How to cultivate American red maple seedlings correctly

Roots are the basis for the growth of all plants. Only when the roots are healthy, can the nutrition of plants keep up and let them grow healthily and healthily. Let's take a look at it.

Factors affecting the Survival rate of American Red Acer seedlings

The root is the key to affect the survival rate of American red maple cuttings, whether it is container seedlings or bare root seedlings. The root system should have obviously strong secondary roots, thick and sturdy at the same time, so that the survival rate can reach 100%, while the survival rate of weak roots is very low, even if there are long roots. In that year, the seedlings of American red maple grew new branches, and the survival rate of leaves with normal growth was the highest.

The taller and thicker the new branches, the better. At that time, the new growth branches of American red maple seedlings reached more than 0.8 meters, which belonged to special-grade seedlings, which could not be achieved by general cutting techniques and cultivation techniques. If a very thin branch and several small leaves grow, it means that the root system is very weak and the survival rate must be low.

At that time, the seedlings of the American red maple did not grow new branches but the top buds were full, which did not affect the survival rate, but the root system must be developed, otherwise the survival rate would not be good either.

In addition to paying attention to the roots of the seedlings, only systematic pruning before planting and regular pruning after planting can make the red maple grow more luxuriantly.

Pruning of American red maple seedlings before planting

1. The roots and crowns of American red maple seedlings should be trimmed before planting, and the split, diseased and overgrown roots must be cut off to ensure the original natural posture of American red maple seedlings.

2. If the cut (or saw) is larger than 2CM, it must be treated with anticorrosion.

3. The fixed trunk height of the street tree should be 3m, the American red maple can be set at more than 2.5m, all the lateral branches below the first branch point should be cut off, and the branches above the branch point should be thinned or cut short as appropriate.

4. Tall deciduous trees, such as American red maple, should retain the original tree shape and be thinned properly, and the retained main and side branches should be cut short on the robust buds.

5. It should be noted that if the American red maple is planted as a street tree, the most suitable height is about 3m.

Planting of American red maple seedlings

Planting and planting: the tree pit should be dug, the diameter should be 1/3 larger than the root width of the seedling, and the cinder, lime and other sundries in the pit should be removed to facilitate the tree to take root and grow. The plant row spacing should be determined for the purpose of cultivation, and the plant row spacing must be straight and symmetrical to minimize errors; the tree must be vertical up and down, not askew; when the bare root seedlings of American red maple are planted, after burying the soil to a certain depth, the seedlings should be gently lifted upward, and then buried and lifted 3 times until the seedling depth is appropriate, and then the pit soil will be pressed and watered. When planting seedlings with soil balls, it is necessary to measure whether the depth of the pit is consistent with the height of the soil balls, and the backfill should be stepped on with the filling, but the soil balls should not be smashed.

Maintenance and management: American red maple transplant maintenance management is very important, generally must be watered at least three times, and to be thoroughly watered, insufficient to replenish water, to pay attention to the root soil after watering, to wait for the tree sprouting, conditional 1murf two days to spray water, so as to speed up the growth rate of new buds, and pay attention to new shoots vulnerable to aphids, dry weather timely observation spray, to often weeding loose soil. In terms of fertilization, base fertilizer should be applied at the bottom of the tree pit when digging; after planting, barnyard manure or chemical fertilizer can be used, ditch or hole fertilizer can be used to promote its growth.

American red maple is as red as the sea. High-quality American red maple can not only be used for landscaping, as street trees, decorating courtyards, etc., but also for afforestation to form a beautiful maple sea, so it is worth planting.
