一、棉花施用涂层尿素的效应 据河北省不同生态区,如正定、元氏、邯郸、清苑、衡水、沧县棉花试验,在施肥量、施肥方法相同的条件下,无论是水浇地还是旱地,棉花施用涂层尿素均比普通尿素增产,增产幅度为2.6—25.8％,平均增产14.1％;施用1公斤涂层尿素比普通尿素平均多收皮棉0.376公斤,增加纯收入1.36—3.52元。提高了产量,增加了经济效益。棉花施用涂层尿素增产
First, cotton application of urea coating effect According to different ecological zones in Hebei Province, such as Zhengding, Yuanshi, Handan, Qingyuan, Hengshui, Cangxian cotton test, in the amount of fertilizer, fertilization methods under the same conditions, irrigated land Or dry land, the application of urea coated cotton than the average urea yield, increase rate of 2.6-25.8%, an average increase of 14.1%; application of 1 kg of coated urea urea than ordinary average 0.376 kg more than cash, increased net income of 1.36-3.52 yuan . Increase production, increase economic efficiency. Cotton coated urea application yield
