摘要
在贵州省贵阳市息烽县西山乡柏香山村进行了以沼渣作底肥、沼液浸种、沼液叶面喷施3种因素,8个处理的试验。试验结果表明:1)沼液浸种具有明显的催芽、壮苗和增产作用。出苗率、平均绿叶片数、平均枯死叶片、秧苗平均白根数、苗高分别比常规浸种高7.3个百分点、多0.33片、少0.13片、多0.59条、高0.31 cm。2)沼液的叶面喷施对稻瘟病、纹枯病、稻曲病、二化螟等病虫害的防止有一定的效果。3)大区设置的沼液浸种种植比常规浸种略有增产,但增产效果不明显;沼液叶面喷施两次比不喷施沼液新增产量24.7kg/666.7m2,增产6.33%。
The rice planting experiments with three factors （biogas residues as base fertilizer, seeds soaked in marsh liquid ,marsh liquid spraying on leaf surface） and eight treatments were performed in Baixiangshan Viuage, Xishan, Town Xifeng county, Guiyang, Guizhou Province. The results showed that 1 ）seeds being soaked in marsh liquid played an important part in rice-seed germination, stout seedling and yield increas;2）marsh iiquid spraying on leaf surface prevented and controled some diseases and insect pests, such as pyricutaria oryzae Cav, Thanatephorus cucumeris （Frank） Donk, Ustilaginoideavitens（Cooke） Tak, chilo suppressalis et al. ;3 ） yield per 667m^2 using soaked seed was slightly higher than conventional planting, but marsh liquid spraying twice on leaf surface was higher than conventiolal planting with an increasing yield rate of 6.33%.
