Selection and sowing of garlic

1. Selection of species

Garlic is propagated with garlic cloves. Early-maturing purple garlic is suitable for cultivation of garlic seedlings in Changsha area, and medium-sized garlic balls are suitable for planting. When planting garlic cloves, you have to go through strict "two choices and one point", that is, when buying garlic balls, you should choose garlic with the morphological characteristics of this variety, that is, the garlic has the same size and color, the appearance is fat and full, and it is relatively dry, and there is no "sprout garlic" on the garlic. Before sowing, the petals should be selected, the garlic heads should be broken, the damaged bud tips or rotten, yellow and naked petals should be removed, and the complete, medium-sized and flat garlic cloves should be selected for garlic seedling cultivation.

two。 Sowing date and sowing method

The sowing date of garlic seedlings on the market in Changsha area can be sown in batches from late July to October. Early sowing garlic is in hot and hot weather, it is not easy to sprout, because high-temperature scalding is easy to "oil", but not sprouting, it is necessary to carry out low-temperature treatment. Garlic cloves can be hoisted with gauze in a deep well for one day and night, or washed in cold water and placed in a cold hole in the ground. Two weeks later, when it is found that the garlic cloves have taken root, they should be sowed immediately. In the rest of the time, sowing wet seeds also emerged earlier and evenly than dry seeds.

3. Sowing density

Garlic seedling cultivation and sowing is relatively dense, on both sides of the open planting ditch, respectively, according to the plant distance of 3 cm to insert a garlic clove, the seed tip is up, insert steadily, every 666.7 square meters with 300kg. After garlic insertion, dripping with prepared mature human and animal dung in the planting ditch, covering with thin soil, and then covered with rice straw or wheat straw, or covered with a small arch shed to cover the sunshade net, some interplanting hot cabbage between ditch rows, which is not only conducive to garlic soil moisturizing and early emergence, but also to promote the growth of garlic shade and cooling. When the garlic seedling is 20-25 cm high, pull out the cabbage.
