【摘要】：為了探索多花黑麥草(Lolium multiflorum)—水稻(Oryza sativa)輪作技術(shù)在南方農(nóng)區(qū)的應(yīng)用,對(duì)多花黑麥草—水稻輪作種植下土壤肥力的變化進(jìn)行了研究,研究結(jié)果表明:2年輪作種植周期完成后,多花黑麥草—水稻輪作中土壤有機(jī)質(zhì)含量分別增加了5.31%和9.81%、全氮含量分別增加了4.83%和7.5%、全磷含量分別增加13.85%和18.94%,全鉀含量分別增加16.96%和21.3%。在南方農(nóng)區(qū)水稻水稻收獲后種植多花黑麥草不僅能為農(nóng)區(qū)養(yǎng)殖業(yè)提供大量飼草,還能改善土壤肥力,增加土壤養(yǎng)分,為后作水稻生長(zhǎng)發(fā)育提供良好的土壤條件。
[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.
