为探求水稻功能型叶面肥的适宜配方,研究了抽穗期喷施不同配方功能型叶面肥对杂交水稻功能叶生理特性和产量的影响。结果表明,喷施4种不同配方功能型叶面肥后,水稻功能叶的叶绿素含量、超氧化物歧化酶(SOD)及硝酸还原酶(NR)活性、干物质及可溶性糖含量均比对照(喷施清水)不同程度提高,而丙二醛(MDA)含量比对照降低;4种不同配方功能型叶面肥均能提高水稻产量,增幅0.57%～5.20%。配方3处理能有效提高水稻生育后期功能叶的生理活性,促进干物质的积累,显著提高产量,为最佳配方。
In order to explore the suitable formula of rice functional leaf fertilizer, the effects of spraying different functional leaf-type fertilizer on the physiological characteristics and yield of functional leaf of hybrid rice at heading were studied. The results showed that chlorophyll content, superoxide dismutase (SOD) and nitrate reductase (NR) activity, dry matter and soluble sugar contents of functional leaves of rice were significantly higher than those of control ( Sprayed with clear water) increased to some extent, while the content of malondialdehyde (MDA) decreased compared with the control. Four kinds of functional foliar fertilizers could increase the yield of rice by 0.57% -5.20%. Formulation 3 treatment can effectively improve physiological activity of functional leaves in the late rice growth stage, promote the accumulation of dry matter and significantly increase the yield, which is the best formula.
