Abstract:

The objective is to study the effects of organic active nitrogen fertilizer (OAN) on plants growth, yield and quality of rice, and provide supporting technologies of production and application of the fertilizer. ‘Jiayin 2’ was used as the material, 4 fertilizer treatments and one control with no fertilizer were set up. The field plot comparative experiment was conducted. Compared with control and other fertilization treatments, in T2 (OAN combined with phosphate and potash fertilizer) had more effective panicles per plant and high dry matter accumulation at maturity. The yield of T2 was increased by 0.95% compared with that of T1 (urea combined with phosphate and potash fertilizer), by 12.94% compared with T3 (only OAN), and by 9.45% compared with T4 (only urea). Meanwhile, the grain length and gel consistency was improved, while the chalk white rice rate was decreased; the protein, amylase, appearance quality, cooking and taste quality, and nutritional quality were improved. Thus, the organic active nitrogen fertilizer (OAN) should be applied with phosphate and potash fertilizer, which could promote rice plants growth, increase grain yield and improve rice quality.
