The organic fertilizer disclosed by the invention has multiple effects of providing nutrients, improving the soil structure, preventing and treating pests and diseases and the like, can promote the crops to quickly grow, enhances the stress tolerance of the crops, can have favorable preventing and treating effects on nematodes and soil insects, reduces or avoids use of chemical pesticides, enhances the soil fertility, regulates the ecological equilibrium of soil, improves the quality of agricultural products, has no chemical residues, and implements yield increase and income increase of agricultural products.

Biocontrol bacteria strain preventing and curing plant disease

The invention provides a biocontrol bacterial strain for preventing and treating plant diseases and its bacterial agent, belonging to the field of biological control. The strains used are Gram-negative bacteria, identified as Lysobacter enzymogenes, and the strain code is OH11. Strain OH11 has no flagella but has slippage, can produce various extracellular hydrolytic enzymes including chitinase, β-1,3-glucanase and protease, and can effectively inhibit the growth of fungi and bacteria. The antibacterial zone diameters of strain OH11 against Sclerotinia sclerotiorum and Phytophthora capsici were both greater than 22.0 mm; the antagonism against potato ring rot was stronger, and the diameter of the inhibition zone reached 50 mm. The OH11 strain was inoculated into the seed tank, cultivated to the logarithmic growth phase, and the seed liquid was connected to the production tank for cultivation. The medium used in the production tank was the same as that of the seed tank. The liquid fermentation adopts aerobic submerged fermentation and fed-batch process, the dissolved oxygen is 15%-20%, the fermentation temperature is 30°C, the fermentation time is 72h, and the initial pH value is 7.5. After the fermentation is completed, the culture solution is taken out of the tank and directly packed into liquid dosage forms with plastic packaging barrels or packaging bottles, or subpackaged into solid dosage forms with peat adsorption packaging bags. The biocontrol strain OH11 can effectively control plant pathogenic fungi, bacteria, nematodes and other diseases, and the overall control effect is 50%-70%. In the greenhouse pot experiment, the control effects of OH11 on pepper blight and tomato bacterial wilt reached 83.6% and 86.4%, respectively. Strain OH11 has the characteristics of broad antibacterial spectrum, high activity, and environmental safety. In today's serious pesticide pollution, zymolysobacterium and its bacterial agent will be a good substitute.

High-throughput nano-litre micro-droplet forming and fixing method based on microfluidic chip and special chip and application thereof

The invention relates to a high-throughput nano-litre micro-droplet forming and fixing method based on a microfluidic chip and a special chip and an application thereof. The method comprises the following steps: inlets of a continuous phase and a dispersed phase on the chip are respectively connected with two injection pumps through a teflon tube, the continuous phase and the dispersed phase are respectively infused into the chip under the driving action of the injection pumps, and continuous micro-droplets wrapped with single nematodes are formed in a T-shaped micro-droplet generation area; the generated micro-droplets enter in a droplet capture array and are captured in a circular droplet catcher in sequence; and after the micro-droplets are fully captured, the behaviors of the single nematodes in the droplet microenvironment are detected. The invention has the advantages that the microfluidic chip droplet technology is combined with the behavioral analysis to the single nematodes, a great amount of micro-droplets wrapped with the single nematodes are generated and fixed within the short time by using the characteristics of flexible combination and large-scale integration of various functional units on the chip, and the behavioral analysis to the high-throughput single nematodes on the microfluidic chip is realized for the first time.
