Breeding methods and matters needing attention of basil

The small basil is an edible and medicinal plant. Family planting basil can not only be used as a green potted plant, but also can be picked and eaten when it is mature. The following will introduce the breeding methods and matters needing attention of basil.

1. Selection of basin soil

Basil is a deep-rooted plant, and its roots can be buried in 50cm to 100cm, so it is appropriate to choose well-drained, fertile and loose sandy loam and apply sufficient base fertilizer before planting. In family farming, the flowerpot is best chosen to be both deep and wide, so as to meet the deep root needs of basil.

Second, select seedlings to promote budding.

Because the frost-free period is short, it is necessary to raise seedlings in greenhouse or greenhouse in order to harvest seeds in open field. If you only eat tender stems and leaves, seedlings can also be direct seeded. The seedlings are usually sown in the middle and last ten days of April.

Put the seeds in a gauze bag, shake the water hard, cover it with a wet towel or gauze, keep warm and moisturized, 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 it once or twice a day to balance the temperature and sprout 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 sprouting, 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.

Third, planting time

From March to April in the south and from late April to May in the north, the sowing should be carried out on a sunny morning. The nutritive soil should be loaded into the sowing plate and watered thoroughly with hot water or warm water. After the water seeps, sprinkle a layer of medicinal soil, sow the sprouted seeds evenly on the plate, cover it with 1cm thick medicinal soil, cover with plastic film, keep warm and moisturizing. Water steadily after transplanting to ensure that the potted soil is moist.

IV. matters needing attention

Some flower friends balcony or flower bed is relatively large, will plant a lot of basil. At this time, we should pay attention to the maintenance and management of planting seedlings. Interseedling and seedling replenishment were carried out when the seedling height was 6cm to 10cm. Generally weeding twice, the first time in 10-20 days after emergence, shallow hoe topsoil. The second time is from early May to early June. When weeding, you can turn the soil by the way to keep the soil loose. If you are afraid of drought in the seedling stage, you should pay attention to timely watering. Flower friends raised in flower beds can properly apply some chicken manure water to maintain nutritional supply.

When breeding basil, we should choose sandy soil with good drainage and fertile looseness, accelerate germination before planting, sow seeds after the buds come out, and sow them at noon on a sunny day, sow them well and cover them with plastic film. In addition, pay attention to weeding twice in the seedling stage.
