Problems solved by technology
[0005] In view of the current extreme weather conditions in the Turpan-Hami Basin, the existing irrigation technology cannot guarantee the water-saving and high-yield demands of grape production in the Turpan-Hami Basin
Single drip irrigation cannot protect the impact of dry and hot wind on the grape growth process, and pure micro-spray irrigation cannot achieve satisfactory water-saving effects in the climate of the Turpan-Hami Basin

The invention belongs to water-saving irrigation technical means superposed by drip irrigation and micro sprinkling irrigation, in particular to applicable to the irrigation of grapes in extremely dry areas. The invention comprises a water-supply system installed in the field, a drip irrigation system which is connected by water pipes and paved in the field, and a micro sprinkling irrigation system suspended under the grape shed. The invention is specially applied to grape irrigation in the extremely dry areas; the structure is reasonable and the use is convenient; and the invention can ensure that crops can not be disoperated by disastrous weather on the basis of effective water conservation and can improve crop yield with favorable irrigation effect.
Description
technical field [0001] The invention belongs to the technical field of water-saving irrigation, and relates to a water-saving irrigation technical mode in which drip irrigation and micro-spray irrigation are superimposed. Background technique [0002] Dry and hot wind is the weather with high temperature and low humidity accompanied by a certain wind force. It strengthens the transpiration of plants, imbalances the water balance in the body, hinders or destroys photosynthesis, and abnormally transforms organic matter. The Turpan region is one of the areas with severe dry and hot winds in Xinjiang and even the whole country. The dry and hot winds are frequent in the area, and the dry and hot winds also have varying degrees of impact on grapes, cotton and melons. It can cause cotton flower buds and young bolls to fall off, grape fruit grains to decrease, and melons to fall off. The female buds of the species are dry and not strong, resulting in a large area of crop yield red...
