| 中文摘要: |
| 通过盆栽试验,探讨了丁草胺施药量、施药时期、施药时水层深度对水稻分蘖的影响。结果表明:在供试水稻品种中施用丁草胺会降低其分蘖质量;在同一品种中,随施药量增加,分蘖数量减少;缓苗后施药比缓苗前施药的水稻分蘖多;施药时保持4 cm水层(未没过心叶)对水稻分蘖的影响小于保持8 cm水层(没过心叶)。初步明确了不同水稻品种对丁草胺的敏感性不同,本试验中的东农419水稻对丁草胺的敏感性高于绥粳4号。 |
| 英文摘要: |
| The experiments were carried out with potted rice to study the effects of butachlor with different dosages,treatment time and water depths on tillering of rice.The trial results indicated that butachlor application could reduce the quality of tillering.The higher the application dosage,the less the tillering number.Moreover,the tillering number of rice before the seedling recovery was less than that after the seedling recovery and the reduction rate of tillering in 4 cm water depth was lower than that in 8 cm water depth.The water depth submerging the heart leaves caused phytotoxicity to the rice more easily than the normal water depth.The susceptibility of different rices to butachlor was different in this experiment,and the susceptibility of Dongnong419 was higher than that of Suijing 4. |
