莱阳市是全国最大的蔬菜基地之一,黄瓜栽培面积较大。目前,对黄瓜病虫害仍以化学防治为主,农药使用量大,用药次数多。加之部分菜农滥用农药,造成农药残留量严重超标。因此,实施黄瓜无公害栽培,既要减少化学农药用量,保护生态环境,又要保证蔬菜产品的农药残留量不超过国家规定标准。现将黄瓜无公害综合防治技术总结如下: 一、农业防治措施农业防治是黄瓜无公害生产技术的基础。应用各种农业防治措施,可以创造出有利于黄瓜生长的生态环境条件和不利于病虫发生危害的条件,能够增强植株的抗性,从而控制和减轻病虫危害。 (一)采用抗(耐)病品种适宜莱阳市推广的农艺性状好的抗(耐)病品种主要有 Laiyang City is one of the largest vegetable bases in the country with a large cucumber cultivation area. At present, the cucumber pests and diseases are still dominated by chemical control, pesticide use, medication frequency. In addition, some vegetable farmers abuse pesticides, resulting in serious excessive pesticide residues. Therefore, the implementation of pollution-free cucumber cultivation, it is necessary to reduce the amount of chemical pesticides to protect the ecological environment, but also to ensure that pesticide residues in vegetable products does not exceed the national standard. Now cucumber pollution-free comprehensive prevention and control technology is summarized as follows: First, agricultural control measures Agricultural control is the basis of pollution-free cucumber production technology. The application of various agricultural control measures can create eco-environmental conditions conducive to the growth of cucumbers and conditions that are detrimental to the occurrence of pests and diseases, and can enhance plant resistance so as to control and reduce pests and diseases. (A) The use of resistant (resistant) varieties suitable Laiyang City to promote good agronomic traits resistant varieties are
