氮肥增效剂在玉米上的肥效试验结果表明能增加玉米穗长和穗粒数及千粒重,从而提高产量,氮肥增效剂用量150 g/666.7m2,分两次施入比对照处理增加145穗/666.7m2,增加穗粒数11.91粒,千粒重增加9 g,增产65.68 kg/666.7m2,增产率达8.07%;比分一次施入(用量100 g/666.7m2)增加有效穗4穗/666.7m2,增加穗粒数5.18粒,千粒重增加3 g,增加产量17.4 kg/666.7m2,增产率达2.02%,具有一定的增产效果,值得推广。
The results of fertilizer efficiency experiment on corn showed that it can increase ear length, number of spikes and thousand kernel weight of maize to increase the yield. The amount of nitrogen synergist was 150 g / 666.7m2, /666.7m2, the number of spikelets increased by 11.91, the grain weight increased by 9 g, the yield was increased by 65.68 kg / 666.7m2 and the rate of increase was 8.07% Increase the number of grains per spike 5.18, grain weight increased 3 g, increase the yield of 17.4 kg / 666.7m2, the rate of increase of 2.02%, with a certain yield increase, it is worth promoting.
