【摘要】 |
Soil-borne diseases of wheat are getting more and more serious in the wheat/maize rotation growing system in northern China. A multifunctional microorganic strain called B1514 was found to have an inhibitory effect against major pathogens of winter wheat soil-borne diseases, have the ability to decompose maize straw, and have the ability to utilize the straw for multiplication. The strain was processed into bacterial agent HAD-1. Field experiments were conducted from 2008 to 2010 to test the control effect of HAD-1 on the major wheat soil-borne diseases, on decomposing ability to maize straw, and on reproductive capacity. Results showed that HAD-1 had significant control effects on sharp eyespot, take-all, and root rot on wheat. The control efficacy at wheat jointing stage was 59.63% to 72.59%, 57.64% to 59.29%, and 54.48% to 63.25%, respectively. The yield loss decreased by 8.67% to 11.70%. The population numbers of the strain B1514 increased 2.68×107–4.83×107 times during the wheat growing season. HAD-1 significantly accelerated the decomposition rate of maize straw in the soil. The decomposition rate increased by 18.7% to 24.3% during wheat growing season. |
