Background technique
Loess plateau is one of big eugenic area of China's apple two, and Apple Industry has become the pillar industry in loess plateau, passes
The soil management mode of system causes orchard soil water regime to be degenerated, and fruit yield decline, quality deteriorates.Result of study shows:
Loess plateau 14 years or more apple section 3-9m soil moisture in layer all substantially close to the field wilting moisture of local soil, apple
The strong transpiration of tree and strong evaporation consume annual rainfall infiltration amount, and constantly utilize the effective water storage of soil, promote
It is further dried into deep soil, forms geobiont and utilize type desiccation layer.The evolving trend of the desiccation layer with the age of tree increase
And enhance, after fruit tree growth is to certain time limit, this drying kinetics process terminates substantially, and soil moisture content touches the bottom.
Thereafter, moisture required for fruit tree growth and yield composition is transferred all by rainfall, and the pondage capacity of Soil Reservoir is lost, fruit
Tree yield is inevitably fluctuated with the natural trend of year border rainfall.It is statisticallyd analyze according to 28 years output of the fruit tree, soil desiccation
After layer occurs, larger fluctuation is presented with the natural trend of year border rainfall in output of the fruit tree, the yield of rear 13 annual about 20% by
Year border rainfall influence.Loess plateau apple cultivation area water shortage will affect the sustainable development of area's Apple Industry, since the whole world becomes
Warm, the phenomenon that drought, can be more serious.The water shortage problem of rain-fed agriculture region is solved, should be entered at present from the utilization for improving rainfall
