摘　　要：为强壮发病杨梅树势,改良果实品质,选择3种有机肥,设置5、10、20 kg/株共3个施肥梯度,以不施肥作对照,利用滴水线沟施方法施入盛果期病树。结果表明,所有有机肥处理均增加了维生素C含量,增加了2.5%~109.6%,可溶性固形物含量增加1.2%~15.3%,显著降低了可滴定酸含量,降低1.3%~34.2%。复合微生物肥和(深圳)好阳光有机肥均显著增加了梢长,分别增加13.3%~15.4%和22.1%~34.7%,梢粗分别增加5.2%~12.5%和5.2%~19.4%,叶长分别增加10.3%~11.8%和1.4%~5.7%,叶宽分别增加8.0%~14.6%和1.7%~10.5%。另外复合微生物肥3个处理还显著增加单果重6.0%~8.0%,显著降低果实硬度4.1%~9.6%。表明有机肥对杨梅衰弱病树营养生长及果实品质改良有积极的作用,其中复合微生物肥的效果更好,值得在产业上推广应用。In order to strengthen the vigor of decline diseased Myrica rubra trees and improve the fruit quality,three kinds of organic fertilizers were selected,and three fertilizer gradients of 5,10 and 20 kg per plant were set.The diseased trees were applied with drip line furrow application method with no fertilizer as control.The results showed that the content of vitamin C increased by 2.5%-109.6%,the content of soluble solid increased by 1.3%-15.3%,and the content of titratable acid decreased by 1.3%-34.2%.Both compound microbial fertilizer and(Shenzhen)Haoyangguang organic fertilizer significantly increased shoot length by 13.3%-15.4%and 22.1%-34.7%,shoot diameter by 5.2%-12.5%and 5.2%-19.4%,leaf length by 10.3%-11.8%and 1.4%-5.7%,leaf width by 8.0%-14.6%and 1.7%-10.5%,respectively.In addition,the three treatments significantly increased the single fruit weight by 6.0%-8.0%,and significantly decreased the fruit hardness by 4.1%-9.6%.The results showed that organic fertilizer had a positive effect on the vegetative growth and fruit quality improvement of diseased bayberry trees,and the effect of compound microbial fertilizer was better,which was worthy of promotion in industry.
