肥水是我国劳动人民在长期生产斗争中发现的一种含有相当数量硝态氮的地下水,也是一种天然的地下肥源.为了从增产效果来评价肥水的开采价值和效果,一般把每方水含有硝态氮15克(即15PPM)以上的地下水定为肥水. “水利是农业的命脉”,“肥料是植物的粮食”.用肥水灌溉,既得水,又得肥,使作物肥水兼得,显著增产.据调查,一般可增产20%以上,有的甚至成倍增产.这是因为 Fertilizer water is a type of natural underground fertilizers that is found in the long-term production struggle by our working people in the form of groundwater containing a considerable amount of nitrate nitrogen. In order to evaluate the value and effectiveness of fertilizing water from the stimulation effect, Groundwater containing more than 15 grams of nitrate (ie, 15 PPM) is defined as fertilizer, “water is the lifeblood of agriculture,” and “fertilizer is the food of plants.” Irrigating with fertilizers yields both water and fertilizers, Significant increase in production.According to the survey, the general increase of more than 20%, and some even doubled production.This is because
