Dongmu 70 rye
The more annual grasses are cold-resistant, drought-resistant, and moisture-resistant, with lax soil requirements, producing 4500-6500 kg of fresh grass per 667 square meters (1 mu) and 12-15% crude protein content in dry matter. It is an excellent winter forage. Its nutrition is rich, palatability is good, direct feeding livestock and poultry, the utilization rate is high. It is determined that milk yield can be increased by 13-19% when Dongmu 70 rye is fed to dairy cows. Linfen Linken Agricultural Development Company mainly uses silage corn in the cold mountain area at an altitude of 1000-1200 meters. It produces 5000-7500 kg of grass per 667m2 of rye twice a year with winter grazing. Combined with seasonal grazing, 667m2 of grass is fed to 5-7 sheep.
