本研究是通过不同品种(品系)施肥水平和施肥方法的正交试验,探索油菜新品系的生产潜力及其施肥技术。一、试验设计采用正交法,按品种(品系)、施肥水平及施肥方法三因素,分三个水平处理。品种(品系)为 23A×07、81—23和909。施肥水平分: (1)高肥区:每亩40斤N,年前与年后为6:4,其中有机肥30％,化肥70％。移栽
In this study, through orthogonal experiment of different varieties (lines) fertilization and fertilization methods, the potential of new rapeseed lines and their fertilization techniques were explored. First, the experimental design using orthogonal method, according to varieties (strains), fertilization levels and fertilization methods of three factors, divided into three levels. Varieties (lines) are 23A × 07, 81-23 and 909. Fertilizer level points: (1) high-fat area: 40 kg per mu N, year and year after the 6: 4, of which 30% organic fertilizer, fertilizer 70%. Transplanting
