| 摘 要： | 在单季稻中施用不同用量的沼液和化肥,使总N控制在210 kg/hm2,基肥P2O5控制在45 kg/hm2,追肥K2O控制在60 kg/hm2,研究单季稻施用沼液后对水稻的生长情况和产量的影响,进而研究沼液的施用对地力的影响。试验结果表明,在沼液的施用量为187.5、225、262.5、300 t/hm2中,水稻产量都比单施化肥有所提高,尤其是施用沼液262.5 t/hm2增产效果达到极显著水平。对施用沼液后的土壤进行了养分测定,检测结果表明:随着沼液用量的增加,有机质、碱解氮、有效磷、速效钾、易氧化有机碳、腐殖酸碳、胡敏酸碳等营养元素的含量都有不同程度的提高,对地力提升效果明显。

| Abstract: | In the application of different dosage of single cropping rice in the biogas slurry and chemical fertilizer,so that the total N control in 210 kg/hm2,basal P2O5 control in 45 kg/hm2,according to K2O control in 60 kg/hm2,research in application of biogas slurry on rice growth and yield.Study on the application effect of biogas slurry on soil fertility.The results showed that rice yield has increased than the single application of chemical fertilizer in a liquid dosage of 187.5,225,262.5,300 t/hm2,especially.Yield reached extremely significant level in the application of biogas slurry 262.5 t/hm2 square meters.On the application of biogas slurry after soil was nutrient determination,test results showed that with the increase of the content of methane,organic matter,nitrogen,phosphorus,potassium,organic carbon,humic acid carbon,Humus acid carbon and other nutrient elements content were improved to different degrees,productivity promotion effect was obvious. |
