摘　　要：针对黑龙江省西部地区盐碱地水稻种植过程中存在的有效分蘖少、有效穗数少、产量低、化肥对土壤二次污染等问题,于2019年在黑龙江省泰来县盐碱地水稻生产中进行添加微生物菌剂、纳米硅肥和传统施肥的对比试验,通过调查水稻产量性状、土壤理化性质及微生物含量,明确其增产效果及土壤改良效果。结果表明,添加微生物菌剂和纳米硅肥显著提高盐碱地水稻分蘖数、叶绿素值、叶面积、根长、千粒重、有效穗数、穗粒数及产量,同时改善了土壤的理化性质及微生物含量。试验结果为盐碱地水稻肥料的施用提供了一个新的思路,为盐碱地水稻高产奠定了一定的研究基础。Aims at the problems of less effective tillers,less effective ears,low yield and secondary pollution of the soil by chemical fertilizers during rice planting in saline-alkali land in the western Heilongjiang,a comparative experiment were conducted on the effects of adding microbial fertilizers,silicon fertilizer and traditional chemical fertilization on rice in saline-alkali land in Tailai County,Heilongjiang Province in 2019.By investigating yield traits of rice,soil physical and chemical properties and microbial content,clarify its yield-increasing effect and soil improvement effect.The results showed that the number of tillers,chlorophyll value,leaf area,root length,thousand-grain weight,effective panicle number,panicle number and yield of saline-alkali rice were significantly improved after adding microbial fertilizers and Silicon fertilizers.At the same time,the microorganism biomass,physical and chemical properties of soil were improved.The results of the experiment provide a new idea for the application of fertilizer,and lay a certain research foundation for high yield of rice in saline-alkali soil.
