我们在苦楝育苗过程中了解到由于苦楝果核坚硬,播种后分化时间长,种子发芽出土迟,苗木生长期短,影响高、粗生长。为了提高苦楝苗的质量,我们于一九六九年进行了隔年苦楝子(果核经一年时间沙藏)育苗试验。结果隔年种子比当年种子提早出土近一个月,种子发芽整齐,苗木生长均匀。
In the process of nurturing seedlings, we learned that due to the firmness of Melia tomentosa nuclei, long time of differentiation after sowing, delayed emergence of germinated seeds, short seedling growth period, high influence and coarse growth. In order to improve the quality of Neem seedlings, we carried out the nursery trials in 1989 with the annual nectarine (fruit core after one year of sand storage). As a result, the seeds of the second year were unearthed earlier than the current year for nearly a month, the seeds germinated and the seedlings grew evenly.
