    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,本研究基于2009—2020年国家油菜产业技术体系农户固定观察点18个省份17 701个样本的农户调查数据,使用描述性统计方法分析了农户对9个油菜品种性状主观需求的年度变化趋势,研究了不同地区、农地经营规模、地形区域、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。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 trends of subjective demands for different traits of rapeseed varieties and the differences between groups of farmers in China and to provide decisionmaking basis for the breeding of rapeseed varieties,descriptive statistical method was used to report the annual trends of farmers’ subjective demand for traits of 9 rapeseed varieties based on the survey data of 17 701 samples collected from 18 provinces with fixed observation points of China agriculture research system (rapeseed) from 2009 to 2020. Group differences of farmer’s subjective demands for different traits of rapeseed varieties were analyzed between different regions,topographic regions,land scale,age and education level of farmer. The results showed that there were significant differences in farmers’ subjective demand for different traits of rapeseed varieties. According to the annual average of whole nation,the decreasing order was yield (86.15%),followed by 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%). Farmers’ subjective demand for yield decreased by 6.68 percentage,oil extraction rate increased by 28.30 percentage,insect resistance decreased by 17.30 percentage,disease resistance decreased by 1.98 percentage,lodging resistance increased by 15.61 percentage,price of seed decreased by 17.60 percentage from 2009 to 2020. Farmers’ subjective demand for germination rate increased by 33.13 percentage,doublelow increased by 9.29 percentage,suitable for mechanization increased by 2.71 percentage from 2015 to 2020. There were significant differences in farmers’ subjective demand for different traits of rapeseed varieties among different groups of farmers. It is recommended that the breeding of rapeseed cultivars with more resistance should be far more strengthened from the perspective of farmers’ needs and on the basis of further breeding rapeseed cultivars with highyield and high oil extraction rate. Rapeseed cultivars with double-low,high germination rate and suitable for mechanization should be the target of breeding and promotion in the future. A batch of rapeseed varieties with high-quality and high-price can be released to increase the income of rapeseed breeders.
