河西走廊日光温室火龙果栽培环境控制技术研究

Study on Environmental Control Technology of Hylocereus undulatus Cultivation in Solar Greenhouse in Hexi Corridor

本研究以甘肃省河西走廊日光温室“南果北栽”的主要树种火龙果为试材,依据火龙果CAM光合作用途径,通过分析火龙果特性、气候条件和日光温室环境参数等对日光温室火龙果栽培进行了温度、光照及水分等多个单因素环境调控试验,结果表明,以火龙果生长所需水分、温度控制花的生长,以光照控制果的生长来制定全年的各项栽培技术、管理目标是比较科学的,通过解决以上问题,对日光温室火龙果整个管理水平和生产效益的提高具有现实指导意义。

Absrtact: In this study, pitaya, the main tree species in the solar greenhouse of Hexi Corridor of Gansu Province, is used as the test material.According to the CAM photosynthesis pathway of pitaya, the characteristics, climatic conditions and environmental parameters of the solar greenhouse are analyzed for the characteristics of pitaya in the solar greenhouse. Fruit cultivation has carried out a number of single-factor environmental regulation experiments such as temperature regulation, light regulation and water regulation. The cultivation technology and management objectives of this item are relatively scientific. By solving the above problems, it has practical guiding significance for the improvement of the overall management level and production efficiency of dragon fruit in the solar greenhouse.
