旱育秧技术自1993年引进以来,经过多年的试验、示范、推广,技术比较成熟。但在培肥苗床中,大多施用复混肥,特别是在土壤pH值较高的洲地土壤和老菜园土上往往出现黄苗或死苗。为解决生产上出现的这一新问题,我站从1997年起试验示范市土肥站研制生产在旱秧专用肥——旱秧青,承担了市 Dry-raising seedling technology since its introduction in 1993, after years of testing, demonstration, promotion, technology is more mature. However, in the fertilization seedbed, most of the application of compound fertilizers, especially in the soil pH of the continent soil and old garden soil often appear yellow or dead seedlings. In order to solve this new problem appearing in production, I started to test and test the demonstration city of soil and fertilizer station in 1997 to develop and produce special fertilizer for dry cultivation seedlings,
