一我们过去所常用的方法我们过去稀释石灰硫黄液所常用的方法是:1.先用波美比重计测定原液的浓度,设为波美25度。2其次,检查稀释表,如果所需要的喷射浓度是波美0.5度,那么从两种浓度交叉的一格得知,需加水59倍(实际应为59.2118倍,详后)。由此可见,要稀释石灰硫黄液备用,必须同时具备:1.波美比重计,2.稀释倍数表,两者缺一不可。由于波美比重计的不普遍,所以过去在农业科学通讯
A method we used in the past We used to dilute the lime sulfur liquid commonly used method is: 1. First Baume gravimetric determination of the concentration of the original solution, set Baume 25 degrees. 2 Second, check the dilution table. If the required spray concentration is 0.5% Baume, then add 59 times more water (59.2118 times, in more detail) from the cross of the two concentrations. Thus, to dilute the lime sulfur liquid spare, must also have: 1 Baume, 2 dilution multiple tables, both indispensable. Due to the fact that Baume and Pique are not commonplace, they used to be in scientific communication in agriculture
