【摘要】：贺兰山东麓酿酒葡萄产区土壤贫瘠,为了确保该地区酿酒葡萄的可持续生产,以贺兰山东麓7年生酿酒葡萄品种"梅鹿辄"为试材,研究了不同施肥处理(化肥、生物有机肥、有机无机肥,以不施肥为对照)对土壤肥力及酿酒葡萄品质的影响。结果表明:有机无机肥处理能显著提高土壤有机质含量,在降低土壤pH的同时促进速效氮、磷、钾的养分积累。生物有机肥处理在显著提高酿酒葡萄可溶性固形物含量的同时还能显著降低可滴定酸含量,有机无机肥处理在确保获得高产的同时还能改善糖酸比,提高总酚和花色苷含量。在贫瘠的碱性石灰性土壤上,有机无机肥配施是培肥地力和提高酿酒葡萄产量及品质的有效措施。
[Abstract]:In order to ensure the sustainable production of wine grape in the eastern foothills of Helan Mountain, the grape variety Merlot, a 7-year-old grape variety, was used as the test material to study the different fertilization treatments (chemical fertilizer, biological organic fertilizer), in order to ensure the sustainable production of wine grape in the eastern foot of Helan Mountain. The effects of organic-inorganic fertilizer on soil fertility and wine grape quality were studied. The results showed that the organic matter content in the soil was significantly increased, and the available nitrogen and phosphorus were promoted at the same time as the decrease of soil pH. The content of soluble solids in wine grape was significantly increased by biological organic fertilizer treatment, and the titratable acid content was also decreased, while the ratio of sugar to acid could be improved by the treatment of organic and inorganic fertilizer. In the barren alkaline calcareous soil, the combined application of organic and inorganic fertilizer is an effective measure to improve the fertility and the yield and quality of wine grape.
