摘要：

为探明“育苗伴侣”在成都平原稻麦两熟模式下机插秧育秧中的适宜用法与用量，以杂交稻组合德优4727为材料，对不同用量“育苗伴侣”在机插秧育秧中的效果进行了试验。结果表明，在水育旱管育秧模式下，采用30 g/盘的用量，采取与营养土混匀装盘方式，40 d秧龄时，秧苗生长整齐，成苗率高，对叶龄的影响较小，极显著提高秧苗鲜质量、秧苗干质量、充实度、根数、根鲜质量、根干质量，从而使秧苗生长矮健，满足插秧机的作业要求。

Abstract:

In order to explore the appropriate usage and dosage of seedling cultivation mate in the context of rice-wheat double-cropping system in Chengdu Plain, a test of different consumption on machine transplanting seedlings were studied, with hybrid rice combination Deyou 4727 as material. The results showed that seedlings grew well and seedling establishment proved higher on the 40th d of seedling cultivation, with the mode of seedling cultivation in paddy field and dryland management, the seedling cultivation mate was collected on seedling trays at 30 g per tray and mixed with nutrient soils for mechanical transplanting. What's more, such practice well controlled seedling growth and extremely promoted seedlings in terms of fresh weight, dry weight, grain plumpness, the number of root, and fresh/dry weight of root. It can be concluded that seedling cultivation mate is suitable to be applied in mechanical transplanting rice.
