甜瓜/向日葵间作系统的土地利用效率和经济效益

Land Use Efficiency and Economic Benefits of Melon/Sunflower Intercropping System

以沙漠绿洲区自然气候条件为基础,以2种作物单作为对照,研究了甜瓜/向日葵间作条件下不同灌溉定额对甜瓜/向日葵间作系统的产量及经济效益等的影响。研究表明,甜瓜/向日葵间作具有显著的间作优势,土地当量比介于1.17-1.89之间。甜瓜/向日葵间作系统的经济效益、经济净效益均高于单作各处理。间作各处理的经济效率显著高于向日葵单作。说明甜瓜/向日葵间作系统具有明显的产量优势,土地利用效率及经济效益得到显著提高。

Based on natural climate condition in the desert oasis,effects of different irrigation quotas on the yield and economic benefit of the intercropping system of muskmelon/sunflower were studied with two kinds of crops monoculture as the control.The results showed that the intercropping system of muskmelon/sunflower had significant intercropping advantages,and land equivalent ration was between 1.17 and 1.89.The economic benefit and the economic net benefits were higher in muskmelon/sunflower intercropping system than those in monoculture treatment.Intercropping benefit per unit water of each treatment was significantly higher than that of sunflower.There were obvious yield advantages for muskmelon/sunflower intercropping system.The land use efficiency as well as the economic benefits were significantly improved.
