喷药(液态)作业时,田间加水是必要的辅助工作。多年来一直感到加水耽误的时间太多。为此我们今年改自流加水为气压加水。自流加水时,每次加600升水,至少需要10多分种。如果水罐车停的位置较低,就会剩一部分水加不进喷药机的液箱里,最多时会剩下半罐水。采用气压加水后,同样加600升水,只需3.5分钟,效率提高两倍多。这是利用铁牛-55拖拉机的空气压缩机(其泵气量较小)所获得的结果,如果采用其它车型的大容量空气压缩机,水罐能承受更大的压力,则加水
Spraying (liquid) operation, field water is necessary to assist work. Over the years I have been feeling too much time on water. For this reason we changed from this year to add water for the pressure of water. When adding water, add 600 liters of water each time, at least more than 10 sub-species. If the water tank car parked at a lower position, the remaining part of the water will not enter the tank of the spraying machine, and at most half of the tank water will remain. With pressure plus water, the same increase of 600 liters of water, just 3.5 minutes, more than double the efficiency. This is the result of using an air compressor (with a smaller pumping capacity) of the Tractor-55 tractor. If large-capacity air compressors of other models are used and the tank can withstand more pressure, then water
