单季杂交水稻协优46,分别亩用烯效唑颗粒剂0.5kg、1kg和1.5kg处理,结果表明,所有处理的水稻植株基部节间缩短、变粗,从而增加了水稻的抗倒能力。植株的递矮程度随着使用剂量的提高而增加,使用剂量每增加0.5kg。植株递矮约5cm。水稻纹枯病减轻,结实率和千粒重增加,因而提高了水稻的产量。其产量的提高亦随使用量的增加而增加。从综合因素考虑,认为亩用药量以1kg为宜。
The single-season hybrid rice Xieyou 46 was treated with uniconazole granules 0.5kg, 1kg and 1.5kg, respectively. The results showed that all internodes of rice plants were shortened and thicker, which increased the lodging resistance of rice. The degree of plant dwarfing increases with the dose used, with an increase of 0.5 kg per dose. Plant delivery dwarf about 5cm. Rice sheath blight alleviation, seed setting rate and 1000-grain weight increase, thus increasing the yield of rice. The increase of its output also increases with the increase of the amount used. Considered from a comprehensive factor, that the amount of mu to 1kg appropriate.
