本文主要介绍了钾肥在小麦上的应用试验。试验设5 个处理,三次重复,随机排列。试验地在轻壤土、中壤土、重壤土三种类型的土壤上安排。通过试验,速效钾含量低于100 ×10- 6 的轻壤土种植小麦,宜推广使用生物钾拌种,以667m2 施200ml 生物钾为适宜用量。速效钾含量低于150×10- 6 的中壤土,推广生物钾拌种一般增产效果不显著,宜推广使用硫酸钾作底肥,硫酸钾的最佳用量为10kg667m2 。速效钾含量在150 ×10- 6 以上的重壤土,施钾肥一般无效。
This paper introduces the application of potassium fertilizer on wheat. Experiment set up five treatments, three repeated, randomly arranged. The experiment was arranged on three types of soils, light loam soil, medium loam soil and heavy loam soil. Through testing, light-loam soil with quick-acting potassium content less than 100 × 10- 6 planted wheat should be popularized using biological potassium seed dressing, and 200ml of biological potassium should be applied at 667m2. Potassium content of less than 150 × 10- 6 in the loam, the promotion of bio-potassium seed dressing general increase yield is not significant, should promote the use of potassium sulfate as the base fertilizer, the optimum amount of potassium sulfate 10kg 667m2. Available potassium content in more than 150 × 10- 6 heavy loam, potassium is generally ineffective.
