酸性肥料FeSO_(4)对八仙花植株生长的影响

The Effect of Acid Fertilizer FeSO_(4) on the Growth of Eight Immortals Plant

为解决乌鲁木齐市园林中存在的夏秋季花种类少和花色缺乏的问题,选用花期长、花型和颜色多样性的夏季花卉八仙花作为试验材料,采用3种不同浓度的酸性肥料FeSO_(4)溶液进行处理。60 d后,对试验材料的各项指标进行测定。结果表明,酸性肥料FeSO_(4)处理对于盆栽无尽夏的植株生长起到了积极的促进作用,相关指标均优于对照组。叶绿素表现为400 mg/L>200 mg/L>CK,均值为47.371、38.951、31.635 mg/cm^(2),叶面积表现为400 mg/L FeSO_(4)>200 mg/L FeSO_(4)>CK,均值为45.28、34.56、19.93 cm^(2),株高表现为400 mg/L FeSO_(4)>200 mg/L FeSO_(4)>CK,均值为27.64、19.56、11.84 cm,叶量表现为400 mg/L FeSO_(4)>200 mg/L FeSO_(4)>CK,均值为55.07、39.40、27.20。因此,在乌鲁木齐地区,农业生产上使用400 mg/L FeSO_(4)每隔7 d进行一次FeSO_(4)的浇灌处理无尽夏较为合适。

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 material.Three different concentrations of acidic fertilizer FeSO_(4) 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 FeSO_(4) 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 FeSO_(4)>200 mg/L FeSO_(4)>CK,with an average of 47.371,38.951 and 31.635 mg/cm^(2).Leaf area was 400 mg/L FeSO_(4)>200 mg/L FeSO_(4)>CK,with an average of 45.28,34.56 and 19.93 cm^(2).Plant height was 400 mg/L FeSO_(4)>200 mg/L FeSO_(4)>CK,with an average of 27.64,19.56,and 11.84 cm.Leaf volume was 400 mg/L FeSO_(4)>200 mg/L FeSO_(4)>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 FeSO_(4) every 7 days for irrigation treatment of endless summer in agricultural production.
