红枣滴灌条件下灌水水质对土壤盐分分布的影响研究
Research on the Effects of Water Quality on Soil Salt Distribution in Drip Irrigation for Red Jujube
摘要
Abstract
The objective of the experiment was to investigate the effect of difference mineralization degrees of irrigation water on soil water-salt dynamic under soil salt content for dwarfing and high-density culture of red jujube. Therefore, the result would have good application values in guiding saline water irrigation for red jujube. Field experiments were conducted for different treatments with spacing in the rows and spacing between rows about 1 m× 2 m red jujube, and to study the regulation of soil water-salt transport under subsurface drip irrigation. The results showed that all treatments decreased soil salt content mainly 0-40 cm soil vertical profile, but did not reduce soil salt content along horizontal direction. During the red jujube growth stage, saline water drip irrigation increases salt content mainly the soil 0-30 cm profile. The content of salt ions increased with water mineralization degree and soil salt content, mainly focused on high soil salt content and water mineralization. Saline water drip irrigation has leaching effect and can be used to irrigate salt-containing soil.关键词
