棕壤性粗骨土果园雨季前覆膜草把营养穴中土壤条件明显改善,苹果根系生长兴旺,根量明显增多。根系分布有所改变,根系吸水吸肥能力及土壤中水肥利用率显著提高。与此相应,蒸腾作用,光合生产能力亦明显提高,形成一个良性循环。实测及热力学理论分析均证明;这项措施能在不更多投入肥水条件下实现壮树,如结合诸如修剪等其它措施可获丰产。
Brown soil coarse bone orchard before the rainy season mulched grass nutrition conditions significantly improved soil conditions, apple root growth and prosperity, root volume increased significantly. Root distribution has changed, root absorption capacity of water absorption and soil water and fertilizer utilization rate increased significantly. Correspondingly, transpiration, photosynthetic production capacity has also significantly improved, forming a virtuous circle. Both measured and thermodynamic theoretical analyzes have demonstrated that this measure can achieve strong trees without more fertilizer and water inputs, and can be productive if combined with other measures such as pruning.
