皂角种皮革质不易吸水,播种后往往隔年发芽由于种子处理不当常常延续四年之久,不仅浪费种子,且不能完成任务。我国今年对皂角采取了用热水浸种,早期处理,随膨胀随播种,对于发芽效果很好,同时能节约大量种子,但是绝大多数种于在处理2—3个月仍不能膨胀,这就为完成任务造成困难,因此,于六月初用浓硫酸作试验,获得成功:试验材料:纯硫酸98% 种子为未吸水之硬粒。试验时间:6月1日17时。试验共分四组,其中一组为对照(见表1)

Gleditsia leather quality is not easy to absorb water, germination often occurs after sowing due to improper handling of seeds often extended for four years, not only waste the seeds, and can not complete the task. This year our country has adopted soaking saponins with hot water, early treatment, with the expansion with sowing, good for germination, while saving a lot of seeds, but the vast majority of species in the treatment of 2-3 months still can not expand, which As a result, difficulties were encountered in completing the task. Therefore, using concentrated sulfuric acid as a test was successful in early June. Test Materials: 98% of pure sulfuric acid was hard non-absorbent. Test time: at 17 o’clock on June 1. The test is divided into four groups, one of which is a control (see Table 1)
