树脂包膜尿素与普通尿素配施及树脂包膜BB肥在玉米上增产效果研究

Study on Applying Effect of Blend Rations between Resin-coating Controlled-release Urea and Conventional Urea and Resin-coating Controlled-release BB Fertilizer on Summer Corn

在驻马店市农科所进行了树脂包膜尿素与普通尿素配施试验。试验结果表明,树脂包膜尿素与普通尿素配施处理的产量以控释尿素70%+普通尿素30%处理最好,为7 665 kg/hm2,比100%金正大树脂包膜尿素增产465 kg/hm2,提高了6.5%,比普通复合肥处理增产1 125 kg/hm2,提高了19.0%,比对照增产了2 400 kg/hm2,提高45.6%。金正大控释专用BB肥处理比普通复合肥处理增产90 kg/hm2,提高1.5%。

The experiments of different blend rations between the resin-coating controlled-release urea and conventional urea are conducted in Zhumadian Institute of Agricultural.The results shows that the yield of the blend ration between 70% controlled released urea and 30% conventional urea is the best,which is 7665 kg/hm2.It increased 6.5% compared with the 100% controlled-release urea test,and 19.0% compared with the common compound fertilizer test,and 45.6% compared with the contrasting test.The yield of controlled release BB fertilizer is 6540 kg/hm2,which increases 1.5% compared with the common compound fertilizer test.
