摘要
调查研究表明,甜菜收获土壤损失的主要影响因素为土壤含水量和甜菜收获机,此外,还有土壤类型、甜菜根形、甜菜产量等20几种影响因素。土壤损失与收获季节降雨量亦即土壤含水量呈显著正相关,随着收获季节降雨量增加,甜菜机械化收获产生的土壤损失明显增加。土壤损失导致土壤营养物质流失,造成土壤肥力下降,引起土壤环境问题。
Investigation revealed that the main influencing factors of soil loss during sugar beet harvest were content of soil water and sugar beet harvester, in addition, there were 20 kinds of influencing factor of soil loss, such as soil type, sugar beet root, sugar beet yield and so on. The soil loss was significantly positive correlated with rainfall in harvest time. The soil loss increased significantly by mechanized harvest of sugar beet with the increase of rainfall. Soil loss resulted in the loss of soil nutrients, which leaded to the decrease of soil fertility, and caused the problem of soil environment.
