红壤

Based on the systems analysis of the ecosystem in intervale region of south China, the feedback structure model of the ecosystem was established by rate variable fundamental in? tree modeling of System Dynamics.

在对红壤丘陵区生态系统进行系统分析的基础上，利用系统动力学的流率基本入树建模法，建立了红壤丘陵区生态系统的反馈结构模型。

Effects of long-term fertilization on labile organic matter and carbon management index in reddish paddy soil were studied in order to assess soil quality.

以长期定位试验点的红壤性水稻土为研究对象，研究了长期不同施肥制度对红壤性水稻土活性有机质和碳库管理指数的影响。

Compared carbon pools and turnovertime under different soil types, the result shows: soil total organic carbon is grey cinnamonforest soil＞dark-brown soil＞meadow soil＞brown coniferous forest soil＞red soil＞yellowsoil＞yellow brown soil＞paddy soil＞red soil＞flubo-aquic soil＞fengsha soil,temperate forest soil＞subtropical forest soil＞subtropical cropland soil＞temperate dry soil.Active carbon is temperate forest soil＞subtropical soil.

对不同土壤类型的碳库及其驻留时间进行比较，得出：有机碳含量呈现：灰褐土＞暗棕壤＞草甸土＞棕色针叶林土＞红壤＞黄壤＞黄棕壤＞水稻土＞农田红壤＞潮土＞风沙土，温带森林土壤＞亚热带森林土壤＞亚热带农田土壤＞温带干旱土壤；活性碳含量是温带森林土壤＞亚热带的土壤。

The study indicated that Choerospondias axillaries cropped with peanut wasn't optimum agroforestry model and it couldn't be extended blindly in subtropical China, that N〓-fixing shrub should be chosen to intercropped in farmland rather than tree, and that shade tolerance plant should be chosen to intercropped in orchard garden or man-made forest rather than photophilous plant in alley cropping system.

总之，花生南酸枣间作不是低丘红壤地区优化农林间作模式，不适宜盲目发展。在红壤农田系统中实行农林间作应优先选择固氮灌木，而非高大的乔木；在果园或人工林系统中实行农林间作应优先选择耐荫植物，而非花生等喜光作物。

The polymeric soil amendmentswere applied in increasing soil value,and reclamation of saliane sodic soil,and greeningdesert,and controlling water and soil erosion,and amending arid and semiarid soil,andincreasing fertilizer utilization rate and crop yield,etc.

本文研究了淀粉接枝共聚物、羧甲基纤维素接枝共聚物、壳聚糖接枝共聚物、聚丙烯酰胺及其衍生物等对赤红壤的改良作用，揭示了赤红壤在这些聚合物作用下理化参数的变化规律。

The water leakages in red soil farmland in northeast of Jiangxi province were studied using large scale weighing lysimeter, time domain reflectometry and tensiometer.

红壤区是我国水土流失严重地区之一，该区降水量大且分布集中，一般认为红壤的入渗透水性能差是引起土壤侵蚀的一个重要原因。

In paddy soils,a better response to magnesium fertilizer was found in milk vetch than in the suc- ceedi...

难溶性镁肥在酸性红壤上的效果很好，但在接近中性的红壤旱地上，最好施用速效性镁肥以保证作物苗期的镁素供应。

Climate and soil factor of Catanopsis hystrix native forest in fifteen countries were surveyed, results showed that Distribution area of Castanopsis hystrix native forest in Gangxi belongs to south subtropical seasonal wind climate, and Castanopsis hystrix native forest in the forest mainly was representative types of south subtropical seasonal rain forest and ever - green broad - leaved forest in China.

通过调查统计广西15个红锥天然林县市的气候和土壤因子，结果表明广西红锥天然林分布的地区属南亚热带季风气候区，以红锥天然林为主的森林是我国南亚热带季雨林化常绿阔叶林的代表类型；红锥天然林分布以赤红壤、红壤林地出现较多，土壤酸碱度为微酸性（pH4.36～6.23）。

This research studies the effects of mineral oil of Lateritic Red Earth and Laterite on the paddy's and peanut's physico-ecologies and the reduction of mineral oil in these soils by the pot-planting simulation test.

本研究采用盆栽试验法，研究了赤红壤、砖红壤中矿物油对水稻、花生的生理生态影响和矿物油在土壤中的净化。

The P release contents in the runoff sediments of the lateritic red soil of granite, lateritic red soil of sand shale and limestone soil reached the maximum in 9,7and 12 days, respectively. The phosphorus concentration on 4, 1 and 5 days exceeded river acceptable DRP critical value, respectively; therefore, it had obvious influences to water eutrophication.

花岗岩赤红壤、砂页岩赤红壤和石灰岩土径流沉积物中磷释放量达到最高所需时间分别为9天、7天和12天，磷浓度分别在第4天、第1天和第5天超过河流可接受的可溶态活性磷的临界值，因此土壤径流沉积物中磷的释放对水体富营养化具有明显的影响。

他将怎样告诉朱迪丝和孩子们呢？

I this is at that time, the opinion with peacockish true girl is full of in a heart.

这就是当时的我，一个心中布满虚荣的女孩子真实的想法。
