【摘要】 高粱合理的施肥量,了粒满丰有机肥不同用量对红缨子高粱产量的。结果表明:在试验设计范围内,随着粒满丰有机肥施用量的增加高粱单产增加,施用量为240kg/667m~2时,产量最高,较施用30kg/667m~2增产48.13%;从经济效益上看,施用量为60kg/667m~2时最高,达629.72元/667m~2,较施用30kg/667m~2增收218.85元/667m~2。生产上建议施用60kg/667m~2的粒满丰有机肥。更多还原

【Abstract】 Reasonable fertilizer rates could increase the yield of sorghum and economic benefits for farmers,effects of different rates of organic fertilizer Limanfeng on yield of sorghum was studiecd.The results showed that the yield of sorghum increased with the increase the utilization of fertilizer in test,the yield of fertilizer of 240 kg /667m~2 was the greatest,it’s 48.13% greater than fertilizer rates of30 kg /667m~2( CK),but the benefits of 60kg/667m~2 was greatest,up to 629.72 Yuan /667m~2,it’s 218.85 Yuan/667m~2 greater than fertilizer rates of 30 kg /667m~2.So 60 kg /667m~2 of Limanfeng organic fertilizer was recommended on production.更多还原
