甜菜属喜光作物,光线强弱对甜菜产质量有很大影响。目前,糖农种植甜菜多为带状零星种植,相邻高棵作物遮光限制了甜菜产质量的提高,同时由于茬口混乱,轮作年限不够,加重了甜菜病虫害的发生。为了解决这一问题,必须推行连片种植,统一轮作,以发挥甜菜群体增产潜力,减轻?
Beet is a hi-light crop, the light intensity of sugar beet production have a great impact. At present, sugarbeet planting sugar beet mostly strip sporadic planting, shade of adjacent tall crops limit the yield and quality of sugar beet, at the same time due to chaos stubble, crop rotation is not enough, aggravating the occurrence of beet pests and diseases. In order to solve this problem, it is necessary to promote contiguous planting and unification of rotation in order to give play to the potential for increasing the yield of beet populations and mitigate them.
