根瘤菌与微肥对大豆生理及产量的影响

摘要

为促进大豆生产过程中根瘤菌和微肥的合理使用,采用根瘤菌、微肥、根瘤菌+微肥、对照4个处理,在大豆苗期(V3)、盛花期(R2)、盛荚期(R4)、满粒期(R6)对大豆叶片的叶绿素含量、可溶性糖含量、可溶性蛋白含量进行测定;在大豆成熟期对产量及相关农艺性状进行测定.结果表明:根瘤菌和微肥的使用在大豆不同生育期,一定程度上增加了大豆叶片叶绿素、可溶性糖及可溶性蛋白含量;产量结果表明:无论是单独施用根瘤菌、单独施用微肥或根瘤菌和微肥同时施用均可提高大豆产量,与对照相比根瘤菌+微肥处理产量为2 643.07 kg·hm-2,在各处理中产量最高,与对照相比增产26.02%;根瘤菌处理增产18.33%;微肥处理增产21.73%.%In order to improve the reasonable use of rhizobia and trace fertilizer for soybean,the objective of current study was to investigate the effects of rhizobia and trace fertilizer treatments on SPAD,soluble sugar content,soluble protein content,yield and agronomic characters of soybean.Four fertilizer treatments,including no fertilizer(CK),rhizobia(R),trace fertilizer (TF) and rhizobia + trace fertilizer (R+TF) were adopted.At seedling(V3),flowering(R2),podding(R4),seed filling(R6)of soybean were determined.The yield and agronomic characters of soybean were determined at mature stage of soybean.The results showed that R,TF or R+TF could increased SPAD,soluble sugar content and soluble protein content than CK.The R+TF treament had the highest yield of soybean and the yield of soybean was 2 643.07 kg·hm-2,the increased yield by 26.02%,the R increased yield by 18.33%,and the TF increased yield by 21.73%.
