“史力丰”油菜是我省沿江地区大面积推广的新品种,为明确其最佳施肥量和移栽密度,为高产高效栽培提供科学依据,特进行本试验。1 材料与方法1.1　试验设计　采取二因素裂区试验设计方法,设主因素A为亩施纯N量(kg／亩),共设三个处理,即A1 11,A2 18,A325;设裂区因素B为移栽密度(万株／亩),共设四个处理,即B1 0.4,B2 0.7,B3 1.0,B4 1.3。先主区随机排列A因素,再 “Shi Li Feng ” rapeseed is a large area of ​​new varieties along the Yangtze River in our province, in order to clarify its optimal fertilization and transplanting density, to provide scientific basis for high yield and efficient cultivation, especially for the test. MATERIALS AND METHODS A. Test Design A two-factor split test design method was adopted. The main factor A was N / kg of Mu Shi Chun. A total of three treatments were defined as A1 11, A2 18 and A325. Factor B is the transplanting density (10,000 plants / mu). There are totally 4 treatments, B1 0.4, B2 0.7, B3 1.0 and B4 1.3. The first main area randomly arranged A factor, and then
