试验目的研究分析托尔在不同播期、不同密度、不同施肥水平等条件下的相互关系,以探讨该品种的最佳栽培组合,为我区大面积推广双低油菜良种提供一定的理论依据。二、试验设计 1.本试验采用正交法,设播期、密度、施肥三个因素,每个因素又设三个水平(如表1),即: (1)播期:10月5日,10月10日,10月15日; (2)密度:每亩一万株、一万二千株、一万四千株; (3)施肥:每亩施纯氮30斤、35斤、40斤。
The objective of the experiment was to study and analyze the relationship among Thor under different sowing dates, different densities and different fertilization levels to explore the best combination of cultivars and provide some theoretical basis for large-scale popularization of double low rapeseed. Second, the experimental design 1. The experiment using orthogonal method, set sowing date, density, fertilization of three factors, each factor and set three levels (Table 1), namely: (1) sowing date: October 5 October 10, October 15; (2) Density: ten thousand plants per mu, twelve thousand plants, 14,000 plants; (3) Fertilization: 30 pounds of pure nitrogen per mu, 35 pounds, 40 pounds.
