为了研究施肥量对白花扁豆生产性能的影响,试验采用三因素四水平设计,以肥料品种为三因子、施肥量为四水平,共设A、B、C、D 4个施肥组合,另设一个完全不施肥处理为对照,A、B、C、D组每小区(15 m2)的施肥量分别为复合肥0.5 kg+钾肥0.12 kg+钙镁磷肥0.12 kg、复合肥0.6 kg+钾肥0.14 kg+钙镁磷肥0.14 kg、复合肥0.7 kg+钾肥0.16 kg+钙镁磷肥0.16 kg、复合肥0.8 kg+钾肥0.18 kg+钙镁磷肥0.18 kg,各处理的复合肥全部在苗期施放。结果表明:C组效果最好,白花扁豆平均生长速度最快,分蘖能力较好,3次刈割鲜草总产量最高,叶量较丰富,粗蛋白含量也最高。说明适时适量施肥对白花扁豆的生长性能具有重要意义。
In order to study the effect of fertilization on the performance of white lentils, three factors and four levels were used in the experiment. The fertilizer was three factors and the amount of fertilizer was four levels. A total of four combinations of A, B, C and D The total amount of fertilizer applied to each plot (15 m2) in groups A, B, C and D was 0.5 kg of compound fertilizer, 0.12 kg of potassium fertilizer, 0.12 kg of calcium magnesium phosphate fertilizer, 0. 6 kg of compound fertilizer, 0.14 kg of potassium fertilizer, 0.14 kg of calcium magnesium phosphate fertilizer, kg, compound fertilizer 0.7 kg + potassium fertilizer 0.16 kg + calcium magnesium phosphate fertilizer 0.16 kg, compound fertilizer 0.8 kg + potassium fertilizer 0.18 kg + calcium magnesium phosphate fertilizer 0.18 kg, and all the treated compound fertilizers were all applied at the seedling stage. The results showed that C group had the best effect, the average growth rate of white lentils was the fastest, the tillering ability was good, the total yield of fresh cut grass was the highest in three times, the leaf was rich and the crude protein was the highest. Explain timely and appropriate fertilization on the growth performance of white flower lentils is of great significance.
