辽西地区应用缓释肥料对玉米产量及生产效益的影响
Effects of Slow Release Fertilizer on Yield and Production Profit of Corn in Western Region of Liaoning Province
摘要
Abstract
The experiment was conducted to study the effect of different slow release fertilizer and fertilization methods on yield and production profit of corn on Da guben experiment base of Liaoning academy of agricultural sciences in Fu xin District in the year 2014 ～ 2015.The results showed that the yield increased by 9.75％ and the production profit enhance about 13.20％,used as urea-formaldehyde compound fertilizer.Without top dressing and the amount of basal fertilize lower 16.67％ using the polymer slow-release fertilizer,which increased yield 4.08％ and production profit 6.72％ than CK.In the meantime,applying slow-release fertilizer improved the corn spike length,spike diameter,spike grain number and grain weight.关键词
