摘要
以玉米品种明天695为研究对象,设置常规施肥(处理①)、绿聚能复合肥(处理②)、中盐红四方玉米缓释肥(处理③)、金正大控释掺混肥(处理④)、鲁西脲甲醛复合肥(处理⑤)、辉煌灿烂控释型掺混肥(处理⑥)、不施氮肥(处理⑦)共7个处理,研究在投入同等养分的前提下,5种缓控释肥对明天695产量性状、养分吸收和籽粒品质的影响。结果表明,处理②和处理⑤的玉米产量、穗粒数、千粒重均显著高于其他处理,玉米籽粒中K含量和秸秆中N、P、K含量也均较高;5种缓控释肥处理下的玉米籽粒中V_(C)、可溶性糖、可溶性蛋白质含量均显著高于常规施肥处理。综合分析可知,绿聚能复合肥和鲁西脲甲醛复合肥是当地玉米栽培缓控释肥的较好选择。
Taking the corn variety Mingtian 695 as the research object,conventional fertilization(treatment①),Lvjuneng compound fertilizer(treatment②),Zhongyanhongsifang corn slow-release fertilizer(treatment③),Jinzhengda controlled-release blended fertilizer(treatment④),Luxi urea formaldehyde compound fertilizer(Treatment⑤),Canlanhuihuang controlled-release blended fertilizer(treatment⑥),no nitrogen fertilizer(treatment⑦),a total of 7 treatments were set up,under the premise of the same nutrient input,the effects of five slow-release fertilizers on the yield traits,nutrient absorption and grain quality of Mingtian 695 were studied.The results showed that the yield,number of grains per spike,and 1000-grain weight of treatments②and⑤were significantly higher than those of other treatments,and the content of K in grains and the content of N,P,and K in the stalks were also higher;the contents of V_(C),soluble sugar and soluble protein in corn kernels under the treatments of 5 kinds of slow and controlled-release fertilizers were significantly higher than those of conventional fertilization treatments.According to comprehensive analysis,Lvjuneng compound fertilizer and Luxi urea formaldehyde compound fertilizer were better choices of slow and controlled release fertilizer for local corn cultivation.
