1. Designing reasonable ditch and border dimensions and irrigation technique parameters leveling the land is an important water-saving and yield-enhancing method to improve the quality of ground irrigation, shorten the irrigation time and increase the irrigation efficiency. Combined with land leveling, change long border (ditch) for short border (ditch), change wide border for narrow border, design reasonable border ditch size and flow into the border (ditch), can greatly improve the irrigation degree of uniformity and irrigation efficiency. 2.
2, change the ground all wet irrigation for local wet irrigation will orchard traditional ground all wet irrigation to alternate ditch (border) irrigation or local wet irrigation, not only reduces the plant soil evaporation accounted for the proportion of the total evaporation of the farmland, so that the field soil water use efficiency can be obviously improved, and can be better to improve the permeability of the soil in the root zone of the fruit tree, enhance the root system deep rooting, and is conducive to the use of the deep soil root system, both water saving and water storage. Water storage, both water saving and yield increase double effect, worth promoting. In the apple, grapes on the research shows that take the border, alternate irrigation ditch, wet area can be reduced by 50%, water savings of up to 30% or more, yield increase of 5% -10%, the berry sugar content increased by 1.5% -2%, yield and quality obviously improved and improved. 3.
3. change a water release for intermittent water release to change the traditional ditch, border a water release irrigation for intermittent water release (also known as wave surge irrigation), intermittent water release so that the water flow was wave surge propulsion, because the soil pores will actively blockade, in the soil surface to form a thin blockade layer, the water flow propulsion speed. In the same amount of water irrigation, intermittent irrigation water flow forward speed for the continuation of irrigation 1-3 times, thus greatly reducing the deep seepage, improve the degree of irrigation degree of uniformity, so that the field water use coefficient of 0.8-0.90. 4.
4. take water conservation and moisture conservation membrane irrigation membrane irrigation is our country in the film cover cultivation techniques developed on the basis of a new ground irrigation method. It is the film to lay the method of bed, ditch all cover, realize the use of film water transmission, through the fruit tree irrigation hole infiltration to the fruit tree irrigation method. Because the irrigation holes only accounted for 1-5% of the irrigated area, the rest of the area mainly rely on the side of the seepage wetting, so the membrane irrigation is actually also belong to the local irrigation. Mulch cultivation and membrane irrigation techniques combined with water conservation, fertilizer, improve ground temperature, inhibit weed growth and improve fruit quality and other characteristics. Because membrane irrigation is a new irrigation techniques, there are many immature, imperfect places need further research.
