Choose a place
Basil is a deep-rooted plant, and its roots can penetrate 50-100 cm into the soil. Therefore, it is advisable to choose a sandy loam with good drainage and fertile loose soil. Before planting, apply foot base fertilizer, level, and rake, and make a flat or high border of about 130 cm.
Since the frost-free period is short, it is necessary to harvest seeds for open field cultivation and production. The seedlings must be raised in the greenhouse or greenhouse. Seedlings are usually planted in mid-to-late April. Put the seeds in a gauze bag, shake off the water vigorously, cover it with a wet towel or gauze, keep it warm and moisturize it, and place it at a temperature of about 25°C for sprouting.
In the process of accelerating germination, rinse with clean water once a day to control the cleansing. If the amount of seeds is large, turn 1 or 2 times a day to balance the temperature and make the germination neat. The temperature in the early stage of germination can be slightly higher to promote germination. When the buds are about to emerge (the seeds will open their mouths), the temperature should drop by 3 to 5°C to make the buds thick and tidy. After the buds have emerged, if you encounter special weather, you can move the buds to a place at 5-10°C to control the growth of the buds and wait for sowing.
