内蒙昭乌达盟地处中纬度中温带半干旱地区。无霜期115—146天,年降雨量350—450毫米,有效积温2800—3200℃,年平均气温3.6—5℃。盟内果园多建在丘陵沙荒地上,土壤有机质贫乏,尽管投放大量化肥,树势仍然衰弱,花芽形成的少,果品产量不高,农家肥无论数量、质量和运输能力都远不能满足果树发展的需要。为了解决这一矛盾,宁城县巴林果园从1974—1981
Inner Mongolia Zhaowuda League is located in the mid-latitude in temperate semi-arid areas. Frost-free period of 115-146 days, the annual rainfall of 350-450 mm, the effective accumulated temperature 2800-3200 ℃, the annual average temperature of 3.6-5 ℃. The alliance orchard is mostly built on lowlands of hilly land, the soil organic matter is poor, despite the release of large amounts of fertilizers, shrubs are still weak, flower buds formed less fruit yield is not high, regardless of quantity, quality and transport capacity of farmyard manure can not meet the development of fruit trees need. In order to solve this contradiction, Ningcheng County Barin orchard from 1974-1981
