| 摘 要： | 作者应用典型相关分析,提出烟单14号夏玉米田间生态系各系统间的相关模型。结论是:播前土壤养分与植株体内养分的相关,主要表现在因果关系土壤中全氮的含量与小喇叭口期植株体内含氮和大喇叭口期体内含磷量的相关。施肥对植株体内养分的作用是在开花后才明显地显示出来的,主要表现在施氮肥促进开花后体内氮的增加、制约体内氮、磷含量的配合。影响产量的气象因素主要是开花前的光照时数和开花后的积温。

| Abstract: | The correlation models of subsystems in the field ecology system of summer corn are studied by the use of the canonical correlation analysis in this paper. The results are as follows:The correlation between the soil nutrient before sowing and the nutrient component structure in the plant body is shown by the correlation between the total nitrogen in the soil and the nitrogen amount of the plant body during small trumpet and the phosphorus amount of plant body during large trumpet.The effect of fertilization on nutrient component structure in the plant body is not evident until fiorescsnce. the application of nitrogen can promote the increase of nitrogen amount, while coordinatiing nitrogen and phosphorus in the plant body.The major weather factors affecting yield are light before florescence and accumlated temperature after florescense. |
