摘 要 ：在多品种、多试点的田间分期播种和人工气候箱控温、遮光处理等试验的基础上 ,通过对影响稻米品质诸气候生态因子的相对重要程度及稻米品质形成与水稻灌浆结实期前 30 d的日均温度、日均太阳辐射间的关系进行分析 ,首先建立了稻米品质的温度评价函数 ,然后用分段法构建了稻米品质的日均太阳辐射量订正函数 ,将上述两式结合 ,则可得某一地稻米品质气候生态条件的综合评价函数。利用该公式 ,在全国选若干代表点计算其稻米品质的评价指标值 ,并以此为基础 ,分双季早籼、双季晚籼、单季粳稻与双季早粳、双季晚粳 4大类型描绘出我国不同气候生态条件下稻米品质的地域分布框架图。

Abstract:The effect of climatic factors on twelve quality traits of eleven rice varieties (japonica and indica) was studied in the field as well as growth chambers. The field trials comprising 10～14 sowing dates were conducted at thirteen locations representing six diverse climatic regions of China. Six shading treatments were imposed on plants at full heading stage. Shading treatments consisted of 10, 25, 40, 55, 68, 80 per cent shaded area of plants and control. In another study, rice plants were transferred from ...
