一、追肥方法:成年果园和密植果可采用全园施肥。方法是:将肥料均匀地撒于园内,然后翻入土中,深度约20厘米左右,一般结合秋耕或春耕进行。水源缺乏和稀植果园则可采用穴施,方法是:在树冠下距树干1米以外,挖坑施肥。坑数的多少视树冠的大小及施肥量而定。一般每株8—12个左右。 二、追肥部位:施肥还应尽量在根系附近,以利根系吸收,不能直接施在大根上,更不能伤害大根。一般果树吸收能力强的须根大多分布在树冠外围投
First, the method of dressing: adult orchards and close planting fruit fertilization can be used throughout the park. The method is: the fertilizer evenly sprinkled in the garden, and then turned into the soil, the depth of about 20 cm, generally combined with autumn or spring plowing. Lack of water and rare orchards can be used to plant orchard, the method is: under the tree canopy away from the trunk 1 m, digging fertilization. The number of holes depends on the size of the canopy and the amount of fertilizer applied. Generally about 8-12 per plant. Second, the top dressing site: fertilization should also be as close as possible to the root system to absorb root, can not be directly applied to large roots, but can not hurt root. Most fruit trees absorb fibrous roots mostly distributed in the outer canopy cast
