不同玉米栽培模式对土壤物理性状及产量影响的研究
Effect of Different Cultivation Models on Soil Physical Properties and Yield of Maize
摘要
Abstract
According to the maize production situation in Heilongjiang province ,through comparing the four cul-tivation models that subsoiling techniques ,straw returning to field techniques ,plastic film mulching techniques and conventional tillage model ,the effect of the four different cultivation models on soil physical properties and yield of maize was studied .The results showed that the soil moisture content in the models of straw returning to field techniques and plastic film mulching techniques were all higher than that of the other two models .The soil bulk in subsoiling techniques model was higher than that of the other three models .The soil temperature and yield in plastic film mulching techniques model were higher than those of the other three models .Straw re-turning to field techniques model could improve comprehensive benefits better than the other cultivation mod -els .关键词
