甜菜纸筒育苗移植栽培技术,对改革传统栽培、提高产量、促进生产的发展有巨大的推动作用。通过试验示范,我们认为这项技术简单易行,深受农民欢迎。 1.育苗时间。育苗过早气温低,苗期过长,苗弱影响移栽成活率,过晚则苗期短,苗小起不到育苗增温延长生育期的效果。育苗时间一般为3月20—25日,最迟不过3月末。保证增加积温300℃以上,满足甜菜生育时期170—180天的需要。
Beetle tube seedling transplant cultivation techniques, the reform of traditional cultivation, increase production, promote the development of production has a huge role in promoting. Through experiment and demonstration, we think this technology is simple and easy and popular among peasants. 1. Nursery time. Premature nursery temperature is low, the seedling is too long, weak seedlings affect the survival rate of transplanting, too late, the seedling is short, young seedlings less than the effect of raising temperature to increase growth period. Nursery time is generally March 20-25, the latest but by the end of March. Guaranteed to increase the accumulated temperature above 300 ℃, to meet the needs of beet breeding period of 170-180 days.
