Abstract:

Different high-gluten wheat varieties from seven provinces were planted to study the yield and grain protein content by different spring irrigation treatment in this examination. The results indicated that the grain yield in-creased with the spring irrigation frequency increasing in the situation of spring drought, The yields of different varieties have extremely remarkable differences, the yield of Yannong 19 was the highest one and next was Jimai 20, Different varieties grain protein content reduced with the spring irrigation frequency increasing （ except wanmai 38 ）, The protein content have exxtremely remarkable differences under different varieties and irrigation treatments, the protein content of the Linyou 145 was the highest one and next was Gao 8901.

Key words: wheat ;irrigation, yield , protein

摘要：

选用来自7个省的不同强筋小麦品种,进行不同春季灌水处理,分析其产量和子粒蛋白质含量的变化。结果表明：在春季干旱的情况下,随着春季灌水次数的增加产量提高,不同品种间的产量差异极显著,以烟农19的产量最高,其次是济麦20。不同品种的子粒蛋白质含量随着春季灌水次数的增加而降低（皖麦38除外）,不同品种间、不同灌水处理间蛋白质含量差异极显著,以临优145的蛋白质含量最高,其次是8901-11。
