When is the best time in kind of garlic?

Garlic, also known as Hu garlic, has good nutritional value and medical care value, and is also a good condiment. There is a saying in the northwest called? Eating meat instead of garlic will reduce nutrition by half? It also confirms the importance of garlic in people's daily diet. So when do you plant garlic? Next, talk about the cultivation season and sowing time of garlic.

First, the determination of garlic cultivation season

The cultivation of garlic depends not only on the local climate and environmental conditions, but also on the characteristics of varieties. In addition, different garlic needs different temperatures during its growing period. Therefore, the determination of cultivation season should be based on the requirements of different garlic varieties, the growth environment at different growth stages and the climatic conditions in various regions.

The planting season of garlic varies with the climate in different parts of China.

35 north latitude? Southern China: It is not too cold in winter, and garlic seedlings can safely overwinter in the open field, mainly sowing in autumn; 38 north latitude? Northern region: The temperature in winter is low and the climate changes greatly, so seedlings can't overwinter naturally in the open air, and autumn sowing is prone to freezing injury, so sowing in early spring is better; 35 north latitude? ~38? Inter-area: This area belongs to the transitional area, and it can be sown in spring and autumn. Autumn sowing is widely practiced in the Yangtze River basin. Because the growth period of autumn sowing is longer and the yield is obviously higher than that of spring sowing, it is best to carry out autumn sowing when the temperature environment is available. Second, the determination of sowing date of garlic in spring

The growth period of garlic seedlings sown in spring is obviously short, so it should be sown as early as possible in the suitable sowing period to prolong the growth period of garlic. Usually in the process of soil thawing? Japanese melting and liquid freezing? When you are ready, you can start sowing carefully.

The specific sowing date should be controlled at the local temperature of 3~6℃. Sowing in this temperature range can not only complete the process of low-temperature vernalization, but also ensure the germination of garlic, ensure the development of garlic root system during germination, promote the differentiation of flower buds and scale buds, and lay the foundation for the growth of garlic bolts and garlic heads.

If sowing is too late, the growth period of garlic will be greatly shortened, the growth temperature will be too high, and the growing point will not vernalize, which will easily form garlic bolts and reduce the yield. Of course, bulbous garlic also has a good market at present, so if bulbous garlic is planted, it can be used for planting. The farmer said? There won't be nine in kind of garlic, but there are only nine? It vividly illustrates the consequences of sowing garlic too late in spring.

Spring-sown garlic is mainly trafficked from other places because of its short growth period, poor flower bud differentiation, low bolting rate, poor bolting development and low yield. In fact, the division of garlic sown in autumn or spring is based on the climatic conditions in winter in the open field. Effective measures can be taken to change the overwintering conditions, and garlic leaves in spring sowing area can be sown in autumn, which can better take into account the production of garlic bolts and garlic heads.

Third, the determination of garlic sowing date in autumn

The sowing date of garlic in autumn sowing area mainly depends on the tolerance and dormancy characteristics of the outside world. Early sowing and late sowing have adverse effects on the normal development of garlic.

Premature sowing: sowing too early, garlic has not passed the dormancy period, and the high external temperature is not conducive to garlic emergence, and the seed petals will breathe and consume more nutrients in the soil. Even after the dormancy period of garlic, the seedlings sown too early grow too vigorously, consume nutrients before overwintering, and are vulnerable to freezing injury. It will reduce the overwintering ability of garlic, and it may spring again, causing secondary growth problems. In the second year, compound garlic will be formed, which will reduce the quality and commodity of garlic. Sowing too late: sowing too late, garlic seedlings are small, tender in tissue, weak in root system, with less accumulated nutrients and poor cold resistance, which can not guarantee strong seedlings to survive the winter. In winter, seedlings will die, which will affect the bolting and growth of garlic. Therefore, the sowing date of garlic must be strictly controlled to eliminate the unfavorable factors of garlic growth.

Judging from the climatic conditions, the suitable sowing date of garlic in autumn is generally when the daily average temperature is 20~22℃, and this period appears in the middle and late September in northern China; This period in the Yangtze River basin appeared from late September to mid-June. Considering the dormancy of garlic seeds, there is an effective growth period of 35~40 days before overwintering in the northern region, so that the seedlings will grow 4~5 leaves, because the plants have the strongest cold resistance at this time and can safely overwinter in the open field; There is a growing period of 60~75 days before winter in the Yangtze River basin, so it is appropriate to make seedlings grow 5~7 leaves.

Because garlic stops growing when the average daily temperature drops below 7℃, the sowing date can be calculated according to the local climate in each region. The suitable sowing date in the northern region is generally from September to the beginning of 10, as the agricultural proverb says? Mid-Autumn Festival is not at home, Dragon Boat Festival is not in the field? Xiao Jiu is not planted in seven big and eight miles, and there are no young garlic shoots in October? Lunar calendar. From the end of September to the beginning of 165438+ 10, the average yield of single garlic was reduced by 5.3g without delaying sowing for 7 days. During the period of11~ 65438+February, the rate of single garlic increased by 16% on average every 15 days thereafter.

Garlic planted with plastic film in autumn has strong growth potential, and can be sown after 5~ 10 days. If sowing is too early, it will lead to slow emergence and easy baking at too high a temperature.

It can be seen that the determination of garlic sowing date is closely related to local climatic conditions and varieties. Therefore, while determining the time required for a growth cycle of garlic planting, we should also master the local climate conditions and sow in time, so that the garlic planted can get a bumper harvest.
