本文运用全国有代表性的水稻品种在全国种植的生育期资料,提出不同生育期以及不同品种从播种到抽穗的气象生态模式,提出水稻三大类型1、早籼,早粳,2、中籼,中粳,3、晚籼、晚粳的不同模式类型。指出了生育期的气象生态模式具有重要的应用价值,运用模式计算的生育期误差和有效积温法的误差相比较,对感光性弱品种精度要提高三天左右,对感光性中等的品种要提高6—12天,对感光性强的品种则提高18—20天。
In this paper, we use the growing season data of representative rice varieties nationwide to propose the meteorological and ecological models of sowing and heading at different growth stages and different varieties. Three types of rice, ie early indica rice, early japonica rice, 2, medium indica rice, , Middle japonica rice, 3, late indica rice and late japonica rice. Pointed out that the meteorological and ecological model during the growth period has an important application value. Compared with the error of the effective accumulated temperature method, the error of the growth period calculated by the model is about three days for the sensitive and weak varieties, 6-12 days, for the more sensitive varieties are increased 18-20 days.
