波尔多液是由硫酸铜和石灰乳配制而成,主要成份是碱式硫酸铜。由于不同果树对石灰及铜元素的敏感程度不同,必须科学使用才能取得最佳效果。一、正确配制比例波尔多液配制时把水用量分成两等份,一份水用于溶解硫酸铜,一份用于调配石灰乳,待硫酸铜充分溶解后,再将硫酸铜溶液缓缓倒入石灰乳中并随即搅匀,即可配成悬浮性最好的波尔多液;波尔多液的配制形式有等量式、半量式和倍量式等,其硫酸铜与生石灰之比分别为1:1,1:0.5和1:2,水可按需要增 Bordeaux mixture is made of copper sulfate and lime milk, the main ingredient is basic copper sulfate. Because different fruit trees are sensitive to lime and copper, they must be used scientifically for best results. First, the correct preparation of the proportion of Bordeaux mixture when the amount of water is divided into two equal parts, a water for the dissolution of copper sulfate, one for the deployment of lime milk until the copper sulfate fully dissolved, and then pour slowly copper sulfate solution Lime milk and then stir evenly, you can dubbed the best suspension of Bordeaux mixture; Bordeaux mixture of the preparation of the same amount, half-amount and double-fold, etc., the ratio of copper sulfate and quicklime were 1: 1 , 1: 0.5 and 1: 2, water can be increased as needed
