太行山低山丘陵区果一草复合系统生态经济效应研究

Effects of silvopastoral system on ecology and economics in the hilly land of Taihang Mountain

  • 摘要: 对太行山低山丘陵区苹果一沙打旺复合系统土壤养分、果树生理生态及产量产值、牧草产量及质量、土地当量值研究结果表明,与清耕果园相比,果一草复合系统可使土壤有机质、速效氮分别提高30%、32%,速效钾降低2.1%,而对速效磷影响较小;苹果叶片叶绿素含量提高24.3%,叶片光合速率提高28%,产量提高15.5%。与单作草场相比,牧草产量提高18.5%,粗蛋白质、粗脂肪、可溶性糖含量分别增加36.4%、27.4%和11.8%。复合系统土地当量值(LER)达1.65。

     

    Abstract: The effects of Apple-A .adsurgens system on ecology,physiology and yield,and land equivalent ration in the hilly land of Taihang Mountain are studied.The results show that the contents of organic matter available N in the 0~50cm soil increase by 30% and 32% compared with the pure apple tree stand(CK1)respectively,and the content of available K decreases by 2.1%;the content of chlorophyll and the photosynthetic rate of the apple tree leaves and apple yield increase by 24.3%,28% and 15.5% compared with CK1 respectively;the dried matter yield,the content of coarse protein,the coarse adipose and soluble sugar of A .adsurgens increase by 18.5%,36.4%,27.4%and 11.8% compared with the sole A.adsurgens.system (CKⅡ)respectively,the land equivalent ration(LER)of this system is 1.65.
