摘要
针对黑龙江省东部典型白浆土地区土壤物理性质和大豆生产环境特点,采用大区对比法开展不同栽培方式(大垄、小垄、平播和正常垄)对白浆土土壤物理性质和大豆生育指标影响的研究。结果表明:不同栽培方式对土壤容重和土壤硬度影响较大,其中平播处理土壤容重增加幅度最大;土壤硬度随深度的增加而增加。另外,不同处理对大豆生育性状影响程度不一致,其中对大豆根瘤数影响较大,大垄根瘤数最多,小垄最少。不同栽培方式下产量差异显著,大垄和正常垄的产量显著高于平播。与其它栽培方式相比,大垄栽培方式有助于改善土壤物理性状,增加大豆根瘤个数,提高大豆产量。
We studied the effects of different cultivations on soil physical properties and soybean growing index in albic soil in the east of Heilongjiang province.We set four treatments,they were wide ridge（WR）,small ridge（SR）,plain sowing（PS） and normal ridge（NR）.Results showed that effects of different cultivations on soil bulk density and soil rigidity were significantly,soil bulk density of PS increased larger than other treatments,soil rigidity increased with soil depth increasing.Meanwhile,each treatment had different effect on soybean growth index,its influence on number of root nodule was much bigger,BR was the most one,SR was the least.Effects of different cultivations on soybean yield were significantly,BR and NR were much higher.The cultivation of BR could improve soil physical properties and increase the number of root nodule and soybean yield.
