The field experiment and pot experiment was conducted during 2005–2006 to study the seedling standing characteristics and technology of no-tillage cast transplanting rice. The results showed that no-tillage seedling broadcasting cultivation was beneficial to root growth, seedling standing early and fast, and shoot growth under the conditions of appropriate low water layer (around 1 cm), using younger seedlings, increasing appropriate N at the early growth stage, appropriate straw incorporation (1 200 kg ha-1), dry land seedling raising on plastic trays and spraying paclobutrazol at 2.5 leaf and soaking seed by α-naphthylacetic acid. The standing speed of non erect seedlings had great relation to seedling age, short seedling age quickened seedling standing and promoted rice growth. There were close correlations between average root number and root length per plant, soluble sugar, total N content ofshoot and seedling standing after broadcasting seedlings with no-tillage. The results provided a reference for popularizing and applying the technology of no-tillage and cast transplanting rice in the future.
