phaeozem 中文意思是什麼
phaeozem
解釋
森林草原土-
Phaeozem is worldwide for fertile and high yield. now it had been changed gully and ditches for large soil erosion
因土質肥沃盛產糧食而聞名世界的黑土，如今正因大量水土流失變得溝壑縱橫。 -
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 )
在吉林玉米帶黑土土壤物理環境方面，兩種不同形狀界面構造土壤在三相組成、有效土壤量、持水性能等方面差異顯著，相關分析表明，吉林玉米帶黑土玉米產量與耕層厚度、有效水含量呈明顯相關關系。 -
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
這兩種界面構造對玉米產量影響差異顯著， 「平面型」界面土壤抗逆性較強，產量最高，平均產量達8 . 23t / hm ~ 2 ，而「波浪型」界面土壤抗逆性較差，它可以分為兩種情況：當耕層厚度15cm時，產量處于中等水平，平均產量為7 . 55t / hm ~ 2 ；當耕層厚度15cm時，產量最低，平均產量為6 . 65t / hm ~ 2 ，此種土壤處于丘陵漫崗區，產量受水土流失影響較大。 -
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
相關分析表明， 「平面型」界面土壤玉米產量與各養分含量間無明顯相關關系，只有當速效磷、鉀含量在五級以下時，產量才受到明顯影響。 -
Ploughing deeper and corn residues might promote formation of soil aggregated structure, decrease soil bulk density, relax solum, decrease soil porosity, raise soil permeability, improve soil structure and holding - water capability, create better soil biology condition for growth of crop, and coordinate water, fertilizer, air and heat etc. to prevent the fertility deterioration of the corn belt phaeozem and ameliorate soil, it is need to reform tillage and fertilizer application for the corn belt phaeozem in the central part of jilin
針對吉林玉米帶黑土土壤退化現象，從黑土玉米的耕作制和施肥制的改革入手，並結合農村現有機械和技術水平，採用玉米「輕主重輔」三三耕作制和玉米「一穩二減三補」施肥技術，提出吉林玉米帶黑土土壤調控技術體系。 -
This paper systemically studied the characteristics of physicochemistry environment of the com belt phaeozem in jilin and analyzed the correlation between corn yields with soil physical and chemical conditions. at the same time, the author studied the soil comprehensive assessement system and regulating and controlling technology in the paper. soil samples came from corn succession cropping phaeozem in the central part of jilin
本文以吉林省中部農區玉米連作黑土為供試土壤，重點研究了吉林玉米帶黑土剖面構造及理化環境特徵，並在此基礎上，對土壤的理化環境指標與玉米產量進行相關分析，初步提出了吉林玉米帶黑土土壤環境與玉米產量關系的檢索指標體系和土壤調控技術。 -
Process of soil loss tolerance research - in the phaeozem region of northeast china
以東北典型黑土區為例 -
Analysis showed that corn yields of the corn belt phaeozem positively related to depth of cultivated horizon and content of available water, respectively, which their correlation coefficient was 0. 788 and 0. 813. at the same time, each of organic carbon, cation exchange capacity and available n was significant positively related to com yields
而「波浪型」界面玉米產量與有機質、陽離子交換量、速效氮呈明顯相關關系。玉米產量隨有機質的增加而呈線性增加，玉米產量與陽離子交換量的相關關系可定量的描述為二項式的形式，相關顯著。
