‘公农’黄花草木樨品种选育鉴定评价

Evaluation of variety selection and identification of Melilotus officinalis. ‘gongnong’

为了解决野生黄花草木樨产草量低的问题,同时满足吉林省畜牧业发展对优质高产抗逆牧草的需求,试验对选育的‘公农’黄花草木樨新品种进行品种比较试验、区域试验、生产试验及营养品质测定。结果表明:‘公农’黄花草木樨新品种2011—2012年的平均鲜草、干草产量达到52 791 kg/hm^(2)和10 979 kg/hm^(2),分别比对照增产21.71%和14.32%,且差异达到显著水平(P<0.05);平均种子产量为480 kg/hm^(2),比对照增产20.00%。2015—2017年5个试验点连续两个生长周期的区域试验过程中,‘公农’黄花草木樨表现出了很好的丰产性、适应性和稳定性。2015—2016年3个试验点的‘公农’黄花草木樨的平均鲜草、干草产量达到43 296 kg/hm^(2)和9 093 kg/hm^(2),分别比对照增产18.55%和11.37%。‘公农’黄花草木樨是优质的蛋白饲料。说明该品种具有较强的适应性,耐寒、耐旱、耐轻度盐碱,产草量高,营养品质好,可作为吉林省天然草地改良、人工草地建设、饲草饲料资源开发利用的优良草种之一。

In order to solve the problem that low grass yield of wild Melilotus officinalis, and to satisfy the demand of high quality and high yield forage for animal husbandry development in Jilin Province, in this experiment, the variety comparison test, regional test, production test and nutritional quality determination of the selected new variety of Melilotus officinalis. ‘Gongnong’ were carried out. The results showed that the average fresh grass and hay yield of new cultivar Melilotus officinalis. ‘Gongnong’ reached 52 791 kg/hm^(2) and 10 979 kg/hm^(2) in 2011—2012, which were increased by 21.71% and 14.32% compared with the control, respectively, and the difference reached a significant level(P<0.05). The average seed yield was 480 kg/hm^(2), which was 20.00% higher than the control. In the regional test process of five test sites for two consecutive growth cycles from 2015 to 2017, Melilotus officinalis. ‘Gongnong’ showed high productivity, adaptability and stability. The average fresh grass and hay yield of Melilotus officinalis. ‘Gongnong’ in three experimental sites reached 43 296 kg/hm^(2) and 9 093 kg/hm^(2) in 2015—2016, which were 18.55% and 11.37% higher than the control, respectively. Melilotus officinalis. ‘Gongnong’ is high quality protein feed. The results showed that the variety has strong adaptability, such as cold tolerance, drought tolerance, mild saline-alkali resistance, high yield of grass, good nutritional quality. It could be used as one of the excellent grass species for improving natural grassland, constructing artificial grassland and exploiting forage resources in Jilin Province.
