一看土壤颜色。肥土土色较深;而瘦土土色浅。二看土层深浅。肥土土层一般都大于60厘米;而瘦土相对较浅。三看土壤适耕性。肥土土层疏松,易于耕作;瘦土土层黏犁,耕作费力。四看土壤淀浆性及裂纹。肥土不易淀浆,土壤裂纹多而小;瘦土极易淀浆,易板结,土壤裂纹少而大。五看土壤保水能力。水分下渗慢,灌一次水可保持6~7天的为肥土地;不下渗或沿裂纹很快下渗的为瘦土。六看水质。水滑腻、黏脚,日照或脚踩时冒大泡的为肥土;水质清淡无色,水田不起泡,或气泡小而易
A look at soil color. Soil dark soil color; and lean soil color shallow. Second, see the depth of soil. Soil and soil are generally greater than 60 cm; and the relatively shallow soil. Third, see soil adaptability. Loose soil loosening, easy to cultivate; lean soil plow, farming laborious. Fourth, see soil slurry and cracks. Soil is not easy to slurry soil, soil cracks more and more small; very easy to cast leatland soil, easy to knot, small and large soil cracks. Five to see soil water retention capacity. Moisture infiltration slow, irrigation water can be maintained for 6 to 7 days for the fertile land; no infiltration or rapid infiltration along the crack for the lean soil. Six to see the water quality. Water, creamy, sticky feet, sunshine or foot bulky bubble for the soil; light and colorless water, paddy fields are not blistering, or small bubbles and easy
