| 摘 要： | 为大面积推广应用稻田马铃薯免耕覆盖栽培技术支撑提供理论依据,对马铃薯免耕覆盖栽培的稻田土壤理化性状进行了连续定点测定,结果表明:稻田马铃薯免耕覆盖栽培较常规翻耕稻田表层(0～15cm)土壤的孔隙度,微团粒含量,有机质和速效N.P.K含量高,容重却略低;并随着持续免耕有改善表层土壤结构和肥力的趋势;但免耕对深层土壤(15～30cm)的理化性质影响较小.

| Abstract: | The soil physico-chemical properties of rice fields with the continuous potato untilled mulch cultivation pattern were continuously determined to provide the theoretical basis for popularizing the potato untilled mulch cultivation pattern in rice fields on a large scale.The results showed that the soil porosity and content of soil micro-aggregates,organic matter,active N,active P and active K of the surface soil with the continuous potato untilled mulch cultivation pattern were higher than those with the co... |
