不同叶面肥喷施对甜玉米生长及经济效益的影响

Effects of Different Foliar Fertilizers on Growth and Economic Benefits of Sweet Corn

为研究不同叶面肥喷施对甜玉米生长及产量的影响,开展田间试验,共设置4个处理,分别为:空白处理(T1)、常规施肥处理(T2)、常规施肥处理+EM菌剂(T3)和常规施肥处理+氨基酸叶面肥(T4).试验结果表明,喷施EM菌剂的T3处理小区产量最高,达14.92 kg,较T1、T2和T4处理分别显著增加33.53%、19.82%和18.12%;T3和T4处理甜玉米单果质量较T2处理分别增加了4.45%和1.21%,但三者间不存在显著性差异;T3处理甜玉米株高最高,显著高于CK处理;T3处理的茎粗比T2和T4处理分别增加了12.86%和2.32%.通过经济效益分析可知,T3处理的利润最高,T4处理次之,667 m2利润分别为5634.06、4555.44元,分别比T1处理增加1665.40、586.78元.以上结果表明,EM菌剂和氨基酸叶面肥的施用,可以明显促进甜玉米的生长及产量的增加,且EM菌剂对甜玉米的促进效果要好于氨基酸叶面肥.

In order to study the effects of different foliar fertilizers on the growth and yield of sweet corn,the fieldexperiment was carried out by setting four treatments,the control treatment(T1),conventional fertilization treatment(T2),conventional fertilization+EM bacterial spraying treatment(T3)and conventional fertilization+amino acid foliar fertilizer spraying treatment(T4).The results showed that the highest yield of sweet corn was 14.92 kg/plot in T3 treatment,which was significantly higher than those in T1,T2 and T4 treatments,with the increasing rates of 33.53%,19.82%and 18.12%.The single fruit weight in T3 and T4 treatments were 4.45%and 1.21%higher than that in T2 treatment,but there was no significant difference among them.The plant height of sweet corn in T3 treatment was the highest,which was significantly higher than that in T1 treatment.The stem diameter in T3 treatment was 12.86%and 2.32%higher than that in T2 and T4 treatments respectively.The results of economic benefit analysis showed that,T3 treatment had the highest economic benefit,followed by T4 treatment,and the economic benefits of T3 and T4 were5634.06,4555.44 Yuan/667 m2,which were1665.40,586.78 Yuan/667 m2 higher than that of T1 treatment.Inconclusion,the application of EM fungicide and amino acid foliar fertilizer could significantly promote the yield and growth indexes of sweet corn,and the effects of EM fungicide was better than that of amino acid foliar fertilizer.
