The present invention relates to smoothbark birch planting technology fields, and in particular to a kind of Cultivate administration method for improving smoothbark birch sapling growing way.By smoothbark birch sapling it is long to 55~60cm high when, embroidery needle is selected to pierce 9~12 pin holes at the semi-lignified of smoothbark birch sapling top, the water suction reagent of one layer of 2~3mm thickness is wrapped to pin hole, and wraps one layer of preservative film on water suction reagent surface layer, pricks 8~10 pin holes on film；And when smoothbark birch grows first branch, identical method carries out bundle hole to smoothbark birch sapling herein, smooth bark birch seedling is in fast growing period when pricking hole twice, the reagent that absorbs water passes through moisture in pin hole absorption sapling, and under the combination of preservative film, the moisture of absorption is largely temporarily stored in water suction reagent, and it not easily runs off, sapling top is supplied at any time, improve sapling root moisture and transmission rate from nutriment to sapling top and carrying capacity, the apical dominance of sapling is improved, the quick vertical growth of sapling is promoted. |
