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.

Gray., ect. are found to meet the first-class organic manure standard; 40 species such as Eupatorium odoratum L., Eupatorium catarium Veldkamp., Eupatorium adenophorum Spreng., Conyza canadensis L. etc met second-class organic manure standard; 4 species such as Ageratum conyzoides L., Blumea balsamiferae DC., Conyza japonica Less., Centipeda minima L.

常见的革命菜、一点红、苦菜、地胆草和鬼针草5种菊科野菜，其营养价值可与栽培蔬菜媲美，部分种类野菜的营养成分含量甚至超过栽培蔬菜：革命菜、一点红、苦菜和鬼针草的粗蛋白含量均超过栽培的茼蒿，粗纤维含量与茼蒿及白菜中含量接近；5种野菜的维生素C含量均高于白菜。

NO3--N pollution in drinking water at the depth of 20 m is serious with common and serious overproof rates of 39.3% and 7.1% respectively. NO3--N content in irrigation water for farmland and greenhouse at the depth of 40 m is 7.4 mg·L-1 and 9.6 mg·L-1 with respective common overproof rates of 25.0% and 37.5%, and zero serious overproof rate.

设施蔬菜栽培区表层地下水(地下饮用水， 20 m)受硝态氮污染严重，超标率和严重超标率为39.3%和7.1%；而深层地下水(农田和大棚灌溉水， 40 m)硝态氮含量7.4 mg·L-1和9.6 mg·L-1，超标率分别为25.0%和37.5%，无严重超标水样。

NO3(superscript -)-N pollution in drinking water at the depth of 20 m is serious with common and serious overproof rates of 39.3% and 7.1% respectively. NO3(superscritp -)-N content in irrigation water for farmland and greenhouse at the depth of 40 m is 7.4 mgL^(-1) and 9.6 mgL^(-1) with respective common overproof rates of 25.0% and 37.5%, and zero serious overproof rate.
