| 摘要: |
| 在水稻分蘖期和穗分化期喷施 MET,结果表明:MET 降低了植株高度,增加了下部节间的粗度,使叶片在植株上的分布更为合理,提高了植株中、下部的透光率,群体干物质生产增加,氧现为防倒增产的效果。 |

| EFFECTS OF PLANT GROWTH RETERDANT MET ON THE ARY MATTER PRODUCTION AND POPULATION CONSTRUCTION OF RICE |

| Abstract: |
| Rice Plant treated with MET had an obvious effect on dry matter production of rice population.It was the most important that the po- pulation construction of rice was changed by shortening length of bo- th leaves and internode of lower stem and making tilting angle of u- pper three leaves smaller-lodging of rice plant in later stage that was effective prevented by using MET.Colony growth rate(CGR)and net assimilation rate(NAR)in the later growth stage of rice were increa- sed by using MET.The penetrating li... |
