Seeding technology enabling wheatgrass to be deposited in snow

Abstract

The invention belongs to ecological management methods of glassland and particularly relates to a seeding technology enabling wheatgrass to be deposited in snow. Seeds are sown in winter, low temperature of a snowfield is utilized to limit germinating time of the grass seeds, ice and snow melt is spring next year, water in the soil is adequate, and accordingly the best germinating temperature and humidity are provided for the grass seeds. The seeding technology comprises the following steps: (1) seeding: the wheatgrass seeds are directly sown on the surface of a snow layer after the second now in winter, on the conditions that water is frozen at night and ice melts in the daytime, namely the temperature at night is lower than zero with freezing of the surface of the snow layer as the limit and the temperature in the daytime is higher than zero with melting of the snow layer as the limit; (2) deposition in the snow: through irradiation by the sun, surface layers of the wheatgrass seeds absorb heat, and the wheatgrass seeds can sink to the bottom of the snow layer gradually and slowly by means of self weight and the sunlight when the external temperature is higher than zero so that the snow layer melts; and (3) germination: the soil absorbs plenty of snow water when snow melts in spring next year, and the wheatgrass seeds begin to germinate after the soil is unfrozen.

Description

technical field [0001] The invention belongs to a grassland ecological control method, and in particular relates to a sowing technology of ice grass and snow. Background technique [0002] Wheatgrass ( Agropyron ) plants are native to the steppe region of Eurasia, and there are about 15 species in the world, mainly distributed in Central Europe, the Middle East and Central Asia. Plants of the genus Agropyron are typical xeric grasses, and they are the constitutive species, dominant species or main companion species that constitute the grassland vegetation. They are widely distributed in the vast grasslands of Xinjiang, ranging from plain desert steppes and mountain deserts at an altitude of 600-4000m. Grasslands, mountainous grasslands and even alpine grasslands are distributed. Its ecological distribution range is wide, and its adaptability and stress resistance are strong. It has excellent quality, rich nutrition, and high feeding value. . At present, due to the serious...

AI Technical Summary

Problems solved by technology

Although this method can better guarantee the survival rate of seeds, it is not suitable for use in mountainous and hilly areas in Xinjiang

However, the traditional method used on this terrain is to sow seeds manually, and the seeds are exposed on the surface by grabbing moisture and are easy to be eaten by birds or blown away by spring wind, which seriously affects the emergence rate.

Coupled with the lack of rainfall in arid areas, the remaining grass species cannot germinate smoothly because they cannot absorb enough water
