- Title:
- The Soil Association of Land Types and the Change of Soil Nutrient on Way of Use
- 摘要:
- 上黄村土地类型有河滩、台坪、沟掌、梁和坡。土地类型对土壤养分变化的影响：有机质、全氮和水解氮是坡>阳坡>梁>台坪>沟掌>河滩>沟坡；磷钾是台坪、沟掌和河滩>台、阳坡、梁和沟坡。土地利用方式不同也影响土壤养分分布：（1）草地土壤养分变化是有机质、全氮和水解氮：为半阴半阳坡>阴坡>轮荒地>人工草地>农耕地，磷钾则相反，（2）台坪农地土壤养分呈放射状分布；（3）土壤微量元素的变化基本类似于磷钾。
- Abstract:
- The land types are flood land,platform, level ground, gouzhang, roof beam and slopes in Shanghuang village.The land of slopes was divided shady slope (yinpo), sunny slope (yangpo), halfshady—halfsunny slope (banyinbanyangpo) and goupo. The soil association of flood land,, platform, level ground and gouzhang are warp soil, heilo soil and xianghuang soil (yellow mein soil). The soil association of the roof beam and slopes are xianghuang soil (yellow mein soil), yinghuang soil and red soil. The complication of the land types influenced the not well-distribution of the soil nutrient. The law of change on the soil nutrient of the land types are:organic matter,total nitrogen and hydrolyzable nitrogen are slope sunny slope>roof beam>platform and level groung>(gouzhang)>flood land>(goupo). Phosphate and potassium are platform, level ground, gouzhang and flood land>slope, sunny slope (yanwa), roof beam and goupo. The different way of use influenced difference of the soil nutrient, organic matter, total nitrogen, and hydrolyzable nitrogen are: halfshady-halfsunny slope>sunny slope>rotation waste>man-made grass land cultivated land. Phosphate and potassium are contrary. The law of change on the soil nutrient of agricultural land of platform and level ground are the distribution of radiant form. The law of change on microelement is similar to phosphate and potassium.
