化学肥料与农家肥料配合起来,合理施用,增产效果是显著的。但是化学肥料容易挥发、淋失,施用不当,一部分肥力浪费了。这个问题,往往被人忽视,如果每个生产队都作一番调查研究,都会发现这种浪费,有的还可能是严重的。因此,怎样避免或减少它在运输、贮存和施用时的损失,已经成为一个必须注意的问题了。本文先就怎样合理施用化肥的问题,把各地的经验作一扼要介绍。一、氮肥施用技术我国生产和施用的氮肥,主要有碳酸氢铵、氨水、尿素、硝酸铵、硫酸铵、氯化铵等几种。以碳酸氢铵
Chemical fertilizers and farm manure together, the rational application of increased yield effect is significant. However, chemical fertilizers are easily volatile, leaching, improper application, part of the fertility wasted. This problem is often overlooked. If every production team conducts some investigation and study, it will find such waste and some may be serious. Therefore, how to avoid or reduce its loss in transportation, storage and application has become a problem that must be noticed. This paper first on how to rationalize the issue of fertilizer, to make a brief introduction of experiences around. First, the application of nitrogen fertilizer production and application of nitrogen fertilizer in our country, mainly ammonium bicarbonate, ammonia, urea, ammonium nitrate, ammonium sulfate, ammonium chloride and several other. Take ammonium bicarbonate
