Different planting techniques of American red maple in different seasons

American red maple can be planted in spring and winter because of its strong vitality and adaptability, but its technical requirements are different in different seasons.

Planting techniques of American red maple in spring

Land consolidation: including deep turning and spinning. If there are conditions, we can apply organic fertilizer reasonably. Pig manure is applied according to 2 square meters per mu before soil preparation.

Planting: then plant according to a reasonable spacing between plants. The planting depth suggests that the ground should be level with the grafting interface. However, for the seedlings above the 10cm grafting interface, it is suggested that the planting depth should be equal to the original soil marks. Then step on it and water it thoroughly. Check the upright condition of the seedlings the next day and correct all the seedlings in time. And water it all over again on the third day. Can enter the normal management period in the future.

Planting techniques of American red maple in winter

False planting: if the local temperature is below minus 3 degrees Celsius, it is best not to plant the seedlings during this period. The method of pseudo-planting is to dig a pit 30 centimeters deep, put the seedlings into it and fill it with sand, and then water it. Then use leaves, hay or other anti-freezing measures for heat preservation. The advantage is breathable, covering a depth of about 30 centimeters.

Planting: the planting land needs to be turned over and the seedbed leveled. Irrigate thoroughly after planting, large permeable water (flood irrigation), and then check whether the seedlings are rooting, and those with exposed roots should be covered with soil in time. The seedlings are covered with soil in all directions according to the change of local temperature. The temperature warms up after the next spring, and the soil covered on the seedlings is removed in time so that it can have a good growth.

Seedling Management of American Red Acer

The main results are as follows: 1. After the American red maple seedlings are unearthed, the initial growth is slow, poor resistance should often spray water, maintain soil moisture, and remove weeds in time, while weeding, cultivate more soil as much as possible to prevent lodging.

2. When the seedlings grow to 5 centimeters high, the seedlings are usually fixed after irrigation. The seedlings are weakened, diseased and young seedlings are removed according to the spacing of 10 to 15 meters, and the seedlings are kept strong and tidy. If there is a lack of seedlings, transplanting seedlings with soil balls is carried out in rainy days.

3. When the seedlings of American red maple grow up to 10-20cm height, the seedlings can be planted directly in the nursery, or in nutrition bowls or tree seedling trays.

In April and early June, urea was applied in combination with watering, 15kg per mu, and urea 10~15kg per mu in the middle of July, and water was properly controlled in the later stage. If pests such as diamondback moth are found, 2.5% deltamethrin 4000 times solution can be sprayed for control.

5. The seedling height of American red maple can reach 0.6 million meters that year, and it can be replanted in the following spring.

Control techniques of Diseases and insect pests of Acer truncatum

The main pest of American red maple in spring is a small beetle, which lies out day and night, can not be seen during the day, and only comes out at night to harm seedlings. This pest has certain regional restrictions, which may not be found in other areas.

When insect pests occur, there will be a lot of small sieve eyes eaten by insects, accompanied by leaf shrinkage and yellowing. I don't know what kind of bug this bug is, it should be a kind of beetle, but it is very easy to kill, almost any kind of insecticide can kill it, and it is very seasonal, it only appears once a year, lasts about ten days.

For this pest to give priority to prevention, its prevention and killing is also very simple, only need to spray pesticides after 2 o'clock in the afternoon, have suffered insect pests and appeared leaf wrinkle yellowing, it is recommended to spray with some foliar fertilizer with the effect of stretching leaves. Prevention can also be used in spring sprouting water accompanied by pesticide irrigation, so that the seedlings absorb pesticides, pests eat any part of the seedlings will die.

Finally, I would like to remind you that although the evaporation in winter is small and the water demand of American red maple is relatively small, it affects the cold resistance of American red maple and its growth and development in the coming year. Therefore, in early November, the newly planted American red maple should be irrigated with water, that is, "frozen water", to ensure the normal growth of American red maple.
