蔬菜漂浮式育苗,是目前正在试验推广的一种较为先进的育苗技术。与传统育苗方法相比,漂浮式育苗具有技术简单,操作规范,可控性强,无杂草与土传性病害,且出苗整齐一致,生长健壮,栽植成活率高等优势。但在春季育苗时,池水(营养液)中、育苗基质表面有时会滋生青苔。特别是连续阴雨天气,棚内湿度持续偏高情况下,此现象更为严重,轻者影响幼苗萌芽生长,严重者导致黄化、死苗。
Floating nursery vegetables, is currently being tested to promote a more advanced nursery technology. Compared with the traditional seedling raising methods, the floating seedling has the advantages of simple technique, standardized operation, strong controllability, no weeds and soil-borne diseases, and emergence of uniform neatness, robust growth and high survival rate of planting. However, in the spring nursery, pool water (nutrient solution), nursery substrate surface sometimes breeding moss. Especially continuous rainy weather, shed humidity continues to be high, the phenomenon is more serious, the light affect seedling sprouting growth, serious cases lead to yellow, dead seedlings.
