粗砂壤土
英文
coarse sandy loam-
The elementary idea of the reference units method can be described as follows : firstly, by the setting of double series of reference units, we can control the highest and lowest land quality class of each village or town ; secondly, the class of the arable land will be get through the contrast between the arable land with the reference unit which has been selected in the same area, the difference in quality is the key factor to classify the land. the results show, 87. 6 % of the lands from i to iii distribute on alluvial and lacustrine plains, where the associated soils are mainly grey fulvo - aquic and calcareous concretions black ones. and 61. 4 % of them from iv to vi distribute on slightly rolling parts with mainly yellow - cinnamon soil developed from the diluvial and slope deposits
分等結果表明：臥龍區等的耕地中，有87 . 6分佈在沖積、湖積平原區，主要土壤類型是在河流沖積物上發育形成的灰潮土、在湖相沉積物上發育形成的砂姜黑土；等耕地中，有61 . 4分佈在壟崗區，主要土壤類型是洪坡積物上發育形成的黃褐土：而、等耕地集中分佈在丘陵區，主要土壤類型是殘坡積物上發育形成的粗骨性黃褐土，等別結果分佈總體上體現了不同地貌類型、土壤條件下耕地質量的差異。The organic matter, total n, hydrolytic n were increased, then reduced with the increase of abandoned time. the loss of organic c got up to 59. 4 % in abandoned land. in 0 - 20cm, the sand content of 0. 25 - 0. 05mm was increased gradually, the average content of sand in the abandoned land was up to 76. 84 %, the sand contents of silt and sand was gradually reduced, the soil mechanic compose became coarse
隨撂荒年限的增加，土壤有機質、全氮、堿解氮等主要養分均表現出先降低后增加的趨勢；撂荒地有機碳的損失平均達到59 . 4 ；在撂荒地表面0 - 20cm范圍內， 0 . 25 - 0 . 05mm粒徑的砂粒含量逐漸增加，各撂荒地砂粒平均含量達76 . 84 ，粉粒和粘粒含量逐漸降低，土壤機械組成出現粗化現象。Evaporation varies from evaporation capability, embedded depth of groundwater is more easy, the effect is more obvious ; evaporation capacity decreases if embedded depth of groundwater become deeply, and close to zero under the some depth ; evaporation capacity of different soil texture is different. at ordinary situation, if embedded depth of groundwater is easy, evaporation capacity of the wide and grit soil is powerful ; if embedded depth of groundwater is deep, evaporation capacity of the slender and viscosity soil is powerful
潛水蒸發隨大氣蒸發能力的變化而變化，且潛水埋深越淺，受其影響越明顯：潛水蒸發隨潛水埋深增加而減少，在某一埋深以下潛水蒸發接近於零：不同土質其潛水蒸發量不同，一般情況下，在潛水埋深較小時，土質較粗、偏砂性土壤潛水蒸發較大；當潛水埋深較大時，土質較細、偏粘性土壤的潛水蒸發較大。The research showed that pam could improve soil structure, and greatly increase the stabilization of soil aggregates, so soil crust development would be decreased. fifthly, soil grain that controls rainfall splash erosion was obtained, the influence of soil clay was very great during initial stages of rainfall. with rainfall going on, soil coarse sand and fine sand would control the splash erosion
五、控制土壤濺蝕的主要土壤粒級：在降雨初期土壤的的粘粒對濺蝕速率的影響較大，隨著降雨歷時的延長，土壤中的細砂和粗砂成為濺蝕速率影響較大的因子；六、對土壤濺蝕影響較大的土壤結構特徵因子：降雨5分鐘時，土壤的滲透系數對濺蝕速率的影響較大，隨著降雨的繼續進行，土壤的團聚度一直對土壤濺蝕速率影響較大。All of theses database was integrated into a land information system, which can be used to land evaluation and land use analysis. the second part is the application of soter land information system in land evaluation, based on water balance model watsat, crop simulation model ps 123 and ales ( automated land evaluation system ). the handan land evaluation model was built in ales based on expert knowledge and farmer s " experiences, it includs three decision trees, namely soil erosion risk, soil water condition and soil fertility
以邯鄲地區1 25萬soter土壤土地數據庫為基礎，探討了土壤參數區域化問題，並利用watsat區域水分平衡模型，研究了邯鄲地區區域水分平衡：大部分地區土壤水分滿足夏玉米生長需求， （ suff ）值為0 . 8 - 1 . 0 ，非常適宜；部分地區如大名地區、邯鄲和永年部分地區、涉縣溝谷坡梁地區土壤水分適宜夏玉米生長， suff值0 . 4 ? 0 . 8 ；不適宜地區， suff值0 . 2 ? 0 . 4 ，主要集中於丘陵山區以及平原古河谷地礫石和粗砂分佈區。Impact hammer mills are used in the mining sector and in the pit and quarry industry for primary and secondary crushing of different types of ore and medium - hard rock with a throughput capacity of 1. 500 t h
振動錘碎機在采礦業採石業和土壤業領域里被用來對礦砂和中硬巖石進行粗碎和細碎。它的生產能力可達到1500t h 。The data collected in this study indicates that the paleosol layer is thicker in the southeast region than in the northwest and thicker in the north region than in the south
通過各項指標區域橫向對比發現，砂質古土壤層具有從西北向東南漸變厚變深的規律和粒度值從西北向東南由粗變細的規律。分享友人
