phaeozem meaning in English
森林草原土
Examples
- Process of soil loss tolerance research - in the phaeozem region of northeast china
以东北典型黑土区为例 - Phaeozem is worldwide for fertile and high yield . now it had been changed gully and ditches for large soil erosion
因土质肥沃盛产粮食而闻名世界的黑土，如今正因大量水土流失变得沟壑纵横。 - There was obvious dependence relationship between corn yields with changing of depth of cultivated horizon and available water content , corn yields of the corn belt phaeozem changed regularly
相关分析表明， “平面型”界面土壤玉米产量与各养分含量间无明显相关关系，只有当速效磷、钾含量在五级以下时，产量才受到明显影响。 - Corn yields of phaeozem in " flat type " " boundary soil ( depth < 15cm ) reached 6 . 65t / hm2 . in addition to , content of available , water , organic carbon . cation exchange capacity and available n was the most in " flat type " boundary soil ( depth = 30cm )
在吉林玉米带黑土土壤物理环境方面，两种不同形状界面构造土壤在三相组成、有效土壤量、持水性能等方面差异显著，相关分析表明，吉林玉米带黑土玉米产量与耕层厚度、有效水含量呈明显相关关系。 - The results show that the physical and chemical conditions of the corn belt phaeozem have significant different in different profile morphological characteristics . in another way , soil composition of three phases , content of available water , nutrient content and composition of humus have significant different in different profile morphological characteristics . among three groups of profile morphological characteristics , corn yields of phaeozem in " flat type " boundary soil ( depth = 30cm ) were the most , reached 8 . 22t / hm2on average . corn yields of phaeozem in " wave type " boundary soil ( depth = 15cm ) reached 7 . 55t / hm2 on average
这两种界面构造对玉米产量影响差异显著， “平面型”界面土壤抗逆性较强，产量最高，平均产量达8 . 23t / hm ~ 2 ，而“波浪型”界面土壤抗逆性较差，它可以分为两种情况：当耕层厚度15cm时，产量处于中等水平，平均产量为7 . 55t / hm ~ 2 ；当耕层厚度15cm时，产量最低，平均产量为6 . 65t / hm ~ 2 ，此种土壤处于丘陵漫岗区，产量受水土流失影响较大。
