摘要
研究了载体型控释肥料在玉米上的应用效果。结果表明,在等养分比例和等养分量处理下,控释肥料处理的经济产量比普通肥料混合后一次性施用处理增加14.9%～17.0%,总生物量增加11.3%～14.5%,氮、磷、钾当季利用率分别提高8.2%～11.2%、4.0%～4.6%和2.7%～5.5%。与普通肥料混合后分2次施用处理相比,经济产量增加10.9%～13.0%,总生物量增加9.8%～13.0%,氮、磷、钾当季利用率分别提高5.8%～8.8%、2.1%～2.7%和7.6%～10.4%。此外,控释肥料还可以改善玉米的品质,子粒的粗脂肪和粗蛋白含量都有所提高。
Effects of supported controlled release fertilizers on maize were studied.The results showed that the controlled release fertilizers could increase economic yield of maize by 14.9%-17.0%,biological yield by 11.3%-14.5%,and improved nitrogen,phosphorus and potassium use efficiency by 8.2%-11.2%,4.0%-4.6% and 2.7%-5.5%,respectively compared with common fertilizers used at one time under the conditions of all treatments with same NPK proportion and amount.To compare with common fertilizers used at two times,the controlled release fertilizers increased economic yield of maize by 10.9%-13.0%,biological yield by 9.8%-13.0%,and improved nitrogen,phosphorus and potassium use efficiency by 5.8%-8.8%,2.1%-2.7% and 7.6%-10.4%,respectively.In addition,the controlled release fertilizers also influenced the quality of maize since the contents of protein and fat in grains were improved more or less.
