花椒的采后管理直接影响树体的营养积累,花芽分化和来年的开花结果。因此,花椒采后: 1.保护叶片。首先要防治锈病和褐斑病,9月中旬喷一次70％甲基托布津可湿性粉剂300～100倍液,或者25％粉锈宁可湿性粉剂600～800倍液。另外,可给叶面喷施0.1～0.3％的尿素溶液或0.1～0.3％硫酸亚铁溶液,以增强叶片的光合性能,生产和积累更多的碳水化合物和有机态氮。 Postharvest management of Zanthoxylum bungeanum directly affects the accumulation of nutrients in the tree, flower bud differentiation and flowering in the coming year. Therefore, pepper harvest: 1. Protect the leaves. First of all, to prevent rust and brown spot disease, mid-September spray a 70% thiophanate-methyl WP 300 to 100 times, or 25% of the triadimefon WP 600 to 800 times. In addition, 0.1-0.3% urea solution or 0.1-0.3% ferrous sulfate solution can be sprayed on the foliage to enhance the photosynthetic performance of leaves and to produce and accumulate more carbohydrates and organic nitrogen.
