摘要:

为优化刺槐人工林施肥方案、提高集约经营的肥料利用效率,采用控制试验方法合理配比林木肥料。以1~3年生刺槐人工幼龄林为研究对象,采用三因子(氮磷钾)二次正交回归试验设计方法,对位于河南民权林场的窄冠刺槐幼龄速生丰产林进行连续3年的施肥试验。结果表明,施肥显著促进刺槐的胸径增长,2年增长幅度分别达186.67%、47.30%,3年生幼龄刺槐林最佳施肥处理平均胸径可达7.6 cm。二次回归检验表明,经过连续3年施肥,拟合方程的平方项和总回归项已达到显著水平,失拟检验逐渐失效,拟合方程向着有意义的方向发展。尝试模型转换后进行数据处理不成功,刺槐林地施肥的正交试验无法转变为其他模型处理。通过三因子二次正交回归试验拟合刺槐施肥回归方程有效,以此寻求刺槐人工林最优施肥方案方法可行。

Abstract:

Control test was used to optimize fertilizing scheme and to improve fertilizer utilization efficiency in the management of black locust plantation forest. Through three-factor quadratic orthogonal regression test, fertilizer was applied to the juvenile narrow-crown black locust fast-growing and high-yield plantation forest for three consecutive years in Minquan forest farm of Henan Province. The results showed that fertilization could significantly promote diameter growth, and increasing range of the two consecutive years could reach 186.67% and 47.30% respectively, the diameter growth of 3 years could reach 7.6 cm. Regression test showed that after three years, quadratic model and total model reached significant levels, and lack of fit test was being invalid, and fitting equation was becoming significant. Converting mode to treat data was failed, which proved the attempt completely impossible. Conclusion is drawn that it is effective to fit regression equation by three factors quadratic orthogonal regression test, and it is possible to find the optimal fertilization scheme of black locust plantations forest.

Key words: black locust plantation forest, fertilizer allocated proportion, quadratic orthogonal regression, fitting equation, scheme optimization
