Abstract:
In order to improve the yield and quality of hemp fiber, studies on the nutrition requirement are very important.The effective nutrient content and accumulation of 3 cannabis varieties(Yunma No.3,Yunma No.4 and Yunma No.5)were studied by potted experiment,the roots uptake dynamic parameters of Yunma No.5 were also measured by an ion depletion experiment.The results indicated that industrial hemp contained more Ca than any other elements.The accumulation to most of the nutrients of Y5 was the highest among the 3 varieties.The results and roots′ ions uptake dynamic parameters will provide reference in rational fertilization for industrial hemp plants.
