气候生态因子对南昌县水稻产量的影响

Effect of the Eco-climate Factor on the Rice Yield in Nanchang County

通过对南昌县27年的日平均气温、积温、降水量、日照时数和实测产量进行5年滑动平均以及利用最小二乘法进行回归分析,得出气候生态因子与气象产量的关系。

In this article the relation betewwn meteorological yield of rice and each eco-climate factor was analyzed with EXECLL and SAS soft including the data of light,temperature and rain factor.The results was that in the course of rice growth,when the average air temperature per day was in rising,the rice yield in Nanchang county was presenting downtrend. The meteorological yield presented positive correlation with the average air temperature per day, same as the accumulated temperature and sunshine. And it was the inverse correlation with the rainfall. The regressive model was marked between every climate factor and weather yield.
