微生态制剂改良土壤对凋萎病杨梅营养生长和果实品质的作用

Effects of Micro-ecology Preparation Improving Soil on the Vegetative Growth and Fruit Quality of Twig Blight Diseased Bayberry

凋萎病是近年来危害杨梅产业的主要病害,为研究微生态制剂对凋萎病杨梅营养生长和果实品质的影响,设置抗重茬微生态制剂、土壤调理剂、生物有机肥以及不同组合处理进行试验,常规管理为对照。结果表明,各处理均显著促进梢长、梢粗、叶长、叶宽,显著降低果实可滴定酸含量。其中抗重茬微生态制剂处理的梢长、梢粗和叶长分别比对照增加122.92%、19.80%和18.94%,果实可溶性固形物和总糖分别增加9.98%和19.04%,表现最优;生物有机肥处理的叶宽比对照增加15.99%,表现最优。土壤调理剂处理的果实可滴定酸含量比对照降低51.16%,为最低。综上所述,所有处理中单施用抗重茬微生态制剂的杨梅营养生长和果实品质最好,抗重茬微生态制剂值得在杨梅产业上大力推广用于改良凋萎病杨梅的营养生长和果实品质。

Bayberry twig blight has been a major disease endangering the bayberry industry in recent years.In order to study the effect of micro-ecology preparation on the vegetative growth and fruit quality of twig blight diseased bayberry,anti-continuous cropping microbial agent,soil conditioner,bio-organic fertilizer and different combinations were selected for experiments,and conventional management was the control.The results showed that all the treatments significantly promoted shoot length,shoot diameter,leaf length and leaf width,and significantly reduced the titratable acid content of fruits.Compared with those of the control,the twig length,shoot thickness,leaf length,soluble solids and total sugar of anti-continuous cropping microbial agent treatment were the highest,which increased by 122.92%,19.80%,18.94%,9.98%and 19.04%,respectively;the leaf width of bio-organic fertilizer treatment was the highest,increased by 15.99%;the content of titratable acid of soil conditioner treatment was the lowest,decreased by 51.16%.In summary,the vegetative growth and fruit quality of the single application of anti-continuous cropping microbial agent were the best among all the treatments.The anti-continuous cropping microbial agent could be promoted to improve the quality of the vegetative growth and fruit quality of bayberry influenced by twig blight.
