2008～2009年在吉林省公主岭黑土上研究有机肥磷部分替代化肥磷对春玉米干物质积累、产量、养分吸收和利用的影响。结果表明,有机肥磷替代化肥磷增加苗期或拔节期土壤速效磷含量;与100%化肥磷处理相比,用30%有机肥磷替代化肥磷对玉米干物质积累、子粒产量和磷素吸收没有显著影响,但显著增加营养体磷素的再分配率和对子粒的贡献率,提高了磷素的农学效率。
Effects of Partial Replacement of Chemical Fertilizer Phosphate on Dry Matter Accumulation, Yield, Nutrient Absorption and Utilization of Spring Maize in Gongzhuling Black Soil, Jilin Province from 2008 to. The results showed that the application of organic fertilizer P instead of chemical fertilizer P increased the content of available phosphorus in soil at seedling stage or jointing stage. Compared with 100% chemical fertilizer P treatment, the application of 30% organic fertilizer P instead of chemical fertilizer P had the effects on the accumulation of dry matter, Had no significant effect, but significantly increased the rate of redistribution of nutrients and the contribution of phosphorus to the grains, and improved the agronomic efficiency of phosphorus.
