| 摘 要： | 目的]研究免耕与传统耕作方式种植蚕豆对稻田土壤水分和养分的影响。方法]以云南陆良蚕豆为试材,在免耕和耕作栽培下分别设置株距为253、03、5 cm 3个密度处理,以耕作栽培下种植密度为36.30万株/hm2为对照。在蚕豆成熟期,测定土壤水分和养分指标。结果]不同耕作方式和种植密度对水分和土壤全氮的影响很小;土壤有机质含量为免耕大于耕作;免耕30 cm的处理土壤碱解氮含量最高,为224.90 mg/kg,耕作30 cm的处理最低,为182.67 mg/kg;对土壤速效磷的影响表现为免耕25 cm>免耕35 cm>耕作35 cm>耕作30 cm>耕作25 cm>免耕30 cm;有效钾的变化是免耕25 cm>耕作25 cm>免耕35 cm>免耕30 cm>耕作30 cm>耕作35cm。结论]免耕栽培,能提高土壤的肥力,改善土壤生态环境。

| Abstract: | Objective] The objective of this study was to investigate the influence of planting horsebean with no-tillage and tillage cultivation methods on soil water and nutrient in rice paddy.Method] With Luliang horsebean in Yunnan province as tested material and the planting density of 36.30×104 plant/ hm2 in tillage as CK,3 density series with the plant distance of 25,30,35 cm in no-tillage and tillage were designed.The indexes of soil water and nutrient were measured in horsebean harvest stage.Result] Different cultivation methods and planting densities had a slight influence on soil water and total N.The content of soil organic matter in treatment of no-tillage was more than that in tillage.The content of alkali hydrolysable N in treatment of no-tillage 30 cm was highest(224.90 mg/kg),while that in tillage 30 cm was lowest(182.67 mg/kg).The content of available P among 6 treatments was in order as no-tillage 25 cm>no-tillage 35 cm>tillage 35 cm>tillage 30 cm>tillage 25 cm>no-tillage 30 cm,while the content of available K among 6 treatments was orderly as no-tillage 25 cm>tillage 25 cm>no-tillage 35 cm>no-tillage 30 cm>tillage 30 cm>tillage 35cm.Conclusion] No-tillage could increase the soil fertility and improve soil environment. |
