豆科、禾本科两种牧草异行混播草地当年建植效果的研究
Study on the Planting Effect of the Mixed Grassland with Two Kinds of Leguminous and Gramineous Forages under the Different Sowing Patterns
摘要
Abstract
[Objective] The technical way of planting high quality and high yield, stability and long -term use of mixed artificial grassland were researched based on the different seeding rates and different sowing ways in the area with rainfall of above 500 mm. [ Method] The experiment design set the mixture patterns that were Dactylis glomerata + Onobrychis viciaefolia and Bromus inermis + Onobrychis viciaefolia at the mixed sowing ratio of 5: 5,4: 6 and 6:4 three kinds of treatments and the treatment with 1:1,2: 2 and 3: 3 lines of different planting; when flowering and heading, the density, height and forage yield of community various group were studied and the economic characters were contrasted. [Result]The results showed that; various economic indexes are better than other planting patterns and at 1 line, the forage yield of mixed 6 :4 were higher than other mixed ones and the average yield could reach 1 276.8 g/m2 in Dactylis glomerata + Onobrychis vidaefolia and the forage yield of the ratios 6: 4 and 5: 5 were higher than other mixed sowing rate at I' 1 line, the average yield of which could reach 1 194.95 and 1 242. 3 g/m2 in Bromus inermis + Onobrychis viciaefolia. [ Conclusion ] Good growth vigor and high performance were showed, among which, the increases of legumes yield can greatly enhance the quality of grassland in planting year at the research site.关键词
