为了验证炭基肥在安徽省青阳县水稻生产上施用的合理性与增产性,以中稻为试验对象,开展不同养分含量的炭基肥与常规施肥、空白处理肥效试验,对比其增产效果,为推广应用炭基肥提供科学依据。通过试验对比得出,基施(N—P_2O_5—K_2O为15%—10%—15%)炭基肥600kg/hm~2,追施46%尿素150kg/hm~2,肥效能满足水稻各个生育阶段需要,取得的经济效益最大。
In order to verify the rationality and yield of applying carbon-based fertilizer on rice production in Qingyang County of Anhui Province, the carbon-based fertilizers with different nutrient contents and the conventional fertilization and blank-treatment fertilizer efficiency tests were carried out using medium-sized rice as test object, comparing with the yield-increasing effect, Application of carbon-based fertilizer to provide a scientific basis. The results showed that the base fertilizer (N-P_2O_5-K_2O is 15% -10% -15%) 600kg / hm ~ 2 and topdressing 46% urea 150kg / hm ~ 2, Need, obtain the most economic benefits.
