通过对5种不同方式培育河北杨苗木成效的调查结果表明,不同培育方式对河北杨生长量有显著影响,进而产生不同的经济效益。从经济效益最大化考虑,培育胸径〈2.0 cm杨河北苗木最佳方式是扦插;培育胸径2.0～3.0 cm河北杨苗木最佳方式是第一年扦插,第二年平茬留床培育;培育胸径〉3.0 cm河北杨苗木最佳方式是第一年扦插,第二年平茬留床,第三年间苗,每公顷保留合理密度进行大规格苗木培育。

The results showed that there was a significant effect on poplar' growth with different raising methods, hence brought about different economic benefits. From the consideration of maximization of economic benefit,the best raising method was that: Seedlings of DBH〈2.0 cm were to cutting; Seedlings of DBH from 2.0-3.0 cm were cutting in the first year followed by staying in bed with stubble cuhivation in the second year; Seedlings of DBH〉3.0 cm were cutting in the first year followed by staying in bed then stubble cultivation in the second year and carried out large-size seedlings raising in a reasonable thinning density per ht..
