摘要: 为揭示生物有机液体混合肥对陕北农牧交错区青贮饲草作物光合作用的影响,以甜高粱(Sorghum bicolor L.)为研究对象,通过盆栽控制试验,设置4种浓度的生物活性水(BMW)(B1、B2、B3和B4,分别为稀释600、400、200和100倍的BMW溶液)和3种浓度的Aidoora溶液(A1、A2和A3,分别为稀释1000、500和300倍的Aidoora溶液)的生物有机液体肥处理,测定比较了不同生物有机液体混合肥下甜高粱叶片叶绿素荧光特性。结果表明:在大多数单一液体肥和混合液体肥下,适宜浓度水平的BMW和Aidoora溶液均能显著提高甜高粱幼苗叶片的PSⅡ最大光量子效率(Fv/Fm)、PSⅡ实际光化学量子效率(ΦPSII)、光化学淬灭系数(qP)和表观光合电子传递速率(ETR),并降低了其非光化学淬灭系数(NPQ),且以有机液体混合肥的促进作用更显著,这说明施加生物有机液体肥后均能提高其叶片PSII光化学效率和光合电子传递速率,而降低了非辐射性热能量耗散。综上分析表明,B2A2相对于其他BMW和Aidoora混合液体肥有利于促进甜高粱幼苗叶片PSII光化学活性。

Abstract: To clarify the effect of mixed organic liquid fertilizer on photosynthesis of forage crops in agro-pastoral ecotone of northern Shaanxi, the chlorophyll fluorescence characteristics of Sorghum bicolor were investigated after fertilization four concentration BMW solutions (i.e. B1, B2, B3 and B4 is each for 600, 400, 200 and 100 dilution times of BMW solution) and three concentration Aidoora solutions (i.e. A1, A2 and A3 is each for 1000, 500 and 300 dilution times of Aidoora solution) under potted experiment conditions. The results showed that: moderate levels of mixed organic liquid fertilizer significantly increased the maximum PSII quantum yield (Fv/Fm), active photochemical efficiency (ΦPSII), photochemical quenching (qP) and apparent electron transport rate (ETR), but significantly decreased the non-photochemical quenching (NPQ) in leaves of Sorghum bicolor under most single liquid fertilizer or mixed liquid fertilizer conditions, and the effects of mixed liquid fertilizer were more significant than single liquid fertilizer, which indicated that mixed organic liquid increased the PSII photochemical efficiency and apparent electron transport rate, but decreased the non-radiative energy dissipation. These results suggested that B2A2 was the most suitable mixed organic liquid fertilizer of the BMW and Aidoora solutions, and it could improve the PSII photochemical activity in the seedling leaves of Sorghum bicolor.
