化肥过量施用在提高棉花产量的同时也带来了严重的农业环境污染问题,并威胁到棉花产业的可持续发展。文章利用新疆重点植棉区的446农户实地问卷调查所得数据,对农户过量施肥风险认知进行评价,并采用二元logit模型,对植棉农户减少化肥施用量的影响因素进行实证分析。分析结果显示,主要影响因素中的户主年龄、植棉经验、土地质量、土地产权、接受科学施肥技术培训、棉花收入的满意度、棉花收入在总收入中的比例等因素对农户减量施肥有显著影响;农户认为科学施肥是否重要的认知因素和农户家庭人口对农户减量施肥没有显著影响。
Over-fertilization of chemical fertilizers not only raises the output of cotton, but also brings about serious problems of agro-environmental pollution and threatens the sustainable development of the cotton industry. Based on the field survey data of 446 farmer households in key cotton planting areas in Xinjiang, the article evaluates the farmers’ awareness of over-fertilization risk and uses binary logistic model to analyze the influential factors of reduced fertilizer application by cotton-planting farmers. The results of the analysis show that the main factors affecting the household head age, cotton-planting experience, land quality, land property rights, training in scientific fertilization technology, the satisfaction of cotton income, the proportion of cotton income in the total income, Significant impact; Farmers think the scientific fertilization is important whether the cognitive factors and household population of farmers on the reduction of fertilization did not have a significant impact.
