- 摘要:
- 以3年生红心火龙果为试材，研究了树体喷施化学防冻剂及根施化学物对其抗冻性及抗冻生理的影响，旨在探讨效果好、成本低、作用稳定的防冻技术。结果表明：树体喷施防冻剂的同时根施磷酸二氢钾、谷氨酸和多效唑可显著提高火龙果茎内的脯氨酸和可溶性还原糖的含量（P＜0.05），明显提高了火龙果的抗冻能力，防冻效果以0.5%的羧甲基纤维素钠混悬液+根施1%磷酸二氢钾、0.2%谷氨酸和4 mg/L多效唑混合溶液组合最佳，没有出现受冻现象。该防冻技术能较好地解决火龙果种植区北移广东清远地区的冻害问题。
- Abstract:
- With 3-year-old red pitaya (Hylocereus undulatus Britt)as the test material,the control experiment was carried out to study the tree body spraying chemical antifreeze and root applying of chemicals on the frost resistance and antifreeze physiology of red pitaya，to discussed a good effect，low cost，stable stabilizing effect antifreeze technology.The results showed that，spraying antifreeze and tree root application of potassium dihydrogen phosphate,glutamic acid and paclobutrazol,could significantly improve proline and soluble sugar of pitaya in stem(P<0.05),and significantly improve the ability of antifreeze of pitaya,the best antifreezing effect was the methylcellulose sodium 0.5% suspension+root application 1% potassium dihydrogen phosphate，0.2% glutamic acid and 4 mg/L paclobutrazol did not appear the phenomenon of freezing.The anti freezing technology could solve the problem of pitaya planting in North area of Qingyuan in Guangdong.
