Effects of Two Microbial Fertilizers on the Growth and Quality of Wolfberry （Lycium barbarum L. ） in the Jingtai Electric-irrigated Area | 两种微生物肥料对景电灌区枸杞产量及品质的影响

中国人. 【目的】研究有机宝（Y）和根菌宝（G）两种微生物肥料的不同用量对枸杞品质和产量的影响。【方法】试验采用随机区组设计，测定并统计各试验组枸杞的药用品质和产量，分析其差异。【结果】多糖含量以G6000mL／株Y-4800mL／株最高；类胡萝卜素含量均以4800mL／株最高，且G增效略优于Y；黄酮含量则随G肥用量增加先增后降，而在施用Y肥后普遍提高，但是用量过高（Y-7200mL／株）后出现明显的下降；甜菜碱合成则表现为G-3600mL／株和Y-2400mL／株效果最好。产量随根菌宝（G）用量增加先增后降，而随有机宝（Y）用量增加而降低，分别在施用G4800mL／株和Y-2400mL／株时达到最高。【结论】施用微生物肥料有助于提高和改善枸杞的生产性状。运用灰色综合评价评判各施肥措施的优劣程度，得到G肥中低用量G3600mL／株（评判值为17．6751）以及Y肥低用量Y-2400mL／株（评判值为16．9441），两种处理的综合优势最高。

英语. [Objective] The objective of this study was to investigate the effects of two micrdbial fertilizer （G and Y） on wolfberry＇s quality and yield. [Method] Randomized block design and grey comprehensive evaluation was used. The medicinal quality and output in each experimental group and their difference was determining and analyzed. [Results] The results indicated that the poly- saccharides content reached the maximum value under G-6 000 mL and Y-4 800mL per plant, respectively. The content of carotenoid reached in its highest level under 4 800 mL per plant. And the synergism in group G was slightly better than that in group Y. What＇s more, the flavonoid content was increased at beginning and then decreased with the increasing amount of G. It showed a generally rising trend after using Y, but it was decreased significantly after using large amount （Y-7 200 mL per plant）. The optimal effect for synthesizing betaine was under G-3 600 mL;and Y- 2 400 mL per plant, respectively. For the grain yield, it went up firstly and declined finally with the adding of content G, by contrast, it was dropped following the decrease of content Y. There is a peak of grain yield when using G-4 800 mL per plant and Y-2 400 mL per plant. [Conclusion] Microbial fertilizer has positive effect on advancing and improving production traits of wolfberry. By using grey comprehensive evaluation to judge the virtues or defect degree of different fertilization measures, it concluded that G-3 600 mL and Y-2 400 mL per Plant, evaluation value was 17. 675 1 and 16. 944 1, respectively. Those two kinds of processing have the highest comprehen- sive superiority.
