板栗(Castanea mollissima)采收后加强科学管理,有利于恢复树势,防治病虫害,提高翌年产量。①翻地改土。在寒冬前进行翻地改土,其方法是:滩地、平缓坡地的成片栗园,可进行全面翻地;山坡、四旁零星栗树,可根据树体大小,以树体为中心,呈圆形翻至树冠外围0.5～0.8m。四周植被保持原状,不翻挖,以利保持水土。板栗树干四周根系分布较多,应浅翻至20～30cm;离树干较远、根系分布较少或无根系的地方,可深翻至40～50cm。对坡地上成片栗园,深翻时要与水土保持相结合,可将翻挖的砂砾、石块、树根残桩、大块草皮 Chestnut (Castanea mollissima) to strengthen scientific management after harvest, is conducive to the restoration of tree vigor, pest control and increase production in the following year. ① turn land to soil. The method of turning the soil into land before the winter is as follows: the land on the beach and the gently sloping chestnut fields can be completely turned over; the hillsides and the sporadic chestnut trees on all sides can be shaped according to the size of the tree, Turn to the crown periphery of 0.5 ~ 0.8m. Surrounding the vegetation to maintain the status quo, do not dig dig, Eli to maintain soil and water. Chestnut trunk around the distribution of more root system should be shallow turn to 20 ~ 30cm; far from the trunk, root system with little or no root place, deep plowing to 40 ~ 50cm. On the slopes into a piece of chestnut garden, deep turn when combined with soil and water conservation, digging can dig gravel, stones, roots stump, large turf
