First, summer fruit tree shaping pruning
Naturally growing fruit trees, canopy closure, dense branches, overlapping, overlapping, empty, empty tree vigor; poor light and ventilation, serious diseases and pests; yield is not high, prone to size and annual results, poor fruit quality; inconvenient Fruit harvesting, thinning and fruit thinning, and pest and disease control. Through reasonable pruning, young trees can speed up the expansion of tree canopies, increase branches, advance fruits, and increase yields in early stages, as well as cultivating tree structures that can reasonably utilize light energy, burden high yields, and obtain fruits of good quality; , can make the tree development is normal, maintain a good tree structure, the relationship between growth and the results of the basic balance, achieve high yields in successive years, and extend the fruit period as long as possible; aging tree through renewed pruning, can make the old tree rejuvenation, maintain a certain Yield.
By pruning, the canopy can be cultivated into a well-structured, solid framed, tidy canopy, and can meet the requirements of the cultivation distance. Reasonable pruning can make the new shoots grow robustly, and the vegetative shoots and fruiting branches are properly matched. Different types and lengths of shoots can maintain a certain proportion, and the result branches can be reasonably distributed. Robust shoots and sufficient flower buds are formed year after year, and the yield is high. stable. Reasonable pruning can make the fruit trees airy and transparent, the fruit quality is good, the size is uniform, and the color is bright.
The whole table pruning is an important measure in fruit cultivation techniques, but it must be based on good soil, fertilizer, water and other comprehensive management in order to fully prune the role of pruning; and must be based on tree species, species, environmental conditions and cultivation management Level, the use of plastic pruning technology, its role to play.
At present, there are more than 300 kinds of trees in fruit tree production. Although there are differences in the characteristics of the varieties, this large number of trees makes it possible to produce fruit trees in high yields. If we look at it dialectically, it is intangible. However, no matter how much the tree shape changes, it can make fruits and vegetables productive. There must be a dominant factor here.
The yield of fruit trees stems from a number of factors. In terms of trees, the leaves are extremely important. It is the carrier of chlorophyll, the receptor for light, and the processing plant for energy conversion. According to the needs of human beings, it is the main basis for fruit trees to obtain high yields, and it makes the existence of many fruit trees more reasonable. Is to make it the dominant factor in production. Practice has proved that if we remove all the leaves, no. Not only do you trim and leave all the leaves on the tree. The fact that the rational existence of hundreds of trees and various types of pruning and trimming techniques are ultimately unified in the adjustment of the blades and the utilization of light energy by the blades.
In the past, in practice, more emphasis was placed on how to prune fruit trees. Each producer should pay more attention to trimming the fruit trees. If your mastery of fruit tree pruning technology is to move from necessity to freedom, then when your pruning technique on fruit trees will move from liberty to necessity, it will gain greater freedom in the shaping of fruit trees.
Second, the summer fruit tree leaf surface adjustment
The pruning of fruit trees often pays more attention to yield and quality. In fact, the effect of pruning, as it says, is to adjust the output structure of the tree, rather it is to adjust the light conditions of the blade. The direct purpose of pruning is to make the overall distribution of the blades reasonable, and to try to adjust each blade above the light compensation point to obtain the maximum photosynthetic efficiency.
When we strengthen the management of fruit trees, we should emphasize the management of fruit tree leaves. The degree of utilization of light energy by the leaves on the fruit trees is related to the quality of the blades themselves, and the generation of high-energy blades interacts with light quality and light intensity. When we manage the leaves, we should be clear about the function of the seven leaves that exist on the tree.
1. Invalid leaves: leaflets growing at the base of the shoots, the net photosynthetic rate is low, the accumulation and consumption are flat, and its function is ineffective.
2. Low-energy leaves: Poor development of the leaves, poor nutrition, this leaf function is not high, but it can accumulate a little nutrition.
3. Oversized leaves: grow in the inner ridge, or grow too busy, incomplete development, leaf area is too large and thin texture, low light efficiency or high photosynthetic efficiency and consumption.
4. High-energy leaves: well-developed, medium-sized leaf area, thick texture, high practical efficiency.
5. The initial exhibition leaf: refers to the leaf that is initially unfolded at the top and consumes a large amount.
6. Expanded leaf: It has been expanded and needs to continue to expand. Although it is powerful, it is used for construction and it consumes much.
7. Color-changing leaves: Although the leaf turning stage has a strong function, its accumulation ability is low.
According to investigations, it is an important period for the formation of high-energy blades during the 30 days of fruit tree leaf expansion, especially during the 20 to 30 days after leaf development. Reasonable tree shape, the amount of nutrients accumulated in the tree body in one year, dynamic co-feed of fertilizer and water, and reasonable application of effective leaf fertilizer. Chemical regulation contributes to the formation of high-energy blades.
Simply put, the leaves of fruit trees contain chloroplasts. When the sun shines on the chloroplasts, the energetic photons impact the pigment molecules in the chlorophyll. After a series of changes, the light energy is converted into electrical energy. After the material is assimilated, carbohydrates are formed. To prune fruit trees, it is important to create a good lighting condition for the crown of fruit trees. Although fruit trees can carry out photosynthesis under normal light conditions, the photosynthetic intensity is low and the production of substances is less than the consumption of substances. As the light increases, the photosynthetic intensity also increases. When the light intensity reaches a maximum, the photosynthetic intensity will not increase. This phenomenon is called light saturation. This is the most productive nutrient. If the light intensity exceeds the light saturation point, although it can be absorbed by the leaves, it cannot be used for photosynthesis and a hot form is released. When the intensity is high and weak, the photosynthetic intensity also becomes lower. When the photosynthesis produces substances as much as the tree consumes, ie when the net photosynthetic intensity is equal to zero, the light intensity at this time is called the light compensation point. In a fruit tree that is not pruned, the leaves around the canopy are well lit, their light intensity is above the light compensation point, the leaves of the inner hall are overlapped due to multiple rushes, the light is insufficient, or the pruning is unreasonable, and the overall blade is unreasonable. The distribution did not adjust well, causing the internal enthalpy to be too airtight. The light intensity of most of the leaves was at the light compensation point. As far as the whole fruit tree is concerned, nutrients produced by external leaves are often consumed by the leaves of the indica, but they do not accumulate, and they add to the respiratory consumption of other organs. This makes it difficult to ensure their normal growth and development. Falling and falling fruit is heavier, yield is lower, and stress resistance is weak, and it will also affect the output of the next year.
Artificial cultivation of fruit trees, most of the entire process throughout the year should be managed, dominated. Its purpose is to get the ideal material accumulation. Let it produce as many high-energy leaves as possible, and adjust each blade to be above the light compensation point, and it is achieved by shaping and trimming the tree.
The growth, development, flowering, and fruiting of fruit trees are affected by many factors. But there are three main points. One is light, the other is temperature, and the third is fertilizer. In these three points, light is the energy source of the tree. If there is no light, fruit tree production is impossible. The temperature is the survival condition of the tree, and the fertilizer and water are the lifeblood of the tree. However, the growth and development of a certain part of the tree affects the growth and development of another part. These living conditions and the growth and development of various organs are interdependent and mutually restrictive. To manage a tree well, it is necessary to stabilize the dynamic equilibrium of the tree. This requires the normal growth and development of fruit trees, which is also the technology of our fruit tree management personnel.
