雞冠花的這種現(xiàn)象是由絲核菌屬的一種真菌侵染引起的，稱為雞冠花立枯病。病菌侵染幼苗根頸部，開始時(shí)表現(xiàn)為黑褐色，變軟，后期植株頂部呈現(xiàn)凋萎狀，最后整株枯死。病菌也可侵入莖部和葉片。雞冠花立枯病的病原真菌多存在于土壤和病殘植物體上，可以存活2～3年。在盆土過濕、擺放擁擠、栽植過密、通風(fēng)不良時(shí)，幼苗生長纖細(xì)，這時(shí)完成一個(gè)病程只需3～6小時(shí)。病菌從傷口或表皮直接侵入，在幼苗期能連續(xù)多次發(fā)病。在幼苗出土15天內(nèi)，灌水1次，病害就會(huì)大量發(fā)生。6月下旬至7月間，天氣高溫多濕，是病害的盛發(fā)期。防治雞冠花立枯病的措施：一是加強(qiáng)栽培管理措施，控制盆土濕度，保持適當(dāng)盆距。室內(nèi)栽培應(yīng)注意o匿風(fēng)透光，日常澆水要避免淋濺。地栽雞冠花應(yīng)實(shí)行輪作，避免連栽。幼苗出土15～20天左右，嚴(yán)格控制用水，若必須用水，應(yīng)噴灑到苗濕即可。二是栽植前用1％福爾馬林土壤消毒，有利防病。三是發(fā) 病初期，用45％代森按水劑300～500倍液或70％甲基托布津可濕性粉劑800倍液澆灌，可滅菌保苗。<br> <div class="gwlvfpk" id="contentb"></div> </div> <div id="gwlvfpk" class="clearfix"></div> </div> <div>上一個(gè)：<a
