控释复合肥对麦套花生光系统II性能及产量和品质的调控效应
Effect of Controlled-release Compound Fertilized on Photosystem II Perfor-mance, Yield and Quality of Intercropped Peanut with Wheat
摘要
Abstract
Peanut variety 606 was used to investigate photosynthetic characteristics, yield and quality of intercropped peanut with wheat, and to explore the mechanism of physiological responses of photosystem II to controlled-released compound fertilizer, which was 35% for base fertilizer, 35% applied at jointing stage and 30% applied at initial flower stage. The leaf area index (LAR), chlorophyll content (Chl) and net photosynthetic rate (Pn) were gradually reduced at the late growth stage of peanut. Application of the controlled-released compound fertilizer increased Chl, decreased LAR and Pn, compared with that of common compound fertilizer. In JIP-test analyzing, the OJIP fluorescence induction curve was affected significantly by fertilization, and the fluorescence intensity of K, J, and I steps was significantly decreased. The probability of a trapped exciton moving an electron into the electron transport chain beyond QA(Ψo) and the performance index on absorption basis (PIabs) were significantly increased under applying controlled-released compound fertilization, while the relative variable fluorescence intensity at the K-step (Wk) and at the J-step (Vj) was reduced. The comprehensive performance of electron transport chain in PSII reaction center and the electron transport capacity both in the donor side and the receptor side were increased obviously, and the performance of the re-ceptor side was greater than that of the donor side. Applying controlled-release compound fertilizers increased the pod yield and kernel yield by 11.3% and 15.2% respectively as compared with those of applying common compound fertilizers. While the con-trolled-released compound fertilizer treatment also increased the contents of protein, fat and soluble sugar in kernel, and increased the O/L ratio significantly. Therefore, Under the same application rates of N-P2O5-K2O, applying the controlled-released com-pound fertilizer can significantly improve the photosynthetic performance for improving yield and quality of peanut compared with applying the common compound fertilizer.关键词
