Abstract

The invention discloses an orchard underground hole irrigation method which belongs to underground irrigation. The orchard underground hole irrigation method is characterized in that 'fertilizer water holes' are buried in a root system distribution layer of a fruit tree, the 'fertilizer water hole' consists of four parts, namely an underlay plastic film (10), a water absorption and fertilizer storage material (9) mixed with a fertilizer, broken brick bats (8) wrapped by the water absorption and fertilizer storage material, an irrigation tube (3) inserted into the center of the broken brick bats. Each fruit tree is provided with 4-8 'fertilizer water holes', water is injected into the 'fertilizer water holes' by the irrigation tube (3) via a funnel and 10-20 L of water is filled into each hole. During fertilizing, the fertilizer water can be injected into the 'fertilizer water holes', thus the nutrient is directly transported to the root system centralized distribution area and fertilizer efficiency is improved. The method has the advantages of easily available materials, low production cost, water saving and drought resistance, not only can reduce evaporation from land surface and surface runoff, but also can prevent irrigation water from seeping to the deep soil layer; meanwhile the orchard underground hole irrigation method takes advantage of the 'hydrotaxis' and 'fertilizer anemotaxis' of the root system to confine the root system in or around the 'fertilizer water holes', thus improving the utilization rate of nutrient and water.

Description

(1) Technical field [0001] The invention relates to a water-saving irrigation method, which belongs to the field of orchard irrigation, in particular to an underground hole irrigation method for orchards. (2) Background technology [0002] Irrigation methods can be divided into surface irrigation and underground irrigation. Surface irrigation includes border irrigation, furrow irrigation, flood irrigation and low-pressure pipeline irrigation. Surface irrigation is easy to operate and requires less investment, but the irrigation quota is relatively large, the utilization rate of irrigation water is low, the workload of land leveling is large, and it is not conducive to soil and fertilizer conservation. Subsurface irrigation is an irrigation method in which irrigation water moistens the soil from bottom to top through soil capillary action. Infiltration irrigation belongs to a kind of underground irrigation. Its advantages are direct water supply to the root zone, high water...
