辽西坡地林农复合经营模式优化研究

Optimization of Agroforestry Model on Slope of Western Liaoning

在辽西坡地上,通过枣农、梨农、桃农、杏农等林农复合经营模式试验筛选及产量、产值分析,结果表明,该区适宜的林农复合优化模式为枣农复合模式;通过榛子、核桃干果树种+作物复合经营与枣农复合对比试验,结果表明枣农复合经营为辽西坡地林农复合首选模式;继续试验研究了枣农复合优秀组分为铃铛枣与谷子,是辽西坡地同一土地单元内高效的林农复合模式。

On slope of western Liaoning province,through test screening,production value analysis on jujube ＋ millet ＋ soybean,pear ＋ millet ＋ soybean,peach ＋ millet ＋ soybean,apricot ＋ millet ＋ soybean other models,result shows that：jujube ＋ millet ＋ soybean is suitable for this area;through compared experiments of dried fruit trees of hazelnuts or walnut ＋ crop and jujube ＋ millet ＋ soybean,result shows that jujube ＋ millet ＋ soybean is the preferred model for western Liaoning;Lingdang jujube ＋ millet,which is optimal component for jujube ＋ millet ＋ soybean,is high-efficient agroforestry in the same land-unit on slope of western Liaoning.
