Planting Methods and Techniques for Red Maple Trees
An introduction to the planting methods and techniques for red maple trees and the sharing of maintenance skills for green plants and flowers will surely be of help to you. Let's learn about it together!
I. Red maple seedlings are divided into two types according to different propagation methods:
1. Cutting propagation: More suitable for spring planting, its root system is mainly composed of horizontal roots. If planted in autumn, due to the large temperature difference and the cold winter, the seedlings will enter dormancy. Especially in the northern regions where winters are extremely cold, the survival rate of cutting propagation seedlings is particularly low!
2. Grafted seedlings: The characteristic of this type of red maple seedling is that the root system is mainly vertical because the rootstock seedlings are propagated by sowing seeds. The advantage is that they have strong resistance to various factors, such as cold and drought resistance. The disadvantage is that in windy conditions, the grafting joint is easily broken! Therefore, grafted seedlings are more suitable for autumn planting.
II. The germination rate of red maple is related to the following factors:
1. The planting time of red maple seedlings:
Generally, red maple seedlings planted in autumn have a later germination time because they have to go through a long winter dormancy before they can germinate normally in spring. If planted in spring, the seedlings usually germinate earlier. This is because the temperature rises quickly in spring, and if planted in mid-March in the northern regions, they can germinate within about 20 days.
2. The depth of planting red maple seedlings:
Generally, seedlings planted too deep have a later germination time. When the soil is exposed to sunlight, the soil temperature rises slowly, causing the roots to be exposed to heat later, and thus delaying the germination time. There is no such problem with shallow planting. As long as the temperature rises quickly in spring, the soil temperature will also rise quickly, and the shallow-planted seedlings will germinate soon.
3. The freshness of red maple seedlings:
If the red maple seedlings are purchased nearby, they are usually excavated quickly, transported over a short distance, and planted quickly, resulting in slow water loss and good freshness of the seedlings. Even if some large roots are cut temporarily, it will not affect their quick germination and survival. Conversely, if the seedlings are transported over a long distance, the rapid water loss after the roots are cut, combined with the long-distance transport, can cause some of the seedlings to "sicken," especially during the winter dormancy period. It is difficult for laymen to see any problems from the appearance of the red maple seedlings. After planting a large number of seedlings, it will be found that in the following spring, the red maple seedlings germinate very late and in limited numbers, greatly affecting the survival rate of the seedlings.
III. To improve the survival rate of red maple seedlings and ensure quick germination, efforts should be made in the following aspects:
1. Choose sandy soil for planting small seedlings:
Generally, red maple seedlings are first cultivated as small seedlings and then transplanted to larger ones when they reach a certain size. During the initial stage of raising small seedlings, choosing sandy soil for planting not only results in a high survival rate but also quick recovery. The characteristics of sandy soil include good ventilation, water permeability, and quick root warming. The disadvantage is that it has poor water and fertilizer retention, requiring frequent fertilization.
2. Special attention! Make sure to "plant shallowly":
Usually, regardless of the chosen plot, the deeper the red maple is planted, the less likely it is to germinate, especially for seedlings that are difficult to survive due to cutting propagation. Numerous practices have proven that the deeper the planting, the quicker the death.
3. Auxiliary management after watering red maple seedlings:
After planting the red maple seedlings, they must be watered with a flood irrigation method. As soon as the soil is slightly dry, workers should be arranged to straighten the seedlings and cover the roots with soil. Neglecting this can severely affect the later output rate of high-quality seedlings! Exposed roots that are not covered with soil can easily lead to poor survival rates!
4. Pay attention to adjusting the soil pH:
Since red maple seedlings belong to the slightly acidic type of seedlings, special attention must be paid to whether the soil alkalinity of the chosen planting site is too high. The枫林 has encountered a case where a nursery owner transported a batch of 3 cm diameter magnolia seedlings from Xiangfan, Hubei, over a long distance and planted them in different nursery plots. As a result, one of the plots had excessively high alkalinity, leading to significant losses! If a white "frost-like" substance appears on the soil surface after watering the red maple seedlings, it can be concluded that the soil alkalinity is excessive. In such cases, two solutions can be adopted: one is the use of "phosphate slag" produced by fertilizer plants, which has an acidic chemical property and can be applied extensively to the ground and plowed; the other is the use of large-packaged ferrous sulfate, which can be diluted and irrigated with water, both effectively improving soil alkalinity.
5. Prevent harm from underground pests:
If individual seedlings suddenly die after germination, it is necessary to observe whether it is due to underground pests. There are mainly three types of underground pests that harm the root systems of seedlings: grubs, ground beetles, and nematodes. These pests primarily feed on the roots of seedlings. If such a situation is found, it is necessary to purchase two types of pesticides from the agricultural market for extermination: one is soil bactericides and the other is phoxim preparations.
