利用河南省安阳市夏谷产量和相应的气象资料,分析了2003～2012年降水量对豫北优质夏谷新品种产量的影响。结果表明,5～7月份降水量对夏谷产量影响最大,相关系数为R=0.982 04(R2=0.964 4),达极显著水平,相关回归方程Y=0.738 8X+159.991 0,该研究结果为充分利用当地气象条件、选育优质夏谷品种及其优质丰产提供科学依据。
Using the output of summer valley and corresponding meteorological data in Anyang City, Henan Province, the effect of precipitation from 2003 to 2012 on the yield of new varieties of high quality summer valley in North Henan was analyzed. The results showed that the precipitation from May to July had the most significant effect on the yield of summer cereal. The correlation coefficient was R = 0.982 04 (R2 = 0.964 4), reaching the significant level. The correlation equation was Y = 0.738 8X + 159.991 0. Make full use of local meteorological conditions, breeding high-quality summer valley varieties and their high yield and provide scientific basis.
