滴灌方式下枣树测墒点布设位置研究
Study on the location of soil moisture measuring points on jujube trees under drip irrigation
摘要
Abstract
Soil moisture is a prerequisite for irrigation decision-making.In this study,the distribution of soil water content in the depth of 0-100 cm at four different sampling points near the drip head was observed through field experiments,and the optimal placement location of moisture measuring points for jujube trees in sandy loam soils was determined using R cluster analysis,classi-cal statistics t-test and geostatistics.The results showed that under different irrigation amount conditions,the soil water content mea-sured at different depths with the drip head as the center coordinate(0 cm,0 cm)gave the location coordinates,and the deploy-ment of monitoring points in its horizontal direction should not be more than 30 cm,and the coordinates of the optimal moisture measuring point at the T1 treatment were determined to be(25 cm,40 cm)according to geostatistical kriging interpolation method,and its relative average error was 0.69%,and the coordinates of the optimal moisture measuring point at the T2 treatment were(3 cm,73 cm),and its relative average error was 0.16%.The accuracy and applicability of the best moisture measurement point are good,which provides a certain reference for the deployment of soil moisture sensors in date fields.关键词
