Food quality of agricultural crops depends on environmental conditions, production system and cultivation method. A plant-based nutrition with food rich in vitamins, minerals and secondary plant compounds with antioxidative properties promotes human health. This investigation was inspired by an increasing global issue on how to improve product quality while using alternative preparations. The main aim of a 3-year study was to investigate the influence of fermented manure and silica products on yield and nutritive components in peel, fruit and seeds of three pumpkin cultivars. In four replicates as block design, the effects of individually as well as combined application of biodynamic horn manure and horn silica preparation were compared to a control variant. Horn manure application significantly increased total and marketable yield. Marketable yield, contents of macroelements, total carotenoids, single carotenoids (lutein + zeaxanthin, lycopene, ß-carotene) and antioxidants (catechins, total phenols, leuco-anthocyanins) were significantly increased by horn silica use. The combination of both biodynamic preparations had a significantly increasing effect on total and marketable yield, net photosynthetic productivity, dry matter content and total and single carotenoid contents (lutein + zeaxanthin, lycopene, ß-carotene). The pumpkin trial results indicated a general growth-promoting effect by horn manure, a quality-enhancing effect by horn silica and a compensatory effect through both preparations on a high qualitative level. In accordance with other investigations, these effects did not occur in the same way in all plant species. Therefore, the effects of the biodynamic preparations should be tested in further trials on a plant species-specific basis.

生物动力制剂对巨型南瓜（Cucurbita maxima D.）生长和果实品质的影响

农作物的食用品质取决于环境条件、生产制度和栽培方法。以植物为基础的营养食品，富含维生素、矿物质和具有抗氧化特性的次生植物化合物，可促进人类健康。这项调查的灵感来自一个日益增长的全球问题，即如何在使用替代制剂的同时提高产品质量。一项为期 3 年的研究的主要目的是调查发酵粪肥和二氧化硅产品对三个南瓜品种的果皮、果实和种子的产量和营养成分的影响。在作为区组设计的四个重复中，将生物动力牛角肥和牛角二氧化硅制剂的单独施用和组合施用的效果与对照变体进行比较。牛角肥的施用显着提高了总产量和可销售产量。通过使用角二氧化硅，可销售的产量、常量元素、总类胡萝卜素、单一类胡萝卜素（叶黄素 + 玉米黄质、番茄红素、β-胡萝卜素）和抗氧化剂（儿茶素、总酚、无色花青素）的含量显着增加。两种生物动力制剂的组合对总产量和可销售产量、净光合生产力、干物质含量以及总和单一类胡萝卜素含量（叶黄素 + 玉米黄质、番茄红素、β-胡萝卜素）具有显着增加的影响。南瓜试验结果表明，牛角粪具有普遍的促生长作用，牛角二氧化硅具有提高质量的作用，并且两种制剂都具有较高的质量水平的补偿作用。根据其他调查，这些影响在所有植物物种中都不会以相同的方式发生。所以，
