广西科学院植物研究所筛选出的桂植捕线菌7号是一种生物制剂,可捕食植物根围附近的多种寄生性线虫(无专化性).在播种时,将菌剂混入有机质肥料中,施在根际,不论是对土壤中线虫的捕食效果,还是对根系免受线虫危害的保护效果,均达到80%以上.该菌剂对以种子为播种材料的植物线虫病,防效尤为显著.其持效期可达一年以上.对人、畜无毒,不污染环境,且可控制土壤中线虫的回升现象.施用菌剂后,对寄主植物还有一定的刺激生长作用.桂植捕线菌7号适应温度范围广泛,在PH4.5～8.0之间,均可正常捕食线虫,捕捉器官形成量多,捕虫势强而稳定,甚至在
Guangxi Academy of Sciences Institute of Plant Screening Guizhi line catching bacteria No. 7 is a biological agent that can predate the plant near the roots of a variety of parasitic nematodes (no specialization.) In sowing, the bacteria mixed with organic fertilizer , Applied in the rhizosphere, both in the soil nematode predation effect, or to protect the root from nematode harm, reached more than 80% of the fungi on the seed sowing material plant nematode disease, especially in the control effect For the significant.Its persistence period of up to more than one year.Human, livestock non-toxic, does not pollute the environment, and can control the soil nematode recovery phenomenon.Using the agent, the host plant also has some stimulating growth. Guizhi Fungus 7 to adapt to a wide range of temperatures in the PH4.5 ~ 8.0 between the normal nematode can be predatory, capture the formation of organs and more insect strong and stable, and even in the
