摘要
通过合江县与周边区(县)的油菜11个"3414"试验,建立油菜土壤氮、磷、钾的施肥指标体系。根据合江县地貌类型、土壤类型、耕作制度与农业生产水平的相对一致性,建立合江县油菜的配方施肥分区,确定在不同分区上不同产量的配方施肥量,便于施肥指导,科学施用肥料。
Establish a soil nitrogen,phosphorus and potassium fertlizer index system of rape through 11 ‘3414＇tests in Hejiang County and the surrounding counties.Depending on the type of landform,soil type,cropping system and the relative consistency of agricultural production level in Hejiang,establish a rape formula fertilization partitions to determine the fertilizer amount in different regions and production,and facilitate application guidance and scientific application of fertlizier.
