The invention relates to combined grass seeds which are suitable for the recovery of the black beach vegetation. The combined grass seed series are as follows: (1) the combined grass seeds are formed by blending Stipa aliena, Leymus and Puccinellia tenuiflora according to different weight proportions, and are suitable for the revegetation of the secondary bare area in all black beaches and cold and high meadow areas which takes ecological restoration as the objective; (2) the combined grass seeds are formed by blending Festuca sinensis, Poa crymophila of Qinghai and Kentucky bluegrass of Qinghai according to different weight proportions and are suitable for establishing artificial pasture, which takes grazing utilization as purpose, on the severe black beach with a slope that is less than or equal to 25 degrees; (3) the combined grass seeds are formed by blending Elymus nutans, Elymusbreviaristatus of Qinghai and Qinmu NO.1 siberian wildrye according to different weight proportions and are suitable for establishing artificial pasture, which takes grass mowing as purpose, on the severe black beach with a slope that is less than 7 degrees. The combined grass seed series of the invention have extensionality and still have space for extending the combination with the development of research and productive practice. The combined grass seed series of the invention are suitable for the revegetation of black beaches and applicable to the treatment of the black beach deteriorated grasslands with different types and grades.

The invention discloses a sieving method of salt tolerant cellar mutant of goat-weed, which is characterized by the following: regenerating callus induced by matured embryo; building sieving system of cellar mutant; obtaining tube vaccine; obtaining the mature goat-weed seed as explant; improving regenerating rate of matured embryo effectively.

The invention relates to a feed for cow, which belongs to the field of livestock feed. The feed provided in the invention comprises: herb residue feed prepared by using herb residue from an extraction of traditional Chinese medicine salviae miltiorrhizae and herb residue from an extraction of pseudo-ginseng as raw materials, corns, leymus chinensis, silage and commercial concentrated feed, wherein herb residue feed is prepared by processing herb residue from an extraction of traditional Chinese medicine salviae miltiorrhizae and herb residue from an extraction of pseudo-ginseng. Herb residue from an extraction of salviae miltiorrhizae can be separately processed or processed after mixing with herb residue from an extraction of pseudo-ginseng, or herb residue from an extraction of salviae miltiorrhizae and herb residue from an extraction of pseudo-ginseng are respectively processed and then mixed according to any weight ratio. The processing method is selected from an alkali treatment method, a microbial fermentation processing method, a puffed processing method or a drying processing method.

The invention discloses a method for restoring degraded grassland ecosystem by establishing Leymus chinensis and belongs to the field of ecological remediation. The method includes digging a round pitin an establishment site, taking 80-90% of excavated soil, adding slow-release urea, diammonium phosphate and decomposed animal waste, mixing well, and backfilling the round pit; covering the round pit with perforated degradable agricultural film, and planting pre-germinated seeds of Leymus chinensis in soil at perforated parts. The method helps prevent the problems that, for instance, shortage of moisture and nutrients causes low germination rate of Leymus chinensis seeds and low survival rate of seedlings; the method is applicable to the grassland ecosystems degraded, desertified and salinized due to various causes, and allows clonal propagation advantages of Leymus chinensis to be fully utilized so as to arrive at restoring a stretch of land by cultivating of a spot.

The invention is a chinensis germination method of combined seed peeling and temperature changing, which belongs to the planting technique field. The invention mainly comprises two parts of: partially or wholly removing the hull of chinensis seed by means of hull peeling so as to break the hard physical structure of the hull and releasing the chinensis seed dormancy aiming to destroy the hard phyical structure of the hull and break the chinensis seed dormancy; as well as rapidly increasing the seed germination rate of chinensis by using the variable temperature technique. The invention concretely has four processes of 1) seed selection and impurity removal, 2) hull-peeling treatment, 3) seed disinfection and 4) variable temperature germination. The invention has the increased seed germination rate from 54.0 percent to over 95.0 percent compared with the seed with hull. Therefore, the invention has significant practical meaning and broad application value to both the chinensis seed cultivation and experimental study.

The invention relates to a method for rapidly constructing artificial grassland of leymus chinensis in saline-alkali degraded meadow, and aims at solving the harm of degeneration saline-alkaline spotsof existing Songnen meadow. The method for constructing the artificial grassland of leymus chinensis comprises the following steps: 1, determining the area of a degraded saline-alkali spot, adoptingsurface-layer saline-alkali spot stripping and carrying out surface-layer backfilling with aeolian sandy soil when the area of the saline-alkali spot is less than 100m<2>, and mixing a modifier into asoil layer for removing alkali for a plurality of times when the area of saline-alkali spot is greater than 100m<2>; 2, repeating a cold water immersion-draining process to break dormancy of seeds, and after air drying treatment, sowing the leymus chinensis seeds into a modified land block; and 3, carrying out routinefield management at a seedling stage of the leymus chinensis, applying a nitrogen fertilizer, and finishing the construction of the artificial grassland of leymus chinensis. Through the method for rapidly constructing artificial grassland in saline-alkali degraded meadow, the artificial grassland can be quickly constructed in the saline-alkali degraded meadow, the cover degree of vegetation is increased, the saline-alkali spot area is reduced, and the land utilization rate and the production function are improved.

The invention discloses a preparation method of a compound microorganism fermentation forage feed. The forage feed is prepared from the following components in parts by weight: 50 to 70 parts of mixed forage, 10 to 20 parts of a biological leavening agent, 5 to 15 parts of a mildew preventive and 8 to 15 parts of a degerming preservative, wherein the mixed forage consists of leymus chinensis, oat grass, legume, corn straws, sorghum stalks, wheat bran, alfalfa and bean cakes. The preparation process is simple, and the preparation process is environmentally friendly and pollution-free; the prepared forage feed is high in nutritional value; if an animal takes the feed for a long time, the immunity can be enhanced, and digestive system diseases can be reduced; meanwhile, the prepared feed can be stored for a long time, and no mildewing and rotting phenomena are caused.
