How to keep the garlic seed? What skills do you have?

Because garlic is asexual reproduction, garlic cloves are abnormal lateral buds and are part of the parent body of garlic, long-term asexual reproduction will inevitably lead to the accumulation of viruses in the body and the accumulation of other bad characters, resulting in the degradation of garlic breedings. so how can garlic keep seeds to overcome this problem? What skills do you have?

First, how to keep the garlic seed? What skills do you have?

1. Set up garlic planting fields in different places.

The establishment of garlic farming with certain regional differences and cultivation differences can avoid the degradation of garlic, improve the species character of garlic, and have a certain advantage of off-site growth. Such as mountain and plain exchange, arid and rice area exchange, vegetable garden and grain area exchange, remote exchange in different directions within a certain range, such as south and north, east and west, all these can increase garlic and seed yield to varying degrees.

2. Choose the disease-free and insect-free garlic with the characteristics of this variety as garlic seed.

The selection standard is the plant with the morphological characteristics of the variety, the leaves are free of disease spots, the garlic head is hypertrophic, the color is the same, the number of cloves is moderate, there is no insect source, and the seed garlic is disease-free and virus-free. After being selected, the garlic should be collected in small bundles, and the garlic should be dried and stored under cool and ventilated conditions. high temperature and humidity will reduce the vitality of garlic scale buds and even cause rotten seeds.

3. Use aerial bulb as seed

In order to improve the species character and vigor of garlic, the aerial bulb of garlic can be used for propagation. The method is that after bolting in the later stage of garlic growth, the garlic bolts are not harvested, and the harvest time of garlic is delayed for 15-20 days. When the garlic bolts turn yellow and the aerial bulbs develop and mature, the garlic bolts with diameter larger than 0.4cm are screened for summer storage. In the first and middle of September, the number of seedlings per 667m2 was 12 ~ 150000, then covered with soil 2cm or so, and watered after suppression.

In the future, the management is the same as that of garlic sown with cloves. When the aerial bulb is sown, it is common to grow single-headed garlic in the first year. If the single-headed garlic is well collected, it can grow into normal garlic in autumn, and the garlic will obviously increase with good quality and strong growth potential. Using this method to propagate garlic seed is the main method to improve the seed quality of garlic and prevent the degradation of garlic. This method is not suitable for some varieties, such as garlic without bolting or thin bolting and bulbous garlic can not be propagated by this method.

4. select and breed non-toxic seedlings and introduce virus-free garlic seeds.

In recent years, scientific research departments have adopted garlic detoxification measures to keep seeds, and the detoxified garlic seeds can obviously increase production. However, it must be an original or improved variety, and the yield-increasing effect is not obvious if it is more than 3 generations, and the virus-free garlic should not be harvested too late, otherwise it is easy to cause loose cloves and affect the commercial value of garlic.

5. Garlic that has experienced secondary growth can not leave seed.

Due to cultivation, climate and other conditions, the field of secondary growth of garlic, that is, "horsetail garlic", can not be selected. The secondary growth of garlic itself is a kind of degradation, which affects the yield and quality of garlic.

Second, how to sow garlic?

1. Land preparation

Ploughing depth is generally about 20cm, to fine ploughing, raking flat, raking solid, no obvious bumpy, to achieve "neat, loose, broken, clean." According to the water source, the length of the border can be 80-100m long and 4.2-4.4m wide, and that of 40m-50m long and 4.2-4.4m wide.

2. Seed selection

Peel and break the peel manually, remove the tray and stem plate of garlic, classify them according to large, medium, small and garlic heart, and treat the small garlic cloves according to the specific conditions. Seed selection requirements are pure white without red tendons, no scars, no saccharification, no light skin. The principle requires that each grain weighs about 5g. Seed size is the key to high yield.

3. Sowing seeds at the right time

Garlic should be sown at the right time. The planting time is at the end of Bailu and the beginning of the Autumn Equinox (late September and early October), and the temperature is about 17 ℃. The garlic cloves should be dried for 1 or 2 days before sowing.

4. Reasonable close planting

General row spacing 20cm, plant spacing 16~17cm, about 20 000 plants per 667m2. Deep 5cm or so, cover the garlic with soil 1cm after planting.
