植物生长调节剂引起的药害: 水稻苗床使用壮秧剂(壮秧剂含多效唑或烯效唑)、生根粉(含吲哚丁酸+萘乙酸)、生根宝、生根灵、云大120、叶霸、移栽乐(有效成分是稻瘟灵+恶霉灵十2,4-D)等。壮秧剂里含多效唑或烯效唑的量很少,在加工过程中混拌不匀或把壮秧剂作肥料使用,用量过多或混拌不均匀或用壮秧剂后再用生根粉、生根宝、生根灵等,植物生长剂总量过大,造成水稻发生药害。杀菌剂移栽乐用量过高或使用壮秧剂后再用移栽乐,也有用移栽乐后再用生根粉、生根宝、云犬120、生根灵等,多次重复使用人工合成的植物生长调节剂,都能造成水稻药害。幼苗受药害后表现为叶色浓绿、叶宽、叶片向下弯或徒长。稻苗茎略粗,地下不长新根、根少,貌似壮苗。一般
Phytoremediation caused by plant growth regulators: rice seedling used strong seedling agent (seedling enhancer containing paclobutrazol or uniconazole), rooting powder (containing indole butyric acid + naphthalene acetic acid), rooting, rooting, YunDa 120, Ye Pa, transplanting music (the active ingredient is rice Blast spirit + hymexazol 12-D) and so on. Seedling agent containing paclobutrazol or uniconazole in very small amount, uneven mixing in the processing or strong seedling agent for fertilizer use, excessive dosage or mixing uneven or strong seedling agent and then use rooting powder , Rooting, rooting and so on, the total amount of plant growth agent is too large, resulting in rice phytotoxicity. Fungicides transplanting music overdose or use strong seedling agent and then transplanting music, but also useful transplanting music and then rooting powder, rooting treasure, cloud dog 120, rooting spirit, repeated use of synthetic plants Growth regulators, can cause rice phytotoxicity. Seedlings showed green leaf color, leaf width, curved leaves or leggy. Rice stems slightly thick, the ground is not a long new roots, roots less, seemingly strong seedlings. general
