The planting process of seeds
To sow seeds, first sow the seeds in the soil and cover them with fine soil. Only a thin layer is needed to cover the seeds. The seedlings emerged, and the seedlings soon grew out. Transplant, transplant the seedlings into flowerpots and watch them as potted plants. Topping, in order to promote branching, when the leaves grow to 4-6 leaves, pinch off the top. When new branches grow, the branches of the seedlings begin to increase and grow into pieces of leaves. This is the success of planting!
What are the self-conditions for seed germination?
1. An embryo with integrity and vitality.
Seeds that have been bitten by insects cannot germinate. After leaving the mother, the seed will lose its vitality for more than a certain period of time and cannot germinate, and the life span of different seeds is different. For example, willow seeds last only 12 hours, peanuts for one year, wheat and rice for 3 years, cabbage and broad beans for 5-6 years.
two。 Have an adequate nutritional reserve
Normal seeds store enough nutrients for seed germination in cotyledons or endosperm, but shriveled seeds often fail to germinate due to lack of adequate nutrients.
3. Not in a dormant state
After most seeds are formed, they cannot germinate temporarily even under suitable conditions. This phenomenon is called dormancy.
