Where is the best place to plant Golden Maple?
Comprehensive analysis of where to plant Golden Maple and the growing environment of Golden Maple trees. Next, the editor will introduce some knowledge about growing flowers to netizens.
Maple trees, also known as Acer truncatum, are deciduous large trees with strong trunks and can reach up to forty meters in height when mature. They have graceful shapes, and their leaves turn from light green to yellow in autumn, becoming an indispensable beautiful landscape in garden and park greening. They are widely used in garden greening. In addition, the beta-carotene contained in maple leaves has high edible value and also has great potential for medicinal development, which can effectively treat cancer and reduce high blood lipids. How to plant healthy maple leaves to benefit humanity? The following are some planting tips that I have summarized for everyone, hoping my suggestions can be helpful.
One, understanding the growth age of maple trees
The growth age of maple trees affects the physiological structure of the trees. For maple trees, there is a special node - three years. If they survive more than three years, they can grow smoothly; if less than three years, they are easily affected by diseases and pests and die. The secret is the special root structure of maple trees, which transports nutrients to the roots and accumulates nutrients in the roots, allowing the maple trees to maintain a nutrient consumption of about three years even when the root system is not very vigorous and is difficult for professionals to detect. Therefore, only by determining the planting duration of maple trees, can we predict their future growth trend.
Two, reasons for poor growth of maple trees
If maple trees survive their crucial three years, can they grow healthily? It cannot be hundred percent sure that they can survive successfully, the key is to see if their roots can really absorb nutrients. The specific reasons come from the following aspects:
1. Difficulty in root respiration
In tree planting, there is a saying among the people that "deep roots make茂 trees", so for maple trees with fleshy roots, ensuring the ventilation of the roots is crucial to grow strong new roots. Maple trees have existed since the Mesozoic era and have gone through historical changes, remaining only in our country, from Shenyang in the north to Guangzhou in the south. Because the species is old, the roots are very strong and the trees are entangled with roots when mature, requiring a lot of water. If the surrounding soil is alkalized or compacted, air circulation is difficult, and the oxygen content in the roots decreases. Planting the roots too deep hinders the respiration of other parts, and excessive watering creates an anaerobic and closed environment, obstructing the respiration of the maple tree roots. Over time, new roots萌芽 less, and the old roots that have grown tend to rot, causing the maple leaves to have weaker vitality and enter a dormant period of poor growth.
2. Low-lying terrain
Maple trees, as ancient plants, have a lot of water in their flesh, are drought-resistant like cacti, and are afraid of waterlogging. If you see large areas of maple trees in cities, they must be planted on hills or relatively flat land, because if maple trees are planted in low-lying areas such as lawns, root积水 will occur, leading to root rot. After the roots begin to rot, the roots will be unable to absorb nutrients from the soil and carry out autonomous respiration, the roots will be unable to supply nutrients to the upper leaves of the maple trees, the leaves will become thinner and thinner, the color will become more and more yellow, until the nutrients are consumed, and the life of the plant will come to an end. There is no big problem in dry and hot weather, but it is difficult to discharge water in case of heavy rain. Moreover, some enterprises plant maple trees on lawns to improve community greening, which is absolutely not allowed. Because lawns need to be watered a lot in the growing season, excessive water cannot achieve a dynamic balance between lawns and maple trees, and ultimately, the maple trees suffer, that is,积水 and root rot.
3. Few fibrous roots
The roots of trees are divided into main roots and fibrous roots, together contributing to better growth and development of trees. However, the main function of the main roots is to fix the body of the tree and make it root more firmly in the soil, while the fibrous roots mainly absorb nutrients. Therefore, if the number of fibrous roots is insufficient, during the high temperature season of July and August, sometimes high temperature and heavy rain, sometimes low temperature and little rain, water absorption and expenditure may be unbalanced, and the maple leaves will show a brown circle from the edge to the center, even extending to the veins, causing great harm to growth and development.
In addition, there are other reasons why fibrous roots cannot absorb nutrients: for example, not mastering the planting density of maple trees, the upper part is very thin due to the close distance, affecting the water absorption and breathability of the roots, thus affecting the growth of the fibrous roots of the maple trees.
4. Insufficient application of chemical fertilizers
Maple trees are fond of fertilizer and can tolerate it. They generally need to be fertilized 3-4 times a year. Scientific fertilization is an important part of the growth of maple trees. For young trees and adult fruit trees in small years, it is best to fertilize one month before Guyu, when the roots are most vulnerable, using fast-acting fertilizers as the main component and organic fertilizers as the secondary component, otherwise it is easy to burn the new roots. This helps to improve the fruit setting rate. For adult trees, fertilization is generally done about 5 days after the spring rain, and top dressing can be done for the roots in the evening.
Three, how to effectively solve the problem of poor growth
1. Preventive measures:
(1) Choose loose and flat planting sites
When preparing to cultivate maple trees, it is first necessary to avoid low-lying and waterlogged areas that are prone to root rot; avoid lawns that require a lot of water and make it difficult for roots to breathe; avoid ditches where the soil is too loose to root firmly; and avoid narrow greenery ponds that affect root growth. If possible, choose sandy soil, which is not only loose and breathable but also dry, making it suitable for maple tree growth.
Many people who do greening in communities do not understand the habits of maple trees and plant them in soil surrounded by concrete, which limits the growth space of the roots and affects root breathability, thus affecting the growth of lateral roots and new roots.
(2) Choose a suitable planting season
For maple trees, the best planting time is early spring and late autumn, when the trees are in a dormant period and relatively easy to survive when transplanted.
(3) Choose the right transfer method
Transplanting maple trees is the same as transplanting flowers. It is best to keep the roots with a soil ball to maintain the integrity of the root system, which is conducive to the recovery of the tree after the roots are damaged during transplanting. Tying the roots with straw ropes is the most common method for transplanting large trees, as it can ensure the integrity of the soil ball and prevent root damage. Although straw ropes are easy to rot, they can become nutrients that plants can absorb after entering the soil. However, the roots of maple trees are relatively fragile, so it is best to remove the straw ropes from the roots when transplanting maple trees. After being buried in the soil, they decompose like leaves and quickly become nutrients that plants can absorb.
(4) Choose a high-nutrient soil environment
Since maple tree roots require a lot of oxygen and are not tolerant of excessive watering, a shallow planting and high mounding method can be chosen when planting, which can not only help the roots breathe but also prevent root积水 during the rainy season.
(5) Choose an effective fungicide
The main purpose of choosing a fungicide is to prevent root rot, combined with root growth promoters to make the eggs of parasites die due to their weak resistance, accelerate wound healing, speed up the germination of new roots, and help the roots transport nutrients to resume normal growth. The specific operation is to use fungicides such as metalaxyl or carbendazim for root irrigation after transplanting maple trees.

2. Actual improvement measures
For trees that are already growing poorly, specific treatment methods should be taken to recover the losses caused. This can be done by increasing root air holes, improving soil, effective root growth, and fertilization to help.
(1) Increase air holes
For maple trees that are still not growing well after more than three years, the best way to ventilate is to add air holes to the roots. Buy a洛阳铲 or a punch tool from the market, and make five to eight air holes with a diameter of 8-10 cm around the soil ball, preferably 30-40 cm above the soil ball and evenly distributed around the tree diameter. The specific number is not fixed and should be adjusted according to the diameter of the tree trunk; the larger the diameter, the more air holes.
(2) Improve the soil
Why is it necessary to improve the soil? One of the direct factors affecting the poor breathability of maple tree roots is the heavy and sticky soil environment. To have better soil improvement ability, it is necessary to mix the sandy soil evenly. First, remove some of the soil around the soil ball of the roots and then return it to the soil for backfilling. In addition, the time to improve the soil should be chosen in autumn, about 30-50 days before the leaves turn yellow and begin to wither. At this time, although the stems and leaves of maple trees consume less nutrients, the roots are vigorous and have strong repairability, allowing the roots to recover quickly.
Tip: When removing the soil around the soil ball, try not to damage the fibrous roots and use a brush to remove the soil.
(3) Root growth and preservation
If air holes have been made in the root ball, it saves a lot of trouble. At this time, when灌根 with the medicine, the liquid can be directly poured into these air holes, adding fungicides such as metalaxyl and root growth promoters, diluting with water, making the medicine penetrate thoroughly, accelerating the germination of new roots, and conducive to the recovery of growth.
Tip: When diluting the root growth promoter with water, be sure to follow the instructions strictly; if the concentration is too small, it will not have the effect of root growth.
(4) Fertilize according to the season
Maple trees require different amounts and types of fertilizer in different seasons. In spring, apply leaf fertilizer with phosphorus and potassium compound fertilizer, using more for large trees and less for small trees. In summer, apply fruit fertilizer as early as possible, preferably in early July, applying about 0.5 kilograms of urea per tree. In autumn, apply body-building fertilizer, that is, farm manure, applying three to four times the annual yield. In winter, apply a heavy base fertilizer before and after the Spring Festival, using a deep ditch and applying soil manure and cake fertilizer, which is ideal.
Maple tree planting is limited to three years. If the growth is poor after three years, it is likely that there is a problem with the roots, such as soil compaction, low-lying terrain, and insufficient chemical fertilizers, all of which are causes of root hypoxia. We can prevent and effectively solve these problems by increasing air holes, improving soil, promoting root growth, and fertilizing according to the season, making full use of reasonable resources to control maple tree root rot and leaf curling problems and bring back the true beauty of maple trees in the golden autumn.
