Abstract: Effects of seed coating fertilizer on seedling growth and biochemic indicator of direct-seeded early rice were firstly studied by means of experiment of field direct-seeding with rice seed coated by seed coating fertilizer. The results show that the seedling growth and the indicators of biochemistry of the rice seed was coated by seed coating fertilizer with the coating rate of 1:50, 1:70, 1:90 were superior to those of CK, except germination rate is slightly lower. The seedling rate, seedling height, number of total roots, number of white roots, dry weight, unit dry weight, root activity, free proline content and Chlorophy ll content of coated seed with the coating rate of 1:70, increased by 8.4%, 2.1%, 18.8%, 4.4%, 19.3%, 10.8%, 44.9%, 32.9%, 14.6% compared with CK, respectively, which were better than those of the other coating rates.
