玉米沼肥营养坨育苗技术研究

Study on the Technique of Raising Maize Seedlings by Using Nutrition Lumps with Biogas Manure

为探索玉米沼肥营养坨育苗对玉米产量的影响，进行了玉米沼肥营养坨育苗试验。土壤与肥料分别按3：1（CK）、2：1、1：1、1：2、1：3的比例配制营养土（体积比），结果表明，加大营养土中的沼肥用量，可不同程度地提高作物产量，其中以1：1比例配制营养土育苗单位产量最高（693．36kg／667m^2），较对照增产9．04％。

The experiment was conducted to investigate the effect of nutrition lumps with biogas manure on the quality of maize seedling and yield. The results showed that the maize yield raised with increment of the biogas manure amount in nutrition lumps and the yield was up to 693.36 kg/667m^2 , 9.04% higher than CK when the volume ratio between soil and biogas manure was 1 ： 1 in the nutrition lump.
