水肥处理对仁用杏新品种木瓜杏生长的影响

Effect of water and fertilizer treatments to the growth indexes of 'mugua' almond-apricot

以仁用杏品种中1年生木瓜杏树为试验材料,采用盆栽控水控肥试验的方式,研究水分、肥料以及二者之间的共同作用对木瓜杏苗木生长指标的影响。试验得出以下结果:木瓜杏具有较高的抗旱性;木瓜杏树的生长指标随水分及肥力水平的提高而逐渐升高,适量的施肥可以在干旱胁迫下有效地促进木瓜杏的生长;另外,适当的施肥可以缓解干旱胁迫对木瓜杏植株的影响,提高植株的抗旱能力。

Experiment was conducted with the 1-year-old ＇mugua＇ almond-apricot.Pot experiments were carried out to study the effect of water and fertilizer treatments and the interaction to the growth indexes of ＇mugua＇ almond-apricot.The results were as follows： It was indicated from the research that the of ＇mugua＇ almond-apricot possess strong drought resistance.The results indicate that all increased with the increase of water and fertilization levels.And application of fertilizers with limited amounts could effectively promote growth of ＇mugua＇ under drought stress.And the result showed that the effect of drought stress on the plant could be alleviated effectively with rational application of fertilizer.The drought-resistant ability of the plant also could raise with the fertilizer treatments.
