摘  要:
以水稻品种豫粳6号为试验材料,研究了在孕穗期喷施不同浓度(0、10、30、50、70mg/L)的ALA对水稻干物质积累、运转及产量的影响。结果表明,叶面喷施ALA后,能够促进干物质的积累和运转;提高水稻的结实率和粒重;使产量增加0.37%~10.19%,其中以喷施30mg/L的ALA效果较好。

摘  要:
Yujing 6 was used to study the effects of different concentrations(0,10,30,50,70 mg/L) of 5-Aminolevulinic acid(ALA) sprayed at booting stage on the dry matter accumulation,transportation and grain yield.The results showed that spraying ALA could promote dry matter accumulation and transportation,raise grain ripening percentage and grain weight,and increase yield by 0.37%~10.19%.The optimum concentration of ALA was 30 mg/L.
