Summary of the invention

The object of the present invention is to provide and a kind ofly can be under water-saving prerequisite give soil the balanced filtration irrigation method that supplies water.

The said plant filtration irrigation method of the present invention, utilize seepage material 1 and source of irrigation water 2 to irrigate, wherein said seepage material 1 adopts fabric, said source of irrigation water 2 is no pressure water sources, no pressure water source adopts the surface water in tank, pond, ditch or the like, one end of seepage material 1 is immersed in the source of irrigation water 2, and the other end of seepage material 1 is laid in the middle of the soil layer of plantation plant.In actual use, said seepage material 1 preferably adopts nonwoven, can resist corruption; Said seepage material 1 can be done slabbing or band shape.

Adopt the said plant filtration irrigation method of the present invention, have the following advantages: because the fabric gap in the seepage material becomes capillary, the state that can make the irrigation water of being drawn form capillary water supply is transported in the soil, and is consistent with the capillary water yield of soil demand, improves the distribution consistency degree of water in the soil; Owing to not adopting pressure water supply to adopt natural water source, therefore can not produce because the pressure difference causes the wasting phenomenon in the water yield dispose procedure, the phenomenon that silt obstruction seepage material in the soil can not occur, so water and soil soil moisture conservation performance is good, is beneficial to the g and D of crop.
