温室黄瓜若干防污染方法研究初报

采用有机肥筛选,探索合理的施用方法及应用O3型紫外灯照射、黄板诱蚜和自然冷冻等物理新方法,对温室黄瓜病虫害进行试验、示范等防污染方法研究。结果表明,这些方法的应用,即不影响蔬菜的正常生长,又可以减少病虫害发生,降低化学农药和化肥使用量,极大地缓解了温室黄瓜有毒物质的残留和污染问题。

Research into Some Anti-pollution Methods for Greenhouse Cucumber

Anti-pollution methods for greenhouse cucumber are studied by means of filtering organic fertilizer to find out reasonable way of fertilization, making experiments by taking advantage of new physical methods such as irradiation with O3-type ultraviolet light, capturing aphid with yellow cardboard and natural freezing to prevent insect pests and plant diseases. Results show that, if applied in production, normal growth will not be affected on vegetable, but also the occurrence of insect pests and plant diseases can be decreased and the chemical pesticides and fertilizers can be reduced in quantity, which greatly help to resolve the problems of poisonous remainders on and pollution to greenhouse cucumber.
