研究了不同浓度水杨酸壳聚糖复合涂膜对台农1号芒果采后病害的防治效果,结果表明:水杨酸壳聚糖复合涂膜能够延缓芒果后熟进程,延长芒果贮藏时间,效果优于单一的壳聚糖涂膜;水杨酸壳聚糖复合涂膜对炭疽病和蒂腐病均有一定的抑制效果,在水杨酸浓度为0.5～2.0 mmol/L的条件下,随着水杨酸浓度的增加,防治效果越来越明显,其中以2.0 mmol/L水杨酸壳聚糖复合涂膜处理的效果最好,其对炭疽病和蒂腐病的防效分别为42.15%和87.19%,对蒂腐病的防治效果比炭疽病更明显。 The effects of different concentrations of salicylic acid chitosan composite coating on the postharvest diseases of mangosteen in Tai Nong 1 were studied. The results showed that the salicylic acid chitosan composite coating delayed the mango ripening process, prolonged the storage time of mango, The effect is better than a single chitosan coating; salicylic acid chitosan composite coating on anthracnose and pedicle rot have a certain inhibitory effect, salicylic acid concentration of 0.5 ~ 2.0 mmol / L conditions, With the increase of salicylic acid concentration, the control effect became more and more obvious. The treatment with 2.0 mmol / L salicylic acid chitosan composite coating had the best effect and the control effect against anthracnose and pedicel rot were 42.15% and 87.19%, respectively. The control effect on pediculosis was more obvious than anthracnose.
