碎米知风草对不同环境因子的适应性及化学防治药剂的筛选OA北大核心CSTPCD
Adaptability of Eragrostis japonica to different environmental factors and screening of herbicides for its control
碎米知风草(Eragrostisjaponica)是稻田恶性禾本科杂草之一.为明确影响碎米知风草种子萌发的主要环境因子,并筛选有效的化学防除药剂,采用培养皿法和盆钵法分别测定了温度、光照、pH、盐胁迫、渗透势、埋土深度对碎米知风草种子萌发的影响,并评价了 27种稻田除草剂对碎米知风草的活性.结果表明,碎米知风草种子在20～40 ℃内均能萌发,恒温条件下最适萌发温度为35 ℃,变温条件下为35 ℃/25 ℃;其种子对光照较为敏感,黑暗条件下无法萌发…查看全部>>
Eragrostis japonica is one of the malignant gramineous weeds in paddy fields.To clarify the main environmental factors affecting the seed germination of E.japonica,the Petri dish and pot methods were conducted to determine the effects of temperature,light,pH,salt stress,osmotic potential,and sowing depth on seed germination.In addition,27 herbicides were evaluated for the control of E.japonica.The results showed that the seeds could germinate at 20～40 ℃.The …查看全部>>
