The sweetness of the same variety of peach trees is different. What is the reason?

As we all know, there is a saying: "The orange in Huainan and the orange in Huaibei are oranges", which is very telling. In other words, all fruit trees have problems of suitable areas and unsuitable areas, and peaches planted in suitable areas are sweeter than those planted in unsuitable areas. Although the planting distance of peach trees is only tens of kilometers, the altitude is different and the temperature difference between day and night is different, so there is a question of suitability. Although it is the same peach tree variety, its sweetness will be different. Although peach trees are not too far apart, the soil quality will definitely be different. Generally speaking, there are more sandy soils in mountainous areas and more clay soils in lowlands. The sweetness of peaches varies with the soil quality. Generally speaking, peaches planted in sand or yellow soil are sweeter than peaches planted in clay.

Yellow mud, on the plot with poor soil permeability, bears peaches that are not sweet, and the hillside is sweeter than the plain, so it is not suitable for planting peach trees in the depression. Peach tree is a light-loving variety, so it is best to plant it in the north and south of the plot, with good light transmittance, high photosynthesis and high sugar accumulation.

To sum up, the sugar content of the same variety of peaches in different plots is obviously different.

Let's first understand the climate environment suitable for the growth of peaches. First, the climatic properties suitable for peach growth: most peaches like temperature and belong to fruit trees in warm areas; The optimum temperature for rooting and growth is about 65438 0 5℃ to 20℃. The basic temperature preference of branch growth is not lower than 65438 05℃ to 25℃; The temperature of fruit ripening is about 26 ~ 27℃. If the sun shines directly during the day, the maximum temperature is not higher than 35℃ and not lower than 20℃ at night.

The problem raised by the subject is not an individual phenomenon, but a universal phenomenon. The sugar content of the same variety planted in the same village may be different, not to mention dozens of kilometers apart. The soluble solid content mentioned by peach varieties is what we call sugar content. Simply put, the formation process of sugar is the process from quantitative change to qualitative change of macromolecular organic matter such as starch in fruits. In the process of transformation, the more favorable factors, the more favorable the accumulation of sugar and the sweeter the fruit. The sugar content mentioned in the new variety description is not a fixed value. The sugar content of new varieties measured in the research and development process is also affected by many factors. But in the final analysis, there are three reasons.
