Abstract
The invention provides bacillus subtilis DLD2 bacterial strain which is preserved in a China general microbiological culture collection center (CGMCC), the serial number is CGMCC NO.3222. The invention further provides a multi-functional biological agent formula and a preparation method thereof; fermentation broth, fulvic acid, zinc sulfate and other components of the bacillus subtilis DLD2 are formulated for preparing the multi-functional biological agent formula which is used for improving soil and continuous cropping resistance; the biological agent has the following functional effect: (1) bio-control microorganisms are utilized to prevent harmful flora from infecting plant and killing pathogenic bacteria, induce the plant to generate disease resistance and prevent seedling withering and rotting; (2) by utilizing synergia effect of formulation of the bacillus subtilis, fulvic acid and zinc sulfate, the root system growth can be induced, plant regeneration and root regeneration are realized, soil hardening is broken, granular structure is formed, no deep tillage is realized, moisture holding and soil moisture conservation is realized, fertilizer damage is relieved and soil fertility is improved.
Description
technical field [0001] The invention is a multifunctional biological agent containing bacillus subtilis, and relates to the formula and preparation method of soil improvement and anti-stubble agent. Background technique [0002] Good soil conditions are a necessary condition for high crop yields, but due to drought, excessive use of chemical fertilizers, unreasonable cultivation and management, continuous cropping and other reasons, soil ecology deteriorates, crop production decreases, and huge economic losses are caused. The main impacts of soil ecological deterioration on crops are root water, vapor, and fertilizer imbalances caused by soil compaction and heavy cropping diseases caused by heavy cropping pathogens. Exploring effective methods to break soil compaction and control cropping diseases has huge economic benefits and social significance. [0003] At present, the methods for breaking soil compaction are mainly mechanical deep plowing and application of soil amendm...
