Abstract

In order to prevent the fertility obstacle and increase the yields and fruit qualities of tomato under weak light condition in the facilities,ten formulas which calcium was the main element had been developed and screened.After the first flower of the first inflorescence blossoming,use nature light and weak light(164.05~453.14 μmol·s-1·m-2) as controls,spray distilled water to the all plants in nature light intensity and part of plants in weak light intensity.The others in weak light intensity were treated with ten calcium formulas.Results showed that each group of calcium element formula treatment could significantly reduce the adult plant's length,increase the stem diameter,raise the chlorophyll content and Pn of leaves,increase the yields and fruit quality of tomato under weak light condition.Above all the formulaⅤ,Ⅷ,Ⅹ have better effect on regulating tomato tolerance to bear the weak light stress.
