板栗树是强阳性树木,进入成年树以后具有大乔木的特性,因此,必须在株间相隔一定的距离才能充分受阳光获得高产。可是用嫁接苗栽植的板栗幼树结果好,所以只要在初期进行密植,就能充分利用土地,提高初期单位面积产量。在日本,较多的板栗生产者都采用密植的方法进行栽培。一、密植方法 Chestnut trees are strongly positive trees that have the characteristics of large trees after entering the adult tree and must therefore be sufficiently spaced from the plants to be fully sun-shielded. However, the chestnut seedlings planted with grafted seedlings have good results, so long as they are densely planted in the early stages, the land can be fully utilized and the yield per unit area can be increased. In Japan, more chestnut producers are growing in close planting. First, close planting method
