    摘要:

    采用田间随机区组试验设计,研究了不施骨炭、150、300、450、600 kg·hm-2 骨炭5 个处理对土壤养分

    Abstract:

    A field randomized block experiment was carried out to study the effects of bone-biochar on soil nutrients, radish yield and quality.Five treatments were designed in this experiment: no bone-biochar, 150 kg·hm-2 bone-biochar, 300 kg·hm-2 bone-biochar, 450 kg·hm-2 bone-biochar, 600 kg·hm-2 bone-biochar.Results showed that soil organic matter, total nitrogen, available phosphorus and soil pH increased with bone-biochar increasement, soil organic matter, total nitrogen, available phosphorus and soil pH were the highest when supplied 450 and 600 kg·hm-2 bone-biochar.Compared with no bone-biochar, applied bone-biochar greatly increased radish bromass, vitamin C, soluble sugar and soluble protein content and also decreased nitrate content significantly.With the increase of bone-biochar, radish yield firstly increased and then decreased, vitamin C, soluble sugar and soluble protein content significantly increased, nitrate content of the fleshy root significantly decreased.Radish yield, nutrient content were the highest and nitrate content was the lowest when supplied 300 and 450 kg·hm-2 bone-biochar.Taken together, these results suggested that application of bone-biochar is an effective measure to improve the quality of cultivated land, increase crop yield, and optimize crop quality.450 kg·hm-2 bonebiochar worked best in soil improvement and radish increasement.
