Research On Dynamic And Control Technology Of The Main Pests For Environment-friendly Wolfberry In Ningxia

This text regarded important economic crops wolfberry (Lycium barbarian L.var. Ning-qi I), of Ningxia as the research object, based on domestic and international environment-friendly food standard and set up environment-friendly wolfberry and standardizing the technology system of production . Investigated the number of wolfberry's main insect pests and natural enemies in different culture district and extent of injury in Ningxia , found out the main pests annual growth and dynamic under different, wolfberry main producing region of Ningxia , selected the different of environment-friendly pesticides that suitable for the wolfberry grows and pests, made prevention and control technology and tactics for wolfberry. They are provided technological basis and practise the foundation for wolfberry development. The result shown :1) Wolfberry aphid , wolfberry plant louse , wolfberry pest mite are main pests in Guyuan, Zhonging , Yinchuan and Huinong which wolfberry main producing region, there are obvious differences between its quantity happed and time happed. It is very general that the aphid happed, the heaviest areas among them is Yinchuan , Huinong county and Zhongning county, Zhongning county seriously happed in the whole year, the peak happed 6 times to accumulate in the whole year, secondly it is Yinchuan; the most quantity of plant louse was Guyuan , present 2-3 peak periods in the whole year, including the beginning of August and mid-September .secondly it was take place light relatively in Huinong,and in Zhongning than Yinchuan; mite is the most appear in Yinchuan and Guyuan, it accumulate appear peak period of 6 times, secondly it is Huinong and in Zhongning.2) Selected and tested 11 kinds pesticides that include mineral source, plant source and high-efficient low toxicity, defined imidacloprid, matrine and sulfur and mixted produce as main pesticides that prevented and controlled for environment-friendly wolfberry production.3) Demonstrated, practiced and make good result that combine pests take place reality with locality t experience in Guyuan, Zhongning, Yinchuan and Huinong, and make pests control tactics for Guyuan, Zhongning, Yinchuan and Huinong.4) Made and implemented 3 kinds of modes that no chemical pesticides, reduce chemical pesticides (reduce 50% and reduce70% ) that provide the technological basis for green food and organic food production.This research provide technical support for "plan of environment-friendly wolfberry" in Ningxia. It provide technical support of standardize technology system for environment-friendly wolfberry production.
