为了明确可降解秧盘育插秧技术在北方寒地水稻生产中利用的特点及其对水稻产量的影响，黑龙江浓江农场在2016年和2017年以龙粳46和龙粳52为材料，利用可降解钵毯秧盘进行育插秧试验，并以塑料钵毯秧盘育插秧为对照。结果表明，与塑料秧盘育插秧相比，用可降解秧盘育秧可以提高机插秧苗素质，改善机插效果，水稻增产1.7%~3.5%。该技术具有育插秧方便、省工节本、绿色环保、增产增效等特点，适于在黑龙江垦区大面积推广。

In order to ascertain the yield performance and technical characteristics of seedling nursing with degradation tray on machine transplanting rice in cold region, a field test with machine transplanting technology and seedling nursing in degradation pot-flat tray was conducted using Longgeng 46 and Longgeng 52 as materials in 2016 and 2017 at Nongjiang State Farm, in contrast with the plastic pot-flat tray seedling nursing. The results showed that, compared to the plastic pot-flat tray seedling nursing treatment, the rice seedling nursing in degradation tray treatment improved the seedling quality and the effects of rice mechanical transplanting, increased the grain yield by 1.7%~3.5%. Due to the technological advantage of convenience, laborsaving, environment protecting, and efficiency increasing, the mechanical transplanting technology with degradation tray nursing seedling is suitable for extensive application in rice production.
