Nowadays, the "bio-fertilizer" brand is mixed and mixed. In addition, some people always want to use the "high-tech" signboard to farm farmers, and profit from it, making the users, especially the farmers, feel at a loss. For example, some people actually put as little as possible. Biological fertilizers are nicknamed “microbial fertilizers†or “microbial fertilizersâ€, and whether the fertilizers contain true “functional bacteria†that have been purified and rejuvenated by regular processes, “bacteria†that are both harmless and unhelpful, or “ Some harmful bacteria are also referred to as "biological fertilizers" or "microbial fertilizers"; others do not randomly label the number of bacteria on the packaging bags according to national regulations, and some general products have a high bacterial content. Hundreds of millions per gram, and so on. Therefore, users and distributors should carefully identify that the state has strict regulations on various indicators of microbial fertilizers. If you are not sure, you should ask experts or local authorities to help identify them and avoid being deceived and damaged.
　　
　　
How do distribution agents and general users choose the right microbial fertilizer brand? Here are some noteworthy aspects, for reference:
　　
　　
First of all, there should be a clearer understanding of "biological fertilizers". Due to a variety of historical reasons, "fertilizer" and "microbial fertilizer" is the name that has been abused in the market, microbial fertilizer, fertilizer, microbial fertilizer, microbial fertilizer, microbial agents, compound microbial fertilizer, Compound microbial fertilizers and biological fertilizers are often regarded by the average person as the same thing. In fact, they are different, even if people in the industry have to accept this reality. Whatever the name, it should be common basic meaning, that is, in general, microbial fertilizer (by many non-professionals called "bio-fertilizer"), it is a kind of microbial preparation containing vitality, with nitrogen fixation, phosphate solubilizing or potassium function, promoting absorption and utilization of the plant nutrients, increase fertilizer efficiency, reduce the amount of fertilizer, effective restoration of fertility, reduction of soil plate junction, for improving the soil fertility and enhance crop resistance, increase crop yields, improving crop quality . Which contains a plurality of functional microbial into the soil, a large amount of secondary metabolites in the growth and reproduction, these products can promote the formation of the aggregate structure of soil. The formation of agglomerate structure makes the soil loose, soft, water and fertilizer-enhanced, water, gas and heat more coordinated, reducing soil compaction, conducive to water retention, fertilizer retention, ventilation and root development, providing a comfortable growing environment for crops. . Improve the physical and chemical properties of the soil, strengthening the activities of beneficial microorganisms in the soil, thus contributing to the decomposition of organic matter transformation, some also produce a variety of nutrients and irritating substances that in turn stimulates the growth of microorganisms secrete more beneficial substances To promote crop growth, and ultimately achieve the purpose of increasing production and income. The ability to basically conform to the above conditions is called “biological fertilizer†or “microbial fertilizerâ€, and not “fertilizer†containing “biological†or “microorganism†can be called “biological fertilizer†(or “microbial fertilizerâ€), even It is a great misunderstanding to call the general organic fertilizer "bio-fertilizer" or "microbial fertilizer", which should be noted.
　　
　　
Second, the technical source and technical background of the product should be clear. R & D background three to five years did not say how they actually cut the quality of how strong it is very worthy of study because the effect of microbial fertilizer inspection cycle is very long, there are many uncertain factors that may cause the product quality is difficult to cross the border, such as This batch of products is effective, and the effect of another batch of products may be discounted. This year's products are effective, and some of them will be inefficient or ineffective next year. Why is this happening? Because microbial fertilizer "core" - bacteria, it must continue to mention pure rejuvenation, once functional degradation, the effect is not. Therefore, only some of the more regulated manufacturers have the conditions to screen and purify and rejuvenate for a long time. This is one of the important reasons why the state has stipulated that the microbial fertilizer should be transferred from the temporary registration certificate to the official registration certificate.
　　
　　
Third, we must choose the brand to ring. Some technology can also be the product itself, but the brand name is either too vulgar to me "high tech" too obscure, too vulgar giving the "old fashioned" and other bad impression, too obscure people do not understand, get I don't understand, I don't understand what it means, and my desire to buy will be greatly reduced. What's more, in the era of “excessive economyâ€, there are many products, and under the same quality conditions, only one can understand, and the brand that is clear (including products and manuals, etc.) It’s good to sell. This is particularly important for sales agents, even a brand of all people can not read, hear no clear specification also makes "loving mind" products, which promote the dissemination of how hard is that you can make money ?
　　
　　
Fourth, to see whether there is negative media coverage, try not to choose products which have a negative reports, because "not hover fly eggs," because negative reports and more, certainly not accidental, its quality stability, vendor reputation, publicity There are estimated problems with promotion and other aspects, and those products should be avoided.
　　
　　
Of course, the correct choice of bio-fertilizer and microbial fertilizer brands can be clearly explained in a few words, both professional knowledge and experience accumulation. The following is a relatively long technical background, very stable quality performance of King Baby Fertilizer (the technology research and development unit has 70 years of research and development background) and its related products, interested parties may wish to compare with other products.
Sectional Door Accessories: motor 220V-380V, control box, spring break device, cable break device , aluminum alloy rope pulley, enhanced shaft bracket, air bag system, duplex enhanced guide wheel bracket.
Detail introduction for above main accessories
1.Motor and controller:
The garage door operator is designed for residential overhead sectional and tilt doors.
The operator memorizes the limit positions and unique braking system that slows the unit down at the end of its travel.
Rolling code remote control with max. 20 pcs hand transmitters.
The operator is equipped with a manual release lever which allows manual operation of the door in case of power failure.
The controller has a security LOCK function which prevents operation of the door from transmitter.
2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.
