The method is characterized by comprising the following steps: uniformly mixing active components of a pesticide, a reinforcing agent, a sizing agent, a fiber carrier and other additives, feeding the mixture onto a net for drying and molding, or directly preparing into the drug-containing slow-release material, including manufacturing a drug-containing slow-release paper membrane, a seedling pot or a non-woven cloth bag. The invention further provides a use method of the drug-containing slow-release material. The use method comprises the following steps: wrapping seedlings with original soil with the drug-containing slow-release material, or putting the seedlings into the drug-containing slow-release seedling pot or the non-woven cloth bag, filling the gaps with a drug-containing medium or cultivation soil, and watering and performing fix planting; or planting the seedlings by using the drug-containing slow-release seedling pot or the non-woven cloth bag, and subsequently fixing planting directly. The method is simple to operate, effective components of the pesticide can be continuously released after being applied once in planting fixation, crops can be protected for the whole growth season (or for a certain growth period), and practices show that the vegetables cultivated by using the method are low in morbidity of soil-borne diseases and insect pests, and the yield is remarkably increased. The method is high in target property, long in lasting period, low in cost and remarkable in control efficiency.

A bag culture system for large-scale production of solanaceous vegetables comprises a plurality of culture troughs, a plurality of culture bags, a water inlet pipe, a reservoir, a water pump, a fertilizing device, a filter, a drip irrigation main pipe, a plurality of drip irrigation branch pipes and a plurality of emitters. The culture troughs are formed in parallel on the floor of a solar greenhouse by recessing. Two rows of upright culture bags are disposed in each culture trough. The reservoir is located inside the greenhouse. The water pump is disposed in the reservoir, and an outlet of the water pump is connected with a liquid inlet end of the drip irrigation main pipe. An outlet end of the fertilizing device is connected with a liquid inlet end of the drip irrigation main pipe. The filter is disposed on the drip irrigation main pipe. The rear of the drip irrigation main pipe is arranged above one ends of the culture troughs. One drip irrigation branch pipe is disposed above each row of culture bags, and one ends of the drip irrigation branch pipes are connected with the drip irrigation main pipe simultaneously. Each drip irrigation branch pipe is provided with the emitters, while each emitter is above a round hole of each culture bag. The bag culture system has the advantages that production environment can be improved, water and fertilizer can be economized, utilization rate of fertilizer is increased, spread of soil-borne diseases is avoided, and the like.

The invention discloses a bacillus megaterium strain X3 and application thereof to plant growth promotion. The bacillus megaterium strain X3 is preserved in the China General Microbiological Culture Collection Center (CGMCC) on May 11, 2015 with the preservation number of CGMCC No.10803, is obtained through separation of indoleacetic acid, has the characteristics of siderophore production, phosphate solubilizing, ammonia producing, salt tolerance and disease suppression, can remarkably promote crop growth and improve corn yield, and meanwhile, can increase the diversity and the abundance of microbes in soil. The bacillus megaterium strain X3 is quick in reproduction, simple in production process, strong in adversity ability, easy to preserve and conductive to industrial production, and can not only prevent and cure soil-borne diseases but also promote plant growth when utilized to prepare a bio-fertilizer, thereby having a wide application prospect.

The invention relates to bacillus subtillis R31 with broad-spectrum antagonism capacity on plant pathogenic fungi, and in particular provides a bacterial strain (CCTCC NO: M209261) of the Bacillus subtillis R31 as well as growth inhibition action thereof on the plant pathogenic fungi and especially capacity thereof on the biological prevention and control of banana vasicular wilt. The plant endophytic bacillus subtillis is proved to be new bacillus subtillis through obtained 16S rDNA and gyrA and gyrB gene segments as well as BLAST search and comparison on NCBI (National Center of Biotechnology Information) and has better flat antagonism activity on multiple plant pathogenic fungi, better antagonism capacity especially on various soil-borne and vascular bundle diseases, i.e. fusarium oxysporum, rhizoctonia solani, alternaria, and the like, and better prevention and control effect in greenhouses and fields.

The invention provides a phosphate-solubilizing composite microorganism fungicide, which has effective components of pantoea ananatis, pythium oligandrum, trichoderma harzianum and paecilomyceslilacinus. According to the invention, high-efficiency phosphate-solubilizing bacterium-increase bacterium pantoea ananatis with wide applications and fungus of high-efficiency antagonistic crop disease areorganically combined, by applying the composite fungicide of the invention, while soil phosphorin is efficiently utilized and phosphatic fertilizer utilization rate is improved, the effect of antagonistic microorganisms in preventing soil-borne diseases can be sufficiently played, and the effects of solubilizing phosphate to increase yield and resisting diseases to increase yield are achieved. The phosphate-solubilizing composite microorganism fungicide has tremendous application value.

The invention relates to a method for preparing a composite material which takes modified or unmodified attapulgite as a carrier to immobilize bacillus, belonging to the technical fields of microbial fertilizers, biological control of plant diseases, soil remediation and pollution abatement.
