应用微生物肥料提高砀山酥梨品质的研究

Enhancing effects of microbial fertilizer on Dangshan crisp pear quality.

对8年生砀山酥梨树施用微生物肥料试验结果表明,在高N水平下施用微生物肥料,砀山酥梨叶片N含量显著降低;P、Ca、Mg、Zn、Mn、K、Fe、B元素含量明显增加。合理施用微生物肥料可以提高产量和增加果实含糖量、糖酸比和Vc含量等,果实品质明显改善;果实耐贮性和梨果的等级显著提高。在试验条件下微生物肥料的最佳施用量为1.0kg/株。

An experiment on the effects of microbial fertilizer on the quality of 8-year Dangshan crisp pear show a remarkable decrease of N contents and an marked increase in P,Ca, Mg, Zn, Mn,K,Fe,B contents in Dangshan crisp pear leaves when treated with microbial fertilizer. Reasonable application of microbial fertilizer enhances yield and increases sugar and Vc contents, ratio of sugar to acid; and improves fruits quality. It also improves storing quality. Under the experimental conditions,the optimum application amount of microbial fertilizer is 1.0kg per tree.
