寡聚酸钾泡腾片对小麦早衰及产量的影响

Effects of Potassium Oligosaccharide Acids Effervescent Tablet on Premature Senescence and Yield of Wheat

以石新828小麦品种为试材,研究了在小麦齐穗期喷施不同浓度寡聚酸钾泡腾片溶液对小麦叶片叶绿素含量、穗粒数、千粒重和产量的影响。结果表明:在小麦齐穗期喷施寡聚酸钾泡腾片溶液,能够提高小麦叶片的叶绿素含量,有利于防治小麦早衰,小麦成熟后穗粒数和千粒重提高,最终有效提高小麦产量。其中对小麦穗粒数的影响大于对小麦千粒重的影响,说明喷施寡聚酸钾泡腾片主要是通过增加小麦穗粒数和穗粒重而使小麦产量提高的。总体来看,在小麦齐穗期喷施寡聚酸钾泡腾片10 000倍液,对防治小麦早衰和提高产量效果最为显著。

Using wheat variety Shixin 828 as the test material,the effects of spraying different contents of potassium oligosaccharide acids effervescent tablet on the chlorophyll content,grain number,1 000-grain weight and yield of wheat at full heading stage were studied.The results showed that the chlorophyll content could be increased,the premature senescence could be prevented,the grain number and 1 000-grain weight could be increased,which would increase the yield.The effects of potassium oligosaccharide acids effervescent tablet on the grain number was greater than that on 1 000-grain weight.Spraying 10 000 times potassium oligosaccharide acids effervescent tablet at full heading stage could prevent the premature senescence and increase the yield of wheat significantly.
