A scveening trial of different substrates with industrial rice seedlings cultivation

In this paper, a substrate-screening trial for industrial rice seedlings cultivation was carried out in order to find out good industrial rice seedlings-raising methods and then improve degree of mechanization in rice production. The results showed that highest quality of seedlings was obtained using normal soil in rice field and chemical fertilizer as substrate while lowest cost was obtained using fine soil in rice field and chemical fertilizer as substrate.
