【摘要】：荔枝产业成熟期短,各产区鲜果上市期持续一个半月左右,导致中国荔枝产业供给结构矛盾突出,阶段性的供过于求与供不应求并存,加之品种结构不合理,加剧荔枝供给结构问题,严重制约荔枝产业竞争力的提升,调节品种结构与均衡产期分布成为当务之急。推广高接换种技术是解决荔枝产业品种结构问题的最佳途径。相比于引种、选种与杂交育种等品种调控技术,高接换种技术具有节约资源、技术成本低等优点,适合大范围推广应用。因此,实证研究高接换种技术经济效益与荔枝种植户采用高接换种技术影响因素具有重要的现实意义。本研究以诱导性技术创新理论与农户行为理论为基础,基于相关研究成果,采用典型案例分析法、问卷调查法、统计分析法、计量检验法对荔枝高接换种技术经济效益与技术采用影响因素进行实证研究,研究发现:(1)追踪调查广东茂名市信宜县级市徐启志果园与阳江市阳西县华翔果场采用高接换种技术的经济效益,在正常生产年景和其他因素不变的条件下,两个果园的平均单产、销售收入、销售价格均明显提高,产值成本率下降,成本利润率增长,整体生产经营效率上升。(2)不同地区荔枝种植户以及同一地区高接换种技术采用户与未采用户之间户主特征、稀缺要素、市场需求、信息获取差异均达到显著水平,说明荔枝种植户自身特征、稀缺要素、市场需求及信息获取、地区差异对高接换种技术采用行为产生影响,其中荔枝生产年限、土地成本、销售价格、技术实施成本对荔枝种植户采用高接换种技术行为产生显著正向影响。针对高接换种技术推广过程中存在的问题,提出对策建议,包括建立完善荔枝市场价格信息平台、推进新品种引进与推广工作、设立技术采用补贴机制、积极开展技术培训、合理调整产区品种结构、科学规划产区熟期分布。
[Abstract]:The short maturity period of litchi industry and the period of fresh fruit market in various producing areas lasted for about one and a half months, which led to the prominent contradiction of supply structure of Chinese litchi industry, the coexistence of oversupply and shortage of supply, and the unreasonable variety structure. It is urgent to increase the supply structure of litchi, seriously restrict the competitiveness of litchi industry, and adjust the variety structure and balanced distribution of litchi production period. It is the best way to solve the variety structure problem of litchi industry by popularizing high-grafting technique. Compared with variety control techniques such as seed selection and hybrid breeding, high seed replacement technology has the advantages of saving resources and low technology cost, so it is suitable for wide application. Therefore, it is of great practical significance to study the economic benefits of high grafting technology and the influencing factors of litchi growers to adopt high grafting technology. Based on the theory of inductive technological innovation and the theory of farmers' behavior, this study adopts typical case analysis, questionnaire survey and statistical analysis, based on the relevant research results. An empirical study was carried out on the economic benefit and the factors affecting the adoption of the technique of high-grafting litchi seed replacement by metrological test method. The study found that the economic benefits of using high seed replacement technology in Xuqizhi orchard of Xinyi County, Maoming City, Guangdong Province, and Huaxiang Fruit Farm in Yangjiang City, Yangjiang City, under the conditions of normal production year and other factors unchanged, The average unit yield, sales income, and sales price of the two orchards were significantly increased, the cost ratio of output value decreased, and the cost profit rate increased. The overall production and management efficiency of litchi growers in different areas and the same area of high seed replacement technology between the household and non-mining users of the household characteristics, scarce elements, market demand, information acquisition differences reached a significant level. The characteristics of litchi growers, scarcity factors, market demand and access to information, regional differences have an impact on the adoption of high seed replacement technology, including litchi production years, land cost, sales price, etc. The cost of technology implementation had a significant positive effect on the behavior of litchi growers adopting high grafting technique. In view of the problems existing in the process of popularization of high seed replacement technology, the countermeasures and suggestions are put forward, including establishing and perfecting the price information platform of litchi market, promoting the introduction and popularization of new varieties, setting up a subsidy mechanism for technology adoption, and actively developing technical training. Reasonable adjustment of the variety structure of production areas, scientific planning of maturity distribution in production areas.
