How to plant maple trees

Every late autumn, the red maple leaves become a beautiful scenery, its beautiful trees, beautiful leaves, can be used as shade trees, street trees, or companion trees in landscape architecture. So, how to plant maple trees?

I. Woodland selection

The afforestation land should choose sunny slope or semi-sunny slope gentle slope forest wasteland and sloping farmland with deep soil layer, fertile soil and good drainage.

II. Land preparation

Soil preparation directly affects the conditions of light, temperature, water, fertilizer and gas needed for afforestation seedlings, which is the key to improve the survival rate and growth of seedlings. Acer truncatum has strong adaptability, which can not only build flake and block pure forest, but also be mixed with Platycladus orientalis, Pinus tabulaeformis, Pinus tabulaeformis, Larix principis-rupprechtii and other tree species. Therefore, banded or burrowed soil preparation is adopted in consideration of soil and water conservation and making full use of space. Generally, banded soil preparation is adopted in gentle slope zone, with a bandwidth of about 1m, while in woodland with thin soil layer and steep slope, burrowing soil preparation is adopted, and the diameter of planting hole is 1500px and deep 1250px. Spring afforestation is soil preparation in March, and autumn afforestation is better from July to August.

3. Planting

It can be planted in early spring or late autumn and early winter, and it is better in spring. Burrowing, cutting off the broken root, injured root and overlong root system before planting to facilitate the healing of the hairy lateral root. When planting, it is carried out in accordance with the requirements of "three burying, two treading and one lifting seedlings". First, fill the topsoil and bury the roots. when the soil is filled to about 2 / 3, lift the seedlings up gently to make the roots of the seedlings stretch, and then bury the soil in layers and step on the seedlings, so that the seedlings can reach the depth required for planting. The planting depth is 2~75px above the rhizosphere. After planting, the root water can be irrigated where there are conditions, so that the root system is in close contact with the soil.

IV. Field management

1. Weeding

In order to promote the growth of seedlings, the young forest stage loosens the soil and weeds twice a year. The first time was in late April, and the second time was in early August, combined with weeding, loosening soil 3~125px, and expanding tree holes from planting holes to promote root growth.

2. Fertilization

In the juvenile stage, available nitrogen fertilizer was applied 2 or 3 times from early May to early August, supplemented by phosphorus and potassium fertilizer, and winter fertilizer dominated by organic fertilizer was applied in late September combined with deep soil improvement. During the adult fruiting period, basal fertilizer is applied every year in the dormant period, soil topdressing is carried out during the growing period, and sometimes extra-root topdressing is applied. The effect of base fertilizer is better before the leaves turn red or yellow every autumn, mainly farm manure and cake fertilizer, and can also be applied with compound fertilizer in autumn and winter. Soil topdressing was applied 3-4 times a year, mainly nitrogen and potassium, and extra-root topdressing was carried out many times during the growing period.

3. Shaping and pruning

It can be done in winter or summer. Winter shearing is pruning from late autumn to the following spring before sprouting, which is suitable in early spring, with short cutting, branch thinning, retraction and flat stubble, while summer pruning is from sprouting to defoliation in autumn, including sprouting and de-sprouting, heart-picking, taking branches and pulling branches.

Prevention and control of diseases and insect pests

The common diseases are brown spot and powdery mildew. When the disease occurred, it was sprayed with 50% carbendazim wettable powder 800-1000 times, once every 10-15 days, 2 times in a row.

The main insect pests are Huang Xi E and Anoplophora glabripennis. The control of Huang Xie is generally eliminated in late autumn to early spring combined with ploughing the soil and digging pupae, or 1000 times of fenitrothion emulsion is sprayed at the initial stage of larval occurrence. For the control of Anoplophora glabripennis, the larvae of tree stems can be sprayed with 150 times of 50% fenitrothion EC for eggs and larvae that have not yet entered the xylem. For the seriously harmful young trees, it is better to cut down and burn them from the base, or to inject 40% dimethoate EC 100-200 times into the cavities, and then plug the hole with soil.

Maple and other autumn leaf trees or evergreen trees, set off each other, can increase the beauty of autumn color, interested friends can try to plant.
