高产小麦的研究与培育是目前国内外农业研究的重点和难点之一,其中导致产量减少的主要原因是小麦的倒伏问题.针对小麦的抗倒伏问题,先分别建立了2007年、2008年和2011年的抗倒伏指数模型,并运用相关性分析和通径分析得出影响抗倒伏指数的最主要因素,再运用粒子群算法解决了不同株型结构的设计问题,最后分别讨论了小麦在重力和风载作用下的临界载荷问题,并给出了不同品种根倒和茎倒的临界风速.
The research and cultivation of high-yielding wheat is one of the most important and difficult problems in agricultural research both at home and abroad. The main reason for the decrease in yield is the lodging of wheat.For the lodging resistance of wheat, we first established 2007, 2008 and 2011 respectively Year lodging index model, and the use of correlation analysis and path analysis of the lodging resistance index of the most important factor, and then the use of particle swarm algorithm to solve the design of different plant-type structure, and finally discussed the wheat in the gravity and wind Critical load under the action of load, and given the different varieties of root and stem down the critical wind speed.
