控释尿素与普通尿素掺混对玉米产量影响的试验研究

Study on the Effect of Different Blend Rations between the Controlled Released Urea and Conventional Urea on Corn

在驻马店市的新坡村与和兴农场进行了不同比例控释尿素与普通尿素掺混对玉米产量影响的试验,试验结果表明,施用控释尿素70%+普通尿素30%处理的玉米产量最高.新坡村与和兴农场的产量分别为6780 kg/hm2和6 550 kg/hm2,比100%控释尿素处理增产5.1%和5.6%,比100%普通尿素处理增产16.2%和17.8%,比对照增产22.1%和20.8%;控释尿素70%+普通尿素30%处理与其他处理之间玉米的产量差异达1%显著水平.该试验对玉米经济性状的影响主要在穗粒数和百粒质量方面,对穗长、穗粗和株高影响不大.

The experiments of different blend rations between the controlled released urea and conventional urea were conducted in Xinpo village and Hexing farm, respectively. The results showed that, the yields of the blend ration between 70 % controlled released urea and 30 % conventional urea were the best, which were 6 780 kg·hm^-2 and 6 550 kg·hm^-2,for Xinpo village and Hexin farm respectively. It increased 5,1% and 5.6 % compared with the 100 % release-controlled urea test, and 16.2 % and 17.8 % compared with the 100 % conventional urea test, and 22.1% and 20.8 % compared with the contrasting test. The significant difference between these tests amounts to 1%. The experiments produced little influence on ear length, ear width and stock height of corn, bigger influence on number of kernels and 100-kernel weight.
