摘要
为了解不同矿质肥料对蔬菜产量与品质的影响,选取多元素矿物肥、沸石、钙粉3种矿质肥料在芹菜和生菜上开展田间试验,了解其蔬菜产量和品质。结果表明:施用多元素矿物肥的芹菜和生菜均有增产效果,产量分别提高19.6%和5.3%。另外,与不施矿物肥处理相比,施用多元素矿物肥的芹菜和生菜硝酸盐含量分别降低5.0%和14.6%,维生素C含量升高显著,增幅分别达到22.8%和11.9%;总酸度下降明显,降幅分别为30.0%和18.5%;提高了芹菜和生菜中可溶性固形物含量,增幅在5%左右。综合比较看,多元素矿物肥较沸石、钙粉施用效果明显。
Field experiments were carried out on celery and lettuce by applying three different mineral fertilizers, i. e. muhielement mineral fertilizer, zeolite and calcium power, and the related indexes such as yield and quality were investi- gated. The results showed that compared with regular fertilizing treatment, the yield of celery in muhielement mineral fertilizer treatment and calcium power treatment was increased by 19. 6% and 5.3% , respectively. The nitrate content of celery and lettuce in muhielement mineral fertilizer treatment were reduced by 5.0% and 14. 6%, and the Vitamin C content was increased by 22. 8% and 11.9% , the total acidity was decreased by 30.0% and 18.5% , and the soluble solids content was increased both by 5%, respectively. In comparison with zeolite and calcium power treatments, the effect of muhielement mineral fertilizer on yield and quality was the best.
