人们长期以来对干杂果树存有“耐瘠薄与耐粗放管理”的错误认识,以致造成这些果树的产量低而不稳。近几年,经生产实践证明,干杂果树只要加强管理,板栗每亩产量可达400千克,山楂、柿子也能获得好收成,比过去的产量提高几倍。为此,要十分重视干杂果树的管理,特别是春季管理。 The misconception that dry fruit trees have long been “resistant to infertility and extensive management” has led to low and unsteady yields of these fruit trees. In recent years, the production practice has proved that as long as the dry mixed fruit trees to strengthen management, chestnut yield up to 400 kg per mu, hawthorn, persimmons can get good harvest, several times higher than in the past. To this end, we must attach great importance to the management of dry fruit trees, especially spring management.
