Effect Of Organic Materials On Rhizosphere Microecological Environment Of Ginseng

Panax ginseng C. A. Mey is a traditional Chinese herbal medicine. It possesses high applied value and economic value, it would not be used again in cultivating ginseng for a long time, about many a few years. The disease of ginseng is also a main limited factor to ginseng industry. The organic material(corn germ meal and enzymatic fertilizer) are applied in the agriculture more and more. Study the influence of the fertilizer on rhizosphere Microbe of ginseng has important meaning.This paper uses two types of organic materials (corn germ meal and enzymatic fertilizer) to apply on the black soil. Effects of a pot experiment by conventional management and cultivation after birth for a total of 150 days, collecting seven ginseng rhizosphere soil, on the ph value of soil organic nitrogen and microbial biomass C microorganisms Microecological indicators, The results showed:Soil application of corn germ meal and fertilizer enzymes, and the control of soil compared improved significantly ph value As the dose increased, the soil, the rate of increase will be greater, ph value Treatment with A4 and B4 ph value of the largest increases were 0.2 and 0.27 units. Note that two organic materials to soil pH has a good effect, ginseng rhizosphere environment to be improved.After the application of organic materials, rhizosphere soil organic matter content has also undergone a change, soil application of corn germ meal, and the control of soil organic matter, the content of soil organic matter decline ease. Fertilizer application of enzymes and the soil, organic matter content has been greatly improved. Fertilizer application of enzymes to improve soil organic matter content, soil fertility has increased, ginseng root enhanced vitality, improving the soil environment.Fertilizer application of enzymes, the rhizosphere soil nitrogen content increased, with the application rate of increase, total nitrogen larger increase. Shows that, after the enzyme fertilizer for the soil nitrogen increased ability to contribute to the ginseng root nourishment, Soil nutrition microecological environment has improved.Application of corn germ meal soil microbial biomass C first and then decreasing trend. Microbial treatment of the carbon was significantly higher than the control, use corn germ meal 90 days. soil microbial biomass C emerged peak value, enzyme treated soil fertilizer, which controls microbial biomass C was first increase and then decrease trend, Fertilizer application of enzymes and the various treatment groups were double posture, participate in planting the first 30 days of the first peak. Participation in the planting of the 90th day of the second peak. The application of corn germ meal, Soil bacteria and actinomycetes volume of the control group had increased, the line from which the largest increase, eased fungi upward trend, ginseng reduced infection by the disease may be; Fertilizer application of enzymes, Soil bacteria and actinomycetes increase in numbers, ahnost two quite separate bacteria compared with the control group decreased, Application of enzyme bacteria not only benefit the ginseng rhizosphere bacteria, actinomycetes number dramatically, can also inhibit the growth of harmful fungi, enzymes fertilizer to improve soil has good results.
