在泡桐壮苗培育上怎样以最经济满足泡桐苗木最低实际需肥量,从而达到优质壮苗降低成本的目的,还缺乏研究。将营养诊断的方法用于培育泡桐苗木生产,是使泡桐育苗生产合理化、标准化的重要途径之一。因此,我们开展了泡桐苗木生长规律与植株体内营养元素含最关系的研究和泡桐苗木经济施肥量的研究。现将试验结果总结如下:
Paulownia seedling cultivation in the most economical to meet the minimum practical needs of Paulownia seedlings fertilizer, so as to achieve the purpose of reducing the cost of quality strong seedlings, but also the lack of research. The method of nutrition diagnosis used to cultivate Paulownia seedling production is one of the important ways to rationalize and standardize Paulownia seedling production. Therefore, we carried out the growth of Paulownia seedlings and plant nutrients in the most relevant research and Paulownia seedlings economic fertilizer amount. Now the test results are summarized as follows:
