The invention provides an
orchard straw and surface soil double-layer coverage mechanical operating method and a covering
machine, and relates to the field of
straw resource utilization and the field of
agricultural machinery.
Straw is
cut into fragments, and an appropriate number of additives are added so that a coverage matrix can be formed. Plowing and cultivating are conducted on an
orchard, the spaces between lines or plants of the
orchard are covered with the
straw coverage matrix through machines, and meanwhile thin soil covering and pressing are conducted on a straw covering layer. Two schemes are adopted for the covering
machine. According to the first scheme, the covering
machine at least comprises five mechanisms, namely, a trailer, a straw material box, a straw matrix spreading part, a soil plowing and cultivating part and a soil covering roller, wherein the orchard soil plowing and cultivating step, the straw matrix covering step and the thin soil covering and pressing step can be completed; according to the second scheme, the covering machine at least comprises four mechanisms, namely, a trailer, a straw material box, a straw matrix spreading part and a soil covering roller. The method and the covering machine are suitable for drought orchards and particularly suitable for dwarf stock apple orchard mechanical straw covering, the orchard grass planting technology can be replaced, grass suppression, soil
moisture conversation and
water saving are achieved, soil organic matters are increased, the
soil temperature is regulated, the production cost is reduced, and the fruit yield and quality are improved.
