The method used to plant the maple tree is simple and should be done with 80 to 100 cm, or 80 to 100 cm deep, and filled back with part of the topsoil, and then with fully decomposed or corroded compost mixed with the topsoil, then filled with 10 to 20 cm of good soil, so that the roots do not have direct contact with the fertilizer, so as not to burn the roots。
Refill ditches and caves should be carried out in such a way as to take advantage of the rainy weather and the wetness of the soil surface, and do not overfill the topsoil into the ditches and eight in order not to affect the activity rate. When planted, they cut off part of the long roots of the maple tree, and cut the roots of the wounds in order to heal the side root. Then put the tree in the middle of the planting ditch or den, so that the roots may stretch and spread evenly around it, and so that the seedlings may cross straight. Covered with topsoil near the roots, and then filled with it, they were used to lighten the platinum trees, and they were laid down in layers, so that the roots were so dense. Maple seedlings of the yuanbao are in the depths of the earth, which are generally equal to or deeper than the original earthmarks of 1-2 cm. The planting shall be followed by a permutation of water, which shall cover an additional layer of pine soil, and shall help to restore the seedlings。
In drylands, planting can take place by digging ditches and caves, and by planting when the soil is better. Plantation is followed by a collection of water around the stem with a long distance of 40 ~50 cm, with the greatest possible manual water。
In wind-dry drylands, shallow burials can be carried out by deep-drilling (cave-dwelling), i. E. Planting 15-20 cm of maple trees, which, after planting, determines a distance of 15-20 cm from the ground. This does not affect the growth of the larvae, but also contributes to the accumulation of rain and snow, and the protection of the cave walls against the wind reduces the evaporation of the water in the cave. In the north-west, around 15 cm from the cave, windshield can be repaired at the same time, significantly increasing the growth of the larvae and reducing the number of victims when pumping。
In the case of forested areas, the land should be prepared in accordance with the size of the slope. The first half of the year of the forest is good, with a minimum of one quarter in advance, with a normal fall-down and a full fall-down. The slope is above 25 °c, requiring the construction of an in-land high on the opposite slopes, which allows for the storage of rainwater and avoidance of wash-downs, and easy operation; the digging of trenches at 35 °c and above; the fragmentation of the terrain and the passage of steep slopes over the slopes, which allows the construction of fish puddles, which are laid in triangles, and the digging of semi-circle earth pits, and the construction of semi-circle earth along them. It would be preferable to dry off the seedlings after they have been planted, which would increase their productivity。
