    摘要:

    为了解农户对油菜品种不同性状主观需求的群体间差异与未来变化趋势,为油菜品种选育提供决策依据,论文基于2009-2020年国家油菜产业技术体系农户固定观察点18个省份17701个样本的农户调查数据,使用描述性统计方法报告了农户对9个油菜品种性状主观需求的年度变化趋势,分析了不同地区、地形区域、农地经营规模、年龄和受教育程度农户对油菜品种不同性状主观需求的群体间差异。结果显示:1、农户对不同油菜品种性状的主观需求程度存在显著差异,按全国年均情况排序,依次为:产量(86.15%)、抗病性(68.02%)、出油率(62.28%)、抗倒性(61.43%)、发芽率(43.47%)、抗虫性(41.41%)、是否适合机械化(35.63%)、是否“双低”(35.60%)、种子价格(30.98%)。2、2009-2020年农户对产量的主观需求下降了6.68%,出油率上升了28.30%,抗虫性下降了17.30%,抗病性下降了1.98%,抗倒性上升了15.61%,种子价格下降了17.60%;2015-2020年农户对发芽率的主观需求上升了33.13%,是否“双低”上升了9.29%,是否适合机械化上升了2.71%。3、不同农户群体间对油菜品种性状的主观需求存在明显差异。论文建议,从农户需求角度出发,未来在进一步选育高产和高出油率油菜品种的基础上,继续加强具有抗性性状的油菜品种选育,有针对性地进行双低品种、高发芽率品种和适合机械化品种的选育和推广,可以推出一批优质高价油菜品种,增加油菜育种人员科研收益。

    Abstract:

    To better understand the future variation trend and group difference on farmers’ subjective demand of rapeseed variety characters, and to provide suggestions for cultivation of rapeseed cultivars, survey data of 17701 samples from 18 provinces with fixed observation points of China agriculture research system (rapeseed) from 2009 to 2020 was collected. Descriptive statistical method was used to report the variation trend of farmer’s subjective demand of rapeseed nine variety characters over the past years. Group difference was analyzed between different regions, topographic regions, land scale, age and education level. The results showed that: 1. There were significant differences in farmers’ subjective demand for different rapeseed variety characters, according to the annual average of whole nation, in order from large to small is: yield(86.15%), disease resistance(68.02%), oil extraction rate(62.28%), lodging resistance(61.43%), germination rate(43.47%), insect resistance(41.41%), suitable for mechanization(35.63%), double-low(35.60%), price of seed(30.98%). 2. From 2009 to 2020, farmers' subjective demand for yield decreased by 6.68 percentage points, oil extraction rate increased by 28.30 percentage points, insect resistance decreased by 17.30 percentage points, disease resistance decreased by 1.98 percentage points, lodging resistance increased by 15.61 percentage points, price of seed decreased by 17.60 percentage points. From 2015 to 2020, farmers' subjective demand for germination rate increased by 33.13 percentage points, double-low increased by 9.29 percentage points, suitable for mechanization increased by 2.71 percentage points. 3. There were significant differences in the subjective demands of rapeseed variety characters among different farmer groups. It was suggested that in the future, high-yielding and high oil extraction rate rape cultivars should be better cultivated, the cultivate of rapeseed cultivars with more resistance should continue strengthened, rapeseed cultivate and promote with double-low, high germination rate and suitable for mechanization character should be more targeted. In order to increase the benefits of rapeseed cultivars workers, a number of high quality and high price rape varieties can be launched.
