摘要
采用废弃物育苗基质进行蓝莓栽培试验,研究不同基质配方EC与PH对蓝莓生长发育性状的影响,以研发出更加节肥、高效的基质营养配方。以单株叶片数Y1数为指标分析蓝莓生长,主要影响因子为苗高Y2与新梢数Y6,苗高Y2的主要影响因子为茎粗Y8,新梢数Y6的主要影响因子为分枝数Y5和新梢长Y7。研究了EC与PH对蓝莓生长的影响:PH对蓝莓成活率Y9有极显著影响,EC对蓝莓生长的影响很广,EC增加1 ms/cm,蓝莓叶片数减少0.803片,叶长Y3减少0.742 cm,叶宽减少0.770 cm,新梢数Y6减少0.546个,新梢长Y7减少0.573 cm,茎粗Y8减少0.571 mm。回归分析表明,影响单株叶片数Y1数的最佳PH值为5.4,适合蓝莓生长的平均EC值为0.97 ms/cm,影响成活率Y9的最佳PH值为6.3。
The effects of EC and PH on the growth and development of blueberry were studied in order to develop a more fertilizer-saving and efficient matrix nutrition formula. The growth of Blueberry was analyzed with the index of leaf number of single plant, the main influencing factors were seedling height and new shoot number, the main factor of seedling height was stem coarse, and the main influencing factor of new shoot number was branch number and new shoot length. The effects of EC and PH on blueberry growth were studied: PH had a very significant effect on blueberry Survival, EC had a wide influence on blueberry growth, EC increased 1 ms/cm, the number of blueberry blades decreased by 0.803 tablets, leaf length was reduced by 0.742 cm, leaves broadly reduced by 0.770 cm, and the number of new shoots was reduced by 0.546. The new shoot length reduced 0.573 cm, the stem coarse reduced 0.571 mm. Regression analysis showed that the optimal PH value affecting the number of leaves per plant was 5.4, the average EC value for blueberry growth was 0.97 ms/cm, and the optimal PH value for survival rate was 6.3.
