Abstract:

The application of green manure dressing with transformation promoter, the ammonium carbonate and the nitrolime used in rice field and the typical paddy soil in south were selected as materials in this study, a plot experiment was conducted to test the effects on the paddy soil fertility and rice output of green manure dressing with different transformation promoter. Results showed that green manure dressing has various advancements, such as: improving available phosphorus, improving soil organic, regulating soil alkaline hydrolysis nitrogen content and promoting fertilizer land productivity. The green manure dressing with transformation promoter was also to speed up the decomposing of soil organic. The treatment of the green manure dressing with the nitrolime is best among these. In which the green manure dressing and the green manure dressing with different transformation promoter could boost production. compared to the treatment without the green manure dressing, The rice output were respectively increased 22 kg/667 m2, 24.2 kg/667 m2, 40.1 kg/667 m2 and 47.2 kg/667 m2 by using the green manure dressing and the green manure dressing with transformation promoter, the ammonium carbonate and the nitrolime.
