为研究有机肥不同用量对露地蔬菜的生长、产量效益的影响,探索有机肥对露地菜田施用的最佳用量及与无机化肥的配合作用,提高肥料的利用率。2008年,北京市通州区农业技术推广站土肥室特安排此项研究。通过该试验研究得出,露地甘蓝在底施有机肥230.00kg/667m2的情况下,再合理配合二铵9.00kg/667m2,尿素10.00kg/667m2,硫酸钾8.25kg/667m2的长势及效益最佳;露地大白菜在施用有机肥390.00kg/667m2情况下,再配施二铵15.30kg/667m2,尿素16.90kg/667m2,硫酸钾14.00kg/667m2的长势及效益最佳。
In order to study the effects of organic manure on the growth and yield of vegetable in open field, the best dosage of organic manure on field vegetable field and the cooperation with inorganic fertilizers were explored to improve the utilization of manure. In 2008, Tongzhou District, Beijing Agricultural Technology Extension Station Soil Fertilizer Room special arrangements for this study. The experimental results show that under the condition of organic fertilizer 230.00kg / 667m2, the growth and benefit of 9.00kg / 667m2 diammonium, 10.00kg / 667m2 urea and 8.25kg / 667m2 potassium sulfate are reasonable. Chinese cabbage under open field application of organic fertilizer 390.00kg / 667m2, with the application of diammonium 15.30kg / 667m2, urea 16.90kg / 667m2, potassium sulfate 14.00kg / 667m2 growth and benefits of the best.
