李橋鎮(zhèn)開(kāi)展春季病蟲(chóng)害防治

發(fā)布時(shí)間：2015-03-28 08:32:54 來(lái)源：農(nóng)民日?qǐng)?bào) 作者：佚名責(zé)任編輯：羅伯特

　　京郊順義區(qū)李橋鎮(zhèn)緊鄰首都國(guó)際機(jī)場(chǎng)東側(cè)。作為綠化景觀(guān)重要鄉(xiāng)鎮(zhèn)之一，從3月初開(kāi)始，該鎮(zhèn)就聯(lián)合開(kāi)展了春季防治春尺蠖行動(dòng)，防治面積100余畝。

　　“春尺蠖”，又名楊尺蠖、柳尺蠖、沙棗尺蠖，俗稱(chēng)“吊死鬼”。該蟲(chóng)發(fā)生期早，幼蟲(chóng)發(fā)育速度快，主要危害楊、柳、榆、桑、槐等樹(shù)木，若不及時(shí)采取有效措施，會(huì)嚴(yán)重影響林木正常生長(zhǎng)，甚至誘發(fā)其它病蟲(chóng)害。據(jù)了解，該鎮(zhèn)今年防治林木有害生物3.5萬(wàn)畝，防治方法主要采取黑光燈誘殺及生物天敵防治（大面積放置周氏嚙小蜂），同時(shí)加大對(duì)平原造林工程苗木進(jìn)場(chǎng)的檢疫工作，防止外來(lái)物種的入侵。董大偉李曉山
