黄土丘陵草地土壤营养元素含量迁移及分布
- Title:
- The Content Movement and Distribution Characteristics of Main Soil Types Nutrient Elements in Hilly Loess Plateau
- 摘要:
- 系统研究黄土丘陵草地土壤理化性质、草地和农地营养元素迁移与富集，以及土壤养分剖面分布特征的基础上，试验结果表明：黄绵土、灰钙土及黑垆土为黄土丘陵区主要土壤类型；（2）黑垆土与黄绵土土壤颗粒组成含量差异较大，黑垆土成壤过程有隐粘化现象；（3）黑垆土表层及深层养分含量普遍高于黄绵土；（4）土壤养分在坡面与土壤剖面呈指数分布，土壤有效N、P、K含量北坡>西南>南坡；（5）提高草地生产力，防治土壤肥力退化的根本途径是增加草地养分输入，（6）提高豆科牧草对土壤深层养分的利用，可实现“生物聚肥”效应，培肥土壤。
- Abstract:
- Based on the systematic researches on soil physical and chemical properties of main soil types, the movement and enrichment of soil nutrient elements in farmland and grassland, and nutrient distribution on slopeland and in soil profile, the research results revealed: (1) The hilly loess plateau mainly distributed Heilu sol, loess soil and sierozem. (2) Heilu soil differed from loess completely in the soil textual composition, meanwhile. (3) The nutrient contents of top and profile of heilu soil were higher than that of loess soil generally. (4) Soil nutrient distributions on slopeland and soil profile presented exponent equation. (5) The essential approaches to raise grassland soil fertility and to prevent soil nutrient from deterioration were to increase nutrient elements inputs. (6) To enhance nutrient uses of Legume meadows in deep. soil Layer realized the effects of biological absorbtion to deeper layer nutrient elements, and fertilized soil.
