植物生长调节剂麦巨金对冬小麦产量及抗倒性的影响

Effects of Plant Growth Regulator Maijujin on Yield and Lodging Resistance of Winter Wheat

在小麦起身期喷施0.1%的麦巨金溶液,试验设喷施次数0次(清水,CK)、1次和2次3个处理,研究了麦巨金喷施次数对冬小麦产量及抗倒性的影响。结果表明:喷施植物生长调节剂麦巨金能够缩短基1节和基2节的节间长度,其中对基1节影响较大,最终显著降低株高,提高小麦的抗倒性;能够改善小麦的产量构成要素,其中对千粒重和穗粒数影响较大,最终提高小麦产量。在小麦起身期间隔10 d连续喷施2次麦巨金效果较好,不仅能够显著提高小麦的抗倒性,还能够显著减少无效小穗数,明显提高穗粒数和千粒重,最终显著提高小麦产量。

Effects of spraying times of 0.1% Maijujin at the getting-up stage on winter wheat yield and loading resistance were studied, and the spraying times were 0 （clean water, CK）, 1, 2 times.The results showed that the Maijujin could shorten the internode length of the first and second from basis , which greatly impacted the first internode form basis, and significantly reduced plant height, ultimately improved the loading resistance of wheat.Maijujin also could improve the yield components of wheat , which greatly impacted 1000-grain weight and grain number per spike, and ultimately improved the yield of wheat.The effects of sprayed two times interval of 10 days at the getting-up stage was better than that of one time, it could not only significantly improve lodging resistance , but also reduce the number of spikelets invalid , remarkably increase the grain number per spike and 1000-grain weight, and ultimately increase wheat production.
