Duplex regulator for preventing and treating continuous cropping obstacle of facility cultivation and preparation method thereof

Abstract

The invention relates to a dual regulating agent for preventing succession obstacle in protecting cultivation, with components according to following weight proportions: 1-10% of functional bacterial agent of bacillus, streptomycete or gliotoxin of 107-108 cfu / g counted by live bacterial content, 70-98% of progressional agent for organic functional expression such as fermentation organic fertilizer, grass peat or / and brown coal mixture, 5-20% of progressional agent for inorganic function such as zeolite, medical stone or shale. The invention discloses the agent and ite preparing method, and the action is realized by regulating both the immune and growth of root microecology and host, adsorbing functional bacterial onto prossessional agent, considering plant root system, root microorganism and root soil as a microecological system and regulating the population and quantity of microorganism in root system and physicochemical feature of soil to inhibit the population of pathogenic bacteria.

Description

technical field [0001] The invention relates to a regulating agent for preventing and controlling obstacles in facility cultivation continuous cropping and a preparation method thereof, in particular to a preparation and a preparation method for preventing and controlling facility cultivation continuous cropping obstacles through dual regulation of rhizosphere microecology and host immunity and growth. Background technique [0002] In recent years, the cultivation area of ​​protected vegetables, melons and fruits has expanded year by year, and is developing in the direction of specialization and intensification. With the extension of the continuous cropping period, the continuous cropping obstacle has become one of the main bottlenecks restricting the sustainable development of protected cultivation.

With the extension of the continuous cropping period, the continuous cropping obstacle has become one of the main bottlenecks restricting the sustainable development of protected cultivation

The pathogenic factors of continuous cropping disorders include pathogenic microorganisms (fungi, bacteria, viruses, nematodes) infectious diseases (soil-borne diseases), as well as physiological diseases caused by salinization, autotoxic substances, etc., and sometimes it is a combination of multiple factors Effect (Zheng Junhui, Chinese Vegetables, 2004 (3): 56~58), there is no effective control method both at home and abroad at present

Although measures such as stubble turning and soilless cultivation are effective, due to the constraints of land conditions, input costs and other factors, the popularization of technical measures is limited

Chemical control is currently the main method used, and the chemical preparations with better control effect are haloalkane soil fumigants, such as methyl bromide, chloropicrin, etc. ( http: / / www.sdngx.com / Article / Class3 / Class24 / Class45 / 200503 / 531.html ), but because the use of chemical agents can only prevent and control the infective diseases (soil-borne diseases) of pathogenic microorganisms (fungi, bacteria, viruses, nematodes) concentrated in the roots of vegetables, it is not effective for continuous cropping obstacles caused by various pathogenic factors. It is ideal, and the input cost is high. In actual operation, there are still blindness in the method of use and dosage, so that there are disadvantages such as drug-resistant bacteria and pesticide residues.

Biological control has been widely valued by countries all over the world for its high efficiency, pollution-free, low cost and other characteristics, and has become a hot spot in current research and development. For example, the 99112704.8 patent "biological agent and preparation method" discloses a biological agent, but It only has obvious control effects on soil-borne diseases, and has low and unstable control effects on continuous cropping obstacles caused by various factors.

And 200410041507.8 patent "a fertilizer that can eliminate crop continuous cropping obstacles and its production method", 03144289.7 patent "crop continuous cropping obstacle regulator", 200410092464.6 patent "a multifunctional fertilizer" and 200410002186.0 patent "seaweed, fulvic acid microbial fertilizer The preparations for the prevention and treatment of continuous cropping obstacles mentioned in "Production Methods" are all organic or inorganic fertilizers, which can only control specific root diseases, nematode damage or physiological obstacles as a single target.
