在冀中南平原地区低锌低锰低硼土壤不同作物上施用涂层尿素配合微量元素锌、锰、锌锰或硼。比涂层尿素有显著的增产作用,而且能够改善植株性状,提高产品品质。与涂层尿素相比,配施锌涂层尿素、配施锰涂层尿素、配施锌锰涂层尿素在冬小麦上施用分别平均增产5.6%,6.1%和13.7%,在夏玉米上施用,分别增产11.0%,2.3%和6.8%,且植株穗部性状得到改善,穗粒数、千粒重等显著提高。棉花施用配锌锰涂层尿素和配硼涂层尿素后,分别比单施涂层尿素平均增产13.3%和11.3%,蕾铃脱落减少,纤维和衣分增加。并探讨了不同作物适宜配施的不同微量元素。
Application of coated urea and trace elements zinc, manganese, zinc, manganese or boron on different crops with low zinc, low manganese and low boron in the Jizhongnan Plain. Compared with coated urea has a significant increase in production, but also to improve plant traits, improve product quality. Compared with the coated urea, the application of zinc-coated urea and manganese-coated urea and zinc-manganese-coated urea on winter wheat increased by 5.6%, 6.1% and 13.7%, respectively, on summer maize. Increased 11.0%, 2.3% and 6.8% respectively, and the ear traits of plants were improved, the number of grains per ear and thousand-kernel weight were significantly increased. Cotton with zinc-manganese coated urea and boron-coated urea, respectively, than the single application of urea on average, an increase of 13.3% and 11.3%, reducing the loss of buds, fiber and clothing points increased. The different trace elements suitable for different crops were also discussed.
