水保所知识产出(1956---)知识库

黄绵土是陕北黄土丘陵沟壑区的主要耕种土壤，其特征为土层深厚，可储
存大量的雨水，被称为旱地作物成长的土壤水库。然而，由于降水偏少，加之水
土流失造成的土壤养分贫乏，土壤培肥就成为提高黄绵土生产力的重要措施。有
机无机肥料配合施用，连续施用化肥对作物的效益如何?对土壤性质有何影响?为
探究上述问题，陕西安塞农田生态系统国家野外科学观测研究站从上世纪 80 年代
开始进行不同土地类型的黄绵土连续施肥试验，在黄土丘陵沟壑区川地、梯田及
坡地分别布设了黄绵土连续施用不同肥料组合试验。本文整理了黄土丘陵区川地
黄绵土 1997–2011 年连续施用不同肥料组合试验的土壤水分数据。数据连续性好，
质量可靠，是进行土壤养分研究的重要基础数据。

Loessial soil is the major type of cultivated land in the loess hilly and gully area of northern
Shaanxi. It has a thick soil layer which can store a large amount of rainwater. It acts as the “moisture reservoir”vital for crop growth on dry land. However, due to lack of rainfall and soil nutrients caused by soil erosion,
the productivity of loessial soil has to be improved through artificial means, an important one of which is soil
fertilization. In order to explore the effects of continuous application of chemical fertilizer to crops, the Ansai
National Field Scientific Observation and Research Station has carried out continuous fertilization
Experimentation on different land types of loessial soil in the hilly and gully area of loess since 1980’s. The
experimentation has been carried out in tableland, terrace and slope fields. This paper presents a dataset of
soil moisture under continuous application of varied fertilizer combinations from 1997 to 2011. For its good
continuity and reliable quality, the dataset can support research on soil nutrients.
