We Investigated the species of diseases and insect pests, species of natural enemies, distribution and dominant species in export vegetable bases in Shandong Province. Dynamics of main diseases and insect pests were studied.2. We investigated the main control technologies for diseases and insect pests, types and application methods of pesticides.3. Effects of crop varieties, fertilities and cultivation on diseases and insect pests, production and pesticide residues were examined.4. Control effects and application technologies of frequency trembler grid lamps, greenhouse ozone machine and insect-proof net were tested.5. By research, seven biological preparations and twelve chemical pesticides with high activity, low toxicity and low residue were screened.

Genetic diversity among 7 populations of Trillium tschonoskii were analyzed by using inter SSR and amplified fragment length polymorphism molecular markers. The results were as follows:(1)ISSR: 12 out of the 100 primers showed consistent banding patterns and amplification, a total of 135 bands were produced with an arrange of 250-2500bp, 46 of which (34.07%) were polymorphic.

应用锚定SSR和限制性片段多态对7个延龄草居群的遗传多样性进行了分析，结果如下：从100个引物中筛选出12个ISSR引物，在250-2500bp之间共扩增出的135个条带，其中多态性带为46，占34.07％。
