农药的种类很多,除了有效成分含量较低的粉剂、颗粒剂和超低容量喷洒剂可直接施用外,其它有效成分含量较高的剂型,必须用稀释剂(如水、草木灰、细土等)稀释后,才可施用。由于不同规格和剂型的农药,施用浓度也不同。因此,正确掌握农药稀释的计算十分重要。现将农药稀释倍数和稀释浓度的计算方法简介如下,供参考。 There are many types of pesticides. In addition to the low active ingredients of powder, granules and ultra-low-volume spray can be applied directly, other formulations with higher active ingredient content, must be diluted with diluent (such as water, ash, fine soil, etc.) Before they can be applied. Due to different specifications and dosage forms of pesticides, the application concentration is also different. Therefore, the correct understanding of the calculation of pesticide dilution is very important. Now pesticide dilution times and dilution concentration calculation method is as follows, for reference.
