寒地水稻品种龙盾104吸肥量及施肥技术研究
Study on Uptake and Fertilization Fechnique of Rice Variety Longdun104 in Cold Area
摘要
Abstract
In order to study the uptake and fertilization fechnique of rice variety longdun104 in cold area,different fertilizer levels experiment was carried out based on controlled irrigation.By analyzing experiment data,the result showed that the fertilizer uptake of total nitrogen、total phosphorus、total potassium of above-ground plants of Longdun104 were among 116.5～204.0、76.5～109.5、178.5～223.5 kg/hm2 total nitrogen、total phosphorus、total potassium uptake proportion of above-ground plants were 2.0∶1.0∶2.3,total nitrogen、total phosphorus、total potassium uptake of per 100 kg rice production were 1.856、0.909、2.065 kg.In the condition of higher soil fertility and adequate fertilizer,the yield of longdun104 could reach above 9 000 kg/hm2 under the fertilizing amount of 240 kg/hm2.关键词
