为阐明ALA对水稻产量因素和籽粒灌浆的影响,以水稻品种通239为材料,于不同生育时期,喷施不同浓度的ALA溶液,观察籽粒灌浆过程并调查各处理的农艺性状。结果表明,1）ALA处理能显著提高水稻的千粒重;2）ALA对水稻籽粒灌浆的影响较大,始穗期喷施低浓度的ALA,可明显提高水稻籽粒的灌浆速率;3）ALA处理能提高水稻籽粒的起始生长势,提早灌浆高峰。

To reveal the effect of ALA treatment on yield factors and grain filling of rice.Used Tong239 variety of rice as material to apply in different concentrations of ALA in different growing stages and researched grain filling process and agronomic traits.The results showed that ALA treatment on 1 000 grain weight improved significantly.The relationship between ALA and grain filling of rice were very closely.Lower concentration of ALA could significantly improved grain filling speed in initial heading stage.The ALA treatment could improve original growth potential and peak filling stage early.
