中文摘要:

为研究不同栽培模式及生态条件对弱筋小麦籽粒品质的影响，以8个扬麦系列和宁麦系列弱筋小麦品种及2个中筋小麦品种为材料，分析参试小麦品种在不同栽培模式及生态条件下籽粒容重、蛋白质含量及淀粉含量的稳定性及差异性。结果表明，小麦籽粒品质既受品种遗传因素的控制，也受栽培模式及生态条件的影响。在弱筋小麦优质栽培模式［基本苗2.40×10⁶株·hm^-2，施用纯氮180 kg·hm^-2，磷、钾肥以基苗肥为主，氮肥运筹按基肥∶苗肥∶拔节肥（倒3.5叶前）=7∶1∶2］,弱筋小麦籽粒蛋白质含量较低,容重大,淀粉品质较高，中筋品种扬麦25和扬麦28也能够达到优质弱筋的要求。在中筋小麦高产栽培模式(基本苗1.80×10⁶·hm^-2，施用纯氮240 kg·hm^-2，磷、钾肥以基苗肥为主，氮肥运筹按基肥∶苗肥∶拔节孕穗肥=5∶2∶3)下，参试品种籽粒蛋白质含量均较高，多数品种不能达到弱筋小麦的标准。要保证弱筋小麦品质，应选择适宜良种，在常规大田栽培措施的基础上，采用第一种栽培模式，并根据当地当年气候生态条件作适当调整。

英文摘要:

To study the effects of different cultivation modes and ecological conditions on the grain quality of weak gluten wheat, 8 Yangmai series and Ningmai series weak gluten wheat varieties and 2 medium gluten wheat varieties were used as materials to analyze the stability and differences of grain bulk weight, protein content, and starch content of weak gluten wheat under different cultivation modes and ecological conditions. The results showed that the quality of wheat grains is not only controlled by genetic factors of the variety, but also influenced by cultivation modes and ecological conditions. Under different ecological conditions, the high-quality cultivation mode of weak gluten wheat was based on a basic seedling of 2.40×10⁶plants·hm^-2, pure nitrogen of 180 kg·hm^-2, and phosphorus and potassium fertilizers mainly based on basal and seedling fertilizer. The nitrogen fertilizer was based on basal fertilizer:seedling fertilizer:jointing fertilizer (before 3.5 leaves)=7∶1∶2. Under this cultivation mode, weak gluten wheat showed low protein content, good grain bulk weight, and high starch quality. Medium-gluten varieties Yangmai 25 and Yangmai 28 could also meet the requirements of high-quality weak gluten. The high-yield cultivation mode was based on a basic seedling rate of 1.80×10⁶plants·hm^-2, with pure nitrogen of 240 kg·hm^-2. Phosphorus and potassium fertilizers were mainly based on basal and seedling fertilizer, and nitrogen fertilizer was based on basal fertilizer: seedling fertilizer: jointing and booting fertilizer=5∶2∶3. The tested varieties showed high protein content in their grains under this cultivation mode, and most varieties can not meet the standards of weak gluten wheat. To ensure the quality of weak gluten wheat, suitable varieties should be selected, and the first cultivation mode should be adopted based on conventional field cultivation measures, and appropriate adjustments should be made according to the local climate and ecological conditions of the year.
