波尔多液是由硫酸铜、石灰、水混合而成的天蓝色略有黏稠性的保护杀菌剂,它保护性能好,使用范围广。硫酸铜和石灰的比例分为石灰等量式(1:1)、半量式(1:0.5)、倍量式(1:2)、多量式(1:3~5)。倍数指硫酸铜与水的比例,如200倍,就是200份水中有l份硫酸铜。生产中,常用两者的结合表示波尔多液的配合 Bordeaux mixture of copper sulphate, lime, water, a little blue sky viscous protective fungicide, it is a good protective performance, the use of a wide range. The ratio of copper sulfate to lime is divided into lime equivalent (1: 1), half (1: 0.5), double (1: 2) and multiple (1: 3-5). Multiple refers to the ratio of copper sulfate and water, such as 200 times, that is 200 parts of water l parts of copper sulfate. Production, the combination of both commonly used Bordeaux mixture said
