Garlic is the most common spicy seasoning, with large planting area, high yield and remarkable economic benefits, which has become the leading industry in many places. Moreover, the proper sowing time is also very important, which has certain influence on the overwintering growth of seedlings.
garlic planting time
garlic is usually planted in spring and autumn, with a long planting time in autumn and a relatively high yield, while the climate in the south is humid. In order to ensure that garlic can be planted safely in winter, it is generally chosen to plant garlic in autumn, while it is generally chosen to plant garlic in spring in the north and spring in the north.
1. Planting in autumn
The temperature in autumn planting is generally around 22℃, so it is necessary to reserve a month's growth time before winter, so as to effectively avoid garlic from being affected by low temperature in winter.
If garlic seedlings grow for one month, their cold resistance is also strong. When the average ground temperature is lower than 7 degrees, garlic will stop developing. Therefore, the temperature change is the key period of garlic planting, usually planting around autumn is around October, and using plastic film to cultivate garlic can be delayed by one week.
2. Planting in spring
The growth period of garlic planted in spring is shortened, so early sowing can prolong the growth period in a proper planting period, and the temperature is usually around 12 degrees. Generally speaking, when the temperature exceeds 1 degrees, garlic can germinate, and with the temperature rising, the growth rate of garlic will also accelerate.
How to plant garlic
1. Choose garlic varieties
Among them, purple garlic with large garlic petals and early maturity is the best. Stress resistance and disease resistance should be paid attention to, and the yield of garlic bolting should be highlighted.
2. Choose garlic as seed.
Garlic trays and stems can prevent absorption and must be removed. Classify garlic cloves, and select full garlic cloves without diseases and insect pests and damage as seeds.
3. airing seeds+soaking seeds to accelerate germination
airing for 1-2 days can make garlic seeds germinate, but avoid high temperature exposure. Then soak the seeds in clear water for 1-12 hours, then put the seeds in wet sand to accelerate germination, and sow them immediately after germination.
When garlic is sown in high temperature season, the dormancy period should be broken and the garlic seedlings should be broken. The ambient temperature should not exceed 3℃. Germination is usually accelerated at 15-2℃.
it can be placed above the water surface of deep wells, in kilns, cellars, basements and other cold places. Low temperature can be placed indoors with heaters, on electric blankets or in greenhouses for heating treatment to speed up the germination process.
4. It is necessary to cool down after sowing in high temperature season.
After accelerating germination, the seeds should keep high soil moisture to avoid burning seedlings at high temperature. Timely grass curtain or double-layer sunshade net.
5. Applying sole fertilizer
Garlic seedlings have higher nutritional requirements. When preparing soil, 3 kg of decomposed farm manure and 3 kg of ternary compound fertilizer can be applied per mu, and diluted decomposed human excrement and urine can be applied in the sowing line.
