为了研究硫肥对小麦群体生理、产量和品质的影响 ,以及对不同穗型品种的效应 ,通过随机区组试验 ,对豫麦 4 9(多穗型 )和兰考 90 6 (大穗型 )冬小麦品种进行了不同硫肥处理。研究结果表明 ,适宜的硫肥处理能够增大小麦的叶面积指数 (L AI) ,增加干物质的积累 ,提高群体光合 (CAP)速率 ,而且对于提高小麦穗粒数、结实率、千粒重、容重、粗蛋白含量、湿面筋含量也有较大的作用。两种穗型小麦品种对硫肥的反应有差异 ,多穗型的豫麦 4 9施硫后 ,产量提高幅度较大 ,而品质反应不明显 ,大穗型品种兰考 90 6的产量和品质对硫肥的反应却相反 ,因此硫肥施用应考虑品种间差异。
In order to study the effects of sulfur fertilizer on the physiological, yield and quality of wheat populations and their effects on different panicle types, the effects of sulfur fertilizer on wheat populations were studied by randomized block experiments. Varieties were treated with different sulfur fertilizers. The results showed that appropriate treatment of sulfur fertilizer could increase the leaf area index (L AI), increase the accumulation of dry matter, and increase the photosynthetic rate (CAP) of wheat population, and also increase the grain yield per spike, seed setting rate, , Crude protein content, wet gluten content also has a greater role. The response of the two panicle cultivars to sulfur fertilizer was different. The yield of the large panicle cultivar Lankao 906 was significantly higher than that of the control The response of sulfur fertilizer is the opposite, so sulfur fertilizer application should consider the differences among varieties.
