育苗是蔬菜栽培上的一个重要环节。通过育苗,可以缩短作物在大田的生育期,提高土地利用率,降低生产成本,提高产量品质。哈市茄果类蔬菜育苗期较长,需80~120天,且苗期温度由高到低,在育苗过程中常易发生猝倒病、立枯病等侵染性病害及各种生理障碍,如徒长苗、僵苗、冻害苗和幼苗烧根、沤根及各种气害,从而影响秧苗的正常生长。本文主要介绍了几种茄子苗期病害及生理障碍的识别与防治方法。
Seedling is an important link on vegetable cultivation.Through breeding,can shorten the growth period of crops in the field,improve the land utilization rate,reduce production cost,improve the yield and quality.Harbin solanaceous vegetable seedling period,80~120days,and from high to low temperature at seedling stage,often in the breeding process,such as Rhizoctonia Damping off disease occurrence of infectious disease,and various physiological disorders,such as Stunty, leggy seedlings,seedling and seedling frost burn the root,root and all kinds of gas.Harm,thus affecting the normal growth of seedlings.
