我国东北的产棉区域,由于所处纬度较高,初霜期早,无霜期短,棉花产量一般低而霜后花多,这就成为该地区棉花生产上亟待解决的问题。为此,我们应用了微量元素浸种的方法,进行了促进棉花早熟及提高产量的试验。现将三年的研究结果,简介如后:试验分三部分进行,所用棉花品种均为关农一号。 The cotton producing areas in northeast China have become the problems to be solved urgently in cotton production in the region because of the latitude, the early frost period, the short frost-free period, the generally low cotton yield and the more frost afterwards. To this end, we applied the method of microelement soaking, carried out to promote cotton precocity and increase the yield of the experiment. Now three years of research results, profile as follows: The test is divided into three parts, the cotton varieties are used for agriculture on the 1st.
