How does basil grow?

1. Land selection and fertilization: basil is a deep-rooted plant, and its roots can be buried in 50-100 cm, so it is appropriate to choose sandy loam with good drainage and fertile looseness. Apply enough base fertilizer before planting, level off and rake fine, and make a flat or high bed of about 130 centimeters. In our country, because of the short frost-free period, we must raise seedlings in greenhouse or greenhouse in order to harvest seeds in open field. If you only eat tender stems and leaves, the seedlings can also be directly seeded, and the seedling period is generally sown in the middle and last ten days of April.

two。 Sow and raise seedlings: put basil seeds in a gauze bag, shake off the water vigorously, cover it with wet towels or gauze, keep warm and moisturizing, and germinate at a temperature of about 25 ℃. In the process of sprouting, rinse with clean water once a day, control clean, such as a large amount of seeds, turn 1-2 times a day, so that the temperature is balanced and budding neatly. The temperature in the early stage of budding can be slightly higher to promote budding. when the bud is about to come out (the seed will open its mouth), the temperature should be reduced by 3-5 ℃ to make the bud stout and neat. After budding, if you encounter special weather, you can move the buds to a place of 5-10 ℃ to control the growth of buds and wait for sowing.

3. Ploughing and topdressing: when basil seedlings are 6-10 cm high, interseedling and replenishment seedlings are carried out, 2-3 seedlings are left in each hole, and 1 plant is left in strip sowing according to 10 cm. Generally ploughing and weeding twice, the first time in 10-20 days after emergence, shallow hoe topsoil. The second time is from early May to early June, before the seedlings are closed, and after each intertillage, human and animal dung water should be applied. If you are afraid of drought in the seedling stage, you should pay attention to timely watering.

4. Harvest time: basil stems and leaves are harvested from July to August, cut the whole grass, remove fine roots and impurities, and dry. When the plant is 20 cm high and the ridge is closed, the unbolted young twigs are harvested at the front end, with a length of 5-10 cm, once every 7-15 days. The essential oil is extracted when the inflorescence is ready.

5. Harvest and processing: when harvesting basil, cut the plant 20-25 cm above the ground with a sickle to avoid shaking the root system so as not to affect the ability of regeneration, and then strengthen fertilizer and water management to promote its re-germination of new stems and leaves. Processing should be carried out as soon as possible after harvest to prevent the wound and leaves from turning brown and yellowing, affecting the quality of essential oil.
