小型农村水利改革思路

在分析小型农村水利的特点和性质的基础上,理清了小型农村水利改革的思路。认为：小型农村水利具有工程小、数量多、分布面广,地位重要但易受忽视,涉及范围广、服务功能多、公用性、垄断性、群众性、政策性、公益性、系统性和整体性强,季节使用、经营管理难等特点。改革的核心要按照“谁受益,谁负担,谁投资,谁所有”的原则,组建用水合作组织,明晰所有权。改革的关键是把所有权与经营管理权分开,采用灵活多样的形式加强经营管理。改革的实质是建设与管理制度改革,不能简单理解为“产权制度改革”。     

加快洞庭湖区农机化发展 促进社会主义新农村建设

建设社会主义新农村是我党今后很长一段时期的重大历史任务。新农村建设使洞庭湖区农机化获得了发展良机,而农机化在新农村建设中的地位和作用显著,本文从湖南洞庭湖区新农村建设的要求出发,提出了大力推广水稻生产全程机械化技术,以促进洞庭湖区农村生产发展、农民生活宽裕;坚持依法行政,保障农机安全生产,以促进农村社会和谐,乡风文明;抓好农机部门自身建设,以适应社会主义新农村建设的需求等几项措施。     

Evaluating factors influencing farmers' satisfaction with their irrigation system

The logit technique is used to analyze the relationship between dichotomous reactions of satisfaction (satisfied/dissatisfied) with the irrigation system and certain independent variables. The result shows that five important variables — water availability on time, fertilizer availability, landholding size, farmers' participation in irrigation activities and location of farmland along the canal — significantly determine satisfaction.

A logistic analysis of the factors determining the decision of smallholder farmers to intercrop: A case study involving rubber–tea intercropping in Sri Lanka

The factors influencing the decision of smallholder farmers to adopt new farming technologies were studied with reference to rubber–tea intercropping in Sri Lanka. Rubber–tea intercropping has been recommended previously to rubber farmers as a means to improve productivity and income during the early pre-tapping phase of rubber growth. Although crop trials have shown that the two crops are agronomically compatible and potentially produce a combined economic yield superior to the yield of a sole crop grown on the same area of land, there is little evidence of widespread adoption of this practice among smallholder farmers in Sri Lanka. The aim of the study was to determine the major factors that influence the decision to undertake rubber–tea intercropping and to construct a predictive model that describes the likelihood of adoption of intercropping by traditional smallholder rubber growers. A rapid rural appraisal (RRA) was undertaken based on semi-structured interviews of 90 smallholder farmers in the main rubber growing low wet zone of Sri Lanka. Among a number of factors shown to significantly influence the decision to intercrop tea with rubber, three were shown to operate independently, namely level of income, source of income (i.e. solely from own farm or from farm plus additional off-farm enterprises), and availability of land considered suitable for tea cultivation. A statistical model developed through correlation and logistic analysis, which predicts the likelihood of a smallholder adopting intercropping based on these factors, is presented and discussed. The most likely combination of circumstances (82% probability) under which rubber–tea intercropping is practiced is shown to be where the farmer’s income is greater than Rs. 10,000 per month, where the farmer’s income is based solely on own farm enterprises, and where more than 80% of the farmer’s land area was judged to be suitable for tea cultivation. Conversely, 30% of smallholder farmers that chose not to intercrop did possess land suitable for tea cultivation. Qualitative responses to the RRA indicated that limitation of technical knowledge was the main problem subsequently faced by rubber farmers who had adopted rubber–tea intercropping. Results indicate that there is need for both income support through farm subsidies and further agricultural extension services, if rubber–tea intercropping is to be adopted more widely in Sri Lanka. The wider usefulness of the developed logistic model in determining the likelihood of adoption of intercropping by smallholder farmers is discussed.     

农村人力资源开发的核心--加强农村教育

农村人力资源开发的根本目的是充分发掘和利用农村人力资源,为农村社会经济的发展服务。我国农村人力资源从数量和质量两个方面来衡量,其现状是数量过大、质量供给不足。农村人力资源开发重点在于提高农村人力资源的质量,核心是加强农村教育。即以提高新增劳动力素质为核心,加强农村基础教育;以就业为导向,大力发展农村职业技术教育;以农民培训为重点,大力开展农村成人教育。     

试论农业机械化在社会主义新农村建设中的作用

近几年,随着政策导向和资源配置通过市场杠杆促进农业机械化,使农村拥有的农业机械不断增加,农机化综合水平不断提高,推动了农业耕作制度的革新,加速了农业的产业化步伐和农村劳动力的转移,因此,农业机械化在社会主义新农村建设中发挥着愈来愈重要的作用。
