查询词典 red soil

The DTPA extractable of heavy metal in red soil is significantly higher than that in paddy soil.

土壤中金属的DTPA浸提量与全量呈现显著的正相关。DTPA能浸提出土壤中水溶性、交换态、吸附态、有机固定态和部分氧化态的重金属，这部分相对于其全量被认为是高度生物有效的形态，其快速方便的浸提程序，可以在类似土壤中作为一种有效的重金属污染的评价指标。

For such reasons, the author investigated comprehensively on cropping systems and agriculture development in Fenxin County from 2002 to 2004, using mathematics model and GIS, discussed the cropping systems characteristic and development orientation and optimized the cropping systems spatial distribution. The data were collected from literature, questionnaires to experts and farm households, on-site investigation and field experiments. The main results are as follows:1,Because of inconsequent exploitation and management of the resources, rapid increasing population in hilly region of red soil, the stress on soil, deterioration of farmland ecological environment and soil gleization become more and more serious. Natural features , water and thermal resources and species are abundance.

基于以上目的，作者于2002-2004年，通过资料调研、专家咨询、农户调查、实地考察和田间试验等手段，对江西奉新县的种植制度和农业发展进行了全面的调查，通过建立数学模型和运用地理信息系统，对奉新县的种植制度的特征和发展方向进行了全面的论述，并且对种植制度进行了空间布局优化，主要结果如下： 1、红壤丘陵区由于长期以来对资源的不合理利用和掠夺式经营以及人口的急剧增长，土地压力上升，农田生态环境恶化，土壤潜育化，土壤肥力退化非常严重，但区内自然条件优越、水热资源总量丰富、物种丰富，具有一定的区位优势，为区内种植制度调整提供了有利条件。

The spores of Neocheiropteris palmatopedate were cultured in improved Knop's medium, in-situ humus soil and red soil respectively. Spore germination and gametophyte development were observed under optical microscope and dissecting microscope, and the impact of four culture methods on the gametophyte development and sexual reproduction was compared. On these experiments, its cause of endangerment was analyzed.
