NOVELTY - Improving Festuca ovina protective enzyme activity under dry conditions, comprises (i) removing all types of solid waste of the compost, drying to a constant weight, selecting compost with grain diameter as 60 meshes, screening the compost, grinding and producing fine waste compost, (ii) uniformly scattering the compost on the surface of soil, and (iii) taking plastic pots, introducing the soil, planting lawn plants in pot, during the early stage of seeding, watering abundantly, two weeks later, watering every one or two days and measuring the index of malondialdehyde and proline.    USE - The method is useful for improving Festuca ovina protective enzyme activity, malondialdehyde and proline under dry conditions, where the texture of the soil is loam (claimed).    ADVANTAGE - The method utilizes the compost, which protects the Festuca ovina from the damage of the free radical of active oxygen and reduces the dry stress to the plant.    DETAILED DESCRIPTION - Improving Festuca ovina protective enzyme activity under dry conditions, comprises (i) removing all types of solid waste of the waste compost, drying at 105 degrees C to a constant weight, selecting compost with a grain diameter as 60 meshes, screening the compost with a grain diameter of 1700 nm, grinding the compost at a speed of 24000 revolution/minute, and producing fine scrap compost with the grain diameters of 1200 nm, 600 nm and 300 nm, (ii) uniformly scattering the fine scrap compost on the surface of the soil, where the ratio of the grain diameter with the part by weight of the soil is 1:60-80 fold, and (iii) taking plastic pots with the diameter of 7 cm and the height of 10 cm, placing soil (150 g) in each pot, where the texture of the soil is loam, planting lawn plants (0.5 g per pot), during the early stage of seeding, controlling the temperature to 20-26 degrees C, and the relative humidity is 40-60%, the light is natural daylight emitting into the house, watering abundantly to make sure that the seed can bourgeon smoothly and the seedling can grow in the early stage, two weeks later, watering every one or two days as 55-65% of the field moisture-holding capacity to maintain within the stress range, and measuring the index of malondialdehyde and proline from the 44th day, where the organic matter content in the compost is 22%, volume is 0.79 g.cm-3, the pH value is 7.62, the extent of porosity is 67.98%, the saturation moisture content is 66.58% and the total content of nitrogen, phosphorus and potassium is 0.34%, 0.34% and 1.21% respectively.
