Stumping and rejuvenating method of ammopiptanthus mongolicus

Abstract

The invention discloses a stumping and rejuvenating method of natural ammopiptanthus mongolicus which belongs to rare or endangered species. An optimized implement way of the stumping and rejuvenating method of the ammopiptanthus mongolicus includes the following steps that at the end of winter and the beginning of spring, ammopiptanthus mongolicus populations are divided to be in stagger arrangement; vegetation coverage of a stumping area is more than 60 %; an area ratio of the stumping area and a reserved area is 1:2; the band width of the stumping area is 2 m; the band width of the reserved area is 4 m; a whole cluster is cut through sharp tools; the height of stubble is 0-3 cm apart from the ground; and the diameter class thickness of stump plants is 15.09-19.95 mm. The stumping and rejuvenating method of the ammopiptanthus mongolicus has the advantages of solving the problems that the ammopiptanthus mongolicus is easy to have problems of growth recession, dried-up to death and being endangered due to harsh environment and increasing ages, being simple in operating step, easy to popularize and capable of promoting growth of sprout tillers and new branches on root portions, promoting spontaneous recovery of the ammopiptanthus mongolicus, eliminating plant diseases and insect pests, greatly improving blossom and maturing rates due to the fact that the stump plant starts to bloom and seed at the second year and being capable of feasibly protecting the ammopiptanthus mongolicus which belongs to the rare or endangered species.
