The high yield and stable production of fruit trees, which contains many important factors, but the protection of leaves is the top priority.
As we all know, a leaf is a small nutrition processing plant. If the leaves fall off prematurely, then fruit growth will become a passive source of water. At the same time, the differentiation and even formation of flower buds will have a great negative impact on the accumulation of whole tree nutrients. The high production and stable production in the coming year will be turned into bubbles.
Fertilizer management is an important foundation for high and stable production. It can thicken leaves, increase fruit size, and increase tree vigor. However, once the leaves are affected by some negative factors and fall off prematurely, photosynthesis will certainly weaken and the tree's potential will gradually decline. Even if there is sufficient soil and water, it will not be stable in the coming year, let alone yield. The early years of deciduous trees caused by continuous young trees are not necessarily inadequate for fertilizer and water management. From this point of view, the protection of the blades plays a decisive role in the factors of high production stability.
Ventilation and light transmission are important prerequisites for high and stable yields. It can enhance the activity of leaf cells and increase the leaf stress resistance. Improve the whole tree nutrient storage rate, but also can effectively improve the late fruit surface color. If the leaves fall out early, nutrition is produced, and accumulation is stagnant, even if it is a single plant, the branches will see light and may not bear fruit in the coming year. Even if there is a flower, it may be unrealistic. This year, it was generally spent more, but later in the tree's middle and lower part, there were several factors, of course, but a large part was caused by falling leaves earlier this year. It can be seen that, among the factors of high yield and stable production, compared to air and light, leaf protection has an unparalleled status and role.
Reasonable load is a necessary condition for high and stable production. It can increase the fruit and enhance fruit tree fruit stamina. It is of positive significance to promote the remaining nutrient accumulation in fruit trees and extend the commercial life of fruit trees. However, if leaves are premature, even if the amount of fruit in the year is small, it may not be in the coming year. From this point of view, blade protection is superior to reasonable loads in high-yield and stable production. Of course, the leaves fall early and early, light and heavy, resulting in varying degrees of fruiting in the coming year, but a thousand words, the imprint of the decline in the production of leaves will infiltrate them.
Indeed, the high yield and stable production of fruit trees are the result of a combination of various factors. And all factors can not be replaced, but not dispensable. Here is a simple comparison, aiming to clarify that the protection of the leaves is nothing more than nothing.
First, increase tree vigor and improve blade quality.
Second, the air and light and strive to strive for direct leaf or oblique illumination time 4 hours a day.
Third, the appropriate amount of fruit to ensure that the number of leaves for single fruit more than 36. Slow down the negative effects of fertilizer, leaf, fruit and leaf on the leaves.
Fourth, to strengthen the prevention and control of leaf pests and diseases Before the rain spray protection agent, after the rain treatment agent. The drug is administered once in 15 days, leaving no gaps. Especially in hot seasons, timely tonic after rain. The prevention and control of brown spot, spotted larvae disease, and ticks and leaf miners should be given priority. Make sure the leaves live healthy.
Fifth, regular quantitative leaf spray fertilizer This can not only actively and effectively enhance the vitality of leaf cells, improve its ability to resist cold and drought, resist pests and diseases, and delay leaf senescence. But also can actively and effectively improve the whole tree's nutritional level.
6. Try to avoid artificial damage and mechanical damage to the blade. If there is a strong convective weather such as hailstorm and strong wind, the leaves must be sterilized and sprayed immediately to restore the tree vigor and leaf function as soon as possible, and strive to be prepared and intact.
