Is there a saying that autumn fertilizer is golden winter fertilizer and copper spring fertilizer is broken copper and iron? Why?

Autumn fertilizer is gold, winter fertilizer is copper, and spring fertilizer is scrap iron? This sentence is said by fruit farmers in many areas, and in some places? September is gold, 10 is silver, and the twelfth lunar month is quite broken. . Either way, it means the importance of early application of autumn fertilizer. It is mainly used for harvesting fruit trees, especially apple trees and peach trees in autumn. And this sentence also has scientific truth in it. Today we will talk about the importance of applying base fertilizer to fruit trees in autumn.

Why is it better to apply base fertilizer to fruit trees as early as possible in autumn?

1. At this time, the fruit trees are the weakest and need nutrient supplement urgently: from the end of September to the middle of 10, most fruit areas have been picked, and at this time, the fruit trees are the weakest in a year and need a lot of nutrients urgently, which is why it is called autumn fertilization. Moon fat? Because.

2. Conducive to nutrient storage: Although harvesting is completed in autumn, the leaves of the trees have not fallen, so the photosynthesis of fruit trees is still going on. The application of base fertilizer is beneficial for fruit trees to store nutrients and provide adequate nutrient supply for the coming year. If you wait until the cold winter to apply base fertilizer, it will be useless, just move the fertilizer to a new place.

3. Conducive to root growth: Autumn is the second peak season for root growth of fruit trees. After the fruit is picked, the trees basically don't need too much nutrients. At this time, when the base fertilizer is applied, the nutrients will go down and promote the root system to take root deeply. As we all know, roots are the key to the good growth of any plant. Only when the roots grow strong can we ensure an adequate supply of nutrients next year.

4. Conducive to flower bud differentiation and strong autumn shoots: autumn is also an important period for flower bud differentiation of fruit trees. With sufficient nutrition supply, flower buds will definitely differentiate better. In addition, the autumn shoots will grow stronger, and there is another advantage that the base fertilizer in autumn is mainly organic fertilizer, which improves the overwintering and drought resistance of fruit trees. The quality of flower bud differentiation directly affects the flowering and fruit setting in the next year.

5. Conducive to the improvement of orchard soil: Organic fertilizer is the main base fertilizer, which not only provides comprehensive nutrients, but also plays an important role in soil improvement. When the soil conditions are good and the roots breathe smoothly, the growth of trees will naturally flourish, and organic fertilizer also has the ability to adjust the ground temperature and maintain water and fertilizer.

In short, based on the above points, we all suggest that the earlier fruit farmers apply base fertilizer, the better. Early-maturing apples have plenty of time to fertilize in autumn. Apply base fertilizer to mid-late ripening apples before or immediately after picking. Because this directly affects the yield and quality of fruit trees in the second year. Don't let the base fertilizer really become? Scrap copper and iron? .
