Why do plants germinate in spring?

Spring has come, and the sunshine time has become longer. The leaf primordium in dormant buds is stimulated, which reduces the concentration of abscisic acid in plants, increases the content of growth regulators, and some enzymes necessary to break dormancy and germination begin to synthesize, thus promoting the synthesis of protein.

Another factor is that low temperature in spring will increase the hydration degree of dormant buds of plants, and hydrolase and oxidoreductase will become active, which will promote the transformation and respiration of organic matter and make animals start to sprout and grow. The conditions needed for plants to break the dormancy state are the same as the natural conditions in spring, which is an adaptability formed in the long-term evolution of plants.

Spring, also known as spring, is the first of the four seasons, which refers to the period from beginning of spring to long summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain. This is the season when everything comes back to life. The Gregorian calendar in the northern hemisphere is March-May, and in the southern hemisphere (such as Australia) it is September-165438+ 10. In meteorology, the beginning of spring is that the average temperature is above 10℃ for five consecutive days. In spring, the climate is warm and mild, and there is rain in most inland areas of China, where everything germinates and the climate is changeable.

It gets warmer and warmer in spring. At this time, Yang is rising. The diet should be light, peaceful, nutritious and balanced. Protein, carbohydrate, fat, vitamins and minerals in food should be kept in corresponding proportions. Avoid eating greasy, spicy and fried foods, which are difficult to digest and will increase the burden on the stomach and liver. In addition, eat more fresh seasonal fruits.

Liver function is vigorous in spring, and sour food makes liver qi more vigorous, which leads to the decline of digestion and absorption function of spleen and stomach, while sweet food can enhance the qi of spleen and stomach and is beneficial to health. Therefore, the spring diet should be more sweet and less sour, and jujube is a good choice among sweet foods.
