山楂种子因种壳胶质厚且比较坚硬,所以砂藏处理时间较长,一般需240天左右,为缩短时间可采取以下方法: 1、变温处理将采集的种子用开水烫至冷却,再浸泡24小时,然后在太阳下暴晒4—5小时。如此重复三次,水依次用开水、温水、一般温度的水。这样经反复浸晒就有部分种子破壳,然后再行沙藏。 2、早采砂藏在9月中下旬采收时,种仁巳基本成熟但壳尚来硬化。采果后立即砂藏(种子和砂的比例可按1:5),第二年春经过催芽即可播种。 3、机械碾压将山楂种子铺在碾盘上,可略厚些,随碾随筛,清除种皮和混杂物,再砂藏,第二年 Hawthorn seeds because of the shell plastic thick and relatively hard, so the sand reservoir processing time is longer, usually takes about 240 days, to shorten the time can take the following methods: 1, temperature treatment will be collected seeds with boiling water to cool, and then soaked 24 hours, then 4-5 hours in the sun. So repeated three times, water followed by boiling water, warm water, the general temperature of the water. After repeated immersion in this way, some seeds are broken and then re-sand reservoir. 2, early mining sand storage in late September harvest, the seeds have been basically mature but the shell is still hardened. Sand storage immediately after picking fruit (seed and sand ratio can be 1: 5), the second spring after germination can be sown. 3, mechanical rolling shop hawthorn seeds in the pan can be slightly thicker, with the grind with the sieve, clear the seed coat and hybrids, then sand reservoir, the second year
