The empirical equation w = asb was used to fit water holding capacity of four kinds of agricultural soils in loess plateau. soil water holding capacity and unavailable water content increased as soil texture became clayed. available water content in loam was higher than those in sandy soil and clayed soil
黃土高原四種主要農業土壤的水分特徵曲線並無明顯的平臺或拐點產生，其關系能夠很好地用garden經驗方程（ w = as ~ （ - b ） ）進行擬合。 -
Determination of soil infiltration capability and water characteristic curves of sandy loam soil
沙壤土入滲性能和水分特徵曲線的測定 -
The number of 3 rhizosphere microorganisms ( bacteria, fungi, actinomycete ) and 5 enzyme ( catalase, protease, urease, phosphatase, invertase ) activities were studied during the whole life of corn plant in sandy loam, loam and clay soil textures. [ method ] using yedan22, the number of 3 rhizosphere microorganisms and 5 enzyme activities with different textural soils were investigated in a pond
摘要目的明確不同質地土壤（砂壤、中壤、重壤）玉米生育期間根際微生物（細菌、放線菌、真菌）數量與酶（脲酶、蛋白酶、磷酸酶、轉化酶、過氧化氫酶）活性的變化。 -

This research was conducted to : ( 1 ) understand the characteristic and pattern of trickle source infiltration, ( 2 ) study mulched crop evapotraspiration for cotton and corn in a arid climate sandy loam soils. according to the researches of the dissertation, the main results are as follows : ( 1 ) the shape of wetted soil volume is influenced by soil texture, discharge rate and the total volume of applied water in case of trickle source infiltration
本文以粘壤土為研究對象，對微源入滲特性規律進行了系統的室內試驗研究，並且對膜下滴灌大田作物棉花和玉米的需水規律進行了野外試驗，得到了以下幾點結論： （ 1 ）地表微源入滲土壤濕潤體的形狀受到土壤質地、供水強度和灌水時間的影響，一般為半個橢球體。 -
Under subsurface drip irrigation, soil wetted front movement when higher soil initial moisture content was quicker than that of when it is lower, so did the supplied water pressure and soil bulk density. the wetted front movement of clay loam was clearly slow than that of sandy soil, especially in the larger soil bulk density
地下滴灌條件下，初始含水量較高的土柱，濕潤鋒運移速度快于含水量較低的；在較高的供水壓力條件下，各個方向的濕潤鋒運移都比低水頭情況下的快；容重越大的土柱濕潤鋒運移速度越緩慢。 -
Loam a medium - textured soil containing a mixture of large and small mineral particles. loams are easy soils to work and combine the good properties of sandy and clay soils
壤土：一種中等密度的土壤，其中包含大小不同的礦物質顆粒。這種土壤利於種植，並具有沙土和黏土的優點。
