研究了太行山低山石灰岩区苹果 +小麦复合经营模式的合理经营年限。通过建立树木覆盖率与小麦相对减产率的数学模型、苹果树冠的生长模型 ,建立了农林复合系统合理经营年限的数学模型 ,可以计算出果麦复合系统不同配置模式的合理经营年限。经营年限以该地区乔化砧苹果树最常用的株行距 3m× 4 m为例是 4 a,矮化砧苹果树 2 m× 3m也是 4 a,2 m× 6 m可达 6 a。
This paper studied the reasonable management period of apple + wheat compound management mode in the Taihang Mountain low mountain limestone area. By establishing the mathematical model of tree coverage and the relative yield reduction of wheat and the growth model of apple tree crown, a mathematical model of the reasonable management period of agroforestry system was established, and the reasonable management years of different models of fructus microphylla system could be calculated. The operating life of the apple trees in the area Qiao anvil 3cm × 4m most commonly used as an example is 4 a row, dwarfing an apple tree 2 m × 3m is also 4 a, 2 m × 6 m up to 6 a.
