摘要
田间及盆栽试验结果表明,在本试验条件下,亩施氯铵40kg左右,大白菜能获得较好的产量,且对蔬菜品质无不良影响;氯铵和尿素混施与尿素单施相比,其产量趋于一致,混施对提高蔬菜维生素C含量和保存土壤氮素有良好的效果。
The field and pot experiments indicated that the application rate of 600kg NH_4Cl per hect.resulted in quite high yield of Chinese cabbage(Brassica compestris ssp.Pekinensis Olsson)without any unfavourable influence on vegetable quality Besides,the application of urea alone produced the same yield as that of urea and ammonium chloride together.The application of NH_4Cl together with urea increased increased nitrogen in soils.
