First, autumn sowing avoids the spring drought problem encountered in spring sowing. Autumn rainfall is relatively concentrated, making the soil moisture content in autumn relatively high, and due to the gradual fall in autumn temperatures, shortened sunshine hours, reducing the evaporation of soil moisture. Therefore, soil moisture is good in autumn, and sowing can make the soil have relatively sufficient moisture to ensure seed germination.
Second, the autumn sowing can avoid weed coverage and affect the growth problems encountered in spring sowing. Pasture seeds are generally small, especially some legumes such as alfalfa, clover, and ryegrass grasses, fescue, and other grass perennial grass, seedling growth is slow, when spring sowing, the growth rate of pasture is not as fast as the return of green weeds, often appear The phenomenon of weeds covered by weeds, sowing grass in the autumn, most of the weeds gradually withered, and generally did not have an adverse effect on the growth of forage seedlings.
Third, the autumn sowing is conducive to the spring of the next year, the germination and growth of pasture. The pasture planted in the autumn has a strong root system after the end of autumn and winter. In the spring of the following year, the returning green time is earlier than that of the weed, and it grows faster than the weeds, which can inhibit the growth of weeds.
Fourth, autumn pasture can prevent wind erosion of soil in winter and spring. Many winter and waste lands and stubble lands lack vegetation cover throughout the winter and spring seasons. When arid and high temperature conditions are encountered, surface soils in winter and winter are subject to wind erosion, causing loss of nutrients in the soil and affecting the soil. Fertility. After autumn pasture in these winter resorts, the wind erosion of the soil can be greatly reduced due to the fixing and covering of pasture.
