一看根系。优质果树苗木的根系,必须具有较多的侧根,须根,同时侧根要长的均匀,不可太少或偏向一侧。苹果、梨、山楂等的1、2等果苗,应具备3条以上的侧根,根茎要达到0.4～0.5厘米以上的粗度。凡是侧根少或不具备侧根的疙瘩老苗属劣质苗,不宜购买栽植.二看高、粗度。果苗并不是越高越好,因为它与用材树木的栽培目的不同。1、2等果树苗的高度,一般能够达到1米 A look at the root system. Roots of high-quality fruit trees, must have more lateral roots, fibrous roots, while the lateral roots should be long uniform, not too little or biased to one side. Apples, pears, hawthorn and other 1, 2 and other fruit seedlings, should have more than 3 lateral roots, rhizomes to achieve 0.4 ~ 0.5 cm or more thickness. Second, those with little or no lateral root knot pimples are inferior seedlings, should not be purchased for planting. Fruit nursery is not as high as possible, because it is different from the timber cultivation purposes. 1,2 and other fruit trees height, generally can reach 1 meter
