为解决山地解冻时间与落叶松苗木萌动放叶不相吻合的问题,塞罕坝采用窖储的方式延长苗木冬眠时间、推迟苗木萌动发芽期的方法储藏苗木。1建设苗窖选择背风、向阳、地势平坦、接近水源的沙壤土、壤土或轻粘土地挖窖,挖好后用砖和水泥砌好四个侧面,地面打混凝土垫层,较窄一侧设置铁皮门,门口留有马道及上下台阶,窖顶为活动铁皮棚顶,窖长6~8m,宽3~4m,高2.5~3m。2苗木储存10月上旬落叶松苗木充分木质化后树叶开始变黄,小部分树叶已经脱落,土壤没有封冻时起苗,幼苗窖外大田假植,假植的苗木基本落叶土壤将要结冻时,进行入窖储
In order to solve the problem that the time of thawing in the mountain does not coincide with that of the larch seedling, the seedlings are stored in the saikhan dam by prolonging the dormancy time of the seedlings and delaying germination of seedlings. 1 building seedling pit selection leeward, sunny, flat terrain, close to the water of sandy loam, loam or light clay digging cellar, after digging with brick and cement to build four sides, the ground hit concrete cushion, the narrow side of the set of metal Door, the doorway has a horse road and up and down steps, the top of the pit for the activities of metal roof, pit length 6 ~ 8m, width 3 ~ 4m, height 2.5 ~ 3m. 2 seedlings stored in early October Larch seedlings fully lignified after the leaves began to turn yellow, a small part of the leaves have been shed, the soil is not frozen when the seedlings, seedlings outside the cellar field planting, seedlings planted basic deciduous soil will be frozen, Into the pit storage
