Effect of Polyglutamic Acid Fertilizer Synergist on Growth Yields and Quality of Solar Cucumber
In order to test the application effects of polyglutamic acid fertilizer synergists on cucumber cultivation,a field experiment was conducted and the effects of different doses of the polyglutamic acid fertilizer synergist on growth,yields and quality of cucumber in greenhouse were analyzed.The results showed that the application of polyglutamic acid fertilizer synergist greatly improved the plant height,internode length,leaf number and dry weight of the root.Compared with the control,the different doses of polyglutamic acid fer-tilizer synergist(T2,T3 and T4 treatments)increased the plant height by 23.5%-39.6%and 11.3%-12.1%at the florescent stage and at the fruit stage,respectively.They also improved the internode length by 21.64%,8.38%,31.58%at the florescent stage and by 3.03%,6.74%,7.98%at the fruit stage,respectively.The different doses of polyglutamic acid fertilizer synergist improved the leaf number by 20.24%,19.05%,14.29%at the florescent stage and by 5.12%,5.12%,3.15%at the fruit stage,respectively,and in-creased the dry weight of the root by 28.57%,92.86%,32.14%at the florescent stage.The application of polyglutamic acid fertilizer synergist increased the yield signficantly.Compared with the control,the single fruit weight was increased by 4.01%-25.84%,and the yield was increased by 1.31%-9.12%.In addition,the application of polyglutamic acid fertilizer synergist also greatly improved the VC content and soluble sugar content,thereby improved the quality of cucumber.In conclusion,when the doses of polyglutamic acid fertil-izer synergist was 9.375 kg·hm-2,the cucumber had high yield and excellent quality.Thus,the polyglutamic acid fertilizer synergist of 9.375 kg·hm-2 could be used as the recommended application dose.
