为了探讨金正大缓控释肥在湘北环湖平丘区水稻生产上增产、增收的效果,2011年在益阳市赫山区毕架山乡中档村进行了晚稻缓控释肥与有机肥、常规化肥定位效应试验。结果表明,缓控释肥前期肥效释放较快,土壤中速效N、速效K含量分别为227.33和180 mg/kg,显著高于有机肥和无肥处理,为水稻前期分蘖生长提供更充足的营养物质,且能起到改善土壤营养的作用;湘晚籼17号在不同施肥处理下产量表现为缓控释肥>有机肥>常规施肥>无肥对照。
In order to investigate the effect of Jinzhongda controlled-release fertilizer on rice production in Pingqiu district of Xiangbei, Hubei Province, in 2011, a controlled release fertilizer of late-crop rice with organic fertilizer and routine fertilizer was carried out in mid-range village of Beijiao Mountain Township, Heshan District, Yiyang City Effect test. The results showed that the release of fertilizer at the early stage of controlled-release fertilization was rapid, and the contents of available N and available K in soil were 227.33 and 180 mg / kg, respectively, which were significantly higher than those of organic manure and no manure, which provided more nutrients for early tiller growth Material, and can play a role in improving soil nutrition; Xiang late indica 17 under different fertilizer treatments showed slow-release fertilizer> organic fertilizer> conventional fertilizer> no-fertilizer control.
