摘要
微生物菌肥是缓解我国农业生产对化肥施用依赖的重要途径,试验研究了不同微生物菌肥处理对马铃薯生长发育和产量的影响。结果表明,1%的KS50微生物菌肥浸种处理,马铃薯单株叶面积、主茎长、根长、根冠比分别比CK增加91.2%、57.5%、56.1%和37.5%,此外,在马铃薯的平均薯块重和单株结薯重提高的前提下,该处理产量比对照增产15.7%。1%的KS50微生物菌肥处理薯块有效调控了马铃薯的生长发育状况,在一定程度上调控了产量构成因素,进而实现了马铃薯增产。
Microbial fertilizer as one of the alternatives to fertilizer was an important way to alleviate the dependence of agricultural production on chemical fertilizer in China. The effect of different microbial fertilizer on the growth and yield of potato was studied. The results showed that The leaf area,main stem length,root length and root/shoot ratio of potato were increased by 91. 2%,57. 5%,56. 1% and 37. 5% respectively compared with CK under the 1% KS50 microbial bacteria soaking seeds treatment. In addition,the yield of potato was increased by 15. 7% compared with CK as the average weight and the individual tuber of potato increased.1% KS50 microbial fertilizer treatment effectively control the growth and development of potato,to a certain extent,regulate the yield components,thus achieve the yield of potato increased.
