中文摘要: |
对苦豆子破除种子硬实、提高活力指数的方法及最适发芽的土壤含水量和播深进行了测定与研究,结果表明:苦豆子种子发芽困难的原因是种皮致密,吸胀困难;提高发芽率的措施是砂纸摩擦或65%H2SO4处理20 min;提高种子活力的措施是65% H2SO4处理20 min后,再用0.02%GA3处理;苦豆子种子萌发的适宜土壤含水量为8%~12%,播种的最适深度是0~3 cm。 |
英文摘要: |
Sophora alopecuroides are important ecological grasses of the ecosystem in North China and the raw material for drug industry. The study were mainly about eliminating hard seed, the methods of improving seed vigor index, and the optimal soil moisture and sowing depth of seed germination. The results showed that the reason for the low rate of germination was that seed crust was too intensive. The measure of improving germinating rate was to scrap seeds with abrasive paper or to treat them with H2SO4(65%) for 20 minutes. In addition, the method of boosting seed vigor was to treat seeds with H2SO4(65%) for 20 minutes, then with GA3 (0.02%). For the seeds of Sophora alopecuroides, the optimal soil moisture was 8%~12% and optimal sowing depth was 0~3 cm. |
