青海地区“红地球”葡萄水肥一体化技术研究

Research on Fertigation of 'Red Globe' Grape in Qinghai Province

以青海地区"红地球"葡萄为试材,分析不同施肥处理对葡萄品质和生物特性的影响。结果表明:T3处理(每667m^2施N、P_2O_5、K_2O质量为萌芽期5、1、1kg,1次;开花前2、1、1kg,1次;果实膨大期1、2、2kg,4次;果实着色期1、2、2,1次)比其它处理的果实粒质量、穗质量、可溶性固形物、维生素C含量增加,酸含量降低。说明T3处理是设施栽培"红地球"葡萄水肥一体化的有效管理方法。

The‘Red Globe＇Grape in Qinghai was used as subject to analyze the effect of different fertilization treatment on quality and biological characteristics.The results showed that the weight of berry and cluster,contents of soluble solid and vitamin C were increased and acidity content was declined compare to other treatments under the T3 treatment（The amount of fertilizing per 667m^2 was 5,1,1kg for one time at germinating stage;2,1,1kg for one time at flowing stage;1,2,2kg for four times at developing fruit stage;1,2,2kg for one time at fruit ripe stage,respectively.）.The effect of the T3 treatment was better than others about fertigation of‘Red Globe＇grape.
