How do the octagonal trees protect leaves
The lifespan of the octagonal tree leaves is generally 1-3 years, and the saplings and strong trees have longer life spans, and the old trees and the diseased trees have shorter life spans. Taking appropriate measures to protect the leaves is of great significance to the growth of the tree and the increase of its yield.
First, science and fertilizer. The organic compound fertilizers with a large amount of elements such as constant, medium, and trace elements have a great effect on the growth of the leaves. One can have strong leaves, that is, the thick green leaves become thicker; the second can ensure leaves, that is, extend the life of the leaves. Single Application of binary or ternary inorganic compound fertilizer leaves, green color but not thick nor thick.
Second, rational fertilization. According to the growth characteristics of the octagonal tree, fertilization should be based on shallow application of thin and thin, mainly to maintain a balanced supply of nutrients throughout the year, avoid deep trench fertilization, avoid heavy fertilizer, avoid fertilization under drought and water shortage, otherwise it will be affected by the roots Causes the leaf to decline or cause defoliation.
Third, spray surface fertilizer. Foliar fertilizer has obvious effects on strong leaves and leaves, especially in the winter and spring season when the fallen leaves are relatively serious. Spraying 2-3 times foliar fertilizer can reduce leaves. Foliar fertilizers should be organic or compound-based, such as high Meishi, Xinzhisu, Feiyu, etc.
Fourth, strictly control the use of inhibiting hormones and components. Most inhibitory hormones have a certain effect on promoting flowering, flowering and fruit protection, but they also have some damage to the leaves and should be used with caution. It is generally advisable to use no more than 3 times throughout the year. The concentration should also be strictly controlled. The amount of spray should be sprayed until the leaves are moist but not dripping. It is best to add foliar fertilizer with spray to reduce the damage to the blade.
Fifth, trim. Excessively shaded and dense leaves only consume nutrients but do not produce nutrients. The life span of these leaves is relatively short, and the branches that should be planted should be cut off. But don't cut it all, because these branches can also bear fruit.
Six, pest control. Anthracnose, canker, soy, scale insects, aphids, mites and other pests all affect the leaves first, or cause yellow leaves, rolling leaves, fallen leaves, or reduce the life span of leaves. Therefore, various pests and diseases should be prevented and treated in time.
VII. Water supply. Long-term drought will cause dehydration and curling of the leaves, and even a large number of fallen leaves, and conditions should be timely irrigation or watering.
Eight, reasonable fruit. The fruit load is too large, beyond the reasonable load of the tree, and has a negative impact on leaves, tree vigor, and the following year's yield. After the first physiological fruit drop, excessive fruit should be removed.
