种子发芽能力是播种品质中最重要的生物学特性,它决定种子是否适于播种,并决定播种量。发芽能力高的种子,出苗迅速整齐、幼苗健壮,种子的使用价值高,播种量就少。要确定种子的用价和播种量,除需进行发芽测定外,通常还要测定净度和千粒重。1959年“林业科技快根”发表的“重量发芽捡验法”,不需进行净度和干粒重测定,只测定一定重量的种子中,有发芽能力的种子数,并以此表示种子的使用价值。经过多年实践证明,这种方法减少
Seed germination ability is one of the most important biological characteristics of sowing quality, which determines whether the seed is suitable for sowing, and determine the sowing amount. High germination ability of the seeds, emergence quickly and tidy, robust seedlings, the use of high value of seeds, seeding quantity is less. To determine the cost of seeds and sowing, in addition to the need for germination determination, usually to determine the clarity and 1000-grain weight. In 1959, “Rapid Germination of Forestry Science and Technology” published “weight germination test method”, without the clarity and dry weight determination, only the determination of a certain weight of seeds, the number of germinating seeds, and as a seed Use value. After many years of practice, this method has been reduced
