| 摘 要： | 以贵农18号高产优质小麦品种为材料,设计不同的硫肥用量处理,比较分析各处理对小麦生理特征及品质的影响。结果表明:在0～48kg/hm2的施用范围内,硫肥能显著提高小麦植株的干物质积累量、根系活力、叶片硝酸还原酶活性、叶绿素含量和籽粒产量,并能明显改善小麦籽粒营养品质。相关性分析表明,小麦籽粒产量与硫肥施用量之间呈极显著正相关关系,相关系数达到0.9以上。在该试验条件下,硫肥施用量为48kg/hm2的处理是兼顾经济与社会效益的最佳选择。

| Abstract: | Taking Guinong18 as the tested material,different amount of sulfur fertilizer was designed to compare and analyze the effects of different sulfur fertilizer consumption on physiological characteristics and quality of wheat.The results showed that application in a range of 0～48kg/hm2 significantly increased dry-matter accumulation,root activity,leaf nitrate reductase activity,chlorophyll content and grain yield of wheat;meanwhile,it could significantly improve the wheat grain quality.The positive correlation was found between wheat yield and applying sulfur amount with the correlation larger than 0.9.In this experimental condition,the application level of sulfur fertilizer with 48 kg/hm2 was turn out the optimum choice to economic and social benefits. |
