耕地自然质量等级与土壤主要肥力指标的关系
The relationships between the natural quality grade of arable land and main soil fertility indicators
摘要
Abstract
Objective]The relationships between arable land natural quality grade and main soil fertility indicators were studied .[Method] Arable land quality monitoring indicators and the soil fertility indica-tors were investigated after the study area was divided into four monitoring partitions and 38 sampling points were laid , based on the work of Huazhou arable land quality grade monitoring .[Result and con-clusion]The results showed that the mathematical relationship between the arable land quality level ( y) and the main soil fertility indicators [ pH ( x1 ); available nitrogen content ( x2 ) ] was y =1 300.15 +630.33x1 +3.24x2 .pH and available nitrogen significantly are correlated with ten original monitoring in-dicators of arable land , and the two fertility indicators and the natural quality grade index also have a sig-nificant linear relationship .关键词
