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。

Abstract:

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.

Key words: rice, saline-alkali soil, microbial fertilizers, silicon fertilizer, soil physical and chemical properties
