陕西汉中盆地水稻冷害初探

ELEMENTARY RESEARCH ON DAMAGE TO RICE DONE BY LOW TEMPERATURE IN HANZHONG BASIN OF SHAANXI PROVINCE

中文摘要:

      本文采用“多重比较”检验、方差分析和回归积分方法,求算了水稻冷害的温度指标,确立了产量预报的积分经验公式和温度影响产量的时间函数i(t),从而揭示了水稻产量和温度分布状况的定量关系,为稳产高产提供依据.

英文摘要:

      In this paper, by twice comparative examinations analysis of variance and regressive integration, the temperature scale on damage to rice done by low temperature is calculated; the empirical formula of integration of yield forecast and the time function i(t) which shows the influence of temperature to yield are established; therefore the quantitative relation of rice yield and temperature distribution is revealed; and this will provide the foundation for steady and high production.
