    摘要:

    采用盆栽试验,设置3种生物炭(苹果枝条炭、烟草秸秆炭和玉米秸秆炭)、2种施用量(30 g/kg和60 g/kg)共7个处理,研究不同生物炭处理对玛瑙红樱桃苗期生理生化特性的影响。结果发现,不同原料及不同用量生物炭对玛瑙红樱桃苗生理生化特性的影响存在差异,施用生物炭可促进玛瑙红樱桃苗生长,与对照相比,施加生物炭处理后的新梢长度与叶片数显著提高,增幅分别为37.50%~119.51%和2.67%~53.39%,株高与干径无显著差异。施加生物炭后提高玛瑙红樱桃苗叶片叶绿素含量、POD、SOD和CAT的活性,低施用量(30 g/kg)处理的叶绿素含量较对照增加13.35%,高施用量(60 g/kg)处理较对照增加3.96%,30 g/kg处理的苹果枝炭的POD、SOD和CAT活性显著高于对照,分别提高0.87、2.24和0.40倍。施加生物炭后均降低叶片可溶性糖、可溶性蛋白、类胡萝卜素和MDA含量,分别比对照降低15.05%、26.36%、14.05%和12.15%。通过隶属函数法分析可知,30 g/kg处理的苹果枝条炭的隶属函数值均值最高,由此表明适宜的施用量(30 g/kg)有效地改善了玛瑙红樱桃生理生化特性,可用于其丰产优质栽培。

    Abstract:

    The Prunus pseudocerasus ‘Manaohong’ was used to study the effects of different biochar treatments on physiological and biochemical characteristics at the seedling stage to lay the foundation for applying biochar in cherry production. Three kinds of biochar including corn stalks,tobacco stalks and apple branches and two application rates including 30 g/kg and 60 g/kg were set in the pot experiment. The results showed that different biochar and different dosages had different effects on the physiological and biochemical characteristics of Prunus pseudocerasus ‘Manaohong’. The application of biochar promoted the growth of plant. Compared with the control,the length of new shoots and the number of leaves under biochar treatment were significantly increased,with increase of 37.50%~119.51% and 2.67%~53.39%,respectively. There was no significant difference between plant height and stem diameter. The application of biochar increased the activity of chlorophyll content,POD,SOD and CAT. Compared with the control,the chlorophyll content under low application rate (30 g/kg) and the high application rate (60 g/kg) increased by 13.35%,and 3.96%,respectively. The activity of POD,SOD and CAT of apple branches treated with 30 g/kg was significantly higher than that of the control,with increase of 0.87,2.24 and 0.4 times,respectively. After application of biochar,the content of soluble sugar,soluble protein,carotenoid and MDA in leaves decreased by 15.05%,26.36%,14.05% and 12.15%,respectively. The average value of the membership function of apple branches treated with 30 g/kg was the highest,indicating that the suitable application rate (30 g/kg) effectively improve the physiological and biochemical characteristics of Prunus pseudocerasus ‘Manaohong’ and can be used for its high yield and high quality cultivation.
