颗粒肥料简称粒肥,按照它的性质来说可以分为两种,一种是颗粒状的无机肥料如过磷酸钙,另一种是用有机肥料(城市垃圾、廐肥、牛粪、羊粪、泥炭、干的家禽粪等)与无机肥料(过磷酸钙、硫酸铵等)混合制成颗粒的形态,其颗粒的大小约有4市分,呈结实的团粒形状,也就是大小约相同的园形颗粒。在干燥状态时,它不带有粉末,而当空气湿润时也不会粘结成块状。由于它含肥丰富且施用便利,许多农民又称它“果子肥”。把肥料制成颗粒来用,是苏联科学的先进成就,也是合理用肥、集中用肥和提高肥效的最好办法。茲将几项主要制造技术及其施用方法介绍如下:
Granular fertilizer referred to as granular fertilizer, according to its nature can be divided into two kinds, one is granular inorganic fertilizers such as superphosphate, the other is the use of organic fertilizer (municipal waste, fertilizer, cow dung, sheep manure, Peat, dried poultry manure, etc.) and inorganic fertilizers (such as superphosphate, ammonium sulfate, etc.) into the form of particles, the size of the particles of about 4 sub-city, was the shape of a solid aggregate, which is about the same size of the park Shaped particles. It is dry with no powder and does not stick to the block when the air is wet. Because of its abundance and ease of use, many farmers also call it “fruit fat.” The use of fertilizers to make grains is an advanced scientific achievement of the Soviet Union and the best way to rationally use fertilizer, concentrate fertilizer and improve fertilizer efficiency. Here are a few key manufacturing techniques and their application methods as follows:
