不同用量长效控释肥对夏玉米生长发育及产量的影响
Effects of Different Application Rates of Long-Term Controlled-Release Fertilizer on Growth, Development and Yield of Summer Maize
摘要
Abstract
Different rates of long-term controlled-release fertilizer (CRF) were applied once when sowing summer maize to explore their effects on maize growth, yield, economic profits and environment.The results showed that compared with conventional fertilization (topdressing high-nitrogen compound fertilizer of 482.1 kg/hm2 for two times at seedling stage and bell stage respectively), except the treatment of 60% CRF with a little decrease of yield, the other treatments all showed increase in production in varying degrees with the range of 1.1%~7.4%, and some showed significant differences.Comprehensively considering maize yield, nitrogen use rate and economic profit, the controlled-release fertilizer could be applied once at the amount of 80% of common fertilizer amount.It could realize laborsaving, high yield, high efficiency and fertilizer saving, and was beneficial for popularization in the summer maize production area in North China.关键词
