【摘要】：本文主要研究不同覆蓋方式對(duì)油松生態(tài)公益林成活率、生長(zhǎng)效果及生長(zhǎng)環(huán)境的影響,研究表明,不同覆蓋方式下,滲水地膜的整體綜合效果最為理想,礫石覆蓋效果次之,這兩種覆蓋方式對(duì)營(yíng)建油松生態(tài)公益林的積極效果顯著高于其他三種覆蓋方式。滲水地膜的優(yōu)勢(shì)主要體現(xiàn)在：一、滲水地膜有利于油松生態(tài)公益林內(nèi)微氣候的形成,但不影響土壤與外界因子之間的物質(zhì)交換和能量循環(huán)。二、滲水地膜可以緩沖環(huán)境變化對(duì)油松根系的刺激作用,對(duì)油松根系生長(zhǎng)有十分積極的作用。 試驗(yàn)證明,油松生態(tài)公益林在營(yíng)建過(guò)程中,最適宜的覆蓋方式應(yīng)為滲水地膜覆蓋法,但由于滲水地膜覆蓋法造價(jià)較高,在實(shí)際營(yíng)建過(guò)程中,可綜合考慮區(qū)域經(jīng)濟(jì)水平,選擇造價(jià)較低的礫石覆蓋法。
[Abstract]:In this paper, the effects of different mulching methods on survival rate, growth effect and growth environment of Pinus tabulaeformis ecological public welfare forest were studied. The positive effects of these two kinds of mulching methods on the construction of ecological public welfare forest of Pinus tabulaeformis were significantly higher than those of the other three. The advantages of water seepage film were mainly reflected in the following aspects: first, the infiltration film was conducive to the formation of microclimate in the ecological public welfare forest of Pinus tabulaeformis. But it does not affect the material exchange and energy cycle between soil and external factors. Secondly, the permeable film can buffer the stimulative effect of environmental changes on the root system of Pinus tabulaeformis, and play a very positive role in the root growth of Pinus tabulaeformis. The test results show that the most suitable way to cover the ecological public welfare forest of Pinus tabulaeformis should be the method of water seepage and film mulching, but because of the high cost of the method, the level of regional economy can be considered comprehensively in the process of construction. The method of gravel covering with lower cost is chosen.
