【摘要】 通过采用玉米宽窄行种植、行间深松作业,结合不同方式秸秆还田的试验研究,明确了玉米宽窄交替休闲种植土壤水分变化的量化指标及在不同深松深度与宽度条件下土壤水分变化规律。试验结果表明,在吉林省中部地区,采用玉米宽窄行种植,行间进行深松作业,建立了土壤水库,可有效蓄积夏秋降雨。更多还原

【Abstract】 Through the wide and narrow spacing maize row planting,deep loosening cultivation between rows and the experimental research on straw into the soil with different ways,we determined the quantitative index of soil moisture variation on maize planted in wide-narrow row alternation form and soil moisture variation rule at different depth and width.The experiment results showed that soil water pool was established,and effectively reserve the summer and autumn rainwater could be effectively reserved by using the wide and narrow spacing maize row planting system and deep loosening cultivation way between rows in the middle part of Jilin province.更多还原
