Germination is a key measure to ensure the rapid emergence and full emergence of pepper after sowing. Nowadays, in the process of pepper planting, pepper seeds need to be properly germinated, and this is also one of the secrets of stable and high yield of pepper.
So when is it good for pepper seeds to germinate? What are the germination methods? Let's find out:
1. When is it good to germinate pepper seeds?
Pepper seedsGenerally, germination is best carried out 3-5 days before sowing, so it is important to pay attention to the timing of sowing. Usually when the temperature and bed temperature are high during spring and summer sowing, dry seeds can be sown directly without germination. However, sowing seeds in the cold season, such as planting peppers in greenhouses in winter, need to be soaked and germinated first to ensure the germination rate.
2. Germination method of pepper seeds
1. Ordinary germination method
After soaking the pepper seeds, wash them repeatedly with water to remove the spicy taste. Then wrap it in a cloth and put it in a basin, cover it with wet gauze, and control the temperature of 28-30 for germination. During the period, pay attention to wash twice a day with about 30 warm water, and it will take about 4-5 days to sprout.
2. Variable temperature germination method
Variable temperature germination is alternating germination at high and low temperatures. Wrap the soaked seeds in a damp cloth and place them in a warm place to germinate. Every day, the high temperature is controlled by 28-30 for 18 hours, and the low temperature is controlled at 16-20 for 6 hours. Regularly turn and scrub twice a day to make it evenly heated and wet, and the germination is strong and strong. Generally, after 4-7 days, when the germination reaches more than 80, it can be cooled to 10 for low-temperature refining for about 7 hours, which can be used for sowing.
3. Precautions for germination of pepper seeds
1. Drying and soaking seeds
Before germination, it is also important to dry and soak seeds. Drying seeds is to spread the pepper seeds in the sun for 2-3 hours; The soaking can generally be divided into two ways: warm soup soaking and bacterial liquid soaking.
2. Pay attention to ventilation
During the germination process, attention should be paid to adjusting the humidity for ventilation. Turn the seeds every 4-5 hours for ventilation and some water in time.
3. Ensure oxygen content
Pepper seed germination has very strict oxygen requirements, and the air permeability of gauze should be strengthened to ensure that the oxygen content is more than 10%.
4. Pay attention to preservation
If after successful germination, due to some influences (such as weather, etc.) can not be sown in time, the seeds should be stored in a humid environment of 5-10 years to be sown, otherwise the seeds are easy to spoil.
In general, there are many technical points that need to be mastered and paid attention to in the germination of pepper seeds, otherwise it is not conducive to improving the germination rate of seeds. In addition, when about 80% of the seeds have been exposed, it is necessary to stop germination and focus on the sowing process.
