在日本,夏季苹果园的喷药量一般是每1公顷500升。在欧美每1公顷的喷药量为30～100升,将药液浓度提高5～10倍,称为低容量喷布法或浓缩喷布法,而将每1公顷喷药量500升的称为高容量喷布法或稀释喷布法。低容量喷布法是农药喷洒技术的一种新发展,即将单位面积的喷药量减到1/5～1/10,而将药液浓度提高
In Japan, summer apple orchards are sprayed at 500 liters per hectare. In Europe and the United States every 1 hectare spray volume of 30 to 100 liters, the liquid concentration increased by 5 to 10 times, known as the low-volume distribution method or concentrated distribution method, and the spray of 500 hectoliters per hectare said For high-volume method of spraying or dilution method. Low-volume sprinkling method is a new development of pesticide spraying technology, that is, the amount of spraying per unit area is reduced to 1/5 ~ 1/10, while the liquid concentration increased
