种子纯度是种子质量的一项重要指标。为考核各基地的种子质量,验证田间纯度检验的准确性,我市在坚持多年田间小区种植检验或海南鉴定的同时,又在种苗鉴定室进行纯度鉴定的尝试,收到良好效果,为控制劣种下地,在种子下拨前消除隐患起到重要作用。其主要方法是:1.发芽床准备:试验采用锯沫床,经反复试验证明,锯沫床试验结果与国家规定的砂床相比,不超允许误差,且具有保温、保湿、通透性好、操作简便、成本低廉和发芽速度快等明显优点。事先将每个锯沫箱中的锯沫刮平,以尺压沟,行距4厘米左右,深度1.5～2.0
Seed purity is an important indicator of seed quality. In order to assess the seed quality of each base to verify the accuracy of the field purity test, the city adhere to many years of field planting test or Hainan identification at the same time, in the seed chamber identification purity of the attempt to receive good results for the control Inferior species, to eliminate hidden dangers played an important role in the seed before dialing. The main method is: 1. Germination bed preparation: The test saw saw bed, after repeated tests proved that sawing bed test results compared with the national provisions of the sand bed, not exceeding the allowable error, and with heat, moisture, permeability Good, easy to operate, low cost and sprouting speed and other obvious advantages. Prior to each saw foam box scrape the scraping, with a pressure groove, spacing of about 4 cm, a depth of 1.5 to 2.0
