摘要
水稻生态旱育秧沼液喷苗效应试验结果表明：在苗期，苗高和叶龄差异不明显，但能促进茎基宽度增加，达到秧苗敦实，根系生长总根数、白根数、单株分蘖、单株鲜重、成秧率均极显著优于对照，尤其是用沼液原液喷苗，对增加水稻苗期单株分蘖数作用更为明显；在大田期，分蘖率、成穗率、穗长明显优于对照，株高、每穗实粒数、千粒重差异不明显，但结实率对照表现最差。所有参试处理整个生育期均未出现倒伏，大田期只有对照发生轻度叶稻瘟、穗颈瘟、纹枯病。沼液喷苗能有效提高水稻产量，产量为573．89～568．89kg／667m^2，比对照增产12．8％～13．8％。
The experiment was carried out to investigate the effect of spraying biogas liquid at the seedling stage on rice seedling quality and yield. The results showed that there was no significant difference in seedling height and leaf age between the treatments with spraying biogas liquid and CK at rice seedling stage, but the total root number, activity root number, tillers/seedling, fresh weight/ seedling and rate of effective seedling of the treatmentswith spraying biogas liquid were higher than CK, there was no significant difference in plant height, grains/panicle and 1000-grain weight between the treatments with spraying biogas liquid and CK in rice fields, but the tillering rate, effective panicle rate and panicle length of the treatments with spraying biogas liquid were higher than CK and the yield of the treatments with spraying biogas liquid was 573. 89-568.89 kg/667m^2 , 12.8-13.8% higher than CK.
