旱育秧移栽后有明显的分蘖和生长优势，尤其在节水灌溉或低土壤水分条件下，旱育秧有效穗数多、干物质累积量高、抽穗后的光合势大，较水育秧显著增产。但在土壤水分充足或常规灌溉条件下，旱育秧分蘖成穗率低、有效穗数少，较水育秧增产幅度小。表明旱育秧配合本田期节水灌溉，其增产潜力较大。 Especially after water-saving irrigation or low soil moisture, the effective spikes of dry-seedlings were higher, the dry matter accumulation was higher, the photosynthetic potential after heading was higher, and the yield was significantly higher than that of water-bearing seedlings . However, under sufficient soil water or conventional irrigation conditions, the tillering rate of tillers in dry nursery seedlings was low, the effective spike number was less and the yield increase was smaller than that of water-saving seedlings. It shows that drought-tolerant seedlings with Honda period water-saving irrigation, the yield potential greater.
