摘要: 为探讨食用菌菌渣与化肥不同配施比例对水稻光合性能和产量的影响,盆栽试验条件下,以水稻品种秀水134为试材,分别设置0,50%,100% 3个菌渣和化肥水平,共9个不同配施比例处理,测定孕穗—成熟期各处理剑叶的光合速率、SPAD指数变化,以及收获期产量及其构成因素的变化。结果表明:各生育时期剑叶叶绿素含量最高的为100%化肥+100%菌渣,光合速率最高的为100%化肥+50%菌渣;籽粒产量、生物产量最高的处理为100%化肥+100%菌渣。结果表明,菌渣与化肥配施,不仅提高了水稻灌浆期间功能叶片的光合作用,而且提高了水稻产量。

Abstract: In order to investigate the effect of edible fungus residue application with chemical fertilizer on photosynthesis characteristics of flag leaf and grain yield of rice, a pot experiment was carried out including 9 treatments with different proportions of edible fungus in combination with chemical fertilizers. The changes in photosynthetic rate and SPAD index of flag leaf during grain filling period as well as grain yield were also analyzed. The results were as follows: During the grain filling period, the highest SPAD index was observed in the treatment with 100% chemical fertilizer and 100% edible fungus residue, while the highest photosynthetic rate of flag leaf was in the treatment with 100% chemical fertilizer and 50% edible fungus residue. In addition, the highest grain yield was found in treatment with 100% chemical fertilizer and 100% edible fungus residue. As a result, application of edible fungus residue in combination with chemical fertilizers could improve the leaf photosynthesis of rice during grain filling period, at the same time the grain yield was also increased.
