不管是盆栽还是地栽的杜鹃,在生长过程中都存在着这样的缺点:开花不均,花形不齐整,花期不一,不可调节。经过多年栽培试验,笔者终于初步弄清温度、日照,特别是生长抑制物质和促进物质对杜鹃生长、开花的影响。经过处理,便可减轻这些影响。花后处理:杜鹃花后,经过简单的摘心和修剪,可形成理想的株形,施2～3次薄肥,可补足开花的营养消耗。当新梢枝条生长30天以上时,可用矮壮素处理新枝。我们是用多效唑1000倍液喷施叶面,一周1次,喷2～3次,多花的品种要用4次。这样可以抑制新梢生长,积累同化物质,促进下次花芽形成,使株型紧
Whether potted or planted rhododendron, in the growth process there are such shortcomings: uneven flowering, flower shape is not the same, the flowering of different, can not be adjusted. After years of cultivation experiments, I finally figure out the initial temperature, sunshine, especially growth inhibiting substances and promoting substances on the cuckoo growth and flowering. After treatment, these effects can be alleviated. After treatment: Azalea, after a simple topping and pruning, can form the ideal plant shape, applied 2 to 3 times thin fat, can make up the flowering nutrition consumption. When the shoot shoots grow more than 30 days, the new branch can be treated with chlormequat. We are using paclobutrazol 1000 foliar spray foliar, 1 times a week, spray 2 or 3 times, spend more varieties to use 4 times. This can inhibit the growth of shoots, accumulation of assimilation substances, and promote the formation of the next flower buds, so strain tight
