制定的原则 1.技术指标必须科学,能充分反映该种类的质量水平。如花卉种子以净度、发芽率、含水量、每克种子的粒数来确定花卉种子的质量等级;花卉种苗以地径、苗高、叶片数、根系状况等指标来衡量种苗的质量高低;种球以围径、饱满度等来确定种球的质量等级。 2.确定等级必须简洁,具可操作性。由于一个种
Principles developed 1. Technical indicators must be scientific and can fully reflect the quality level of the species. Such as flower seeds with clarity, germination rate, water content, grain number per gram of seeds to determine the quality level of flower seeds; flower seedlings in diameter, height, leaf number, root system status and other indicators to measure the quality of seedlings High and low; kind of ball to the radius, fullness, etc. to determine the quality of the ball. 2. To determine the level must be concise, practical. Because of one species
