植物生长调节剂对机插水稻抽穗后茎秆性状及产量的 影响
Effects of Plant Growth Regulators on Yield and Stem Characters after Heading of Me-chanical Transplanted Rice
摘要
Abstract
The effects of plant growth regulators on plant height, internode length,stem characters and yield after heading of mechani-cal transplanted rice, using super rice variety Liangeng 7 as material. The results showed that aizhuangfeng and jinfeng could increase filled grains, seed setting rate and thousand grain weight. The yield of treatment which spraying 75 mL/667 m 2 aizhuangfeng was 49.63 kg/667 m2 higher than the control. Although paclobutrazol and uniconazole could reduce the plant height, improve the culm breaking-resistant strength and increase the seed setting rate and thousand grain weight, however the filled grains of the treatments of paclobu-trazol and uniconazole were significantly lower than that of the control, and finally did not achieve the purpose of increasing yield.关键词
