In order to achieve comprehensive quantitative evaluation of plant-breeding models in the paddy field (PBMPF), we constructed a new evaluation indicators system and a comprehensive evaluation model for PBMPF. And then, we used three typical PBMPF in Hechuan of Chongqing to verify the evaluation indicator system and comprehensive evaluation model; the evaluating results were in accord with the practical...
In the straw biogas fermentation with high concentration, ratio of nitrogen and amount of seeding material have significant effect. Experiments show that gas production is very high in early time when the urea addition level is 2.5% or 3.0%, but the methane content of gas is less than 45%. when the urea proportion is 3.5%, the gas production curve is gently, the fermentation starting time is short...
