摘要:

在大田栽培条件下研究了不同时期喷施不同生化调节剂复配剂对优质杂交晚籼稻隆晶优570产量及抗倒性的影响。结果表明,单仅在拔节期或者在拔节期和始穗期两次喷施多效唑、调环酸钙等生化调节剂,可以明显缩短隆晶优570基部节间长度,增强其抗倒伏能力,增产效果显著;仅在始穗期喷施生化调节剂对提高抗倒伏能力和产量方面与喷清水对照相比有一定效果,但差异不显著。

关键词: 优质杂交稻, 生化调节剂, 抗倒伏, 产量

Abstract:

The effects of spraying different biochemical regulators at different periods on the yield and lodging resistance of high-quality hybrid rice Longjingyou 570 were studied under field cultivation conditions. The results showed that spraying paclobutrazol, calcium diclofenac and other biochemical regulators compounds at the jointing stage or at the jointing stage and the heading stage significantly shortened the base internode length of Longjingyou 570, enhanced the ability to resist lodging, and significantly increased the yield. The treatment of spraying biochemical regulators only at the heading stage had a certain effect on lodging resistance and yield compared with the sprayed water treatment, but the difference was not significant.

Key words: high-quality hybrid rice, biochemical regulator, lodging resistance, yield
