施用EM菌发酵有机肥对番茄植株生长·产量和品质的影响

Effects of Organic Fertilizer Fermented by EM on Growth,Yield and Quality of Tomato

以“格雷”番茄品种为材料,研究施用以EM菌发酵的有机肥对番茄植株生长、产量以及品质的影响。结果表明,施用有机肥能促进番茄茎粗的增长,但对番茄株高和叶片数量无显著促进作用。相较于施用常规发酵有机肥的处理,施用以EM菌发酵的有机肥的番茄单果重更大,其单株产量也显著高于施用常规发酵有机肥的处理。相比于CK处理,施用有机肥的4个处理均能显著提高番茄可溶性糖和维生素C含量,同时降低有机酸和硝酸盐含量,而施用以EM菌发酵的有机肥相较于施用常规发酵的有机肥,对提高维生素C含量和降低番茄硝酸盐含量的作用更加显著。综上,施用以EM菌发酵的有机肥种植番茄,可以促进番茄生长,提高番茄产量和品质。

The effects of organic fertilizer fermented by EM(effective microorganisms)on the growth,yield and quality of tomato plants were studied.The results showed that the application of organic fertilizer could promote the growth of stem diameter,but had no significant effect on plant height and leaf number.Compared with the traditional fermentation of organic fertilizer,the treatment of application of organic manure fermented by EM gained a more significant effect on fruit weigh,and the yield was significantly higher than treatment of application organic manure fermented by traditional methods.Compared with CK treatment,the contents of soluble sugar and vitamin C of the treatments applied organic fertilizer were significantly increased,while the contents of organic acids and nitrates were also decreased,significantly.Compared with treatment of application organic manure fermented by traditional methods,the treatment of application of organic manure fermented by EM gained a more significant effect on increasing the content of vitamin C and decreasing the content of nitrate in tomato.In conclusion,the tomato cultivation of application of organic manure fermented by EM,can promote the growth of tomatoes,tomato yield and improve the quality.
