The lower limits of soil moisture for rational deficit irrigation scheduling to cotton at its different growth stages are 55 60 , 65 , 70 and 50 55 of field capacity at seedling , buds , bolls and wadding stages , respectively 合理的棉花調虧灌溉制度是苗期控制水分供應，土壤含水量維持在田間持水量的55 60 ；蕾期和花鈴期是棉花的需水關鍵期，土壤含水量應分別保持在田間持水量的65和70左右；吐絮期應控制水分供應，土壤含水量維持在田間持水量的50 55 。
Moreover , according to different land use types , bulk density shows the lowest value for the woodland while the highest value for the grassland and the subsoil of farmland , saturated soil moisture and field capacity exhibit the highest values for woodland while the lowest for the grassland and the subsoil of farmland , and the wilting moisture in woodland is also the highest and that in the farmland is the lowest 不同土地利用類型土壤物理性質也存在顯著差異，容重以農地亞表層和草地較大，林地較小；飽和含水量和田間持水量以林地較大，農地亞表層和草地較小；萎蔫濕度則以林地較大，農地和果園地較小。
The physical and chemical properties of the soil were analyzed , including nutrient change and routine index of acidity and alkalinity , in addition , compared them with natural soil and studied their variation and correlation . the results as follows : the soil bulk density of harbin urban vegetation is higher , total porosity and field capacity are small 對其土壤的理化性質和養分狀況等指標進行分析，并與松花江地區自然黑土進行了對比，研究其變化的趨勢和養分相關性。結果表明：哈爾濱城市綠地土壤容重較大，孔隙度和田間持水量少，有機質缺乏，養分含量較低，相關性差，土壤ph值呈中性，肥力水平低。
It was found that the soil physical properties had significant spatial variability in the catchment scale because of the joint - influences of land use , topography , physiognomy , and other factors . the spatial variation is small for field capacity , moderate for wilting moisture and bulk density , and great for saturated soil moisture 受地形地貌和土地利用等因素的綜合影響，土壤物理性質在流域尺度內存在顯著的空間變異，飽和含水量的空間變異性最大，土壤萎蔫濕度和土壤容重居中，田間持水量空間變異最小。
The soil physical properties have obvious vertical distribution characteristic in the slope . the bulk density in sunlit slope is greater than it in sunless slope , and change in the follow order in the slope : top < middle < lower . while saturated soil moisture , field capacity , and wilting moisture are on the contrary 在地形上，土壤物理性質具有明顯的垂直分布規律，陰坡除土壤容重外，飽和含水量、田間持水量和萎蔫濕度均大于陽坡；同一坡度和坡向下，容重從坡下向坡上遞增，飽和含水量、田間持水量和萎蔫濕度均從坡下向坡上遞減。
The objectives of this study are : ( 1 ) collect the basis data about soil physical properties , soil moisture , infiltration and evapotranspiration in the catchment scale for developing a catchment hydrological model , based on the dtm , ( 2 ) provide the hydrological information in the catchment scale for developing agricultural production , vegetation rehabilitation , and reasonable land using in this region . the main conclusions drawn from this study are : ( 1 ) the soil physical properties , including bulk density , saturated soil moisture , field capacity , and wilting moisture , were measured at 56 plots across the catchment 為此，本文以黃土高原溝壑區典型小流域?王東溝為研究對象，通過大量的野外測定和室內分析，系統研究了流域土壤容重、土壤飽和含水量、田間持水量、萎蔫濕度、土壤入滲性能、土壤含水量和蒸散量的空間變異性，以期為該區農業生產、植被恢復和土地合理利用等提供科學的依據，同時為建立基于數字高程模型( dtm )為基礎的流域水文模型積累基礎資料。
According to physiognomy , the bulk density changed as the following order : upland > hills > hillslopes > gully slopes , the saturated soil moisture arranged as : hillslopes > hills > gully slopes > upland , while field capacity and wilting moisture are as follows : gully slopes > hills > hillslopes > upland 在地貌上，土壤容重呈現出塬面梁頂溝坡梁坡，飽和含水量呈現出塬面溝坡梁頂梁坡，田間持水量和萎蔫濕度均呈現出溝坡梁頂塬面梁坡的趨勢。
The field capacity and porosity increase gradually and bulk density decrease gradually . the significance linear regression between the field capacity and soil organic matter is discovered as well as porosity and bulk density 此外，隨植被演替， 0 5cm土層田間持水量和孔隙度逐漸增加， 0 5cm土層容重逐漸降低，且均與有機質含量呈顯著線性正相關。

The threshold value of soil water contents for photosynthesis and stomatal resistance is about 14 ( 0g ) , i . e . , 60 65 of field capacity 棉花的光合速率和氣孔阻力隨土壤含水量變化的閾值約在14土壤含水量水平，該閾值相當于田間持水量的60 65 。

Water content at field capacity is usually expressed as a percentage of the weight or volume of oven - dry soil 土壤含水量一般用干土壤的重量或體積百分比來表示，它受土壤質地的影響。

Field capacity the point at which the soil contains all the water it can hold by capillary and chemical attraction 田間持水量：土壤通過毛細作用和化學吸力可維持的全部水量。

Any more water added to soil at field capacity would drain away by gravity 超過田間持水量的所有添加的水分的都會由于重力作用而流失。

Field capacity field moisture capacity 田間持水量

Soil at field capacity has a high water potential 土壤處于田間持水量時通常有很高的水位。

Field capacity is a property of a unit volume of soil . 野外容水率是單位土體的一種特性。
