Description
Technical field
The invention belongs to irrigation technique field, be specifically related to a kind of root-divided alternative irrigation using sulfur-bearing bitter and fresh water
Method and in the application of plantation North America, salt-soda soil Chinese juniper.
Background technology
Water is to maintain human survival and develop indispensable resource, is the important thing realizing human social
Matter basis.At present, shortage of water resources is as population, environment, energy problem, and it is four big that oneself becomes that a lot of countries and regions face
One of crisis, sets up a water-saving society, improves water resource utilization efficiency, ensures that the sustainable development of water resource is very urgent.Root
According to nearest estimation, China's freshwater resources account for the 8% of world's total amount, and China's gross amount of water resources is the abundantest, and total amount is 2.8
× 1012m3, wherein surface water is 2.7 × 1012m3, and subsoil water is 0.83 × 1012m3, but China occupancy volume per person is notable
Less than world standard, China's water resources ownership per capita is 2400m3, the about world 1/4 per capita, comes the 121st, the world,
One of 13 countries being listed in hydropenia.From the point of view of China socio-economic development, water resource is own through connecing rapidly
The upper limit of nearly bearing capacity, shortage of water resources problem, China's agricultural and the restraining factors of socio-economic development will be increasingly becomed.And
And in recent years due to the unreasonable development of water resource, precipitation is little and evaporation capacity big, and the soil salinization increases the weight of, and causes big portion
Region-by-region desertification of land area constantly expands, and the increase of agricultural irrigation water improves groundwater level.Of water resource itself
Irrational exploitation are added in shortage, cause China's water resources crisis more to be drilled the heaviest.
Existing irrigation water is in the majority with fresh water, and current freshwater resources usage amount is limited, and Appropriate application bitter is irrigated into
For the major subjects of at present research, there is following defect in existing irrigation method:
1, using existing irrigation method, root system of plant adapts to ability, in the soil that conditions of existence is more severe in environment
Growing way is poor；
2, using existing irrigation method, plant root growth speed is slow；
3, using existing irrigation method, every mu of irrigation water capacity height, water resource waste is serious.
In summary, prior art there will naturally be inconvenience and defect in actual use, it is therefore necessary to improved.
Summary of the invention
For solving technical problem present in prior art, the present invention provide a kind of use sulfur-bearing bitter and fresh water point
