摘要
引进黑龙江省方正县的旱育稀植栽培技术及原正市创导的旱育稀植栽培技术与赤水市近年推广的地膜湿润育秧栽培技术进行育秧方式、栽培密度的比较试验，结果表现出旱育栽培优于湿润育秧。旱育秧抗逆性强，秧苗素质好，分染力强，增产明显，特别是以方正式旱育秧植23．5万窝／ha增产显著。
Comparison trials for 3 rice seedling raising techniques involving the techniques of raising in upland nursery introduced from Fangzhen County, Helongjiang Province,Harada's upland nursery method and the techniques of raising seedling in water saturated nursery. Each trial was cultivated with 3 different densities in 2 continuous years. The results showed that the seedlings raised in upland nursery were better than those in water saturated nursery. Rice seedlings cultivated in upland nursery showed higher resistance to adversity, better quality, high tillering ability, and thus increased yield significantly.The yield with Fang zhen county's method at a density of 255000 seedlings/ha was the highest.
