摘要:

本文对太行山低山丘陵区苹果生姜间作系统的生态效应、生理效应、产量效应及土地利用率进行研究,结果表明,对比单作姜园平均可使生姜冠层叶温降低2.5℃,空气相对湿度提高16% ;对比清耕果园,可使0~50cm土层土壤含水量提高8.5% ;可使生姜叶片叶绿素含量提高16.6% ,苹果光合速率提高10.0% ;生姜和苹果单位产量分别提高3.1%和2.0% ;间作系统土地当量值可达1.64,总体土地利用率可提高64%。

关键词: 苹果生姜间作系统, 生态效应, 生理效应, 产量效应, 土地利用率

Abstract:

The effects of the Apple-ginger inter-cropping on ecology, physiology,yields, and the land utilization efficiency in the hilly land of TaiHang Mountain were studied. The results indicated that: (1)the ginger canopy temperatures decreased 2.5℃ and the relative humidity(RH) increased by 16.0% compared with the sole ginger field(CK2); (2) the content of soil water in 0~50cm depth increased by 8.5 % compared with the pure apple tree stand(CK1); (3) the content of Chlorophyll of ginger leaves increased by 16.6 % compared with CK2 ; (4) the photosynthetic rate increased by 10.0% compared with CK1; (5) the yields of ginger and apple increased by 3.1% and 2.0% respectively ,compared with CK2 and CK1; (6) the land equivalent ration(LER) was 1.64, and the land utilization efficiency increased by 64%.
