摘要
探讨了不同浓度多效唑在小麦 3个发育时期的喷施效果。结果表明 :施用多效唑可有效控制基部节间长度 ,单位长度干重增加 ,茎壁加厚 ,增强了小麦的抗倒伏能力 ;同时防止后期早衰 ,减少不孕小穗数 ,提高每穗实粒数和千粒重 ,增产 5 %～ 2 6%。
The spraying effect of pp333 with different concentration on wheat in different periods is discussed. The results indicated that the application of pp333 can effectively control the length of bottom internode, increase the dry weight per unit of length and the wall thickness of stem, thereby lodging resistance of wheat is increased. Meantime it can guard against the premature senility of later stage, reduce the numbers of sterile spikelet, enhance the numbers of gains per spike and thousand grain weight, increase the yield by 5% 26%.
