编辑同志 :现在 ,各种农药的用量说明都是以克、毫升为单位的 ,农民每家每户土地面积不同 ,用药量也不一样 ,且每次用药量较小。由于农民手中没有天平和量杯 ,农村市场又买不到 ,很难从大包装农药中称出几克药粉或量出几毫升药液 ,大都是凭经验估计用药 ,用量当然不会准确。结 Edit Comrades: Now, the dosage of various pesticides are described in grams and milliliters. Each farmer has different land areas per household, and the dosage is different, and each dose is smaller. As farmers do not have the balance and measuring cup, the rural market can not buy, it is difficult to weigh a few grams of powder from the bulk of pesticides or measure a few milliliters of liquid, mostly based on empirical estimates of medication, of course, the amount will not be accurate.
