摘要

加拿大西部地区晚秋气温高于正常水平可能会改变紫花苜蓿(Medicago sativa L.)的标准秋收管理。本研究的目的是评价3种苜蓿品种在不同收获管理下的饲料产量和营养价值。2013 - 2017年,采用根茎型(RR), cv。AC黄头鱼马唐无性系种群。苜蓿(falcata),根型(TR), cv。春分(无性系种群。匍匐根型(CR);紫花苜蓿(亚种)sativa),在Melfort, SK,加拿大。5个收获处理分别为2次1次收割(7月初或7月底)和3次2次收割(7月初+ 9月初或9月底,7月下旬+ 9月下旬)。干生长条件下,RR苜蓿的总饲料产量高于RR苜蓿,但RR苜蓿的总饲料产量高于CR苜蓿。3个苜蓿品种对2次采收管理的反应相似。第一次减产受前一年第二次减产时间的影响,9月初收获的减产幅度大于9月底收获的减产幅度。3个苜蓿品种CP、TDN和ADF浓度相近。两刈制下,全刈制和全刈制苜蓿的养分产量显著高于全刈制苜蓿。尽管草原气候正在变暖,但研究结果表明,无论苜蓿类型如何,都建议在9月下旬之前进行秋季休息,以保持多年的高干草产量。这篇文章受版权保护。版权所有

Effect of fall harvest time on forage yield and nutritive value of three alfalfa cultivars with different root types

Warmer than normal late fall temperatures may change standard fall harvest management of alfalfa (Medicago sativa L.) in western Canada. The objective of this study was to evaluate the forage yield and nutritive value of three types of alfalfa cultivars under different harvest managements. A field experiment was conducted from 2013 to 2017 using rhizomatous type (RR), cv. AC Yellowhead (M. sativa subsp. falcata), tap root type (TR), cv. Equinox (ssp. sativa) and creeping root type (CR), cv. Spredor 4 alfalfa (ssp. sativa), at Melfort, SK, Canada. The five harvest treatments were two 1-cut systems (early July or late July) and three 2-cut systems (early July + early or late September, late July + late September). Total forage yield was greater in TR and CR alfalfa than RR alfalfa; however, RR alfalfa had higher total forage yield under dry growing conditions versus CR alfalfa. The three alfalfa cultivars had a similar response to 2-cut harvest managements. The first cut yield was affected by the timing of the second cut of the previous year with the early September harvest reducing yield more than the late September. Three alfalfa cultivars had similar crude protein (CP), total digestible nutrient (TDN), and acid detergent fiber (ADF) concentrations. There was a significant nutrient yield benefit of TR and CR alfalfa under a 2-cut system over the RR alfalfa. Although the prairie climate is warming, the findings suggest that a fall rest period until late September is recommended regardless of alfalfa types to maintain high hay yield over multiple years.
