化肥减施条件下土壤改良剂及氨基酸叶面肥对水果黄瓜生长和产量的影响

Effects of Soil Amendment and Amino Acid Foliar Fertilizer on Growth and Yield of Mini Cucumber under Condition of Chemical Fertilizer Reduction

在化肥减施条件下,为探究生长调节剂及氨基酸叶面肥对水果黄瓜生长及品质的影响,开展了田间试验,共设置5个处理,T1,空白对照;T2,常规施肥;T3,常规施肥+土壤改良剂;T4,土壤改良剂+20%化肥减施;T5,土壤改良剂+20%化肥减施+氨基酸叶面肥。试验结果表明,在化肥减施的情况下,配施土壤改良剂和氨基酸叶面肥的T5处理可以显著提高水果黄瓜产量和生长指标,水果黄瓜产量、株高、茎粗、叶绿素分别提高了39%、19%、20%、18%,T5处理的经济效益较常规施肥有明显的增加。因此,在化肥减施20%条件下,配施氨基酸叶面肥和土壤改良剂可以有效促进水果黄瓜产量和经济效益的增加。

Under the condition of chemical fertilizer reduction,in order to explore the effects of growth regulator and amino acid foliar fertilizer on mini cucumber growth and quality,the field experiment was carried out.Five treatments were set totally:T1,control treatment;T2,conventional fertilizer treatment;T3,conventional fertilizer treatment+soil amendment;T4,soil amendment+20%chemical fertilizer reduction treatment;T5,soil amendment+20%chemical fertilizer reduction+amino acid foliar fertilizer treatment.The results showed that under the condition of chemical fertilizer reduction,T5 with soil amendment and amino acid foliar fertilizer could dramatically increase yield and growth indexes of mini cucumber.The yield,height,thickness and chlorophyll content were increased by 39%,19%,20%and 18%respectively,and the economic benefit of T5 was much more than that of the conventional fertilizer treatment.Therefore,under the condition of 20%chemical fertilizer reduction,combined application of amino acid foliar fertilizer and soil amendment could effectively promote the increase of yield and economic benefit of mini cucumber.
