Soil improvement of Cornus officinalis

For dogwood woodland, the operation of turning and pressing green manure should be done well, which can not only reduce soil water evaporation, store water and preserve soil moisture, but also increase the content of soil organic matter and fertilize the soil. For the planting land with large slope, we should do a good job of tree plate soil cultivation, which can prevent water loss, so that nutrients can ensure normal growth and development.

First, turn over green manure

From late June to late July, combined with mid-ploughing and weeding, weeds and small shrubs near the tree plate were removed or harvested, and covered with grass in the vertical projection of the tree crown, with a depth of about 15 cm, a radius of 0.5-1 m and a thickness of 10-20 cm.

The weeds in the woodland of Cornus officinalis can improve the soil and increase the content of organic matter, so it is forbidden to spray herbicides or plant growth regulators during the growth period.

Second, cultivate the soil on the tree plate

forty-five. The above slopes will be cultivated from November to December. With the trunk as the center, at the edge of 50-60 cm from the rhizome, a round mound is built with stones, which is horizontal to the base of the trunk. The humus and soil are mixed and filled, and the soil is slightly higher than the edge of the oyster. During the dormant period, combined with soil cultivation and fattening, we should constantly repair the tree plates washed by Rain Water.
