试验方法同上。在矮壮素的影响下,苹果树的比生产率(指树冠投影的单位面积上的生产率)明显提高。在结果的最初5年,比生产率平均提高了二倍。矮壮素和化肥配合使用,化肥的作用效率增长显著。比如按化肥有效物质单位计算,增产量达二倍以上。化肥和矮壮素配合使用,能使两者相辅相成,提高它们的作用效率。这说明,矮壮素对苹果树生产率的良好影响,在很大程度上可能是在各种营养趋于平衡条件下表现出来的。同时矮壮素对植株的生长和发育过程的影响,又为果树各器官之间可塑性物质的合成和重新分配达得最佳程度创造了先决条件。使用
Test methods Ibid. Under the influence of CCC, the specific productivity of apple trees (the productivity per unit area of canopy projection) is significantly increased. In the first five years of the result, the average productivity has tripled. Chlormequat and fertilizer used in conjunction, the role of fertilizer efficiency increased significantly. For example, according to the unit of fertilizer effective material, increase production more than twice. Fertilizer and the use of chlorin, can make the two complement each other and improve their efficiency. This shows that the good effect of chlormequat on the productivity of apple trees may be manifested to a large extent under the balance of various nutrients. At the same time, the effect of CCC on the growth and development of the plant creates the preconditions for the optimum synthesis and redistribution of the plastic material between the various organs of the tree. use
