Review of Research Progress on Micro Rainwater Collection and Planting Technique

The research status of micro rainwater collection and planting technique was reviewed in terms of the ecological effect,strip shapes and rainwater-catching models,and the relation between rainfall and crop productivity of micro rainwater collection and planting technique.Based on these,there still existed a number of problems in the current micro rainwater collection and planting technique research.It is necessary to study and determine a basic general model of area ration deeply,to estimate appropriate rainfall range of micro rainwater collection and planting technique,and to make unified technical standard and operation method that adapts homologous area.As a whole,the technique would be widely used in arid areas,which would be an important way to improve rainfall use efficiency and increase crop yield,as well as reduce soil erosion and soil and water loss.
