The Effect of Acid Fertilizer FeSO4 on the Growth of Eight Immortals Plant
In order to solve the problem of limited variety and color of summer and autumn flowers in the gardens of Urumqi City,the summer flower Baxian Flower,which has the advantages of long flowering period,diverse flower types and colors,was selected as the experimental ma-terial.Three different concentrations of acidic fertilizer FeSO4 solution were used for treatment.After 60 days,the various indicators of the test material were measured and the mean values of each group were compared.The results showed that the treatment with acidic fertilizer FeSO4 had a positive promoting effect on the growth of potted endless summer plants,and the relevant indicators were better than the control group.Chlorophyll expression was 400 mg/L FeSO4＞200 mg/L FeSO4＞CK,with an average of 47.371,38.951 and 31.635 mg/cm2.Leaf area was 400 mg/L FeSO4＞200 mg/L FeSO4＞CK,with an average of 45.28,34.56 and 19.93 cm2.Plant height was 400 mg/L FeSO4＞200 mg/L Fe-SO4＞CK,with an average of 27.64,19.56,and 11.84 cm.Leaf volume was 400 mg/L FeSO4＞200 mg/L FeSO4＞CK,with an average of 55.07,39.40,and 27.20.Therefore,in the Urumqi region,it is more suitable to use 400 mg/L FeSO4 every 7 days for irrigation treatment of endless summer in agricultural production.
