漫水土層
英文
submerged earth-
Under the filtration irrigation, the water content could remained a fit range from 14 to 22 percent in the layer of 20 to 70 cm deep, however, the general irrigation could reduce the moisture utilization during the growing period of the maize. ( 4 ) filtration irrigation could well adjust the soil temperature so that the root system made a sufficient absorption of the moisture and mineral nutrinents
從土壤含水量測定分析看，在20 70cm土層，滲灌水分含量一直維持在玉米正常所需的14 22范圍內，而漫灌分兩次灌水，在每次灌水前一段時間水分含量要下降到14以下，出現水分脅迫，尤其影響到玉米的前期生長。Because of deposit the ground form, wide soft soil and large thickness, we should use the methods to set up the standard design., such as to change and fill out a stone, lump block of stone of the strong rammer and split off the thick liquid of note and so on
摘要深圳市港灣大道沿線屬前海灣沿岸海漫灘沉積地貌，軟土層分佈范圍廣、厚度大、性狀極差，闡述該路採用的換填塊石、劈裂注漿、插板排水堆載預壓、強夯塊石墩等地基處理方法，進行了標準設計。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。Through example study such as loess tunnel hazard, the modes of surface runoff are generalized as four basic modes : gravity water evenly infiltration mode, surface runoff injection mode, gravity water injection through dominant path mode and multiple mode
以黃土洞穴災害為例，將黃土暗穴形成過程中黃土地層地表徑流的下潛模式概化為滲透重力水漫滲型下潛模式、地表徑流集中灌入下潛型模式、滲透重力水沿優勢滲流通道集中下潛型模式以及混合灌滲集中下潛型模式等4種基本模式。分享友人
