通过试验作者系统分析了密度与水稻生育性状之间的关系及其变动幅度,认为在我省辽河下游一般栽培条件下水稻最高分蘖能力约为本株的2.5～8.0倍;单位面积上所能容纳的最高穗数多在每平方米800～1000苗之间;生物学产量每亩可能达到2400厅左右;对日光能的利用在3.5%左右;经济系数变动在0.32～0.62之间;密度和稻谷的产量之间的关系一般多呈抛物线形的曲线关系。
The relationship between the density and the fertility traits of rice was systematically analyzed by the author of the experiment. The maximum tillering ability of rice under the general cultivation conditions in the lower reaches of Liaohe River in our province was about 2.5 ~ 8.0 times that of the plant. The unit area could accommodate The highest spike number per square meter more than 800 to 1000 seedlings; biological yield per acre may reach about 2400 hall; the use of solar energy is about 3.5%; economic coefficient changes between 0.32 ~ 0.62; density and rice The relationship between the yield is generally parabolic curve.
