Abstract:

Four treatments（CK, conventional planting; B, 70% CK fertilizer + treated manure; C, conventional planting + spraying bacterial fertilizer; D, conventional planting + spraying chemical fertilizer）were set up. The chlorophyll content of rice leaves, photosynthetic parameters, plant characters, yield and soil physical and chemical properties of different treatments were compared in this paper. The results showed that there was no significant difference in chlorophyll content among different treatments. Compared with CK, the photosynthetic parameters of C treatment were significantly higher. The effective panicles, total grains, filled grains, and panicle weight per plant of  B treatment and C treatment were higher than those of D treatment and CK. The grain yield of B treatment and C treatment was higher, the yield reached 542.71 kg/667 m2 and 573.73 kg/667 m2, respectively. Compared with CK, the yield of C treatment was increased by 14.95%. The results of soil test showed that there were no significant difference in the contents of As, Zn and Cu between CK and B treatment, but the contents of Fe and Mn of B treatment were significantly higher than CK.

摘要：

设置了常规种植（CK）、70% CK化肥量+处理后的粪水（B）、CK+喷施菌肥（C）和CK+喷施化肥（D）等4个处理，比较了不同处理下水稻叶片的叶绿素含量、光合参数、植株性状、产量以及土壤理化性质的差异。结果显示，叶绿素含量不同处理之间无显著差异。与CK相比，C处理的光合参数显著较高（P<0.05）。考种结果显示，B处理和C处理水稻的有效穗数、总粒数、实粒数和每株穗质量均高于D处理和CK；测产结果显示，B处理和C处理的水稻产量较高，折合单产分别为542.71 kg/667 m2和573.73 kg/667 m2，C处理比CK增产14.95%。土壤检测结果显示，重金属砷、锌和铜含量CK和B处理之间差异不显著，而B处理土壤中的铁和锰元素含量则显著高于CK（P<0.05）。
