摘要:

以软米粳稻南粳9108和常规粳稻淮稻5号为供试材料,通过不同播期和穗后遮光方式,设置轻低温、轻低温+弱光、低温和低温+弱光4种处理,以Ⅰ期播种并未进行遮光的处理为对照(CK),研究灌浆期低温弱光对水稻产量和品质的影响。结果表明,与CK相比,灌浆期低温弱光4个处理产量均显著降低;灌浆期轻低温和低温处理稻米加工品质和外观品质有所改善,而轻低温+弱光和低温+弱光处理则降低了稻米加工品质、外观品质和食味品质。

Abstract:

In order to explore the effects of low temperature and weak light during the filling stage on yield and quality of rice, we conducted an experiment using soft japonica rice Nanjing 9108 and conventional japonica rice Huaidao 5 as materials, set up four treatments through different sowing dates and conducting post panicle shading methods, including light low temperature, light low temperature + weak light, low temperature, and low temperature + weak light, take the treatment of sowing in the first stage without shading as the control (CK). The results showed that compared with CK, the yield of the four treatments of low temperature and weak light significantly decreased. Compared with CK, the processing quality and appearance quality of light low temperature treatment and low temperature treatment were improved, while the processing quality, appearance quality, and taste quality of light low temperature+ weak light treatment and low temperature+weak light treatment were reduced.

Key words: soft japonica rice, filling stage, low temperature and weak light, yield, quality
