依据我区春季寒潮入侵频繁,气温冷暖极不稳定这一特点,近年来各县(市)普遍采用“两段育秧”方式,扼制了因寒流影响造成的烂秧问题。对扩大种植增产潜力较大的中、晚熟品种,实现迟栽早熟,避过低温秋风,夺取高产稳产发挥了重要作用,深受广大粮农的欢迎,但是各地在两段育秧的第一阶段——温室育秧中由于浸种、消毒、催芽、炼苗等技术环节上把关不严、管理不当容易出现烧籽、烧芽、黄苗、弱病苗等问题。如何恰到好处地研究解决上述问题是“两段育秧”技术体系中的一个重要课题。故此,本文作者根据多年的育秧经验和生产调查,对温室育秧中易出现的问题谈点技术对策,以供同行商榷。
According to the frequent influx of spring cold wave in our district, the temperature is extremely unstable in cold and warm. In recent years, counties (cities) generally adopted the “two-stage seedling raising” method to curb the problem of rotting seedlings caused by the cold current. To expand the cultivation of large potential yield increase late maturing varieties, to achieve late-planted early, to avoid low-temperature autumn wind, to seize high and stable yield has played an important role, welcomed by the majority of farmers, but throughout the first two stages of nursery - Greenhouse seedlings in the seed soaking, disinfection, germination, refining and other technical aspects of the link is not strict, improper management prone to burning seeds, burning buds, yellow seedlings, weak seedlings and other issues. How to properly study and solve the above problems is an important issue in the technical system of “two-stage seedling raising”. Therefore, the author of this article based on many years of experience in seedling raising and production survey, the greenhouse seedling prone problems that talk about technical solutions for discussion with counterparts.
