| 摘 要： | 对在不同时期用不同浓度的多效唑(PP333)喷施小麦进行了研究。结果表明,不同浓度的多效唑能增加小麦的叶面积和叶绿素含量,增强小麦剑叶的光合作用,增加光合产物向茎秆和子粒的输送;不同时期用不同浓度的多效唑喷施小麦,对小麦第一、二、三节节间均有不同程度的控长作用,降低了植株的高度,从而提高了小麦的抗倒伏能力,为小麦产量的提高奠定了基础。

| Abstract: | Study was conducted on PP_(333) spraying wheat at different stages with different concentrations.Results showed that PP333 spraying wheat with different concentrations could increase the leaf area and chlorophyll content,enhance the photosynthesis of wheat flag leaf and promote the transportation of photosynthate to stem and grain.PP333 spraying wheat at different stages with different concentrations could control the growth of the first,second and third internode so as to reduce the plant height and improve the lodging resistant ability of wheat. |

| Keywords: | wheat PP_(333) lodging resistance technique of chemical control |
