黄河三角洲耐盐小麦引种筛选试验初报

目的]黄河三角洲中心城市东营市有大面积的滨海盐渍土,需筛选适宜盐渍土栽培的小麦品种.方法]引进9个耐盐、抗逆、高产的小麦品种(系),以德抗961为对照,在全盐含量3～4 g/kg盐渍土上进行初步筛选试验.结果]济南18号、盐鉴14品系、山融3号产量都显著高于对照德抗961,这3个品种(系),成熟期都在6月13号以前,生育期适中,不影响下茬作物播种.结论]济南18号、盐鉴14品系、山融3号均适合在黄河三角洲轻、中度盐碱地推广种植.

Introduction and Selection of Salt-tolerant Wheat in Yellow River Delta

Objective] This study was to screen a salt-tolerant wheat variety in Dongying,a city in the center of the Yellow River Delta with a large area of coastal saline soil.Method] Total 9 salt-tolerant,stress-resistant and high-yielding wheat varieties (lines) were introduced,and they were cultivated in the saline soil with total salt content of 3-4 g/kg with Dekang 961 as the control.Result] The yields of Jinan 18,Yanjian 14 and Shanrong 3 were all significantly higher than that of Dekang 961 (P＜0.05).These three varieties (lines) all ripen before June 13 with moderate growth period that does not affect the seeding of next-season crop.Conclusion] Jinan 18,Yanjian 14 and Shanrung 3 are suitable for planting in light and median saline soil in the Yellow River Delta.
