In order to achieve higher yields, humans have used fertilizers and pesticides continuously and in large quantities in farmland. The organic matter in the farmland is scarce, and the types and quantities of microorganisms are greatly reduced. Among them, some beneficial microorganisms, such as actinomycetes, Trichoderma, and Bacillus, which inhibit soil-borne diseases, are also included. On the other hand, many pathogens that are harmful to plants are more likely to overwinter in sick bodies. If there is no saprophytic bacteria in the soil, the plant straw can't rot quickly, and the germs will have more chances to survive. It is also because of the above reasons that blight, sheath blight, root rot, and blight have become increasingly rampant.
Two strategies can be adopted for the growing problem of soil-borne diseases. First, continue to strengthen chemical or physical killing measures, and create aseptic conditions for crops as much as possible. This is difficult because the structure and physical and chemical properties of the soil are complex, and many factors affect the sterilization effect; even if it can be done temporarily, once a new pathogen enters, it will quickly become a disaster due to lack of natural inhibition. Another strategy is to increase the number and quantity of microbes in farmland soils, create a rational, balanced and stable microflora and rely on their competition, occupancy, and heavy parasitism to inhibit the growth of pathogens. Practice has proved that this is a reasonable strategy for continuous disease prevention.
To achieve ecological balance and inhibit soil-borne diseases, on the one hand, it is necessary to continuously increase soil organic matter, including farmyard manure (fertilizer, compost), industrial production of organic fertilizer, straw returning, and planting grasshoppers and other green manure crops. Organic matter not only contains abundant nutrients, but also forms agglomerate structure in the soil, and is also a substrate for cultivating various microorganisms. On the other hand, it is necessary to increase the type and quantity of beneficial microorganisms, that is, to apply a certain amount of bacterial fertilizer. Bacterial fertilizer is also called biological fertilizer and bacterial fertilizer. Rather, they are bacteria rather than fertilizer, the main ingredient is not a nutrient, but a large number of microorganisms. Its function is to improve the nutrient conditions of the crops and decompose the organic matter in the soil through the activities of microorganisms, so that they become nutrients that can be absorbed by plants, just as the food that people eat must be digested to be absorbed. If the straw is returned to the field without the help of microorganisms, it can not only be used by plants, but also may contribute to the growth of pathogens; on the other hand, no matter how much more bacteria are scattered in the poor soil, it is impossible to convert nutrients out of thin air. Beneficial microorganisms will also starve to death. Only when organic matter and beneficial microorganisms coexist can the effect of fattening and disease prevention be achieved.
A novel multi-effect organic fertilizer implanting beneficial microorganisms in a large amount of organic substances in an appropriate proportion, the microorganisms comprising nitrogen-fixing bacteria, nitric acid bacteria, phosphorus-dissolving bacteria, photosynthetic bacteria capable of increasing or transforming nutrients; and yeast capable of decomposing organic matter; It is capable of secreting plant growth stimulating hormone and inhibiting pathogens of Trichoderma harzianum, Myxobacteria, Actinomycetes, and some Bacillus and Pseudomonas. The fertilizer has the advantages of long-acting, quick-acting, increasing production and preventing disease, and is worth promoting. Its pros and cons mainly depends on the type and quantity of beneficial microorganisms implanted.
Here also remind everyone that bacterial fertilizer and multi-effect organic fertilizer should not be stored for a long time, to avoid high temperature, water immersion, generally can not be mixed with fungicides.

Industrial Steel Buildings
Industrial steel structure buildings have a wide range of uses, and the high cost performance is worth choosing!
Industrial steel structure buildings are used in various industries, and their construction is convenient, and different steel structure buildings can be designed, which can also meet the needs of daily factories. Let's introduce the specific advantages of using steel structure buildings.
Wide range of uses
The scope of application of industrial steel structure buildings is still very wide. In addition to the use of factories as Steel Structure Workshop, some daily storage centers use Steel Structure Warehouse as warehouse, as well as gymnasiums, dormitories, etc., are actually buildings that can use steel structures. And not only the ground floor can be built, as long as the design is reasonable, then high-rise and multi-storey buildings can be constructed and applied.
Simple construction
Compared with traditional building construction, the construction of the steel structure itself is very simple, and all components are prefabricated and have certain standard sizes, which can be installed directly. The construction efficiency is high, and the construction of the plant can be completed in a short time. And generally it can be directly spliced, which greatly shortens the construction time, and the construction of large-scale buildings can be completed in less than one month.
High durability
Industrial steel structure buildings can be used for a long time, not just temporary use for a month or two, and the stability of the steel structure is also guaranteed. Moreover, the daily maintenance of the building is simple, and the design and construction of the building can be completed directly through computer design. Even if it is used in bad weather, there will be no problems, and it is suitable for long-term use.
beautiful and practical
Steel structure buildings come in many different colors, and manufacturers can also provide customized processing services. The design of the building is simple and beautiful, and it can also be decorated internally. Such a building has strong flexibility in use and can meet the requirements of different projects for long-term use.
Cost discount
Industrial steel structure buildings are light in weight, and the price of steel structures is favorable, and the cost performance is still good. Because of the high construction efficiency of its buildings, labor costs are also very cost-effective. It only needs to complete the design and construction, and the building can be put into use immediately, and the overall cost performance is also good.
