5-氨基乙酰丙酸叶面肥对杂交晚稻光合作用和产量的影响

Effects of 5-aminolevulinic Acid on Photosynthesis and Yield of Hybrid Late Rice

以4个杂交晚稻为材料,研究了齐穗期叶面喷施1 mg/L的5-氨基乙酰丙酸叶面肥对杂交晚稻生育后期叶片SPAD值、光合作用、干物质积累和经济产量的影响。结果表明:5-氨基乙酰丙酸叶面肥能提高水稻功能叶SPAD值、光合作用,增加干物质积累量,产量增加3.2%～4.0%。

Using four hybrid late rice varieties as materials,the effects of foliage spraying 1.0 mg/L of 5-aminolevulinic acid on leaf SPAD value,photosynthesis,dry matter accumulation and economic yield of hybrid late rice in late growth period.The results showed that 5-aminolevulinic acid can increase SPAD value of function leaves,photosynthesis,dry matter accumulation and yield of rice.The rice yield can increase by 3.2% to 4.0%.
