肥料增效剂γ-聚谷氨酸对小青菜产量和品质的影响
Effects of poly( γ-glutamic acid) application on yield and quality of potted Brassica chinensis
摘要
Abstract
An effect of a fortified fertilizer by poly (-y-glutamic acid) on the yield and quality of potted Brassica chinensis was studied. The results showed that the contents of chlorophyll, above ground fresh weight, nitrate, vitamin C and ammonium nitrogen with -y-PGA treatment had remarkable differences compared with the control. Under normal fertilization, the treatment with 50 mg/kg of -y-PGA led to significant increasing of chlorophyll under ground fresh weight compared with the control. In particular, the production of above ground fresh weight was increased by 8. 8%. The efficiency of ammonium nitrogen and nitrogen was improved by 10. 6% . The nitrate content decreased by 44. 8% and the content of Vc increased by 18. 1% , by using 100 mg/kg of y-PGA. When nitrogen fertilizer reduced by 15% , the treatment of 20 mg/kg of -y-PGA improved the nitrogen use efficiency by 10. 2% -11. 6%.关键词
