禾本科与豆科饲草作物间套作对饲草品质及氮素吸收影响的研究进展
Research Advances on the Effects of Cereal/Legume Forage Intercropping on Forage Quality and Nitrogen Uptake
摘要
Abstract
The primary issue preventing the forage sector from growing further at the moment is the scarcity of high-quality fodder.Studies on the production of fodder cropping systems with high yield,high quality,and high nutrient usage efficiency have proliferated in recent years.When compared to solitary crops,it has been demonstrated that intercropping cereals and legumes improves fodder productivity,quality,and nutrient utilization efficiency.The benefits of forage intercropping,however,differed depending on the species mix.Therefore,we classified the cereal/legume forage intercropping systems into two types.One is the short forage intercropping,which is mainly about wheat forage crops,the other is tall/short forage intercropping,which is mainly about silage maize intercropping.The results showed that the short forage intercropping increased the yield,quality and nitrogen uptake of wheat grass forage,and increased the yield and quality of most legume forage;the yield and quality of tall/short forage intercropping were increased in one crop and decreased in the other crop.At the same time,the interspecific interaction mechanism of forage intercropping to improve yield,quality and nitrogen uptake and utilization was summarized in terms of the aboveground and belowground ecological niche compensation of intercropping.It is proposed to strengthen the research on forage interspecific intercropping mechanism and to achieve synergistic increase in yield and quality of cereal and legume forage by screening intercropping varieties and optimizing the arrangement of strips according to local conditions.We aimed to clarify the suitable species combinations and advantages for the forages intercropping with high yield,high quality,and high nutrient efficiency.关键词
