目的:探索适宜宁夏海原县的绿肥种植技术模式。方法:豌豆肥力与密度田间试验。结果:豌豆的不同播量对豌豆生育时期、土壤耕层养分及产量影响较大,在同等肥力条件下,播种密度为150kg/hm2时产量最高,为1981.67kg。结论:同等肥力条件下,适宜的播量应在120～150kg/hm2之间,过高或过低均不能达到理想的产量及经济效益。
Objective: To explore suitable greening technology of Haiyuan County in Ningxia. Methods: Field experiment on pea fertility and density. Results: Different sowing times of peas had a great influence on the nutrient and yield of peat, soil nutrient and yield of peas. Under the same fertility condition, the highest yield was 1981.67kg when sowing density was 150kg / hm2. Conclusion: Under the same fertility condition, the suitable sowing rate should be between 120 ~ 150kg / hm2, too high or too low can not achieve the ideal yield and economic benefits.
