Description
Technical field
The invention belongs to technical field of biological organic fertilizer, and in particular to a kind of biology with prevention and control soil-borne disease function has
Machine fertilizer and preparation method thereof.
Background technology
As aquaculture industry of China separates with planting industry, scale, intensive culture industry institute are dissolved without enough farmlands
Substantial amounts of Stock raising waste is produced, ecological environment is caused to have a strong impact on.And the chemical fertilizer amount of application cumulative year after year in farmland,
The contribution bottleneck of crop yield is increasingly highlighted.
Agricultural production fertilising feature in China's is to fertilize, a large amount of chronic administrations of chemical fertilizer cause crops quality to drop partially
It is low, cause soil hardening, organic matter decline, soil and crop root Tiny ecosystem destructurized, even more result in soil and pass plant
What disease was spread unchecked.Soil-borne disease refers to that pathogen is lived in soil, from crop root or stem infringement crop when condition is suitable
Caused by disease.The ashamed thing soil-borne disease of agriculture is distribution wide, harm weight, is difficult to the crop disease prevented and treated.It is universal in countries in the world
Occur, China is particularly acute, and according to incompletely statistics, long-term onset area is up to more than 600 ten thousand hectares.Current disease prevention and control mainly according to
By chemical prevention and control, but the problems such as chronic administration chemical agent also results in medicament residual and environmental pollution;In agriculture conventional pipe
In reason, as long as phytopathogen can have the several years in soil, crop rotation means receive greatly to limit to when disease breaks out, and the mode such as grafting is even more
Substantially increase prevention and control cost.Therefore, with reference to disease-resistant variety seed selection and possess the biological prevention and control of beneficial bacterium etc. of antagonism function
Preventing control method by be following soilborne fungal pathogens prevention and control trend.
Biological organic fertilizer, which has, often applies the advantages of not bringing any toxic side effect but, while dosage is big, has and fosters and apply fertilizer
The effect of soil.Under the support energetically of national organic matter Improving Project, country encourages large area application of organic fertilizers.But city
There is presently no the bio-organic fertilizer product to soil-borne disease prevention and control function on field.
The content of the invention
The invention provides a kind of economical and effective, the biological organic for improving crop yield, having prevention and control soil-borne disease function
Fertilizer.
Present invention also offers the preparation method of the biological organic fertilizer with prevention and control soil-borne disease function.
The purpose of the present invention is achieved by the following technical solution:
