鲁西南夏玉米高产优化施肥技术研究
Optimization of High-Yielding Fertilization Technology for Summer Maize in Southwest Shandong Province
摘要
Abstract
The plot experiment was carried out in field to study the effects of different fertilization meth -ods on yield and related plant characters of summer maize .It was found that the application of high -nitrogen compound fertilizer ,controlled-release fertilizer ,optimized NPK fertilizer could increase the plant stem diame-ter, number of green leaves ,1 000-grain weight and single plant productivity ,so the maize yield increased significantly .The treatments of high-nitrogen compound fertilizer and controlled -release fertilizer had more obvious advantages .Their yields increased by 4.5% and 2.5% compared with optimized NPK fertilization , 13 .9% and 11 .7%compared with single nitrogen fertilizer , and 28 .0%and 25 .5%compared with no fertili-zation , respectively .In conclusion , the applications of high -nitrogen compound fertilizer and controlled -re-lease fertilizer were the regulating direction to further simplify the high efficient cultivation of summer maize in southwest Shandong Province .关键词
