农户对温室滴灌技术满意程度影响因素分析

Factors Affecting Farmers' Satisfaction towards Greenhouse Drip Irrigation Technology

为了探讨限制滴灌技术应用的原因,通过Logistic回归模型分析了影响农户使用温室滴灌技术满意程度的影响因素。结果表明:农户对滴灌技术使用满意程度与受教育程度、技术指导和政府补贴等因素呈显著正相关,与农户年龄、兼业程度和推广技术的限制因素呈负相关。在此基础上,对影响农户使用温室滴灌技术满意程度的关键因素按重要性进行排序:年龄、技术指导、农业投产比、政府补贴、滴灌设备的价格、滴头堵塞、受教育程度、水肥不均、土地细碎化分散程度和兼业程度,其中除兼业程度在显著性水平0.1下和土地细碎化分散程度在显著性水平0.05下较为显著外,其余因素均对农户使用滴灌技术满意程度具有极其显著影响。此外还建立了关键因素与农户使用滴灌技术满意程度的概率关系式。基于实证结果,为温室滴灌技术能够顺利推广提供一定依据。

To find the constraints for drip irrigation technology application, the backward conditional methods of Logistic Regression were used to analyze the factors affecting farmers satisfaction towards greenhouse drip irrigation technology. The results indicated that education, technological guidance, and government subsidies were positively related with it, while farmers age, concurrent de- gree, and the constraints to technology were negatively related with it. Based on the above analysis, key factors for farmerd satisfac tion towards drip irrigation technology were sequenced in order of importance as： age, technological guidance, the input-output ratio for agriculture, government subsidies, price of drip irrigation, emitter clogging, education, nonuniform on fertilizer irrigation, land dispersion degree and farmer＇s concurrent degree. Among these factors, all of these were most critical, except for farmers＂ concurrent degree and land dispersion degree. Also, a probability equation between ten key factors and farmers＂ satisfaction towards drip irriga- tion technology was developed. Based on model-simulated results, the research provided a certain basis for the successful implemen- tation of greenhouse drip irrigation technology.
