| 摘 要： | 通过在甘肃中部干旱区设置的农艺农机结合持续秸秆还田保护性耕作试验,研究了玉米增产量(率)与年限的关系及与土壤理化性状的灰色关联度,并对与有机质关联度高且相关关系显著的肥力因子进行了回归分析.结果表明:秸秆还田保护性耕作2～6a的增产率为2.63%～6.08%.土壤理化性状与增产量的灰色关联序为有机质(0.7456)＞全...

| Abstract: | Through continious experiments of conservation tillage of returning corn stalk to field in arid areas of central Gansu,study was conducted on gray relativity between corn yield and the lasting years of the tillage and soil physiochemical properties,and regression analysis was also made of fertility factors which had high degree of correlation with soil organic matter.The results showed that 2~6 year conservation tillage could increase corn yield by 2.63%~6.08%.The order of degree of correlation between soil... |
