Abstract

The invention relates to an Italian rye grass and oat mixed sowing method, and belongs to the technical field of ecological agriculture. Different Italian rye grass and oat sowing proportions are set,results indicate that resources are good in complementary property when the sowing rate of Italian rye grasses and oats is 3:5, the competitive advantages of the Italian rye grasses are stable, the feeding value and the production performance of forage grasses are high, the yield of accumulated dry matters reaches 19445.30kg*hm<-2>, the yield of accumulated crude proteins reaches 2814.04kg*hm<-2>, the yield of accumulated digestible dry matters reaches 13135.30kg*hm<-2>, and the method is an optimal oat mixed sowing combination for an Italian rye grass artificial grassland.

Description

technical field [0001] The invention relates to the technical field of ecological agriculture, in particular to a method for mixing ryegrass multiflora and oats. Background technique [0002] Sichuan has abundant winter slack field resources and advantages in water and heat conditions. To meet the needs of agricultural supply-side structural reform, it is proposed to use winter slack fields to develop cool-season annual pasture ryegrass multiflorum (Lolium multiflorum Lam.) and forage corn (Zea mays L. ) high-efficiency forage production system of crop rotation, which is efficiently transformed by herbivorous livestock, has huge production potential and economic benefits. Forage is an important means of production in animal husbandry, and its yield and quality are crucial to the development of animal husbandry. As a high-yield, high-quality, and palatable annual warm-season forage, ryegrass multiflora has continuously expanded its planting area with food and economic crops ...
