趸秧是目前我们这里早稻育秧的主要方式。其优点是能育中苗壮秧,秧龄弹性较无土秧大,同时也能适时早播早插,有利早活早发夺高产。但是,趸秧也还存在着不同程度的烂芽死苗问题。同时也正由于成品率低,大田的用种量大,亩用种一般达60斤左右,种子浪费多。在育秧环节上如何夺取高产优质低成本,这是需要解决的一个重要技术问题。 Single seedling is the main method of early rice growing here. Its advantage is to nurture young seedling seedlings, seedling age more flexible than soilless seedlings, but also timely early planting early, favorable early early hair wins high yield. However, the bulk seedlings also exist varying degrees of rotten buds die. At the same time, it is also due to the low yield, Daejeon with a large amount of species generally used up to 60 acres of seed, the seeds of waste. How to seize high yield, high quality and low cost in the process of raising seedlings is an important technical problem to be solved.
