复合包埋菌剂对大豆生长及土壤肥力的影响
Effect of Composite Embedding Agent on Soybean Growth and Soil Fertility
摘要
Abstract
The use of rhizobia R12,phosphorous S7,potassium dissolving bacteria Cl produced composite inocula,and treatment with embedded and peat adsorption were made.Soybean as test crop,growth and fertility-related indicators were measured at filling and maturity stages.The result showed that embedding agents compared with control,plants height,dry weight,nodule number and 100 seed weight increased by 16.64％,79.41％,40.83％ and 18.59％.Rhizosphere microorganisms in the soil showed that bacteria,fungi,actinomycetes increased by 68.81％,196.15％ and 21.05％ at filling stage and increased by 59.31％,145.45％ and 20.00％ at maturity stage by embedding agents.Embedd ing agents compared with control,NPK content in crop has increased 71.02％,50.00％ and 32.61％ at filling stage and increased by 67.63％,41.66％ and 22.40％ at maturity stage.The Alkaline hydrolysis N,available phosphorus and available potassium in soil showed that NPK content increased by 5.35％,41.70％ and 13.43％ at filling stage and increased by 4.19％,42.67％ and 21.28％ at maturity stage.The effects of different forms of agents,embedding agents were better than those of peat agents.关键词
