Why does the growing season of crops become longer when the temperature rises, but it is said that t

The period of growth during the year when the plant is visibly visible is called the growing phase. The growing season is closely related to the temperature conditions, and the growing period is called when the growth can continue at a certain temperature. Usually, the average daily temperature5 serves as the boundary.

Therefore, the higher the temperature, the longer the growing period of the crop. That's the right science.

As for "but the crop will ripen early", the factors involved include the differences in the characteristics of different crops, as well as the factor of temperature (the difference between day and night temperature in different regions). As a result, only one crop of rice and wheat can be produced in the north, but two crops in the south.

The growth period here is the time suitable for the growth of crops, the temperature in the south is high and suitable for the growth of rice for a long time, that is, the growth period is long, and the temperature in the north is lower than that in the north in the same period, which is not conducive to the growth of rice, and the life period is short. The so-called early maturity is due to the fact that the temperature required for each growth period of rice is different, and when it reaches this temperature, it grows well, and the time when that temperature reaches is different every year. If the time comes early, it is called precocious.

The temperature must be suitable for the growth temperature of this type of plant.

The growing period here has two meanings, one refers to the time when the crop can grow; The greater the accumulated temperature, the longer the crop growth period.

Rather, it refers to the time that the crop experiences from sowing to harvesting, that is, the higher the temperature, the shorter the crop growth period.

So it depends on the specific information given to answer the question.

The larger the accumulated temperature, the longer the crop growth period, which means that the crop can grow for a long time in a year, such as the annual growth period, the 9-month growth period, etc. What you're talking about is that the higher the accumulated temperature, the shorter the growing period of crops in a given season, and the more crops are harvested in a year.

The accumulated temperature value of the Northeast Plain of China is low, the crops are ripe once a year, and the rice of this season grows for a long time in the ground, and the rice is delicious. The southern plain of our country is the growing period all year round, and rice can be harvested three times a year, and the rice in each season grows in the ground for a short time.

The crop growth period here refers to the time suitable for the growth of crops, not the growth cycle of a crop as you understand it.

Not necessarily. What you say is incomplete.

1. The growth cycle is long, and the crop quality is high, which is basically correct. It takes a long time to accumulate more nutrients.

2. The temperature is low, this statement is not comprehensive. The requirement is that there is enough sunlight and high temperature during the day and low temperature at night. in order to ensure nutrient accumulation. This will be of high quality.

During the day, there is enough light and the temperature is high, which is conducive to photosynthesis and produces a lot of nutrients. The temperature is low at night, which reduces the effect of respiration and reduces nutrient loss.
