【摘要】：長(zhǎng)期不合理開發(fā)導(dǎo)致東北黑土肥力下降,伴隨嚴(yán)重土壤物理性質(zhì)惡化,但針對(duì)物理性質(zhì)重要性及造林恢復(fù)可能性研究較少。因此本研究以東北地區(qū)土壤為研究對(duì)象,測(cè)定不同物理性質(zhì)(土壤孔隙度、比重、容重、比表面積、土壤含水量、土壤最大吸濕水)及其它理化和肥力指標(biāo)(土壤電導(dǎo)率(EC)、pH值、土壤有機(jī)碳(SOC)、全氮(TN)、堿解氮(AN)、全鉀(TK)、速效鉀(AK)、全磷(TP)、速效磷(AP)、球囊霉素相關(guān)土壤蛋白(TG和EEG))的基礎(chǔ)上,分別從其相關(guān)關(guān)系及受造林與否(農(nóng)田和楊樹防護(hù)林)和造林樹種(針葉林和闊葉林)的影響進(jìn)行研究,得出以下結(jié)論：(1)物理性質(zhì)與其余指標(biāo)相關(guān)關(guān)系方面：土壤比表面積、容重和孔隙度3個(gè)孔隙指標(biāo)與其它指標(biāo)顯著相關(guān)個(gè)數(shù)及相關(guān)系數(shù)R2顯示,土壤容重與土壤肥力及理化性質(zhì)變化相關(guān)性最高。不同物理指標(biāo)對(duì)于表征土壤肥力的功能存在差異性：土壤的比表面積與土壤含水量的相關(guān)性最強(qiáng)(R2=0.24, slope=0.085),表明土壤比表面積越大,土壤持水能力越強(qiáng)：土壤容重與土壤SOC含量相關(guān)程度最強(qiáng)(R2=0.21, slope=-24.92),而土壤的孔隙度與TN含量的相關(guān)程度最高(R2=0.08,slope=0.02)。3個(gè)指標(biāo)與養(yǎng)分的不同形式的相關(guān)性分析結(jié)果顯示：它們多與全量養(yǎng)分(TN、TK.TP)相關(guān)性較高(R2=0.058),而與養(yǎng)分速效量(AN.AK和AP)相關(guān)性較弱(R2=0.026)。(2)受造林與否影響方面：30余年的楊樹造林在lm土壤剖面能夠顯著增加土壤孔隙度(1.89%)、顯著降低土壤容重(60mg/cm3)和含水量(0.93%),伴有增加土壤K和降低P的趨勢(shì),但土壤N, TG, EEG和SOC沒有明顯的變化。土壤孔隙相關(guān)指標(biāo)的提升與球囊霉素和SOC在土壤物理結(jié)構(gòu)調(diào)節(jié)效能方面的提升是相關(guān)連的,并且楊樹林的線性斜率,R2值分別是農(nóng)田的1.2-2.8倍和1.6-2.4倍。養(yǎng)分的變化在不同地點(diǎn)和土層之間是存在顯著交互作用的。同各地點(diǎn)農(nóng)田相比楊樹防護(hù)林消耗更多的水,并且土壤比表面積與土壤含水量密切相關(guān)。我們的研究結(jié)果對(duì)于從土壤改進(jìn)的角度對(duì)農(nóng)田造林實(shí)踐的評(píng)估和管理提供支撐。(3)受造林樹種影響方面：較針葉林而言,闊葉林在0-60cm土層內(nèi)顯著增加土壤含水量21.4%,孔隙度95%,SOC 2.2g/kg, AN 9.5mg/kg, TN 0.1g/kg, AP 1.4mg/kg, TP 0.05g/kg,顯著降低了土壤容重2.7%。此外,通過針、闊葉林間土壤理化性質(zhì)與土壤肥力相關(guān)指標(biāo)的關(guān)系的差異分析得知,葉片類型的差異能夠顯著影響土壤含水量與SOC及土壤pH與土壤磷(TP、AP)的相關(guān)關(guān)系,其中土壤含水量的變化對(duì)針葉林SOC影響更大,而土壤pH的變化對(duì)闊葉林磷的影響更大。并且土壤理化指標(biāo)的變化對(duì)土壤TN的影響更為顯著,尤其土壤容重的變化(R2=0.68)。我們的研究將為中國東北地區(qū)的土壤退化及其評(píng)估提供一定的數(shù)據(jù)支撐。
[Abstract]:Long-term unreasonable exploitation led to the decline of soil fertility in Northeast China, which was accompanied by the deterioration of soil physical properties. But there are few studies on the importance of physical properties and the possibility of afforestation restoration. Therefore, this study takes the soil of Northeast China as the research object, and measures different physical properties (soil porosity, specific gravity, bulk density, specific surface area). Soil water content, maximum moisture absorption) and other physical, chemical and fertility indexes (soil electrical conductivity, soil organic carbon (SOC), total nitrogen (TNN), alkali-hydrolyzed nitrogen (ANN)). Total potassium (TK), available potassium (AK), total phosphorus (TP), available phosphorus (APP), balloon mycin related soil proteins (TG and EEGG). The effects of afforestation (farmland and poplar shelterbelt) and afforestation species (coniferous forest and broad-leaved forest) were studied. The following conclusions are drawn: (1) physical properties are related to the other indexes: soil specific surface area, bulk density and porosity are significantly related to the other indexes, and the correlation coefficient R2 shows. Soil bulk density had the highest correlation with soil fertility and physical and chemical properties. There were differences in the function of soil fertility with different physical indexes. The correlation between soil specific surface area and soil water content was the strongest (P < 0.05). R2P 0.24. Slope0. 085, indicating that the larger the specific surface area of soil, the stronger the water holding capacity of soil. The correlation between soil bulk density and soil SOC content is the strongest (R2 + 0. 21). The correlation between soil porosity and TN content is the highest (R20.08). The results of correlation analysis of three indexes and nutrient were as follows: most of them had high correlation with total nutrient (TNT K. TPV) (R2N 0.058). However, the correlation with available nutrient amount (AN.AK and APP) is weaker than that with R2C0.026, AK and AP2). The poplar afforestation for more than 30 years under the influence of afforestation or not can significantly increase the soil porosity in the soil profile (Lm). Decreased soil bulk density (60mg / cm ~ (3)) and water content (0.93%), accompanied by increasing soil K and decreasing P, but soil N, TG. There was no significant change in EEG and SOC. The improvement of soil porosity related indexes was related to the improvement of soil physical structure regulation efficiency by balloon mycin and SOC and the linear slope of poplar forest. R2 values were 1.2-2.8 times and 1.6-2.4 times of farmland, respectively. There was significant interaction between different sites and soil layers in nutrient changes. Compared with the farmland in different locations, poplar shelterbelts consumed more. Water. And the soil specific surface area is closely related to the soil moisture content. Our results provide support for the evaluation and management of afforestation practices in farmland from the perspective of soil improvement. Affected by afforestation tree species: more than coniferous forest. Broad-leaved forest significantly increased soil water content in 0-60cm soil layer by 21.4m, porosity 95 / kg SOC 2.2 g / kg, an 9.5 mg / kg. TN 0.1 g / kg AP 1.4 mg / kg TP 0.05 g / kg significantly decreased soil bulk weight 2.7%. The analysis of the relationship between soil physical and chemical properties and soil fertility among broad-leaved forest showed that the difference of leaf type could significantly affect soil water content and SOC, soil pH and soil phosphorus. Among them, the change of soil water content has more influence on SOC of coniferous forest. The change of soil pH had more influence on phosphorus in broad-leaved forest, and the change of soil physical and chemical index had more significant effect on soil TN. In particular, the variation of soil bulk density is 0.68. Our study will provide some data support for soil degradation and assessment in Northeast China.
