种子包衣技术是一项低成本、高效益提高作物产量的实用技术。种子包衣不但能有效地预防病虫害,提高成苗率,而且种衣剂中含有的各种微肥、生化制剂,能给作物提供营养生长物质、激发酶的活性提高幼苗素质,促进作物生长。我州从1995年开始试验推广种衣剂,至今全州玉米种子包衣率已达100%。玉米包衣种子检验已成为种子检验工作中主要任务之一。按照常规种子检验方法检验包衣种子的发芽率,检验结果不稳定,结果偏低。我站种子质量检验中心经过5a的探索,总结出一套较为完善的玉米包衣种子发芽率检验技术,其检验结果准确,与大田种植出苗率一致。其主要技术环节如下:
Seed coating technology is a practical and cost-effective technique to increase crop yields. Seed coating not only can effectively prevent pests and diseases, improve seedling rate, and the seed coating contains a variety of fertilizer, biochemical agents, to provide crops with vegetative growth substances, stimulate enzyme activity to improve seedling quality, and promote crop growth. Since 1995, the state has been experimenting with the introduction of seed coating agents. Since then, the corn seed coating rate in the whole state has reached 100%. Corn coating seed testing has become one of the main tasks in seed testing. According to the conventional seed test method to test the germination rate of the coated seeds, the test results are not stable, the result is low. I stand seed quality inspection center after the exploration of 5a, summed up a relatively complete set of corn seed germination test techniques, the test results are accurate, and the emergence of field planting the same rate. The main technical aspects are as follows:
