【摘要】 为了充分利用宾川干热河谷区丰富的光、热、水、土资源,提高柑橘园建园初期(1～3年)的综合效益和复种指数,促进果农增收,采用"乔(灌)+农经作物"的建园方法,建立柑橘园套种模式,提出典型模式建设关键技术,并进行效益分析。结果表明:柑橘园前3年幼树期进行作物套种,能以短养长,使柑橘园每年平均增收32 340元/hm2,套种经济作物每年最高增收达55 200元/hm2;能改善柑橘园小气候,培肥土壤;改善土壤物理性状;抑制杂草,减少虫害,保持果园生态系统平衡,保护人类健康;提高柑橘园的资源利用率,节本增效,社会效益得到充分体现。更多还原

【Abstract】 In order to made the best of abundant photo-thermal resources,water and soil resources in Binchuan Dry Hot Valley,and improved comprehensive benefits and multiple cropping index in 1 to 3 years of orangery development preliminary stage,promoted orchardist increase income,the study adopted the orangery intercropping ways of "arbor(shrub) + agricultural and industrial crop",set up orangery intercropping models,put forward key technology of representative models,carried out benefit analysis.The results showed that the peasants got annual average income 32 340 CNY / hm2 by intercropping in the front 3 years,and the income from intercropping supplied management funds for the orangery.The most annual income was 55 200 CNY / hm2 if the intercropping crop was cash crop.The intercropping ameliorated the microclimate and soil physical behavior of the orangery,and increased the soil nutrient.The intercropping could control rank grass,and reduce insect pest,and keep the balance of orangery ecosystem,and protect the human health.The orangery intercropping not only improved resource utilization rate of the orangery,but also saved costing,and embodied social benefits fully.更多还原
