本文利用数理统计原理,采用正交设计方法,探讨培育泡桐优良干材的最佳途径。试验结果证实,在林业科研试验中,正交试验是一种很值得选用的方法,可以弥补林业试验周期长见效慢的弱点,节省人力、物力。
In this paper, the principles of mathematical statistics, the orthogonal design method to explore the best way to cultivate Paulownia dry material. The test results confirm that in the forestry research experiments, the orthogonal experiment is a very worthwhile method, which can make up for the weakness of long-term slowness in the forestry experiment period and save manpower and material resources.
