It indicates that the compound amino acid chelated mineral elements fertilizer has the characteristic of little quantities,low cost,high rate of repay, not only being able to raise the output of crops,to improve qualites,but also being able to kill baotera and insects,to remove weeds and to decrease the effect of residual pesticide and that it is a new type of fertilizer which has unlimited possiblities.
Based on the comparison of fertilization rates among China and other countries, and the tendency in diminishing fertilizer consumption in developed countries, an investment inclination to the path of "new fertilizer research and development-industrialization-commercialization" is proposed, aiming at China's secure food supply and sustainable economy growth in the future 30 years under the condition of a slow fertilization increase or even cease.
In present paper, in order to make a new way to use chitosan and to develop a new fertilizer, chitosan which came from abandoned chitin, was used as main material to coat compound fertilizer and we produced seven different treatments coated compound fertilizers.
Fertilizer industry develops steadily in the 21th century at the proper proportion of NPK. Development of special fertilizers,especially of new type fertilizers in accordance with demand law of crops will become a new trend. Guided by market consumption, we′ll develop in the directions of multi-functions, multi-products, multi-industrials and export-oriented enterprises.
The optimal synthesis process of oxidized starch adhesive and the significant factors to the viscosity of the adhesive were determined by means of orthogonal design. At the same time,the adhesive stability, the adhesive bio-toxicity,and its application in new type fertilizers also were studied.
Many innovations, such as the introduction of a new fertilizer by a farmer, or the use of a new raw material by a manufacturer, or the adoption of a new hairstyle by a lady of fashion, can be tested on a 'try-before-buy' basis.
