摘要
为了掌握野稷的生物学性状及生长规律,以利于对其进行科学防控,在吉林省东、中、西部对野稷进行定点观测和调查。结果表明,吉林省农田中的野稷出土高峰期在6月上旬,分蘖高峰期在7月中旬,7月中下旬开始抽穗,花序呈黄色,8月下旬籽粒开始成熟,其中靠近穗顶端的先成熟,随即脱落。种子千粒重为3.7~4.3 g。野稷密度较大的田块,害虫危害有加重的趋势。
The biological characteristics and growth of Panicum miliaceum L.var.ruderale were studied at fixed points in the eastern,middle and western farmland areas of Jilin Province.The peak of emergence occurred in the first ten-day period of June,the peak of tillering was in the middle ten-day period of July.Plants began heading and inflorescence turned yellow in the last ten-day period of July;grain began to mature in the last ten-day period of August,with grains near the top of panicle maturing first and shattering.The 1000-seed weight ranged from 3.7 g to 4.3 g.Fields infested by P.miliaceum L.var.ruderale at high density the harm of pests were negatively affected.
