一、对国內現有人力药械的分析 当前广大农村普遍使用的人力药械,如单管噴霧器、压縮式噴霧器、手搖噴粉器等,一般看来噴药貭量較差,生产效率較低。在一般的噴量下,噴霧生产效率为10亩/人·日左右,噴粉生产效率为15亩/人·日左右。在羣众性的工具改革运动中,各地对于药械作了很多的改进,河南新乡七里营改装的单管喷霧器(見图1),两人一天可噴25亩棉花;很多地方将单管噴霧器改装在手推車上(图2),提高效率2～3倍;上海农业药械厂出产的双輪
First, the analysis of the existing domestic manpower and machinery At present, the widespread use of human medical equipment in rural areas, such as single-tube sprayer, compressed sprayer, hand duster and so on, generally appear to weigh less spray, lower production efficiency. In the general spray volume, spray production efficiency of 10 acres / person · day or so, dusting production efficiency of 15 acres / person · day or so. In mass movement of the tool reform, a lot of improvements were made to the medical equipment throughout the country. The single tube sprayer modified by Qiliying in Xinxiang, Henan Province (see Figure 1) can spray 25 acres of cotton a day; in many places, Sprayer modified trolley (Figure 2), to improve efficiency of 2 to 3 times; Shanghai Agricultural Machinery Factory produced double
