胡萝卜出苗缓慢,播期和苗期正是杂草旺盛生长期.尤其土壤水肥条件好的蔬菜田,往往施用大量未腐熟有机肥,其中含有较多草籽,一旦条件适宜,杂草不但生长快,而且密度大,很容易造成草荒,严重者甚至毁种. 本试验的目的是在胡萝卜出土及幼苗期,应用不同的化学除草剂进行田间除草试验,筛选出适宜除草剂,以便在生产中推广应用. Carrot emergence is slow, sowing and seedling stage is the weed growing season.Especially in the field of soil water and fertilizer good vegetable fields, often using a large number of non-decomposed organic fertilizer, which contains more seeds, once the conditions are right, weeds not only grow fast , And the density is high, it is easy to cause grassland waste, severe or even destroyed species.The purpose of this experiment is to apply different chemical herbicides to field herbicidal test in the period of excavated and seedling stage of carrot, to screen out suitable herbicides for promotion in production application.
