Garlic is an essential condiment in the kitchen, and it has high medicinal value, so it is in great demand in the market.

Because of this, the planting area of garlic in China is also very extensive, and the producing areas include Shandong, Jiangsu, Guangxi, Sichuan, Anhui and other provinces and cities, and there are not a few high-quality garlic produced, which also benefits from scientific seed selection technology.

Good varieties can have better growth characteristics, which is also very helpful to improve the yield.

garlic seed selection technology

When selecting garlic seeds, we should try our best to choose garlic seeds with few garlic petals, big garlic heads, no diseases and large terminal buds, and pay attention to eliminating moth-eaten, rotting and rotting garlic seeds during seed selection.

In addition, the varieties suitable for cultivation should be selected according to the regional environment. For example, early-maturing purple garlic should be selected in southern China, and medium-sized garlic balls should be used as seeds.

In addition to seed selection, extra attention should be paid to the physiological dormancy period of garlic seeds.

When preparing garlic seeds, you should choose garlic seeds that have finished dormancy, because this can make them emerge early.

However, after selecting garlic seeds, it is necessary to break the petals to remove the dried stems and remove the damaged garlic petals.

at the same time, in order to prevent the damage of alkali returning to garlic seeds, try not to peel them.

And after seed selection, some treatment methods should be adopted:

1. Sun-drying: Before sowing, spread the garlic seeds in the sun for 2-3 days, and be careful not to spread them on the cement floor or on the equipment that is easy to heat up after being irradiated by the sun.

By airing, garlic cloves can be loosened, and the cloves are easy to break off, and garlic cloves will not be damaged at the same time.

Garlic seeds germinate quickly and emerge uniformly after air drying.

2. soaking: soak the dried garlic seeds in clear water for 12 hours, then take them out, and air them in the sun for 1 day again, and then sow.

3. Cold storage: Cold storage is a common treatment method used by growers in recent years to break the dormancy period of garlic seeds.

the dormancy period of garlic seeds can be broken by peeling garlic into garlic cloves, putting them in a constant temperature fresh-keeping warehouse about 1 days before sowing and storing them at a temperature of about degrees for about 1 days.

4. Pesticide: Through pesticide treatment, the dormancy period of garlic seeds is broken, so that they germinate in time.

This method can not only improve the emergence rate, but also increase the yield and income.

sow garlic after seed selection

1. Sowing time

Generally speaking, the growth period of garlic is different due to different cultivation seasons, and the whole growth period of spring sowing garlic takes 9-1 days.

Shandong is generally suitable for sowing in mid-February and harvesting in early June; Beijing, Tianjin, Ningxia, Gansu, Shaanxi and other regions are suitable for sowing in early March and harvesting garlic heads in late June; Xinjiang, Qinghai, Heilongjiang, Liaoning, Jilin, Inner Mongolia and other regions are suitable for sowing in early and middle April, and harvesting garlic heads in middle and late July.

autumn sowing garlic, Yunnan, Guizhou, Sichuan, Chongqing, Hubei and other places, is suitable for sowing from late August to early September, and harvesting garlic heads from May to middle and late June of the following year.

Hunan, Zhejiang, Jiangxi, Fujian, Jiangsu, Anhui, Shanghai, Henan and other regions can sow in late September to early October.

2. Sowing method

When garlic is sowed in spring, it takes about 15 days to sprout and come out because of the low ground temperature.

It is best not to water before emergence. If soil drought affects emergence, you can water it with a little water as appropriate, and then hoe it to facilitate rooting and emergence.

sow garlic in spring as soon as possible after soil thawing, and adopt high ridge cultivation, so that the ground temperature is high, the seedlings emerge quickly, and the bulb expansion is less affected by soil resistance.

the suitable depth of ridge cultivation is 3-4cm, and the border cultivation is 2-3cm.

To sow garlic in autumn, garlic seed petals can be soaked, which can not only promote simultaneous germination and early germination, but also sterilize and reduce diseases. For example, after soaking for 12 hours with carbendazim and lime water, rinse with clear water before sowing.

before planting, deep ploughing and soil preparation should be carried out, with fully decomposed organic fertilizer as the main method and sole fertilizer applied.

The above is an introduction to the scientific seed selection technology of garlic and the sowing matters after seed selection. I hope it will be helpful to everyone.
