土壤改良剂对樱桃番茄生长和产量的影响

为研究DK-1土壤改良剂对樱桃番茄生长和产量的影响,设置3个处理,分别为T1:对照(不施用任何肥料);T2:常规施肥处理;T3:DK-1土壤改良剂。定植35 d后测定番茄的生长指标,成熟期分次采摘计产,作物清茬后测定土壤pH值和EC值。试验结果表明,无论是生长指标还是产量T3都显著高于T1、T2(除茎粗、叶绿素含量、pH值差异不显著外),其中T3的产量分别比T2、T1高出8.3%和56.6%;T3的土壤pH值显著高于T1和T2,T3的EC值最低,显著低于T1和T2,比T2低30.5%。说明DK-1土壤改良剂可以改善土壤性状,促进番茄生长,提高番茄产量。

Effects of Soil Amendment on Growth and Yield of Cherry Tomato

Taking cherry tomato as material,the test was carried out to study the effects of DK-1 soil amendment on the growth and yield of cherry tomato.The results showed that the growth indexes and yield of T3 treatment were better than those of T1 treatment(no fertilizer application)and T2 treatment(conventional fertilizer application),and the yield of T3 treatment(conventional fertilizer and DK-1 soil amendment application)was 8.3%and 56.6% higher than those of T2 treatment and T1 treatment,respectively.The pH value of T3 treatment was significantly higher than those of T1 treatment and T2 treatment,and the EC value of T3 treatment was the lowest,which was significantly lower than those of T1 treatment and T2 treatment,moreover,the EC value of T3 treatment was 30.5% lower than that of T2 treatment.In conclusion,DK-1 soil amendment could improve soil properties,promote growth and increase yield of cherry tomato.
