山葡萄(Vitis amuresis Rupr)是东北地区的野生果树,其果实是酿制驰名中外的山葡萄酒的原料,经济价值较高.山葡萄由野生变为人工栽培,仅有二十多年的历史,有关它的营养特性和需肥规律乃至合理施肥问题,国内外尚无系统资料.为了提高山葡萄产量,我所从1979年~1982年对不同产量水平的山葡萄植株和立地土壤进行营养诊断,为其合理施肥提供依据.现将结果整理如下.一、试验区的基本情况试验区设在吉林省左家,即本所山葡萄园内,地处北纬44°东经126°,海拔243.5米.早霜期9月20日,晚霜期5月25日.年平均气温3.6℃.山葡萄由萌芽至果熟期间的有效积温全值为2,500℃.年降水679
Vitis amuresis Rupr is a wild fruit tree in northeastern region and its fruit is the raw material of the famous mountain wine of China and foreign countries with high economic value. The mountain grape has been changed from wild to artificial and has only about 20 years of history. The nutritional characteristics, the law of fertilization and even the fertilization, there is no systematic data at home and abroad.In order to increase the yield of mountain grape, we made the nutritional diagnosis of the mountain grape plants and the stand soil with different yield levels from 1979 to 1982, The results are summarized as follows: I. The basic conditions of the pilot area The experimental area is located in the left home of Jilin Province, namely the Mount Benshan vineyards, located at 44 ° N longitude 126 ° E, 243.5 meters above sea level. Early Frost Period September 20 Day and night frost on May 25. The annual average temperature is 3.6 DEG C. The effective accumulated temperature of grapevine from germination to fruit ripening is 2,500 DEG C. Annual precipitation 679
