Garlic is inextricably linked to everyone's life, both as a spice and as a health dish. It is important to have good garlic because of the large number of food items made of garlic, which some people cannot leave. So, in the period between july and august and january/february of the following year, there is a garlic crop, and at what point does it produce more than garlic? How do you determine the duration? Let's talk about this。
I. Level-specific strategy, autumn
The north and south of the country are far more diverse, and the planting period for garlic can be divided into autumn and spring broadcasts due to regional differences in the variety of uses. Geographically: 35° n, 38° n is the line between spring and autumn garlic. Winters south of 35 degrees north are not cold. Garlic seedlings can naturally reach winters and are found in the autumn area, where the sowing temperatures range from 20 to 22 degrees daily. In the cold winters north of 38° n, the seedlings are not safe enough to survive the winters, and should be sowed in the early spring as a spring area at temperatures ranging from 3 to 6 degrees daily. The area between 35° n and 38° n is a mixed area of spring and autumn. Although the specific planting dates vary widely, the harvest period is similar, ranging from 15 to 20 degrees in temperature to 13 hours in sunlight to garlic。
According to the broad zoning, the latitude at which you are placed determines whether you need to plant garlic in the spring or in the autumn, so as to be able to count, for example, in the area of the xinbei region, which is about 32 to 34 degrees north and is the area of the autumn。
Ii. The agricultural proverb determines the broadcasting period
The proverb concerning the planting of garlic is “85 (charlie) is not at home, mid-may is not at noon”, that is to say that garlic must be planted on the ground until august 15th of the mid-autumn week, when it is planted, and when it returns home at the end of the year. There is also the saying “white onions, greasy garlic”, which means that it's the best time to grow onions when it's white, and when it's cold, that's around the beginning of october, it's the best place to grow garlic, it's colder, it's cooler, it's colder, it's just the right temperature to sow in the cold, it's good for garlic to grow and it's better to grow. Taken together, on august 15, the agricultural calendar largely coincides with the period set by the two proverbs in the run-up to the late september or early october festival of the sun。
Specific planting dates based on the temperature required for growth
These two pretenses determine only the approximate extent of seeding at the appropriate time, starting from the date of planting and depending on temperature changes。
In autumn, the most suitable temperature for the seeding of garlic is 16-20°c, which stops growing when the average temperature of the day is reduced to 7°c and below. According to this characteristic, the most appropriate planting period for the planting of garlic in the autumn is when the average daily temperature is 20-22°c, which ensures that garlic can grow about five leaves, 20 centimetres high and below, before winter, at a time when garlic seedlings are the most resistant to cold, ensuring that garlic can get across the winter. Therefore, observing changes in temperature before the expected sowing period is approaching is the starting date for seeding when the average temperature dropped to 22 degrees in five consecutive days. Care must be taken that the temperature is steadily reduced to the required temperature, and that it is not possible to sow at 22 degrees in one or two days. Failure to pay attention to this may result in early transmission。
In recent years, the climate has warmed and the temperature has remained high, as in the case of the winter season, in which case planting is done in a timely manner, without waiting for cooling. Because the heat is only temporary, the drop is likely to be low in two or three days, and the temperature may not be higher in the future. This is called hot end cold seeding, which does not affect garlic growth because of the high temperatures。
