The invention discloses a mixed-
sowing method of
forage grass in a high altitude area of the
Three Gorges reservoir area, comprising
soil preparation before
sowing, mixed
sowing and
fertilizer application, wherein the mixed sowing means mixed sowing of
orchard grass seeds,
trifolium repens seeds and alfalfa seeds, and specifically comprises the following steps of: performing row-spaced drilling on the
orchard grass seeds and the alfalfa seeds, with row spacing of 0.3m; and uniformly sowing the
trifolium repens seeds among the rows of the
orchard grass seeds and the alfalfa seeds, wherein the dosage ratio of the orchard grass seeds to the
trifolium repens seeds to the alfalfa seeds is 1: (1 to 1.6): (1 to 1.6), in parts by weight. The leguminous
forage grass and gramineous
forage grass selected for the mixed-sowing of forage grass disclosed by the invention are featured with
heat resistance,
drought resistance and leanness resistance, and are mixed-sowed with each other, thus adequately utilizing
light energy and increasing photosynthates; additionally, the leguminous forage grass has a
high protein content and the
rhizobia of the leguminous forage grass has a function of
nitrogen fixation, thus remarkably increasing the yield of the forage grass, and improving the quality of the forage grass and
soil fertility, so that the advantages of the leguminous forage grass are very prominent. The method disclosed by the invention is simple and convenient, and simple in operation; and the artificial
pasture established by the method has the characteristics of
heat resistance,
drought resistance and leanness resistance.
