山东烟台地区果农对苹果丰产园有句评语:“树满园,枝满冠”。这不但形象地说明了丰产树体结构和丰产群体结构的主要特点,而且也深刻地揭示了丰产树体结构与丰产群体结构间的内在联系。“枝满冠”是丰产树体结构的主要特征,“树满园”是丰产群体结构的主要特征。“枝满冠”是“树满园”的基础,“树满园”是单位面积上实现高产的条件。现就苹果丰产树体结构与群体结构的有关问题论述如下。 Fruit growers in Yantai, Shandong, have a remark on Apple FARM: “Tree is full of trees and branches are crowned.” This not only vividly illustrates the main features of high yield tree structure and high yield population structure, but also profoundly reveals the intrinsic relationship between high yield tree structure and high yield population structure. “Full crown” is the main feature of high yield tree structure, “tree garden” is the main feature of the high yield population structure. “Full crown” is “tree garden” foundation, “tree garden” is the unit area to achieve high yield conditions. Apple crop yield structure and community structure are discussed below.
