Yan Xuan Zhang, chairman of our national invention patent "a predatory mite - Amblyseius cucumeris a
Predatory mites were the effective enemies of the orchard, farmland, forest pest mites and small pests.. The traditional production of predatory mites method is using plant pollen or planting crops breeding red spider reproduction of predatory mites, high cost of production, flower industry university, cycle is long, pollen, leaves of perishable rotten is not easy to storage and transport. The cost of using predatory mites to prevent and control the pests and mites is 10-20 times of the conventional anti pest mites, so it is unable to form a wide range of applications.. The patent inventor Yan Xuan Zhang, after 20 years of research and development, and in 1997 in China was developed with independent intellectual property rights of the predacious mite - Cucumber Amblyseius mite factory production technology and process flow. 2005 national invention patent authorization (ZL02110907.9). The invention solves the problem that the mites factory production problem in China for 50 years, and develops the field of the predatory mites industry in China, and provides a successful example for other natural enemies factory production in China..
By comparing with the patent for the production of predatory mites: low cost, short production cycle, the annual production capacity is higher than that of the traditional 1500--2000 times, the application range is wider than foreign products, control effect of higher by 10 percentage points, price only for foreign products 1 / 5 to 5 - 1 / 45, field application cost only 30-50% of the conventional chemical control, can reduce pesticide use 40% - 60%. This patent makes the dream of the several generations that the predatory mite can provide at the time of production as the dream of a few generations, become the first of our countrys farmers to use natural enemies commodities. 2008 - so far 200 batches (2000000000) predatory mites exported to Holland, Germany, Canada, the United States and other countries, the end of the history of Chinas natural enemies can not export commodities.
Industry experts on the evaluation of the patent:
(1), Chinese Academy of Sciences Academician Guo Yuyuan in 2007-2008 the subject of plant protection development report: "Plant Protection Research Institute, Fujian Academy of Agricultural Sciences developed successful Amblyseius commodity and application in prevention and cure of bamboo, citrus, cotton, chestnut, etc. crop pest mite, and promote the Chinas predatory mites the. This study provides an excellent natural enemy lines for Chinas control of pest mite, also made a successful attempt for nutrient acclimation enemies; (2), Nanjing Agricultural University professor Hong Xiaoyue editor of "agricultural acarology" (the "eleven five" in agriculture and forestry universities standardized materials) wrote: 1997 Fujian Provincial Academy of agricultural Sciences Institute of plant protection researcher Zhang Yanxuan successfully suited to Chinas national conditions with independent intellectual property rights of Amblyseius cucumeris artificial feeding method and process and obtained the national invention patent, solves the problem of product packaging, refrigeration and transportation and other technical problems, and to develop and improve a set of application of a.cucumeris based on mite mite biological control technology. A.cucumeris factory production for other predatory mites and pointed out the direction in the development and application of China.
The results of this patent
After 10 years of efforts have been completed and is currently Asia first largest collection of scientific research, development, demonstration, promotion, achievements, industrialization, predation mite commercialization, natural enemy products after-sales service for one annual production capacity of up to 8000 million of the predatory mite commodity production base. Yan Xuan Zhang presided over the predacious mite products and forestry harmful mite biological control matching technology research and application "(the patent technology as the core) won the 2008 annual national scientific and technological progress second prize, 2007 Chinas agriculture, the highest award - the agricultural science and technology award second prize. The patent law to produce the predacious mite products obtained "national key new product", "Fujian Province independent innovation products", "Yan Xuan technology" brand predator mite won the 16th China Yangling Agricultural happy science and Technology Fair "Houji Award". "Amblyseius" in 2012, 2013, the second was awarded the National Agricultural Technology Extension and service center, "I trust the prevention and control of green brand products".
The contribution of this patent to society is reflected in the following aspects:
1, the end of the history of the predacious mite factory cannot production, natural enemies in the field of industrial development, and fills the domestic gap of the R & D, the predatory mites in China become the first farmer of natural enemy products:
2, the implementation of the patent has a remarkable economic, social, ecological benefits, lead and promote the rapid development of pest and pest control technology in China:
