多年生作物试验的设计与分析,其基本原理相似于通常一年生作物的田间试验,但多年生作物的生育规律有其特殊性,因而设计与分析的具体方法也有所不同。多年生作物如茶、油桐、果树等的田间试验的特点有三:(1)每一试验小区上的供试材料较少,因而试验植株的质和量必需极为一致;(2)在多年的试验期间,供试的植株不变,所受的处理不变,占地亦同,因而试验前最好作一空白试验,明了区间或株间的原有差異,用以纠正试验后的产量,提高试验正 The design and analysis of perennial crop experiments are similar in principle to field trials of annual crops. However, perennial crops have their own particularities in their reproductive laws. Therefore, the specific methods for designing and analyzing perennial crops are different. There are three characteristics of field trials of perennial crops such as tea, tung tree, and fruit trees: (1) there is less material to be tested on each test plot and thus the quality and quantity of the test plants must be extremely consistent; (2) During the test plant unchanged, subject to the same treatment, covering the same, so the best before the test as a blank test, clear the original interval or between the differences in order to correct the test after the yield and increase Test positive
