Effects of Long-Term Organic Amendments on Soil Organic Carbon in a Paddy Field: A Case Study on Red Soil

引用

Journal of Integrative Agriculture 2014年第3期13卷 570-576页

作者： HUANG Qing-hai LI Da-ming liu kai-lou YU Xi-chu YE Hui-cai HU Hui-wen XU Xiao-lin WANG Sai-lian ZHOU Li-jun DUAN Ying-hua ZHANG Wen-ju National Engineering and Technology Research Center for Red Soil Improvement Jiangxi Institute of Red Soil Key Laboratory of Crop Nutrition and Fertilization Ministry of Agricultural/Institute of Agricultural Resources and Regional Planning Chinese Academy of Agricultural Sciences

Soil organic carbon （SOC） is one of the main carbon reservoirs in the terrestrial ecosystem. It is important to study SOC dynamics and effects of organic carbon amendments in paddy fields because of their vest expansion in south China. A study was carried out to evaluate the relationship between the SOC content and organic carbon input under various organic amendments at a long-term fertilization experiment that was established on a red soil under a double rice cropping system in 1981. The treatments included non-fertilization （CK）, nitrogen-phosphorus-potassium fertilization in early rice only （NPK）, green manure （Astragalus sinicus L.） in early rice only （OM1）, high rate of green manure in early rice only （OM2）, combined green manure in early rice and farmyard manure in late rice （OM3）, combined green manure in early rice, farmyard manure in late rice and rice straw mulching in winter （OM4）, combined green manure in early rice and rice straw mulching in winter （OMS）. Our data showed that the SOC content was the highest under OM3 and OM4, followed by OM1, OM2 and OM5, then NPK fertilization, and the lowest under non-fertilization. However, our analyses in SOC stock indicated a significant difference between OM3 （33.9 t ha^-1） and OM4 （31.8 t ha^-1）, but no difference between NPK fertilization （27 t ha^-1） and nonfertilization （28.1 t ha^-1）. There was a significant linear increase in SOC over time for all treatments, and the slop of linear equation was greater in organic manure treatments （0.276-0.344 g kg-1 yr^-1） than in chemical fertilizer （0.216 g kg^-1 yr^-1） and no fertilizer （0.127 g kg^-1 yr^-1）.

为建立轻型化的再生稻高产技术体系,并在赣东北种植和推广再生稻,于2009—2010年在江西省余江县开展了再生稻轻简栽培和播期试验,分析了源库关系、生物量和氮积累量以及产量等指标。结果表明,与人工栽插相比,直播和抛秧在头季稻后期和再生稻的叶面积指数显著较低,降幅为5.1%～57.8%,在头季稻中其实粒数分别比人工栽插减少了25.3%～41.2%,再生稻中分别降低了9.9%～46.5%,再生稻中生物量分别比人工栽插减少了23.7%～53.2%,氮积累量分别降低了20.0%～54.4%。这表明直播和抛秧等轻简栽培方式的源小库弱,从而导致其再生稻产量比人工栽插降低了30.1%～35.1%。不同播期之间是较早播种的再生稻占用的温光资源较多,3月下旬和4月上旬播种的处理在头季稻和再生稻的源库关系、生物量和氮积累量以及产量均显著高于较晚播种的处理,因此通过提前播种可以优化直播和抛秧的源库关系,提高再生稻的产量。

土壤水溶性盐和酶活性是土壤健康的重要指标,可以反映保护地土壤盐渍化趋势与生物学特性。对洛阳近郊李楼乡不同种植年限及不同层次的蔬菜保护地土壤水溶性盐与酶活性进行了研究,结果表明,小麦玉米轮作地和不同种植年限的保护地中土壤水溶性盐总量都在土壤表层积累;保护地土壤的水溶性总盐量在种植年限1～5 a时显著增加,随着种植年限的增加逐渐降低,但仍显著高于小麦玉米轮作地。保护地土壤中过氧化氢酶活性随着土层深度增加而增加,脲酶和蔗糖酶活性有随土层深度增加而减弱的趋势。保护地在一定年限(1～5 a和5～10 a)的蔬菜种植下,其土壤水溶性总盐量与土壤酶活性之间相关性不显著,但随着种植年限的增加,土壤总盐量与脲酶和蔗糖酶活性呈显著正相关。

High-resolution imaging through randomly dynamic scattered fields and highly scattered walls is an extensively sought-after capability with potential applications in various fields such as underwater imaging, biomedical imaging, and seeing through fog. Numerous methods have been proposed to unscramble object information from degraded scattered images, resulting in considerable improvements in image contrast in degraded scenarios [1].
