砂土、壤土、粘土等就是土壤质地的名称,它是表示土壤砂、粘程度的。不同的土壤质地肥力性状等特征也不相同。如砂土、通气透水性好,保水、保肥性差;养分含量低、施肥见效快、土温变幅大,耕作性能好、苗期生长好,但后期易脱肥早衰。一般宜安排种植生育期短的作物和耐旱耐瘠韵作物。如高粱、谷子、胡麻及薯类作物等。粘土通气透水性差,保水保肥性强,养分含量较高,肥效时间长,土温变幅小,耕作性能差,苗期苗势弱,但有后轻,粘土一般适宜种植需肥较多的禾谷类作
Sand, loam, clay, etc. is the name of the soil texture, which means that the soil sand, viscosity level. Different soil texture and other characteristics of fertility are not the same. Such as sand, aeration and water permeability, water, fertilizer and poor; low nutrient content, fertilizer quickly, soil temperature amplitude, good farming performance, seedling growth, but the late easy to take off the premature. Should generally be arranged to plant short-growing crops and drought-resistant barren plants. Such as sorghum, millet, flax and potato crops. Clay is poor in aeration and water permeability, has high water and fertility, high nutrient content, long time of fertilizer effect, small amplitude of soil temperature, poor farming performance, weak seedling stage, but light afterwards.
