摘要
为了筛选红芸豆栽培的最佳施肥量,采用三因素四水平的正交设计和随机区组3次重复进行田间试验。结果表明:氮肥对红芸豆生育日数、单株荚数、单株粒重、百粒重和小区产量有极显著影响(P<0.01);磷肥对红芸豆单株粒重有显著影响(P<0.05);钾肥则对红芸豆各农艺性状无显著影响。通过直观分析最终筛选出尿素375 kg/hm2,过磷酸钙450 kg/hm2,硫酸钾不施用为该区域红芸豆氮磷钾最佳施肥量。
In order to select the optimum fertilizer rate, the orthogonal design of three factors at four levels and the randomized blocks of three replications were implemented in this experiment. With the variance analysis of the experiment, the result showed that nitrogen fertilizer had a very significant effect on index of growth period, pods per plant, grain weight of plant, 100-grain weight and plot yields of red kidney bean (P〈 0.01). Phosphate fertilizer had a significant effect on grain weight of plant (P〈0.05). Potash fertilizer had no effect. Through the intuitive analysis, the optimum fertilizer rate (375 kg/hm2 of urea, 450 kg/hm superphosphate without potassium sulfate) was selected finally, which was very suitable to enhance red kidney bean. 2 of calcium the yield of
