- 摘要:
- 为探讨深松对作物产量的影响,以早熟玉米新品种德美亚1号为试验材料,在7个不同深松模式下,研究了其对德美亚1号玉米品种产量和主要农艺性状的影响和玉米吐丝期不同深度土壤含水量的变化情况。结果表明:德美亚1号玉米品种的产量在处理3时达到最高;不同深松模式对玉米的株高、穗位高影响较大,对穗粗、穗行数等性状影响较小。
- Abstract:
- To discuss the effect of subsoiling on the crop yield,the new varieties of early maturing maize Demeiya No.1 was taken as experimental material to study the effect of subsoiling on the yield and agronomic traits and soil moisture in different soil layers under 7 different subsoiling patterns.The results showed that:the yield of Demeiya No.1 in the treatment 3 reached the highest level;the effect of different subsoiling patterns on plant height and ear height was bigger,and smaller on the ear diameter and ear rows.
