The invention discloses a sand-covering and soil
moisture preservation cultivation method for
dry land apple trees. The sand-covering and soil
moisture preservation cultivation method for
dry land apple trees comprises the steps of (1)
orchard location selection, (2)
fertilizer application, (3) sand laying, (4)
water irrigation, (5) other management and (6) sand replacement. The sand-covering and soil
moisture preservation cultivation method for
dry land apple trees is characterized in that according to sand laying in step (3), enough base
fertilizer is applied before sand laying, soil is ploughed as deep as 18-25 cm, soil lumps are crushed, flattened and raked, and a sunscreen net fully covers the
soil surface and is tightly attached to the
soil surface; after the base
fertilizer is cured, processed
river sand which is small in soil content and uniform in size is laid and pressed on a black wire net, the thickness of the sand laid within the range of 1.5-2 m of the
diameter of each
tree trunk is 3-5 cm, and the thickness of the sand laid in the other area is 1.5-2 cm. The sand-covering and soil moisture preservation cultivation method for dry land apple trees improves soil moisture preservation and heat preservation effects through a secondary covering structure, and is better in soil moisture preservation and heat preservation effect compared with an existing sand covering and soil moisture preservation method. Due to the two
layers of covering, the probability of freezing injury to the root systems of fruit trees in the
overwintering process is reduced, and good economical and
social benefits are achieved.
