Drip irrigation water-saving method for red dates in arid regions

Abstract

The invention relates to a mulched drip irrigation energy-saving method for red dates in arid regions, which comprises the steps of seeding, laying of a drip irrigation tape, mulching and grafting. In the method, can effectively reduce the evaporation of soil water can be effectively reduced, and salt and alkaline pressed by soil and soil moisture conservation are facilitated by considering the practical conditions of less rainfall and commonly serious salinization in arid regions and combining the traditional drip irrigation technology and the mulching measures according to the growth characteristics of the red dates. Shown by a great amount of experiments, under mulching condition, the irrigation period of date trees is prolonged to 15-16 days from 10 days under non-mulching condition, so that the growth demand of the red dates can be met and water can be saved by 50-55 percent; and the mulched drip irrigation method for red dates can save water by 50-55 percent in comparison with the traditional drip irrigation mode for each mu (mu is a unit of area). With the method, the technical difficulties of lack of water, salt damage, difficult wintering of large-scale forests and fruitsplanting under control conditions are solved, the wintering dead rate of fruit trees is reduced by 4-6 percent, thus being suitable for promotion of large-area forest and fruit engineering in arid areas, and providing a new concept for applying of the mulched drip irrigation energy-saving technology in forest and fruit industry.

Description

Technical field [0001] The invention relates to a water-saving method for drip irrigation under mulch of red dates in arid areas, belonging to a water-saving planting technology for forest and fruit, and is a water-saving measure for oasis agriculture in arid areas for large-scale red dates planting. Background technique [0002] Arid areas are characterized by scarce precipitation and strong evaporation, and water resources are the most important factor restricting economic development. However, with the development of society and economy, the development of oasis by mankind is intensified, the area of ​​oasis is expanding, the population is increasing rapidly, and the shortage of water resources has become the most prominent problem restricting the economic development of oasis. At the same time, the special climatic conditions in arid areas cause salt to accumulate on the surface along the capillary along with the strong evaporation of water, resulting in reduced crop yields; ...
