保护地番茄生产多采用苗床育苗栽植方式。在冬春育苗期,常会遭遇寒潮、降雪、重霜、阴雨等“冷阴湿”恶劣生境,在“把式”管理手法失误下,幼苗衰弱,常会形成病苗、死苗,严重时成片枯死至全苗床毁种。为此培育无病壮苗,抓好栽培管理和做好苗病防治是保护地番茄生产的首要条件。 To protect the tomato production more seedbed nursery planting methods. In the winter and spring nursery period, often encounter cold, snow, heavy cream, rain and other “cold and damp” bad habitats, in the “mistakes” management practices mistakes, seedlings weak, often form disease vaccine, dead seedlings, Withered to the seedbed destroyed species. To cultivate disease-free seedlings for this purpose, do a good job of cultivation and management of seedlings and prevent disease prevention and control is the primary condition of tomato production.
