Energy-saving consumption-reducing efficient water infiltrating irrigation method

Abstract

The invention discloses an energy-saving consumption-reducing efficient water infiltrating irrigation method. The method includes the steps of burying an infiltrating irrigation belt 35-40 cm deep in a farmland, deeply applying fertilizer or particle organic fertilizer in a farmland plough layer, sowing seeds in 15-20 cm deep, and completing the infiltrating irrigation belt, deep seed sowing and deep fertilizer applying work at a time in the farmland through an agricultural machine. The method has the advantages that useless evaporation of surface water is effectively reduced through buried type infiltrating irrigation; infiltrating irrigation is large, flow is large, water irrigation is rated, water consumption time is short, and energy consumption is reduced; the farmland is not covered with mulching film and is free of pollution; deep fertilizer applying and seed sowing are beneficial for crops to absorb water and nutrients in deep soil.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for energy-saving and consumption-reducing high-efficiency water seepage irrigation. Background technique [0002] According to water conservancy statistics, agricultural irrigation water in Xinjiang accounts for 90% of the total water supply, which is much higher than the national average of 67%. Agricultural water consumption accounts for a large proportion, and it is a major water user in various industries. Management" requirements do not meet. Therefore, to effectively reduce the proportion of agricultural irrigation water, improve the efficient water use of agricultural water resources and irrigation water utilization efficiency, as well as energy saving and low consumption of irrigation, and promote the harmonious development of economic society and ecological water environment, for this reason, vigorously developing agricultural high-efficiency wa...

Problems solved by technology

[0012] Step 1. In view of the long time and high energy consumption of drip irrigation under the film, which is not conducive to energy saving and consumption reduction, agricultural machinery operations are used to lay buried infiltration irrigation belts at one time, and infiltration irrigation is adopted in the soil plow layer. The soil cultivation layer with a depth of 40cm in the irrigated farmland, implements a large flow rate of 3.0L / hour for each irrigation, and a large irrigation quota of 50m 3 / mu, the irrigation time is 4.5 hours, the number of irrigation times during the crop growth period is 6 times, the average irrigation interval is 20 days longer, and the irrigation water time is only 27 hours during the whole growth period of the crop;
