在生产实践中,早稻产量波动较大。这是由于早稻产量的形成过程受着肥料、病虫害、耕作技术水平和气象条件等的影响结果。为鉴定本地区影响早稻产量形成有利与不利的气象因子及数量关系,以便预测早稻产量,为适时播种、品种合理布局及采取趋利避害等农业技术措施提供科学依据,我们对本站早稻广选三号七年共34个分期播种的平行观测资料进行了统计分析,探索在南宁这一特定的生态气候条件下,早稻产量与气象因子的关系。

In production practice, the output of early rice fluctuates greatly. This is because the formation of early rice yield is affected by fertilizers, pests and diseases, farming techniques and weather conditions. In order to identify the favorable and unfavorable meteorological factors and quantitative relationships that affect the yield of early rice in the region, in order to predict the yield of early rice, provide scientific basis for timely sowing, reasonable layout of varieties and agricultural technical measures such as avoiding disadvantages and avoiding disadvantages, A total of 34 staged seeding observation data were selected for statistical analysis in the 7th year of the 3rd selection to explore the relationship between the output of early rice and the meteorological factors under the specific ecological and climatic conditions in Nanning.
