A little trick to sprout balsam pear

First, prepare about 55 ℃ of warm water and put it in a boiled water bottle or other container that can keep warm; put the balsam pear seeds in a gauze bag, wash them with clean water, and gently wipe the seeds to remove the impermeable substances on their surface. Soak the washed seeds in warm water, keep for 10 minutes, stir constantly, then add cold water to lower the water temperature to 25 ℃-30 ℃, soak for more than 12 hours, remove the seeds, wrap them in a wet cloth, put them in a box, cover them with a wet cloth, and place them in a place that can maintain a temperature of about 30 ℃ and have enough humidity to accelerate germination. In the process of accelerating germination, it should be checked twice a day, not only to prevent water loss, but also to prevent excessive moisture and rotten seeds. After 2-3 days, the seeds can be sown when the radicle is about 3 mm. Second, soak the seeds in about 55 ℃ of warm water, naturally cool and continue to soak the seeds for more than 12 hours, rinse the seeds in clean water, break the navel of balsam pear seeds slightly with teeth or sharp-nosed pliers, and then place them in a place that can maintain a temperature of about 30 ℃ and sufficient humidity to accelerate germination, and then sow seeds when the seeds are exposed to about 3mm.
