- 摘要:
- 为了使白浆土地区玉米生产进一步获得高产,研究了三段式犁整地技术模式对玉米农艺性状及土壤理化性状的影响。结果表明:在玉米的整个生育期,利用三段式犁整地技术模式的玉米株高、干物质重和叶面积均高于常规技术;在土壤含水量方面,三段式犁整地技术模式的15~25 cm土壤含水量均高于常规技术模式的土壤含水量1.9~3.6个百分点;在土壤容重方面,三段式犁整地技术模式的20~40 cm土壤容重均低于常规技术模式;在土壤养分方面,两者差异不明显;在产量方面,三段式犁整地技术模式较常规技术模式增产9.6%。
- Abstract:
- In order to obtain higher yield of maize in albic soil area,the effect of three-plow tillage on agronomic characters of maize and soil physical and chemical properties was studied.The results showed that in the whole growth period of maize,plant height,dry weight and leaf area of three-plow tillage were higher than conventional tillage;15~25 cm soil water content of the three-plow soil preparation mode was 1.9~3.6 percentage point higher than conventional tillage; 20~40 cm soil bulk density of three-plow tillage were lowerr than conventional tillage;Difference was not obvious in the soil nutrient;In terms of yield,three-plow tillage increase 9.6% more than the conventional tillage.
