Sowing time
The lotus seed of bowl lotus has no dormancy period. As long as the water temperature can be kept above 16 ℃, it can be sown in four seasons. Under suitable temperature and light, it takes 50-60 days from sowing to flowering in spring and 60-80 days in autumn.
Seed treatment
The shell of the lotus seed is hard and dense, and it must be artificially broken before soaking the seed. There is a small protruding tip on one end of the lotus seed and a small concave spot on the other. Wear out the small concave end and wear out a layer of skin on the rough cement floor, be careful not to hurt the kernel inside, and don't shell it. The purpose of skin grinding is to let water seep in through this gap, so that the seed absorbs water and expands.
Soaking seeds to accelerate germination
Soak the seeds with broken shells in warm water of about 20-40 degrees. When the water temperature is lower than 20 degrees, the seed germination and growth is too slow, and when the family soaks a small amount of seeds, it can be put into a thermos to keep warm. The speed of germination is also related to the temperature. under the condition of 30 degrees, generally soaking seeds to accelerate germination for 3-5 days, the germ protrudes from the breach. During this period, change the water every 1-2 days. In general, as long as the seed coat can absorb water and expand, it can sprout.
