under the rotation of ryegrass and rice was studied. The results showed that the content of soil organic matter and total nitrogen increased by 5.31% and 9.81%, respectively, and the total nitrogen content increased by 4.83% and 7.5%, respectively, after the completion of the 2-year rotation of ryegrass and rice, and the soil organic matter content increased by 5.31% and 9.81% respectively, and the total nitrogen content increased by 4.83% and 7.5%, respectively. Total phosphorus content increased 13.85% and 18.94%, total potassium content increased 16.96% and 21.3% respectively. Planting ryegrass with more flowers after harvest can not only provide a large amount of forage for farming, but also improve soil fertility, increase soil nutrients, and provide good soil conditions for the growth and development of rice.
