摘要
本试验通过选取耐寒品种“康赛”苜蓿在呼伦贝尔地区进行4个不同的行距处理下种植,并对苜蓿的产量、农艺性状、营养品质进行测定分析,探索不同行距对呼伦贝尔地区紫花苜蓿产量及营养品质得影响。试验结果显示,种植行距显著影响干草产量,干草产量随着行距的增加呈现先增加后降低的趋势,在行距为35 cm时苜蓿的干草产量达到最高(6408.30 kg/hm^(2))。种植行距显著影响苜蓿的粗蛋白质含量,在行距为25 cm时苜蓿的粗蛋白质含量达到最高(20.34%)。其他性状指标表现无差异,我们采取TOPSIS法对数据进行分析,得出行距在35 cm时Ci取得最大值。综合干草产量、生物性状和营养品质指标,本试验研究的紫花苜蓿“康赛”品种在呼伦贝尔地区最佳种植行距为35 cm。
In this experiment,the cold-tolerant variety"Kangsai"alfalfa was planted in 4 different row spacing treatments in Hulunbuir area,and the yield,agronomic characteristics,and nutritional quality of alfalfa were determined and analyzed to explore the effect of different row spacing on the yield and nutrition of alfalfa in Hulunbuir area.Quality has to be affected.The results of the experiment showed that the planting row spacing significantly affected the hay yield.With the increase of the row spacing,the hay yield first increased and then decreased.When the row spacing was 35 cm,the hay yield of alfalfa reached the highest(6408.30 kg/hm^(2)).Planting row spacing significantly affects the crude protein content of alfalfa.The crude protein content of alfalfa reaches the highest(20.34%)when the row spacing is 25 cm.There was no difference in the performance of other traits.We used the TOPSIS method to analyze the data and found that Ci reached the maximum value when the line spacing was 35 cm.Comprehensive hay yield,biological characteristics and nutritional quality indicators,the optimal planting row spacing of the alfalfa"Kangsai"variety studied in this experiment is 35 cm in Hulunbuir.
