实践证明,搞好种子处理,是促进蔬菜早熟高产,提高经济效益的重要技术和关键性措施,现介绍几种种子处理的方法,供菜农参考。一、低温或变温处理法先把蔬菜种子用温水浸泡催芽,当种子见芽萌动时,置于0℃左右的条件下5～7天,或12小时,再移到15～20℃的中温条件下12小时,这样交替处理7天左右便可。种子经过上述处理后,能大大提高幼苗抗坏血酸和干物质的含量,加速叶绿素的合成,增强其抗寒能力,对促进蔬菜早熟高产效果特显。
Practice has proved that doing a good job of seed treatment is an important technology and key measure to promote high yield of vegetables and improve economic efficiency. Now we introduce several methods of seed treatment for vegetable farmers’ reference. First, the low temperature or variable temperature method First vegetable seeds soaked with warm water sprouting, see germination of seed germination, placed at 0 ℃ for about 5 to 7 days, or 12 hours, and then moved to 15 ~ 20 ℃ in the temperature conditions Under the 12 hours, so alternating for about 7 days can be. Seeds after the above treatment, can greatly improve the seedlings of ascorbic acid and dry matter content, accelerate the synthesis of chlorophyll and enhance their ability to resist cold, to promote the effect of early maturity and high yield of vegetables is obvious.
