无论造林还是农作物栽培,植物(树木)群体营养面积通常是用一定面积上的植株除以所占面积求得。许多林学家的根据是,由于营养面积的增加,乔木树种生长的立地条件得到改善,特别是透光性、无机营养和水分供应。乔木树种的同化器官发生一定数量和质量的变化,促进树木生长量的增加。营养面积是植株密度的倒数。在数字表达式中,营养面积表示林分中一株树应占多少平方米地面。H.P.盖奥尔基耶夫斯基还 Regardless of afforestation or crop cultivation, plant (tree) population nutrient area is usually divided by the area of ​​a certain area of ​​?? the area occupied. Many forestry experts are based on the improved site conditions for tree species growth due to increased nutrient areas, particularly translucency, inorganic nutrition and water supply. Arbor species of assimilate organs occur a certain amount and quality changes, and promote the growth of trees. Nutrient area is the inverse of plant density. In numeric expressions, the nutrient area indicates how many square meters of ground a tree should occupy in the forest. H.P. Guyogievski also
