有些种子发芽比较困难,发芽率低,但对不同的种子,经过技术处理,可提高发芽率。1.菠菜菠菜种子难发芽的主要原因是种皮较厚、较硬、透气性差,影响其吸水、膨胀,以及营养物质的转化,造成种子处于休眠状态而不发芽。具体处理如下:试验表明,经碾压且变温处理,发芽率可 Some seeds germination more difficult, the germination rate is low, but for different seeds, after technical treatment, can increase the germination rate. 1. spinach Seeds difficult to sprout germination is the main reason is thicker seed coat, harder, poor air permeability, affecting its water absorption, swelling, and nutrient conversion, resulting in the seeds in a dormant state without germination. The specific treatment is as follows: Tests show that, after rolling and variable temperature treatment, germination rate can be
