【摘要】 研究了不同肥料处理(有机肥、有机肥+海藻肥、有机肥+菌肥、有机肥+化肥、化肥)对麦绿素用大麦产量和有关品质性状的影响。结果表明,有机肥基施配合追施化肥三期鲜叶总产和品质性状优于单施有机肥和化肥处理,嫩叶蛋白质、SOD酶、叶绿素及氨基酸含量显著高于其它处理;单施化肥干物质积累虽略高于有机肥基肥配合追施化肥,但嫩叶Vc含量显著较低;追施海藻肥、菌肥产量显著低于有机肥基肥配合追施化肥。更多还原

【Abstract】 An experiment was carried out to study the effect of different fertili zers applied as basic and top-dressing fertilizer on yield and quality of barle y leaves specially used for processing of Barley Green. The results showed that t he total fresh leaf yield of three harvests was significantly higher in the orga nic fertilizer as basic dressing and chemical fertilizer as top-dressing after c utting of above-ground parts treatment (i.e. treatment 4, OF+CF) than that in o r ganic fertilizer as basic dressing and seaweed fertilizer as top-dressing(i.e. t reatment 2, OF+SF) and organic fertilizer as basic dressing and bacterial fertil izer as top-dressing(i.e. treatment 3, OF+BF) treatments, while there was no si g nificant difference relative to the chemical fertilizer as both basic dressing a nd top-dressing treatment (i.e. treatment 5, CF). Meanwhile, some qualities, su c h as contents of protein, Vc, chlorophyll and hydrolyze amino acid, SOD enzyme a ctivity were higher in treatment 4, compared with the other 4 treatments. There was higher dry matter accumulation in the plants of the treatment 5, while lower in Vc content compared with those of the treatment 4. Seaweed fertilizer or bac terial fertilizer resulted in lower yield than organic fertilizer as basic dress ing and chemical fertilizer as top-dressing. This result indicated that the fer t ilizer practice of treatment 4 was much more beneficial to improve the quality a nd yield for the production of barley applied for barley green, compared with th e other 4 treatments.更多还原
