二、种子包衣剂的配制种衣剂的种类很多,但无论哪一种,都是用活性成分和非活性成分两大部分物质制成的。活性成分包括杀虫剂、杀菌剂、微肥、生物活剂等,是种衣剂中对作物起直接作用的成分,没有它们,种衣剂就失去了使用价值,它们的不同,也决定了种衣剂的不同类别和用途。非活性成分包括成膜剂、缓释剂、界面活性剂、悬浮剂、保水剂、酸度调节剂、防冻剂、防腐剂、警戒色等系列化学配套助剂。它们本身对作物不起直接作用,但能改变种衣剂的理化性质,保证种衣剂有较好的成膜性、稳定性和缓释性,对种子安全而对
Second, the preparation of seed coating species There are many types of seed coating, but no matter what kind of active ingredients are used and inactive ingredients made of two major components. Active ingredients, including insecticides, fungicides, trace fertilizers, bioactive agents, are the components of the seed coat that act directly on the crop, without them, the seed coating loses its value, and their differences also determine Different types and uses of seed coating. Inactive ingredients include filming agents, release agents, surfactants, suspending agents, water retention agents, acidity regulators, antifreeze, preservatives, warning colors and other chemical additives. They themselves can not play a direct role in crops, but can change the physical and chemical properties of seed coating, seed coating to ensure better film formation, stability and sustained-release,
