摘要: 在密度、田间管理水平相同的条件下,把5种施肥万式置于同一地块中,进行3个品种的肥料对比试验。结果表明,不同处理的品种间、不同施肥万式间的高梁产量都存在着显著差异,对产量作用最大的是品种间的差异,其次是不同施肥万式。在试验的3个高梁品种中,赤杂28的产量最高。在不同的施肥处理中,以磷酸二铵150kg/hm^2和硫酸钾150kg/hm^2作种肥一次性施入、拔节期追施尿素225kg/hm^2为最佳施肥万式。

Abstract: To make three varieties of fertilizer comparison test, five kinds of fertilization treatments were put on the same plot under the same density and field management level. The results showed that different varieties and different fertilization treatments had significant differences on sorghum yield. The difference between varieties had the largest effect on yield, followed by the different fertilization forms. In three tested sorghum varieties, red miscellaneous 28 had the highest yield.In different fertilization treatments,the best fertilization method was using DAP150 kg/hm^2 and potassium 150 kg/hm^2 as the seed fertilizer and a one-time applied,and using 225 kg/hm^2 carbamide urea at thejointing stage.
