确保全苗,早培早发,促使棉苗健壮生长,是棉花早熟高产的基础。但本地区这一时期往往多阴雨低温,棉苗易遭立枯病、炭疽病等病菌和地老虎、蓟马、蜗牛、蚜虫、红蜘蛛及象鼻虫的为害。有的年份,在施用未充分腐熟基肥的棉田里,如果播种质量较差,棉籽出土慢,还会遭到种蝇为害,造成大批烂种。无论那一种病虫为害,都会影响棉苗正常生长,轻则生长迟缓,棉苗不匀不壮,
To ensure that all seedlings, early morning training early, prompting the robust growth of cotton seedlings, cotton is the basis for early yield. However, in this period of the region, there are often more rain and cold temperatures. Cotton seedlings are easily affected by diseases such as damping-off and anthracnose, and tigers, thrips, snails, aphids, spider mites and weevils.
