(5) combination accessory method embodiment is irrigated in this water saving
Retaining is held concurrently, and fertilizer tank design is concrete to be implemented: around every chestnut, bury 3 in infiltrating irrigation jar underground, the position on the same circumference in tree crown 2/3 place, 120 ° of angles.Ooze each 15～20Kg of jar water capacity.The infiltrating irrigation jar is fired by traditional handicraft, and also available plastics are manufactured.Punch several at the infiltrating irrigation can body, and position middle part, bottom is respectively located on the upper side.The aperture is 1cm, and each aperture clogs gently with cotton thread, the jar mouth 2-3cm that is above the ground level when burying underground, rainwash enters and causes alluvial in the jar when preventing heavy rain, and a jar mouth covers with plastic film after the fills with water, to reduce evaporation, can adopt artificial backpack mode to inject water, but condition better also pipeline pour water.This water tank is in energy retaining in rainy season, and can seep water dry season by aperture, plays water regulating function preferably.This method is applicable to the orchard of knob water scarcity non-irrigated condition, is suitable for doing assorted fruit economic forest especially.
