通过室内和田间试验,研究了生物有机肥与盐碱土壤养分、根际微生物数量及玉米产量关系。结果表明：生物有机肥改善了土壤,增加了土壤中有机质含量0.22%、降低了土壤pH值,各处理的全氮、速效磷、速效钾含量均显著高于对照,田间试验中处理Ⅱ的全氮高于对照30.95mg/kg;处理Ⅲ的速效磷和速效钾分别比对照高52.95 mg/kg和51.33 mg/kg;不同处理土壤真菌、细菌群落结构存在一定的差异。在对照中由于未施生物有机肥,土壤真菌的数量很少;处理Ⅰ为5.2×105 cfu/g、处理Ⅱ为2.8×105 cfu/g、处理Ⅲ为5.4×105 cfu/g;各施肥处理大区产量处理Ⅰ为852.1kg/667m2、处理Ⅱ847.9 kg/667m2、处理Ⅲ820.8 kg/667m2,分别高于对照5.2%、4.7%和1.4%;说明施入生物有机肥起到了改良盐碱土壤、增加根际微生物数量、提高玉米产量的作用。
通過室內和田間試驗,研究瞭生物有機肥與鹽堿土壤養分、根際微生物數量及玉米產量關繫。結果錶明：生物有機肥改善瞭土壤,增加瞭土壤中有機質含量0.22%、降低瞭土壤pH值,各處理的全氮、速效燐、速效鉀含量均顯著高于對照,田間試驗中處理Ⅱ的全氮高于對照30.95mg/kg;處理Ⅲ的速效燐和速效鉀分彆比對照高52.95 mg/kg和51.33 mg/kg;不同處理土壤真菌、細菌群落結構存在一定的差異。在對照中由于未施生物有機肥,土壤真菌的數量很少;處理Ⅰ為5.2×105 cfu/g、處理Ⅱ為2.8×105 cfu/g、處理Ⅲ為5.4×105 cfu/g;各施肥處理大區產量處理Ⅰ為852.1kg/667m2、處理Ⅱ847.9 kg/667m2、處理Ⅲ820.8 kg/667m2,分彆高于對照5.2%、4.7%和1.4%;說明施入生物有機肥起到瞭改良鹽堿土壤、增加根際微生物數量、提高玉米產量的作用。

The relationship between bio-organic fertilizer and the nutrient of saline soils were under research,number of rhizosphere microorganisms and production of maize by the laboratory and field experiments.The result shows that： 1.The soil fertility was improved,organic matter increased by 0.22%,the values of soil PH decreased,the contents of total N（Tot.N）,available phosphorus（Avai.P）and available potassium（Avai.K）were significantly higher than controls.In field experiments,the content of Tot.N of treatmentⅡwere 30.95mg/kg higer than controls,the content of Avai.P and Avai.K of treatment Ⅲ were 52.95 mg/kg and 51.33 mg/kg higer than controls respectively;2.Soil fungi and bacterial community have some difference among different treatments.The number of soil fungi was seldom in the controls because of no bio-organic fertilizer,The number of soil fungi of treatmentⅠwas 5.2×105 cfu/g,treatmentⅡwas 2.8×105 cfu/g,treatmentⅢ was 5.4×105 cfu/g respectively.3.Production of maize was treatmentⅠ852.1kg/667m2,treatmentⅡ847.9 kg/667m2,treatmentⅢ820.8 kg/667m2,higer 5.2%,4.7% and 1.4% than control respectively.The result showed that apply of bio-organic fertilizer could improve the number microorganisms in rhizosphere and production of maize in saline soils.
