网纹甜瓜营养液深液流栽培管理与环境调控

采用营养液深液流栽培方式,以网纹甜瓜为研究对象,根据作物生长发育不同时期对于温度、湿度、光照强度和营养液组分的不同要求,采用自主研制的温室环境测控系统,调节并控制网纹甜瓜生长的小气候环境和根际环境.一茬网纹甜瓜营养液深液流栽培实验证明,自主研制的营养液自动循环系统和基于CAN总线的温室环境测控系统能够完成预期的环境调控任务,作物生长快、产品无污染、品质优.

Muskmelon cultivated by deep flow nutrient solution and its environmental control

Cultivated by deep flow technique,different growth periods of the muskmelon have different requirements for the growing environment,comprising temperature,humidity,radiation and nutrient solution.According to the different requirements,the greenhouse microclimate and roots environment of the muskmelon were controlled by the greenhouse measurement and control system developed by the authors.The results of muskmelon cultivation by deep flow nutrient solution show that the circulatory system of nutrient solution and the measurement control system for greenhouses based on CANbus is reasonably designed reasonably.Meanwhile,maintaining at optimal environmental conditions contributes to the muskmelon growth and the fruits are pollution-free and have high quality.
