种植绿肥是一项培肥地力经济有效的重要措施。据新疆三年的土壤有机质提升项目情况调查:种植绿肥并翻压还田(还田鲜草1 500 kg/666.7m2),土壤有机质提高1.5 g/kg、碱解氮提高5.5 mg/kg、速效磷提高1.5 mg/kg、速效钾提高9.8 mg/kg,酸碱度减少0.1个pH值。本文通过对新疆绿肥种植现状的调查,针对绿肥种植中存在的主要问题,提出了发展绿肥生产工作的建议与对策。
Planting green manure is an important measure of fertility and economic efficiency. According to the survey of soil organic matter upgrading project in Xinjiang during the past three years, planting green manures and returning to the field (1 500 kg / 666.7 m2 of returning fresh grass) increased soil organic matter by 1.5 g / kg and available nitrogen by 5.5 mg / kg, Phosphorus increased 1.5 mg / kg, available potassium increased 9.8 mg / kg, pH decreased by 0.1 pH. Based on the investigation of the status of green manure planting in Xinjiang, this paper puts forward the suggestions and countermeasures for developing green manure production in view of the main problems existing in green manure planting.
