FM是从海南岛芒果根际土壤中分离到的一株具有解磷作用的菌株,通过纸床发芽法及盆栽试验研究其促生作用。结果表明,FM菌株在纸床发芽试验过程中,其10倍发酵液能有效促进黄瓜种子的发芽,而西瓜和番茄种子在100倍液中发芽效果更好;根据经发芽实验所得最佳促进浓度研究解磷菌株FM对番茄、西瓜和黄瓜3种作物生长量的影响。结果表明,经菌液处理过的番茄、黄瓜和西瓜植株,其植株株高、根长和茎围、地上部及地下部重量均高于对照,与对照差异达极显著,可见其对番茄、黄瓜和西瓜幼苗的生长都有促进作用。利用其作为土壤肥力的优势菌株,可有效提高作物的产量。
FM is a strain of phosphate-solubilizing bacteria isolated from the rhizosphere of mango in Hainan Island. It was studied by the paper-bed germination and pot experiment. The results showed that FM strain could effectively promote the germination of cucumber seed in the paper bed germination test while the watermelon and tomato seeds germinated better in 100 times liquid. According to the optimum promotion concentration The effects of phosphate solubilizing strain FM on the growth of three crops, tomato, watermelon and cucumber were studied. The results showed that the plant height, root length and stem circumference, shoot weight and shoot weight of tomato, cucumber and watermelon treated by bacterial culture were higher than those of the control, Cucumber and watermelon seedling growth has a promoting effect. Use it as a dominant strain of soil fertility, which can effectively improve the crop yield.
