紫花苜蓿与冰草混播当年对牧草品质的影响
Effects of mixed sowing of Medicago sativa and Agropyron cristatum on forage quality
摘要
Abstract
[Objective]To screen the optimal mixed seeding ratio of Medicago sativa and Agropyron cris-tatum in the hope of providing a theoretical basis for the establishment of high quality artificial grassland in northern Xinjiang.[Methods]The effects of mixed sowing of legume and grass on forage quality were analyzed by means of forage nutrient index detection technique and mathematical statistics method.The ratios of legume-grass mixtures of the seven treatments were A(3∶7),B(4∶6),C(5∶5),D(6∶4),E(7∶3),M.sativa and A.cristatum.[Results]There were significant differences in forage nutrition quality and proportion of mixed sowing in mixed sowing year,and the crude fat content of mixed sowing treatment was significantly in-creased compared with that of single sowing of alfalfa(P＜0.05).Under C(5∶5)treatment,the contents of neutral and acid detergent fibers were lower(38.64％and 27.51％,respectively),crude protein content was 19.01％,total carbon,total nitrogen content and soluble sugar content were higher(40.21％,3.04％and 41.77％,respectively).The results of the comprehensive evaluation of grey correlation degree for different treatments were BC＞C(5∶5)＞A(3∶7)＞D(6∶4)＞E(7∶3)＞B(4∶6)＞MX.[Conclusion]M.sativa and A.cristatum can improve the nutritional quality of herbage,and the nutritional quality of mixed sowing herbage is better than that of MX,and the best mixed sowing ratio of 5∶5 is used in the mixed sowing treatments.关键词
