摘要
Abstract
To investigate different nutrients' impacts on the growth and photosystem of bunching onion,we set up case-control experiment in greenhouse with different concentration of Hoagland solution and defects of N,P and K to determine what kinds of effects impose on bunching onion root growth.Our results indicate that heights and biomass of bunching onion are positively correlated with the concentration of Hoagland solution in certain range.Moreover,increasing concentration levels of Hoagland solution also positively impacted on photosystem,such as performance index (PI),maximum quantum yield for PSII photochemistry,specific energy fluxes and quantum transportation index.Meanwhile,the defection experiment of N,P,and K shows that N defection impacts most seriously on root growth,followed by P and K defection.In terms of improving yields,full component Hoagland solution is the best optimal for practice production.关键词
