【摘要】：荔枝產(chǎn)業(yè)成熟期短,各產(chǎn)區(qū)鮮果上市期持續(xù)一個(gè)半月左右,導(dǎo)致中國(guó)荔枝產(chǎn)業(yè)供給結(jié)構(gòu)矛盾突出,階段性的供過(guò)于求與供不應(yīng)求并存,加之品種結(jié)構(gòu)不合理,加劇荔枝供給結(jié)構(gòu)問(wèn)題,嚴(yán)重制約荔枝產(chǎn)業(yè)競(jìng)爭(zhēng)力的提升,調(diào)節(jié)品種結(jié)構(gòu)與均衡產(chǎn)期分布成為當(dāng)務(wù)之急。推廣高接換種技術(shù)是解決荔枝產(chǎn)業(yè)品種結(jié)構(gòu)問(wèn)題的最佳途徑。相比于引種、選種與雜交育種等品種調(diào)控技術(shù),高接換種技術(shù)具有節(jié)約資源、技術(shù)成本低等優(yōu)點(diǎn),適合大范圍推廣應(yīng)用。因此,實(shí)證研究高接換種技術(shù)經(jīng)濟(jì)效益與荔枝種植戶采用高接換種技術(shù)影響因素具有重要的現(xiàn)實(shí)意義。本研究以誘導(dǎo)性技術(shù)創(chuàng)新理論與農(nóng)戶行為理論為基礎(chǔ),基于相關(guān)研究成果,采用典型案例分析法、問(wèn)卷調(diào)查法、統(tǒng)計(jì)分析法、計(jì)量檢驗(yàn)法對(duì)荔枝高接換種技術(shù)經(jīng)濟(jì)效益與技術(shù)采用影響因素進(jìn)行實(shí)證研究,研究發(fā)現(xiàn):(1)追蹤調(diào)查廣東茂名市信宜縣級(jí)市徐啟志果園與陽(yáng)江市陽(yáng)西縣華翔果場(chǎng)采用高接換種技術(shù)的經(jīng)濟(jì)效益,在正常生產(chǎn)年景和其他因素不變的條件下,兩個(gè)果園的平均單產(chǎn)、銷(xiāo)售收入、銷(xiāo)售價(jià)格均明顯提高,產(chǎn)值成本率下降,成本利潤(rùn)率增長(zhǎng),整體生產(chǎn)經(jīng)營(yíng)效率上升。(2)不同地區(qū)荔枝種植戶以及同一地區(qū)高接換種技術(shù)采用戶與未采用戶之間戶主特征、稀缺要素、市場(chǎng)需求、信息獲取差異均達(dá)到顯著水平,說(shuō)明荔枝種植戶自身特征、稀缺要素、市場(chǎng)需求及信息獲取、地區(qū)差異對(duì)高接換種技術(shù)采用行為產(chǎn)生影響,其中荔枝生產(chǎn)年限、土地成本、銷(xiāo)售價(jià)格、技術(shù)實(shí)施成本對(duì)荔枝種植戶采用高接換種技術(shù)行為產(chǎn)生顯著正向影響。針對(duì)高接換種技術(shù)推廣過(guò)程中存在的問(wèn)題,提出對(duì)策建議,包括建立完善荔枝市場(chǎng)價(jià)格信息平臺(tái)、推進(jìn)新品種引進(jìn)與推廣工作、設(shè)立技術(shù)采用補(bǔ)貼機(jī)制、積極開(kāi)展技術(shù)培訓(xùn)、合理調(diào)整產(chǎn)區(qū)品種結(jié)構(gòu)、科學(xué)規(guī)劃產(chǎn)區(qū)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.
