解除树木种子休眠常用的方法,有以下几种。一、浸种:多数树木种子在播种前浸水,可提早萌发,特别是冬播种子延迟到春播更需浸种。池杉种子在播种前浸水2-3日,发芽所需日数由一个半月提早到7天,亩产量提高二倍以上;女贞种子干藏到来年4月播种,当年不能萌发,如浸水一周,几天就发芽,泡桐、楸树种子浸水48小时,可以提早萌发,而且出苗整齐;湿地松种子浸水10天,就能加速发芽。二、温度:采用低温、高温和变温处
Common methods of relieving the tree seed dormancy, there are the following. First, soaking seeds: most of the tree seeds soaked in the sowing, germination can be early, especially in winter sowing seeds to be delayed soaking need to be more. Seedlings of Ipomoea submerged 2-3 days before sowing, the number of days required for germination from one and a half months earlier to 7 days, more than doubled the yield per acre; seedless dried seeds to be planted in April next year, when the germination can not, such as a week, A few days to germination, Paulownia, Catalpa bungei seed soaked 48 hours, you can germinate early, and the emergence of neat; Slash pine seed soaking 10 days, you can accelerate the germination. Second, the temperature: the use of low temperature, high temperature and variable temperature
