劲丰与多效唑对小麦抗倒性及产量的影响
Effects of Jinfeng and Paclobutrazol on Lodging Resistance and Yield of Wheat
摘要
Abstract
The results of comparative experiments in wheat field showed that applying Jinfeng at the initial heading stage could significantly decrease the plant height of wheat, shorten the length of ear - stem burl and converse second burl, increase the width and wall thickness of each burl, shift down the barycenter of wheat plants, thus enhance the lodging resistance of wheat plants; it could also increase the grain number per ear and 1000 -grain weight, therefore obtain 7.01% more yield than CK. Applying Paclobutrazol at the jointing stage had no obvious effect on reducing the plant height, but it could shorten the length of basal stem burls, increase the width and wall thickness of basal stem burls, move down the center of gravity of wheat plants, but acquire 10. 71% less yield than CK. Both the application of Jinfeng at the jointing stage and the application of Paclobutrazol at the initial heading stage did not have obvious influences on plant height, burl length, burl width, burl wall thickness and yield of wheat.关键词
