南方棉区棉花苗期施肥的问题,一直存在着不同的看法。一种意见认为“苗期不需要施肥”;另一种意见是“轻施苗肥”;第三种意见是苗肥不但要施,而且还要“施早、施足、施速”。为了探求棉花苗期对肥料的适宜需要量,我们于1980—1985年分别在全区的部分县、市,进行了棉花苗期施用不同数量的氮、磷、钾肥的试验和研究,以期为棉花苗期的科学用肥提供依据。
There have been different opinions on the issue of cotton fertilization in the southern cotton area at the seedling stage. One opinion is that “there is no need to fertilize seedlings.” Another opinion is “light application of seedling fertilizer”. The third opinion is that seedling fertilizer should not only be applied, but also “applied early, applied enough and applied speed.” In order to explore the cotton seedling fertilizer appropriate needs, we in 1980-1985, respectively, in some counties and cities in the region, cotton seedling application of different amounts of nitrogen, phosphorus and potassium fertilizer test and research, with a view to cotton Seedling science to provide a basis for fertilizer.
