| 摘 要： | 筛得一株毒死蜱降解菌CD7,联合植物根际促生菌JD37,研制了一种能修复土壤的农药污染,同时促进植物生长的复合型土壤改良剂.实验结果显示:将CD7和JD37发酵液按体积比1∶1使用,可以促进植物生长,并在25 d内降解土壤中约66.43%的毒死蜱.在载体量相同情况下,蚯蚓粪比滑石粉吸附更多混合菌株.在室温贮藏一个月,活菌数为4.81×10~7CFU/g;制备的复合改良剂与土壤按质量比1∶1使用时,能促进植物生长、提升土壤酶活性、增加土壤中微生物的数量.

| Abstract: | We screened a chlorpyrifos degrading bacteria,Burkholderiasp. CD7.Joint with plant growth-promoting rhizobacteria(PGPR) JD37 to produce a compositesoil amendment,which could restorethe pesticides polluted soil and promote plant growth.Results showed that CD7 and JD37 (at the volume ratio of 1:1) can promote the growth of plants,and within 25 days degrade about 66.43% chlorpyrifos in the soil.Further research found that under the same conditions of carrier dosage,vermicompost can adsorbed more bacteria than talcum powder;after a month preservation at room temperature,the number of living bacterium still maintained about 4.81×107 CFU/g.Carrier and soil,at the mass ratio of 1:1,could optimally promote plant growth,improve soil enzyme activities and increase the number of microorganisms in soil. |
