通过选取中国作物网物质信息网上的2994条包括所需信息的小麦数据,进行通径分析,得到小麦产量因素对容重影响的方程式.选用数据里面的容重作为评判因素,因为容重可以作为小麦的等级评判标准,与小麦贮藏、出粉率等有关.本文讨论了小麦的株高、穗长、穗粒数、千粒重等对容重的影响.选用通径分析模型因为它可以同时得到小麦产量构成因素对容重的影响和各个因素之间的结构关系.通过得到的小麦籽粒容重关于各个因素的关系式,得出影响籽粒容重最大的因素,从而指导小麦育种专家选择出高品质的小麦品种,对小麦育种和生产都有指导意义.
By selecting 2994 wheat data including the required information from China Crop Net material information network, the path analysis was conducted to obtain the equation of wheat yield factors affecting bulk density.Using the bulk density in the data as the evaluation factor, the bulk density can be used as the wheat grade The evaluation criterion is related to the storage of wheat, the yield of wheat, etc. The effects of plant height, spike length, number of grains per spike, thousand-grain weight on the bulk density of wheat are discussed in this paper.With the path analysis model, The influence of bulk density and the structural relationship between the various factors.According to the relationship between each grain weight and weight of the obtained grain, the factors affecting the maximum bulk density of the grain are obtained, which guides the wheat breeding experts to select the high quality wheat varieties, And production are instructive.
