What is the frost free period ? Please explain in layman s terms. Thank you

The frost-free period refers to:The frost-free period is the entire period of the year after the final frost and before the first frost. During this period, no frost appeared.

The growing period of crops is closely related to the frost-free period. The longer the frost-free period, the longer the growth period. The length of the frost-free period varies from place to place, and generally the lower the latitude and altitude, the longer the frost-free period.

Nature:

The length of the "frost-free period" in a region is mainly related to the length of the cold season in that area. That is to say, in the cold season, the end time of the "final frost" is late, the "first frost" starts early, and the "frost-free period" is shorter.

In contrast, in areas with a short cold season, the end of the "final frost" is early, the "first frost" starts late, and the "frost-free" period is longer. This is because frost occurs when the weather is relatively cold, and when the temperature near the ground and the surface of crops drops to zero degrees Celsius or below, the water vapor attached to the surface of the object can condense into white frost.

The frost-free period refers to the number of days between the last frost in spring and the earliest frost in autumn. In actual production, it is the frost that is really harmful, so it should be called the frost-free period, that is, the number of days between the last frost in spring and the first frost in autumn. The temperature indicator of frost is generally considered to be when the air temperature is 1 degree Celsius or the ground temperature is below 0 degrees Celsius.

The final frost before May only has an impact on the crops transplanted by seedlings, and the final frost appears in June, which has a greater impact on most of the crops that emerge, and the same early frost in autumn has little impact on most crops if it appears in late September, and if the first frost appears in mid-September, it will affect the safe maturity of most crops, resulting in reduced yield and excessive moisture.

The frost-free period is the entire period of the year after the final frost and before the first frost. During this period, no frost appeared. The growing period of crops is closely related to the frost-free period.

The longer the frost-free period, the longer the growth period. The length of the frost-free period varies from place to place, generally latitude and altitude.

The frost-free period is more than 300 days, in the middle and lower reaches of the Yangtze River.

250-275 days, North China.

It is 175-225 days, and about 100-150 days in the northern part of Northeast China, Inner Mongolia and northern Xinjiang. The general distribution is characterized by a long frost-free period in the south and a short frost-free period in the north (Qinghai-Tibet Plateau).
