How to deal with the seeds of plants, flowers and trees before sowing

In general, the seeds of plants, flowers and trees can be sown directly without any treatment. Seeds with oil and wax in the outer shell can be mixed with plant ash and water into a paste before sowing; seeds with a hard coat need to bruise the seed coat and soak in warm water for 24 hours before sowing; some seeds need to be sowed before winter, when the shell is frozen and cracked, it can germinate the following spring. For the seeds of plants, flowers and trees with thick seed coat, it is generally necessary to accelerate germination before spring sowing, and two methods are often used to accelerate germination:

1. Water immersion germination: can be divided into three kinds of water temperature treatment, cold water soaking seeds (above 0 degrees Celsius), warm water soaking seeds (40-60 degrees Celsius), hot water soaking seeds (70-90 degrees Celsius).

two。 Stratified sprouting: refrigerate with three parts of wet sand and one part of the seeds of plants, flowers and trees. In addition, the seeds of long-term dormant plants, flowers and trees or seeds sprouting every other year can be accelerated by variable temperature, that is, after soaking seeds, the temperature is kept at 25-30 degrees Celsius during the day and 15 degrees Celsius at night, repeated for 10-20 days, it can promote its germination.
