- 摘要:
- 以郑单958玉米品种为试材,研究了不同时期和不同深松深度对玉米生育期土层含水量与产量构成因素及其产量的影响。结果表明:播种前、中耕时和秋收后不同深度的深松处理均能提高土壤含水量。深松增强了土壤的蓄水供水能力,促进了玉米的生长发育,改善了玉米的产量构成因素,提高了玉米产量。秋收后深松40 cm效果最佳,较对照提早6 d成熟,增产10.94%。
- Abstract:
- The effect of difference subsoilling on soil moisture content,yield component factors and yield of maize in different growth period was studied using Zhengdan 958 as material.The results showed that different subsoiling treatments could increased moisture content of soil in the spring,in the summer and in the autumn,respectively.Subsoiling could enhance store water capability of soil and supply water capability of soil,promote maize growth,improve its component factors and increase its yield.The best treatment was depth of subsoiling in 40 cm in the autumn,whose ripening date could advance for 6 days than CK and increasing yield by 10.94%.
