2003年在广西畜牧研究所对引进的红皮红肉和红皮白肉2个红龙果品系,进行了系统观察和早结丰产栽培技术试验。结果表明,红皮白肉坐果率高达93%以上,易获得丰产,平均单果350g,可溶性固形物14%,可食率83.1%;而红皮红肉在自然授粉情况下,坐果率仅12%,产量较低,平均单果180g,可溶性固形物16%,可食率86.3%。在0～3℃持续15d条件下,红皮红肉老熟结果母枝冻死达93%以上,而红皮白肉抗寒性较强,仅有少量嫩梢受冻害。2品系采果期长,病虫害少,耐旱不耐涝。通过合理密植、科学修剪和合理的施肥等栽培技术可获得早结丰产的效果。
In 2003 in Guangxi Institute of Animal Husbandry on the introduction of red-skinned red meat and red white two red dragon fruit strains were observed systematically and early high-yielding cultivation techniques. The results showed that the rate of fruit setting was as high as 93%, and the average fruit yield was 350g, the soluble solid content was 14% and the edible rate was 83.1% Low yield, the average single fruit 180g, soluble solids 16%, edible rate of 86.3%. Under the conditions of 0 ~ 3 ℃ for 15 days, the red-fleshed old-aged mature fruits had over 93% freeze-thaw death while the red-white meat had a stronger cold-resistance and only a few young shoots were frostbite. 2 strains of fruit picking long, less pests and diseases, drought-resistant intolerance waterlogging. Through the close planting, scientific pruning and reasonable fertilization and other cultivation techniques can get early fruiting effect.
