五月中旬,由北京农业大学和柏各庄农垦区牵头,在柏各庄农垦区召开了脲醛泡沫水稻育秧实验的现场汇报会。脲醛泡沫育秧,是国外近年来正在研究、推广的一种工厂化育秧的新方法。应用这种方法,可以育出适合于机械插秧的壮秧。单产与秧田薄膜育秧和工厂化有土育秧不相上下。脲醛泡沫育秧既比薄膜育秧具有大幅度节省种子、水、肥、工、秧田和更适于机械插秧的优点,又可避免工厂化有土育秧需用大量客土和耗用大量工业硫酸调节pH值的大难题和克服工厂化无土育秧只能育小苗而难
In mid-May, led by Beijing Agricultural University and Baigezhuang Reclamation Area, a field briefing on urea-formaldehyde foam rice seedling cultivation experiments was held in Baigezhuang Reclamation Area. Urea-formaldehyde foam seedlings, foreign countries in recent years are being studied to promote a new method of plant seedlings. Apply this method, you can breed strong seedlings suitable for mechanical transplanting. Yield and seedling film seedlings and factory farming soil comparable. Urea-formaldehyde foam seedling not only has the advantages of seed, water, fertilizer, labor, seedling and more suitable for mechanical transplanting than film seedling, but also avoids the need of using a large amount of soil for industrialized soil-based seedling and consuming large amount of industrial sulfuric acid to adjust pH The value of the big problems and overcome the factory of soilless seedlings can only nurture seedlings and difficult
