为探讨黔南地区火龙果适宜的氮肥施用量,通过田间试验,研究了氮素施用量0(T0,对照)、89.1(T1)、127.2(T2)、165.3千克/公顷(T3)对火龙果产量、品质及贮藏效果的影响。结果表明,火龙果产量随着施氮量的增加先增加后降低,T2处理最高,为18557.42千克/公顷,比对照增产32.63%;火龙果单果质量随着施氮量的增加而增加;不同处理间果形指数差异不明显。施氮
In order to investigate the suitable nitrogen application rate of dragon fruit in Qiannan region, the effects of nitrogen application rate 0 (T0, control), 89.1 (T1), 127.2 (T2), 165.3 kg / ha Yield, quality and storage effects. The results showed that the output of dragon fruit increased firstly and then decreased with the increase of nitrogen application rate, the highest value of T2 was 18557.42 kg / ha, increased 32.63% compared with the control; the fruit quality of dragon fruit increased with the increase of nitrogen application rate; The difference between fruit shape index is not obvious. Nitrogen application
