Large-row crop bubbler-trickle furrow irrigation water supply system and furrow irrigation water-saving cultivation method thereof

Abstract

The invention relates to a large-row crop bubbler-trickle furrow irrigation water supply system and a furrow irrigation water-saving cultivation method thereof. The large-row crop bubbler-trickle furrow irrigation water supply system comprises a water pump, a device for storing an irrigation water source and a water supply pipeline system, wherein the water supply pipeline system comprises a main and branch pipes, and the water supply pipeline system also comprises two capillary shunting water outlets which are equidistantly connected with each branch pipe through a T-shaped switching union. The invention also includes the large-row crop bubbler-trickle furrow irrigation water-saving cultivation method. The large-row crop bubbler-trickle furrow irrigation water supply system disclosed by the invention is applicable to sandy soil. The large-row crop bubbler-trickle furrow irrigation water-saving cultivation method disclosed by the invention increases the field flow velocity of irrigation, reduces the deep seepage and useless evaporation of irrigation water, effectively increases the moisture utilization efficiency of large-row crops, also increases the efficiency of fertilization, reduces the quantity of applied fertilizer, and achieves water and fertilizer integration; moreover, the temperature-increasing effect of ridging cultivation and the more optimized outside growth environment lay a foundation for the increase of large-row crop yield.

Description

technical field [0001] The invention relates to a furrow irrigation water supply system and a furrow irrigation water-saving cultivation method for a large crop, in particular to a furrow irrigation water supply system and a furrow irrigation water-saving cultivation method for a large crop. Background technique [0002] Drip irrigation is mainly used for drip irrigation in greenhouses and orchards; in contrast, field drip irrigation started relatively late and was only popularized in Xinjiang and other cotton-producing areas. In view of the drought characteristics in Xinjiang, drip irrigation under mulch is generally promoted. Drip irrigation belt, if the row spacing is less than 1 meter, consider laying a drip irrigation belt for two rows of crops, and if the row spacing is less than 0.3 meters, consider laying a drip irrigation belt for multiple rows of crops; from the current point of view, if my country’s agricultural land is reversed, it is also a development for food cr...

Problems solved by technology

Ridge farming and furrow irrigation technology at home and abroad are mainly used for wheat crops. For example, the prior art CN200910250193.5 discloses a water-saving cultivation method for ridge farming and furrow irrigation of spring wheat and malting barley in arid irrigation areas, including the following steps: (1) Ridging and sowing: Ridging specifications are ridge surface width 45-50cm, ridge width 2533cm, ridge height 15-20cm; sow on the ridge surface with a row spacing of 13-15cm, and a seeding rate of 350,000-500,000 grains / mu; (2) Furrow irrigation: use For irrigation in furrows, it is required that the irrigation furrows are not full of ridges. The irrigation period and frequency of irrigation are the same as the traditional method, and the amount of irrigation water is reduced by 50-100 cubic meters per mu compared with the traditional method; but this invention is only aimed at the production of crops such as spring wheat and malting barley

[0003] my country is short of water resources, and the water use efficiency of surface irrigation is low. Therefore, the research and development of furrow irrigation water supply systems and furrow irrigation water-saving cultivation methods for large row crops suitable for sandy farmland soils to save water, fertilizer, and increase production will have great potential for agriculture in arid areas. Sustained development is critical
