摘要:

玉米籽粒脱水与气象因子之间存在密切的关系, 明确影响籽粒脱水的主要气象因子及其影响程度, 能够更好地预测籽粒含水率的变化动态, 对筛选玉米机械粒收品种, 从而合理安排粒收时间等具有重要的实践价值。本研究于2015—2017年在河南新乡进行, 选用4个目前当地生产中主栽玉米品种京农科728 (JNK728)、郑单958 (ZD958)、先玉335 (XY335)和农华816 (NH816), 通过连续测定获得玉米籽粒含水率的变化过程, 并利用Logistic Power模型拟合, 借鉴去趋势的分析方法, 将玉米籽粒的实际含水率分为趋势含水率、气象含水率与随机误差, 明确黄淮海区域夏玉米籽粒的气象含水率与气象因子之间的关系, 利用逐步回归和通径分析的方法筛选出玉米籽粒生理成熟前后影响籽粒脱水的主要气象因子。分析发现, 玉米籽粒气象含水率与研究分析的大部分气象因子呈显著或极显著相关; 生理成熟前筛选得到的主要气象因子为平均温度(x1)、平均风速(x5)和蒸发量(x11), 生理成熟后为平均温度(x1)和平均相对湿度(x7), 回归模型均达到极显著水平; 通径分析表明, 生理成熟前蒸发量的贡献最大, 而温度、风速主要通过蒸发量起间接作用, 生理成熟后温度和相对湿度主要为直接作用, 且相对湿度的作用略大于温度。本研究所用去趋势的方法, 从理论和实际操作层面均更具科学性, 其研究结果也更为可信, 对其他类似研究也具有借鉴意义。

Abstract:

There is a close relationship between maize grain dehydration and meteorological factors. Clarifying main meteorological factors and their influence on grain dehydration can better predict the dynamics of grain moisture content, and the rationally arrange the time of maize grain harvesting. The study was conducted in Xinxiang, Henan province from 2015 to 2017. Four main maize varieties Jingnongke 728 (JNK728), Zhengdan 958 (ZD958), Xianyu 335 (XY335), and Nonghua 816 (NH816) currently planted in local production were selected to continuously measure the changes of maize grain moisture content. The logistic power model was used for fitting the process of grain dehydration and the removing trend method was used for analysing the results. The actual moisture content of maize grain was divided into trend moisture content, meteorological moisture content, and random error. The relationship between meteorological moisture content and meteorological factors in the Yellow-Huai-Hai Rivers area was clarified. The main meteorological factors affecting grain dehydration before and after physiological maturity of maize grain were screened out stepwise regression and path analysis methods. The meteorological moisture content of maize grain had significant or extremely significant correlation with most meteorological factors which were average temperature (x1), average wind speed (x5) and evaporation (x11) selected before physiological maturity, and the average temperature (x1) and the average relative humidity (x7) selected after the physiological maturity. The evaporation most contributed before the physiological maturity, while temperature and wind speed had indirect effect through evaporation. After physiological maturity, temperature and relative humidity were mainly direct effects, and the effect of relative humidity was slightly greater than that of temperature. The removing trend method used in this study is more scientific in both theoretical and practical operations. The results are also more credible and this method is of reference value to other similar researches.

Key words: summer maize, grain dehydration, moisture content, meteorological factors, removing trend analysis
