Product Description
At present, our country chemical fertilizer's annual output had achieved 150 million tons, urea occupies above 1/5. After the urea executes into the soil, can decompose and release out nitrogen under the urine enzyme's function. But the urea solubility is big, can drain along with the moisture content in soil; In addition, also a part of urea may adhere to the soil pellet surface layer so that difficult to be absorbed by the crops. Thus, causes the urea's effective availability generally isonly about30%. Therefore, the various countries was trying to find out the method f how to raise the urea use factor. At the end of 40's last century, the researcher discovered the urea and the formaldehyde's condensation product releases the ammonia obviously is lower than the urea, and has carried on the experiment in the American pasture, confirmed this kind of condensation compound has the good fertilizer effectiveness. Thus, many countries then start to take as the slow-releasing chemical fertilizer to conduct the experimental study. In recent years according to the reports from Japan, Germany and so on, this kind of condensation compound also had the functions of promo-ting soil to form the granular structure, guaranteeing the soil moisture, preventing desertification and increasing crops root system penetrating power.
At the same time also has characteristic, for example, environmental prote-ction, resources economization, and labor force economi-zation. The composition of formaldehyde urea cannot cause the burn and the leaching loss, can release the majority of nitrogen gradually in the entire growth season, other parts possibly change over to the next growth season. Compared with solvable fertilizer, urea formaldehyde's release nitrogen speed is slower, but we have to know that most of the urea formaldehyde do not use seperately. They always mix with dissolved nitrogen and mixed ferti-lizer for which has phosphorus and kalium components.
The solvable fertilizer provide early period nutrient, me-anwhile, the urea formaldehyde gives and effect to prolong the efficiency. The union of the soluble nitrogenous ferti-lizer and the urea formaldehyde's only result is to btain the nitrogenous fertilizer of which is evenly and can leng-then the releasing time, Pledge enough nitrogen within a certain long period. Products of UF of our company are produced accord-ing to the quality levels ofU. S. A. And Japan, which reaches the advanced international standards Out companycanprovide Urea for maldehyde.
Hubei Yufeng Biological Engineering Co., Ltd set up in the year 2000. It is a high-tech private-owned corporation that doing research on the Chitin and further give it manufactured and sold. The company located in the high-tech industry zone of Zhuankou Economic Development Zone. The company has 5 staff that are professors, doctors and senior engineers respectively, 58%of the men are above college academic level. The research is mainly based on the Life Sciences College of Hubei University and the Chitin Research Center of Wuhan University. Our main product is the " hemicellulose substrated chitosan oligosaccharide", which gained us 900 thousand Yuan that provided by the Science and Technology Office for supporting the medium-sized Corporation innovation.
This product gained a invention patent and a new practicality patent. More significant, the project has been passed and authorized by the Science and Technology Office as a Torch Plan Project in 2003(2003EB021128). In April, 2003, the company passed the examination of quality ISO9001: 2000. Now we have the ability to product 50 tons of chitosan oligosaccharide per year, which owns the first place of the nation and the best quality as well. "Li erqing" Capsule is one of our product that makes use of the chitosan.
Our further plan is to develop and make full use of the chitosan oligosaccharide in the area such as health care production, water disposal, agriculture fertilizer and so on. Also to extend and expand the export of the chitosan oligosaccharide product is the main point.
