我現種植有1畝大蔥和香蔥，但生長緩慢，行家的45天已上市，我的50天還無法上市，請問您有什麼關鍵技術嗎？謝謝！！

　　若ruo品pin種zhong是shi一yi樣yang
，可ke對dui照zhao幾ji個ge栽zai培pei細xi節jie，了le解jie原yuan因yin，以yi備bei來lai年nian。一yi是shi催cui芽ya播bo種zhong。大da蔥cong種zhong子zi較jiao小xiao，種zhong皮pi厚hou，吸xi水shui力li弱ruo
，出chu土tu較jiao慢man，出chu土tu後hou幼you苗miao生sheng長chang緩huan慢man
，育yu苗miao期qi較jiao長chang。在zai生sheng產chan上shang大da多duo采cai用yong種zhong子zi消xiao毒du，浸jin種zhong催cui芽ya
