摘要
为了研究腐植酸复合肥对"爱媛 38 号"产量、品质、经济效益和土壤理化性质的影响.通过小区试验,设置常规量腐植酸复合肥(T1)、减量 10%腐植酸复合肥(T2)、常规量普通复合肥(T3)3 个处理.结果表明:与普通复合肥相比,减量 10%或常规量腐植酸复合肥处理下"爱媛 38 号"的产量、品质、经济效益、土壤理化性质均有不同程度的改善和提高,其中单株产量增产率为5.38%～8.57%,亩增产率为1.63%～8.66%,可食率、固酸比等口感、风味有明显的改善,产投比达到了6.54～6.76∶1,经济效益显著,且对土壤具有一定的改善作用.
Abstract
Three treatments,i.e.,regular amount of humic acid compound fertilizers(T1),90%amount of humic acid compound fertilizers(T2),and regular amount of ordinary compound fertilizers(T3),were set up during the plot test,and the effects of humic acid compound fertilizers on the yield,fruit quality,economic benefits and soil physical and chemical properties of"Ehime No.38"citrus hybrids were studied.The results showed that,compared to ordinary compound fertilizers,the yield,quality,economic benefits of"Ehime No.38"citrus hybrids and the physical and chemical properties of soil had been improved with different degrees when 90%amount or regular amount humic acid compound fertilizers were applied.Among them,individual plants the yield increase rate was 5.38%～8.57%,the yield increase rate per mu was 1.63%～8.66%,the edible rate,solid-acid ratio and other taste and flavor had been significantly improved,the production-investment ratio had reached 6.54～6.76∶1,and the economic benefits are significant,and had a certain improvement effect on the soil.
