摘要
Inverary的4250公顷土地中,约有一半是海拔750米以上的未开发山地。这里有300公顷的河滩,种植苜蓿和冬季饲料作物,还有300公顷的传统草地/苜蓿。三叶草/车前草和冬饲料作物的有限面积已在一个起伏较大的国家海拔约700米处建立。1600公顷的陡峭乡村以棕地为主,春季和盛夏产量较低,难以管理。2009年,没有苜蓿或富含豆类的牧场。强调豆类通过提高产羔率和出售佩雷韦的羔羊体重来提高动物生产力。羊肉总产量从2009年的230113公斤上升到2020年的245039公斤,尽管减少了1000公斤。目前绵羊与牛的比例为60:40,有13000只牲畜正在过冬。在发育前,早春营养饲料的严重短缺,加上夏秋难以控制繁殖草,加剧了这一问题。2016年,以豆类为主的牧场的总产量比施用有限氮肥的湿草/三叶草牧场高40%(15吨/公顷/年,11吨/公顷)。早春,豆科植物的生长速度高于传统草/苜蓿(90与44 kg DM/ha/天),而棕顶优势山地牧场的生长速度分别为10 kg DM/h/d和5 tDM/公顷/年。
Legumes are the key to increasing productivity at “Inverary”, a summer moist hill / high country farm in mid-Canterbury
About half the 4250 ha of Inverary is undevelopedmountain land above 750 m a.s.l. There are 300 haof river flats, where lucerne and winter feed cropsare grown, and 300 ha conventional grass/cloverpastures. Limited areas of clover/plantain and winterfeed crops have been established at ~700 m a.s.l. oneasy rolling country. The 1600 ha of steep country,dominated by browntop, gives low spring and highsummer production that is difficult to manage. In2009, there were no lucerne or legume rich pastures.The legume emphasis increased animal productivitythrough improved lambing and lamb weight sold perewe. Total lamb meat production lifted from 230,113kg in 2009 to 245,039 kg in 2020, despite 1000 fewerewes. The current sheep to cattle ratio is 60:40 with13,000 stock units being wintered. Pre-development,a major shortage of nutritious forage in early springwas compounded by difficulty controlling reproductivegrass in summer and autumn. In 2016, total productionof legume dominant pastures was 40% more than sowngrass/clover pastures with limited nitrogen fertiliser(15 vs. 11 t DM/ha/year). In early spring, legumeshad higher growth rates of conventional grass/cloverpastures (90 vs. 44 kg DM/ha/day), whereas browntopdominant hill pastures grew 10 kg DM/ha/d and 5 tDM/ha/yr.
