摘要
为研究化肥减量条件下配施不同有机肥对油麦菜生长、品质及土壤理化性质的影响,本试验应用田间小区试验方法,设置4个施肥处理:单施化肥(T1)、减量20%化肥+氨基酸生物有机肥(T2)、减量20%化肥+鸡粪(含花生枯腐植酸)(T3)、减量20%化肥+炭基肥(T4),其中以单施化肥(T1)为对照。结果表明:(1)T2处理对油麦菜的增产效果最好,较T1可显著增产55.10%,同时其长势也最好,其叶片长达40.03 cm、叶宽为5.10 cm,单株叶片数有21片及SPAD值为29.34,在各施肥处理中均表现最优,此外,T2的安全性最好,亚硝酸盐含量较T1显著降低了50.24%;(2)T3处理对改善土壤结构及提升土壤肥力的效果最好,可降低土壤容重及增加土壤有机质含量,其增加的土壤有机质含量较T1提高了10.67%,但平均隶属度结果显示T2的隶属度值最高。因此,从油麦菜增产提质和土壤改良这2个方面综合考虑,建议油麦菜种植采用化肥减量配施氨基酸生物有机肥的施肥方式。
In order to study the effects of combined application of different organic fertilizers on the growth,quality and soil physicochemical properties of Lettuce under the condition of chemical fertilizer reduction,the field plot test method was used to set up four fertilization treatments including single application of chemical fertilizer(T1),reduction of 20%chemical fertilizer+amino acid bio organic fertilizer(T2),reduction of 20%chemical fertilizer+chicken manure(including peanut dry humic acid)(T3),reduction of 20%chemical fertilizer+carbon based fertilizer(T4).The single application of chemical fertilizer was used as the control.The results showed that:(1)T2 had the best yield increase effect,which was 55.10%significantly higher than that of T1,and its leaf length(40.03 cm),leaf width(5.10 cm),number of leaves per plant(21 leaves)and soil and plant analyzer development(SPAD,29.34)were the best in all fertilization treatments.In addition,T2 had the best security,which could significantly reduce the nitrite content by 50.24%compared with T1.(2)T3 had the best effect on improving soil structure and soil fertility.It could reduce soil bulk density and increase soil organic matter.Compared with T1,T3 significantly increased soil organic matter by 10.67%,but the average membership result showed that T2 has the highest membership value.Therefore,considering the increase of yield and quality of Lettuce and soil improvement,it is suggested to adopt the fertilization method of reducing chemical fertilizer combined with amino acid bio-organic fertilizer.
