小麦高度和单株产量的空间分析及其对提高单产的意义

Spatial Analysis of Height and Yield of Wheat and Its Implications for Improving Yield of Per Unit Area

以宿州学院东区小麦为研究对象,对其高度和单株产量进行统计学和空间分析,以期为提高小麦单产提供参考。结果表明:1小麦的高度和单株产量均不呈正态分布;小麦在研究区北部和南部长势较好,而中部产量较高;2小麦高度和单株产量的变程当超过6.04 m和4.45 m时不再具有空间均一性;3小麦的高度和单株产量的块基比分别为21.6%和22.5%,均具有较强的空间自相关性;4小麦高度和单株产量超出142 cm和6.36 g时存在异常。由此得出,对于研究区而言,小麦种植的单垄在4.45 m以内时单产较高。

In this study,the height and yield of wheat in the east campus of Suzhou University had been analyzed by statistical and spatial analyses ,for obtaining the information about the improving of the yield of per unit area of wheat.The results indicated that ：0the height and yield of wheat were not normal distribution：the heights of wheat were higher in north and south but lower in the center, whereas the yields of wheat were higher in the center; 2spatial heterogeneities of height and yield of wheat were bruited to be 6.04 m and 4.45 re,respectively ;3the Nugget/Sill values of height and yield of wheat were 21.6% and 22.5%, which indicated that they were strongly dependent in spatial;4higher than 142 cm of height and 6.36 g of yield of wheat could be considered to be anomalies.These results suggested that the block of wheat cultivation should be limited to be 4.45 m in the study area, which could get higher yield of per unit area.
