Water-saving Ground Cover--Dianthus oxyphylla
Most areas in northern China are resource-based areas with severe water shortage, and the amount of water resources per capita is less than 300m3, which is only 1 / 8 of the national average and far below the lower limit of 1000 cubic meters per capita in the world. With the vigorous development of landscaping, the water consumption of landscaping is increasing, which is more and more contradictory to the shortage of water resources in northern China.
Phyllostachys cuspidata has good drought resistance and is a good water-saving plant material in landscaping. It is estimated that the annual water consumption of Carnation is only 0.3 tons per square meter, and it can still be evergreen in the dry season, which greatly reduces the cost of greening and maintenance. In addition, the pointed-leaf carnation overcomes the shortcomings of other carnation that its branches and leaves are wide and easy to lodge, its branches and leaves are delicate and dense, and the plant height is only 10 cm. Closed flat can not be pruned, the appearance is like Kentucky bluegrass lawn, forming a thick grass blanket on the ground, the landscaping effect is very good.
In addition to the characteristics of water-saving and drought-resistant, fast-growing and trampling-resistant, sharp-leaf carnation can also enjoy flowers in May and June every year. In some areas with good microclimate in the north, the sharp-leaf carnation can remain evergreen in winter. In addition, in the growth process of Phyllostachys pubescens, we should pay attention to the use of some chemicals to prevent the occurrence of diseases such as blight.
