Cultivation method of interplanting of two high-quality forage grasses and Zizyphus mauritiana Lam

Abstract

The invention discloses a cultivation method of interplanting of two high-quality forage grasses and Zizyphus mauritiana Lam. The method comprises the steps of variety selection, selection and leveling of a planting area, planting of the Zizyphus mauritiana Lam and seeding of the forage grasses, field management and harvest and utilization of the high-quality forage grasses. The two high-quality forage grasses are annual super-high Lolium multiflorum L. and perennial Medicago sativa L.WL525HQ. The two high-quality forage grasses are subjected to row planting between the rows of the Zizyphus mauritiana Lam at the same time, the total output of dry grass is increased by 618.71 kg / mu more than the output of the interplanting of single Lolium multiflorum L. and the Zizyphus mauritiana Lam, and increased by 60.47 kg / mu more than the output of the interplanting of single Medicago sativa L. and the Zizyphus mauritiana Lam, and the average increased output values are 1546.78 Yuan / mu and 151.18 Yuan / mu respectively. Meanwhile, the labor cost for weeding is averagely reduced by 460 Yuan / mu. The method is beneficial to construction of large-area orchard grass-planted farming production bases in the Jinsha River dry-hot valley and other areas, and the new and efficient technical method is provided for the development of fruit and animal product industries in the Jinsha River dry-hot valley and other areas.

Description

technical field

[0001] The invention relates to a cultivation method for interplanting high-quality forage grass and jujube trees, belonging to the technical field of agricultural and forestry production. Background technique

[0002] Annual ryegrass (Lolium multiflorum L.) likes warm and humid climates, and grows fastest when the temperature is 12-27°C. It grows faster than other grasses in autumn and spring, and is most suitable for growing in areas with precipitation of 500-1500mm. It is suitable for autumn planting in the dry and hot valley of the Jinsha River. It has poor drought and cold resistance, and grows well in moist, well-drained fertile soil and irrigation conditions, but it is not tolerant to severe cold and dry heat. Whereas areas with higher elevations and cooler summers can grow for two years with proper management. Annual ryegrass has a long growth period, rapid growth, early mowing time, and strong regeneration ability. Generally, it is mowed 4 to 6 tim...
