杀菌剂对弱筋小麦宁麦9号品质和产量的影响

为了探索弱筋小麦杀菌剂的使用方法,以弱筋小麦宁麦9号为材料,研究了杀菌剂(粉锈宁、多菌灵)抽穗期喷洒对小麦籽粒产量和品质的影响。结果表明,在宁麦9号抽穗期喷洒粉锈宁和多菌灵,均可以显著提高其穗数、千粒重和产量(P<0.05),其中喷洒粉锈宁的增产幅度显著高于喷洒多菌灵处理(P<0.05)。喷洒粉锈宁可以显著降低籽粒蛋白质含量(P<0.05),改善面粉白度。喷洒多菌灵能够显著降低籽粒蛋白质含量、湿面筋含量、面粉白度和沉降值(P<0.05),提高出粉率和面粉的心皮比(P<0.05)。

Effects of germicide on grain yield and quality of weak gluten wheat Ningmai 9

Weak gluten wheat variety Ningmai 9 was used as an experimental material to study the effects of germicide(triadimefon and carbendazim)on grain yield and quality of Ningmai 9 in heading stage.The results showed that the ear number,1 000-kernel weight and grain yield of Ningmai 9 sprayed with triadimefon and carbendazim in heading stage were significantly increased(P<0.05).The yield increase Ningmai 9 sprayed with triadimefon was significantly higher than that of carbendazim(P<0.05).Grain protein content of Ningmai 9 sprayed with triadimefon significantly declined(P<0.05),and flour whiteness was lightly improved.Grain protein content,wet gluten content,flour whiteness and sedimentation value of Ningmai 9 sprayed with carbendazim were significantly reduced(P<0.05),while flour yield and ratio of middling flour to breaking flour were significantly increased(P<0.05).
