Abstract
In this paper,the definition and computation of uniformity of plant distribution was given to describe quantitatively the plant distribution in crops field.Honeycombed arrangement of plants in the field is the most uniform planting pattern,for which distances in the vicinity of plants are all the same(including with the plant of different row in the vicinity).Therefore,the uniformity of plant distribution could be defined as percentage of an approximation to the honeycombed arrangement in the field.When a planting density is given,the uniformity of plant distribution could be obtained by calculating the uniformity deviation coefficient between the actual planting distance and the theoretical plant distance derived from the honeycombed arrangement.It is a composite index of planting pattern what it covers planting density,patterns of row spacing and plant spacing,and plant position in row,and is much better than row spacing only to reflect the status of crop arrangement in the field.It could provide a new priority to better understand the relationship between planting pattern and yield.And also,the integrated effects of row spacing and planting density on uniformity of distribution was analyzed.

Claim · model-written summary
The composite index covers density, row and plant spacing, and plant position and better reflects field arrangement than row spacing alone.
