| 摘 要： | 研究了不同时期喷施吨田宝对水稻生长发育和产量的影响。结果表明:喷施吨田宝,能降低水稻植株高度,从而有利于植株抗倒伏;同时,水稻分蘖数、叶片数、干物质积累、穗粒数、结实率、千粒重也均有所增加,产量得到显著提高;各处理中以以秧田期和拔节期各喷施一次吨田宝的处理增产效果显著,产量达9 138.40 kg/hm2,比对照增产725.92 kg/hm2,增产率达8.63%。

| Abstract: | The effects of different treatments on the growth, development and yield of rice were researched. The results showed that spraying Duntianbao, could reduce the rice plant height, which is conducive to the lodging resistance of plant. At the same time, the number of tiller, leaf number, dry matter accumulation, grain number, seed setting rate, 1000-grain weight were increased, and the yield was signiifcantly increased. The treatmment by spraying once Duntianbao in each seedling stage and jointing stage reached the highest yield of 9 138.40 kg/hm2. The yield was higher than that of control by 725.92 kg/hm2 and the growth rate was 8.63%. |
