摘要

为探讨微咸水灌溉利用模式

在天津市静海县进行了微咸水灌溉试验

研究了微咸水灌溉对土壤盐分动态与作物产量的影响。结果表明

微咸水灌溉下

施用改良剂能提高土壤渗透性

降低土壤pH值和土壤电导率(EC)

降低了土壤含盐量

同时在试验周期0-60cm的土层内未出现积盐现象。此外

微咸水灌溉时

施用改良剂可显著增加小麦穗数和玉米穗粒数

提高作物产量。采用3.7g/L微咸水灌溉配合施用改良剂是该地区适宜的微咸水灌溉模式。

Abstract

To study the suitable strategies of saline water irrigation for crops

a field experiment was conducted in Jinghai County of Tianjin City.Data were collected to analyze the effects of saline water irrigation onsalt dynamics and crop yield.The results showed that with saline water irrigation

the application of soilamendment increased soil permeability coefficient

reduced soil pH value and EC(electrical conductivity ofsoil solution)

and decreased the salt content.No salt accumulation was found in 0-60cm soil during theexperiment.Meanwhile

the amendment increased wheat shoot number

grain number per shoot of maize andcrop yields significantly.Using saline water with degree of mineralization at 3.7g/L for irrigation with soilamendment is the recommended irrigation mode for crops in this region.
