我省乃至全国的果园土壤管理制度,主要是清耕或间种粮油等农作物,极少数果园由于管理跟不上而实行撩荒制。一种土壤管理制度的选择,应当符合果树生产的需要。目前,影响果树生产的因素很多,其中土壤瘠薄、营养不足是一个重要因素。我室1979年对全省60多个苹果园的土壤分析表明,土壤有机质含量为0.5～1.5％。由于调查中对低产园注意的不够,土壤有机质含量可能还低于0.5％。有机质是土壤肥力的一个重要指标,据国外报导,适合植物生长的理想的土壤有机质含量为
The orchard soil management system in our province and even in the whole country mainly consists of crops such as clearing farmland or grain crops and oil crops. A handful of orchards have been forced to abandon the management system because of their management. A soil management system of choice should be consistent with the needs of fruit trees. At present, many factors affect the production of fruit trees, including infertile soil and undernourishment are an important factor. Soil analysis of my room in 1979 in more than 60 apple orchards across the province showed that soil organic matter content was 0.5-1.5%. Due to insufficient attention paid to low-yielding areas in the survey, soil organic matter content may still be below 0.5%. Organic matter is an important indicator of soil fertility. According to foreign reports, the ideal soil organic matter content suitable for plant growth is
