| 摘 要： | 灌木状白蜡 (Ｆｒａｘｉｎｕｓｃｈｉｎｅｎｓｉｓ,又称白蜡条 )—农作物间作系统是豫东沙区重要的农林复合经营形式 ,有数百年的经营历史 ,仅宁陵县就有 1 50 0ｈｍ2 。它把多年生的灌木状白蜡和 1年生的作物结合起来 ,不但可以充分利用自然资源 ,生产大量的条子、白蜡杆等小型用材 ,而且还可以改善农田生态系统的结构 ,提高其多样性与稳定性 (王广钦等 ,1 987ａ;1 987ｂ ;1 990 ;ＷａｎｇＧｕａｎｇｑｉｎｅｔａｌ.,1 991 )。因此 ,把条农间作当作一个完整的人工生态系统 ,研究其物质的固定、消耗、分配、循环规律 ,对于进一步研究条农复…

| Abstract: | The biomass,productivity and the material cycle in the shrubby Chinese ash(Fraxinus chinensis)-crop intercropping system (ash+wheat+peanut)were studied in this paper.The results show that:In this system,the biomass was 30.9837～60.4399 t·hm-2·a-1,the annual net productivity was 20.7482～25.1380 t·hm-2·a-1,both of the two were far more than them in the monoculture crop system and artificial forest.The mathematical models were established to estimate the biomass of the shrubby chinese ash.The shrubby Chinese ash-crop intercropping system could improve the nutrient cycling rate.The average cycling rate of six nutrient elements was 20 percent higher than that of monoculture system. |
