中文摘要:为分析豫西不同栽培环境对优质小麦品质性状的影响,选取洛阳农林科学院育成的7个半冬性优质小麦品系‘HPG127’‘HPG164’‘HPG165’‘HPG167’‘HPG513’‘HPG542’‘HPG521’和2个优质对照品种‘豫麦34’和‘藁麦8901’,在洛阳农林科学院3种栽培环境(旱薄地、旱肥地和水地)进行随机区组试验,统一收获其籽粒进行品质相关性状的测定。结果表明:体积质量、总湿面筋、总干面筋和粗蛋白质量分数这4个性状在不同栽培环境下差异显著,主要表现为高肥力能降低小麦体积质量,灌水会稀释粗蛋白质量分数,水地栽培环境中面筋含量最低。对变异系数最大的稳定时间进一步分析表明:各品种(系)稳定时间变化趋势在3种栽培环境下不尽相同,旱肥地能增加大部分品种(系)的稳定时间,个别品种(系)在水地环境下稳定时间最长。综上所述,豫西地区优质小麦的栽培可通过控制灌水和施肥来保证小麦的面筋和粗蛋白含量,并结合具体品种的特性选择合适栽培环境以实现对品质的具体要求。

Effects of Different Planting Environments in Western Henan on Quality Traits of Strong-gluten Wheat
Abstract:To analyze the effects of different planting environments on the quality traits of strong-gluten wheat in western Henan,seven strong-gluten wheat varieties‘HPG127’‘HPG164’‘HPG165’‘HPG167’‘HPG513’‘HPG542’‘HPG521’ were bred by Luoyang Academy of Agriculture and Forestry.Two control strong-gluten wheat varieties ‘Yumai 34’ and ‘Gaomai 8901’ as experimental materials,it was cultivated by using field plot test in three experimental planting environments,including dry and infertile land,dry and fertile land and irrigated land,the quality-traits of the harvested grains were measured. The results indicated that four quality traits of volume mass,total dry gluten mass fraction,total wet gluten mass fraction and protein mass fraction had significantly difference in different cultivation environments,it showed that the higher fertility could reduce the volume mass, more water could decrease the protein mass fraction,the irrigated land had negative effect on the gluten mass fraction. The stability time had the maximum coefficient of variation,for the further analysis,the variation trend among wheat varieties was different in three planting environments,most of the varieties could had the longest stability time in dry and fertile land,but some varieties had the longer stability time in irrigated land. Above all,cultivation of the strong-gluten wheat can keep the gluten mass fraction by controlling irrigation and fertility in western Henan,suitable cultivation environments were selected to meet the specific requirements of quality according to the characteristics of specific varieties.
