[Method] Based on lower-graded phos- phate resource, effects of FCMP compound fertilizers on yield and growth of early rice in a field were researched. [Result] FCMP compound fertilizers 0, 1 and 2 en- hanced rice yield, increasing by 21.86%, 20.25% and 13.46%, compared with the rice applied with conventional fertilizer; number of productive ears and grain number per ear in unit area were improved by FCMP compound fertilizer, for example, the two factors achieved the highest with FCMP compound fertilizer 1, increasing by 11.70% and 19.63%. Furthermore, FCMP compound fertilizer promoted plant height and tiller number, maintained high photosynthetic efficiency, enhanced lodging-resis- tance and guaranteed stable and high yield. [Conclusion] The research is of theoret- ical and practical significance for further exploration of production techniques and application of FCMP compound fertilizer.展开更多

Therefore, a bibliometric research was carried out on weak signals and correlated matters between 1980 and 2010 and was supported by the literature review about the subject. The suggested analysis contributes to greater academic knowledge on productivity in the field, providing a broad perspective for future researchers who catch sight of this subject as a potential for further studies.展开更多
