For hawthorn woodland, the operation of overturning green manure should be well done, which can reduce the evaporation of soil moisture, preserve water and preserve soil moisture, increase soil organic matter content, and play a role in fertilizing the soil. For planting sites with large slopes, tree-disk cultivation work should be done to prevent water loss, so that nutrients can ensure normal growth and development.
First, turn green manure
From late June to late July, in combination with cultivator weeding, the weeds and small shrubs near the tree trays were removed or harvested. After the vertical projection of the tree crown, the grass was buried on the center of the trunk, and the depth of burial was 15 cm. Left and right, with a radius of 0.5-1 m, a thickness of 10-20 cm, and overburdened with earth.
The weeds in the woodland of Hawthorn can be used to improve the soil and increase the content of organic matter after being overturned. Therefore, herbicides or plant growth regulators must not be sprayed during the growth period.
Second, tree disk soil
45. Above the hillside, November-December will be built on the ground. With the trunk as the center, at the edge of 50-60 centimeters from the rhizomes, a circular shape is built with stones, and the horizontal direction of the trunk is parallel to the base of the trunk. The humus and the soil are mixed and filled with gram. The soil is slightly higher than the edge of the sculpture. . During the dormancy period, in combination with cultivation of soil, it is necessary to constantly repair the tree tray washed by rain.
