目前，河北衡水棉苗平均高度在20-25cm，已現(xiàn)真葉8片左右，還沒(méi)有再現(xiàn)早期果枝情況。據(jù)當(dāng)?shù)剞r(nóng)民講，去年同期棉花高度在30cm左右，真葉8-10片，而且那時(shí)極少數(shù)棉株已經(jīng)長(zhǎng)出了果枝。今年受前期干旱的影響，今年棉苗長(zhǎng)勢(shì)稍差于往年。另外，當(dāng)?shù)孛尢镉行∫?guī)模蟲情發(fā)生，蚜蟲、紅蜘蛛、一代棉鈴蟲、盲蝽蟓均有不同程度出現(xiàn)。
眼下正值棉苗發(fā)育期，降雨后棉農(nóng)應(yīng)及時(shí)進(jìn)行松土中耕，防止土壤板結(jié)，使土壤疏松層保持疏松，出現(xiàn)蟲害的棉田要加緊噴藥除治，實(shí)現(xiàn)壯苗早發(fā)。
