| 摘 要： | 对影响环峡南苜蓿种子产量的磷肥、钾肥、浇水和地膜条件4个因素进行正交组合试验,结果表明: 磷肥、钾肥、磷钾肥互作对种子产量的影响较大,其次为地膜条件、磷肥浇水互作,浇水的影响最小。试验结果和生产成本综合考虑,最适宜的处理组合为:钙镁磷450 kg/hm2+硫酸钾150 kg/hm2+不铺地膜+不浇水。

| Abstract: | The 4 factors: Phosphate fertilizer, Potassium sulphate, Watering and Plastic mulching which affect the yields of Medicago polymorpha L.cv.Circle Valley have been studied. The experiment methods were orthogonal design. The results showed that the factors with the highest influence on the seed yields were Phosphate fertilizer, Potassium sulphate and the interaction of Phosphate fertilizer and Potassium sulphate; the next were Plastic mulching and the interaction between Phosphate fertilizer and Watering; the lowest was Watering. Considering the experimental results and the cost, the best combination was: 450 kg/hm2 of Fused calcium magnesium phosphate + 150 kg/hm2 of Potassium sulphate + non Plastic mulching + non Watering. |
