Dihaploid homozygous Fescue species may be produced by interspecific hybridization of Fescue with novel ryegrass, Lolium multiflorus, lines, that induce genome loss. Plants that are dihaploid homozygous Lolium and amphidiploids are also produced.

The invention discloses a method for improving heat resistance of cool-season tall fescue turfgrass by externally applying spermidine, and relates to the technical field of management for landscaping turfs. The method comprises the following steps: 1, planting a tall fescue turf; 2, determining the optimal concentration of spermidine, wherein a 0.5mmol / L spermidine solution is used, so that the injury effect of high temperature to the tall fescue turf can be obviously improved, and the quality of the turf and the photosynthetic capacity are improved; 3, externally applying the spermidine solution, wherein the 0.5mmol / L spermidine solution is sprayed on leaf surfaces of the tall fescue turf when the high temperature is equal to or higher than 35 DEG C at the high-temperature initial stage of summer, the spraying amount is 85kg / mu, and spraying is supplemented for one time after one week if the high temperature lasts. According to the method disclosed by the invention, spermidine is externally applied, so that the injury of the high temperature to tall fescue is obviously reduced, and the quality of the turf is improved; the method has shorter period and faster effect than breeding for a heat resistant variety; spraying on the leaf surfaces is realized, and the operability is strong; the cost is low.

The invention relates to a plant matching mode suitable for vegetation recovery of a permafrost region project slash. The plant matching mode comprises the following steps: (1) mixing roegneria thoroldiana, snowfox crested wheatgrass, leymus and poa crymophila keng at the weight ratio of 2 to 2 to 2 to 3, so as to obtain a mixture applicable to an project slash of an alpine grassland region which takes ecological recovery as an aim; (2) mixing the roegneria thoroldiana, elymus nutans, puccinellia tenuiflora and puccinellia distans parl at the weight ratio of 3 to 1 to 2 to 2, so as to obtain a mixture applicable to the project slash of the alpine grassland region which takes the ecological recovery as the aim; and (3) mixing the elymus nutans, poa pratensis cv.Qinghai, the poa crymophila keng and festuca sinensis at the weight ratio of 3 to 2 to 2 to 1, so as to obtain a mixture applicable to a project slash of an alpine meadow which takes the ecological recovery as the aim. The plant matching mode provided by the invention is suitable for the plant matching mode of recovered series of a permafrost region, has extensionality and can be applied to plant recovery and reconstruction of project slashes with different types.

The invention discloses a method for regulating growth of festuca arundinacea in a hot summer environment by a sludge mixed seed soaking solution, which comprises the following steps: the sludge / rare-earth mixed seed soaking solution is composed of a sludge leaching solution and a rare-earth solution in a weight ratio of 1:1, wherein the sludge leaching solution is prepared by mixing sludge and distilled water in a weight ratio of 1:2, standing for 24 hours and filtering; and the rare-earth solution is a water solution containing 200-400 mg.L<-1> Ce(NO3)3.6H2O or La(NO3)3.6H2O. The experimental result indicates that the sludge mixed seed soaking solution can induce the accumulation of the seedling in-vivo proline, and can maintain the proline on a high level in the strong light and heat activation process, thereby enhancing the growth property of the festuca arundinacea in the field under high-temperature conditions in summer.

The invention discloses a method for controlling the growth of compost substrate festuca arundinacea by using modified nano carbon. The method comprises the steps of: sealing the lower end of each PVC pipe of which the diameter is 3cm and the height is 25cm with a layer of cotton cloth and a nylon net, mixing garbage compost and all modified nano carbons uniformly in proportion, and charging 150g of mixed material into each pipe; passivating for 7 days, sowing 0.2g of festuca arundinacea seeds in each pipe, controlling the temperature to be 19-27 DEG C and the relative humidity to be 60-72% during experiment, supplementing water to the compost every day so that the moisture of the compost reaches 70% of field capacity, balancing for 30 days in a laboratory, and measuring; wherein the adding amount of each modified nano carbon is 1-5%(w / w) of the weight of the garbage compost. Experimental results show that the growth of the compost substrate festuca arundinacea is promoted by adding the modified nano carbon.

The invention relates to application of a mixed turf matrix in improving content of festuca arundinacea pigment. Results show that corn straws and fined life refuse are compounded to be beneficial to the growth of the festuca arundinacea, and all indexes are remarkable and higher than those of a contrast group, wherein the ratios of 28+2, 27+3 and 26+4 are relatively better. Therefore, on the whole, a given mass of corn straws is added into thoroughly decomposed life refuse, which can promote the growth of the lawn plants (festuca arundinacea) and can ensure that the turf matrix and the root system of the lawn plants have better bonding effect.

The invention relates to a method for fast identifying the meadow type high fescue heat-proof quality in the field of cool quaternary type meadow resistance identifying biology technology. It puts the best seed of the meadow type high fescue species in the basin with the sand, clay and nutritious soil (the volume ratio is 1:3:3), and breeds it for 18 days at normal temperature, wherein part plant moves to the artificial climate case with the temperature of 35+ / -0.5 deg. in daytime and the temperature of 30+ / -0.5 deg. in dark time with the optical photon 150-200 mumolm<-2> s<-1> and the percentage humidity 65-70% for three days. It adds non-nutrients during the breeding course. It separately collects the meadow type high fescue health leaf at normal temperature and the high temperature and measures the chlorophyll a and b content of unit weight of the leaf tissue.

The invention relates to a domestication method for enhancing the salt resistance of festuca arundinacea. The domestication method comprises the following domestication processes that: a domestic garbage compost substrate is flatly spread on a sample plot, then the compost becomes compact and flat by press, and the average thickness of the compost substrate is 20cm; the sowing mode is spring sowing, water in the compost substrate, which is used for domesticating the festuca arundinacea in each year, only depends on natural precipitation, and the seeds of the festuca arundinacea are harvested after 4 domestication years; a lawn nursery strip mode is as follows: the carrier of the lawn nursery strip of the festuca arundinacea is designed into double layers, i.e. a lower layer is newspaper and an upper layer is face tissues, and the seeds of the domesticated festuca arundinacea are bonded between an upper carrier and a lower carrier by an adhesive; the sowing quantity is 0.02g / cm2; afterthe seeds germinate, the seeds are transplanted onto a saline soil substrate with the salt content of 0.5 to 1 percent, the temperature is controlled at 20 to 26 DEG C, the relative humidity is 30 to50 percent, and the normal growth of plants is guaranteed; and after the plants of the festuca arundinacea are cultured for 35d, lawn plants and the substrate are mown, and the salt resistance of thedomesticated festuca arundinacea is measured after treatment.
