Text/Native Life Gardening
The life of the fruit tree is constantly going through the process of growth, fruit, renewal and aging, and they are carried out in an orderly manner. The interaction of various organs in this series of processes also shows rhythmicity.
The growth law of fruit tree organs is mainly determined by heredity, and at the same time it will be affected by environmental factors. Fruit trees are seed plants, consisting of roots, stems, leaves, flowers, fruits, and seeds. These constituent organs can be divided into vegetative organs and reproductive organs, the main functions of roots, stems and leaves are absorption, synthesis, transfusion, they are generally regarded as vegetative organs; and flowers, fruits and seeds, play an important role in the reproduction of offspring, generally regarded as reproductive organs. The vegetative growth and reproductive growth of fruit trees will be carried out in an orderly manner every year, not only before and after, but also the phenomenon of overlapping occurrence and mutual influence. As growers, we understand these laws of fruit trees, which helps to understand the process of fruit yield and quality formation, so that we can scientifically formulate management technical measures. So, today we will understand the relationship between the vegetative growth and reproductive growth of fruit trees.
The vegetative growth of most fruit trees is carried out in the early stages, and the reproductive growth is carried out in the later stages, which is very orderly. Vegetative growth is the basis of growth and development, and reproductive growth promotes the development of reproductive organs and affects vegetative growth. As the number of fruit trees increases, the total weight of the fruit per plant has little effect, but the dry matter accumulation of stems and leaves is greater. The clear point is that although the amount of fruit is large, the yield and quality are not necessarily high, but have a greater impact on the vegetative organs of the tree; then there may be premature aging of fruit trees and shortening of tree age.
The relationship, influence, dependence, etc. between vegetative growth and reproductive growth are mainly manifested in the distribution of nutrients, of which the reproductive organs affect the distribution of nutrients the most significantly, and different fruit trees will have different nutritional needs. For example, the nutrients required by the axillary buds of the apple tree mainly come from the leaves of this node, and occur later and of poor quality; the nutrients of the top buds on the short branches come from the large leaves on the lotus branches. At the beginning of fruit development, the ability to transport nutrients is large, and the ability to transfer nutrients in the middle and late stages is small, at this time, if the new shoots are strong, it can lead to the backflow of fruit nutrients and cause fruit drop.
The vegetative growth and reproductive growth of fruit trees, although orderly, also overlap; branch growth, flower bud differentiation and fruit growth, they have a close relationship, and there is a certain contradiction of nutrient competition.
Fruit tree flower bud differentiation is mostly in the slow growth period of new shoots or after stopping growth, although the branches are strong and the single leaf area is large, which provides a material basis for fruit growth and flower bud differentiation, but excessive growth is not conducive to fruit growth and flower bud differentiation. It can be seen that the growth and development between the two is based on a balanced and reasonable relationship.
There is also competition between the reproductive organs of fruit trees, if there is too much flowering or fruiting, the nutrient consumption of the tree body will also increase, often can cause serious flowering and fruiting, and ultimately reduce the yield affecting the income. Different fruit trees, there will also be fruit growth and flower bud differentiation between the interaction between, the fruit tree flower bud differentiation and fruit growth overlap time is short, the flower bud differentiation has little impact on the flower bud differentiation, it is not easy to appear the phenomenon of size years; and the kernel fruit tree, fruit growth and flower bud differentiation at the same time for a long time, that is, the time of overlap between the two at the same time, fruit development has a large impact on flower bud differentiation, and it is more likely to appear large and small years.
The vegetative growth and reproductive growth of fruit trees, the two influence each other, but also have a "delicate" relationship, master and understand their own fruit trees, applied to the actual planting of fruit yield, tree robustness and other significance is very large; but also the fruit farmers should master the technology, in order to achieve high yield and quality, long-term stable production to provide protection.
