水氮耦合对轮伐末期毛白杨纸浆材生长及土壤水养特征的影响
Effect of water and nitrogen coupling on the growth and soil hydrotropic characteristics of populus tomentosa pulpwood at the end of rotation
[目的]水肥耦合被普遍认为是提高林地生产力最有效的措施之一,但目前国内研究多为短期水氮效应研究,缺乏轮伐期末对毛白杨纸浆材水氮耦合的探讨,本文旨在明确轮伐期末毛白杨最佳灌溉施肥策略。[方法]本文以栽植于鲁西北平原的三倍体毛白杨为研究对象,采取大田滴灌水氮耦合试验,研究灌溉施肥后的第四个生长季内(4 月～10 月)各水氮处理的叶面积指数(LAI)、土壤体积含水率(SVWC)的时空动态变化和生长季末林木生长和林地土壤养分规律,从而确定轮伐末期最佳的施…查看全部>>
[Objective]Water-fertilizer coupling is widely considered as one of the most effective measures to improve the productivity of forest land,but at present,most of the domestic researches are short-term water and nitrogen effect researches,and there is a lack of exploration of water and nitrogen coupling of populus tomentosa pulpwood at the end of the rotation period,and this paper aims at clarifying the optimal irrigation and fertilization strategy of populus…查看全部>>
