How long is a growing season and how many days are in a season

A growing season refers to the period from spring to autumn, usually 3 months to 6 months. In temperate regions, this time period is usually from March to November each year, but the exact time varies from region to region and year to year. In the tropics, the growing season can last all year due to warmer climates.

During the growing season, plants go through a series of growth stages, including budding, budding, flowering, fruiting, etc. During this time period, plants need to absorb sufficient nutrients and water for photosynthesis and material accumulation, which promotes their growth and reproduction.

It is important to note that the timing and length of the growing season may vary due to meteorological factors and geographical location. For example, in cold regions, the growing season may be shorter, while in areas with mild climates, the growing season may be longer. In addition, different plant species also have different growth rhythms and ability to adapt to the environment, so the specific time of the growing season needs to be judged on a case-by-case basis.

The average is about 5 months. The growing season is the period of the year when plants grow significantly, also known as the growing season. The length of the growing season is closely related to the temperature conditions, if the average growth cycle in all regions of the country is about 5 months, because the growth cycle is longer in the north and shorter in the south.

A season is about 90 days, and there are four seasons in a year: spring, summer, autumn, and winter, a season has three months, and a month has 28 days, 30 days, and 31 days according to the size of the month. Thus 90 days in the spring months, 91 days in the summer months, 92 days in the autumn months, and 92 days in the winter months.

The seasons are several time periods that occur in circulation every year. Different regions have different divisions of seasons. In terms of temperate zones, especially in China's climate, the year is divided into four seasons, namely spring, summer, autumn and winter; And for savannahs there is only a dry season and a rainy season.

In the cold zone, it is not only winter that allows the envy to be envied, but also the four seasons can be separated at the north and south poles.

A season is about 90 days, a year has spring, summer, autumn and winter four seasons, a season has three months, a month according to the size of the month has 28 days, 30 days of smiles, 31 days of stupid fiber. Thus 90 days in the spring months, 91 days in the summer months, 92 days in the autumn months, and 92 days in the winter months.

The seasons are the periods of time when the geographical landscape varies greatly from year to year. Different regions have different divisions of seasons. In terms of temperate zones, especially in China's climate, the year is divided into four seasons, namely spring, summer, autumn and winter; Whereas the belt imitation for the savannah only has a dry season and a rainy season.

In the cold zone, the four seasons are not only in winter, but also in the north and south poles.

A season is about 90 days, a year has spring, summer, autumn, winter four seasons, a season has three months, a month by month so that the size of the envy limbs are divided into 28 days, 30 days, 31 days. Thus 90 days in the spring months, 91 days in the summer months, 92 days in the autumn months, and 92 days in the winter months.

The seasons are the periods of time when the geographical landscape is relatively different from each other that occurs in a cycle every year. Different regions have different divisions of seasons. In terms of temperate zones, especially in China, the year is divided into four seasons, namely spring, summer, autumn and winter. And for savannahs there is only a dry season and a rainy season.

In the cold zone, the four seasons are not only in winter, but also in the north and south poles.

There are about 90 days in a season, but there are many astronomical seasons, climatic seasons, phenological seasons, etc., and the specific number of days in different divisions is also different, such as the astronomical season spring, summer, autumn and winter are 91 days, 94 days, 92 days, and 88 days respectively.

The phenological season is based on the four of the 24 solar terms (the beginning of spring, the beginning of summer, the beginning of autumn, and the beginning of winter) as the starting point of the four seasons, and the two equinoxes and solstices as the midpoints. For example, the beginning of spring is the starting point, the ecliptic longitude of the sun is 315°, the spring equinox is the midpoint, the beginning of summer is the end point, the ecliptic longitude of the sun becomes 45°, and the sun runs 90° on the ecliptic.

This is a traditional, common method.

The astronomical season is determined by the position of the Earth on the ecliptic. That is, from the beginning of spring to the beginning of summer for spring, from the beginning of summer to the beginning of autumn for summer, from the beginning of autumn to the beginning of winter for autumn, and from the beginning of winter to the beginning of spring for winter.

Spring, summer, autumn and winter are 91 days, 94 days, 92 days, and 88 days respectively. Chinese folk are accustomed to using a lunar calendar, with the month as spring, the month as summer, the month as autumn, and the month as winter. The exception is the year of the leap month, which is basically similar to the former.

The astronomical seasons reflect the seasonal variation in the height of the sun in a year. Because the solar radiation reaching the ground is affected by the ground and the sea and land, and its thermal effect is about a month behind the solar radiation effect, so the solar month is often regarded as the spring month, the summer month as the autumn month, and the autumn month as the winter.

Reasons for the change of seasons.

The change of seasons is caused by the rotation of the earth, and the orbital plane where the earth's revolution and rotation are located has an angle, so the earth rotates obliquely when it rotates, so there will be a phenomenon of the change of seasons, and the difference in the speed of revolution also leads to the unequal length of the four seasons on the earth.

In different parts of the earth, rotated to different positions, the solar radiation and heat are different, so there will be a climate without sails, which is often called spring, summer, autumn and winter.
