梨幼树期是梨树整个生育期中重要的时期,搞好冬剪是树体管理的关键。经多年的生产实践,总结出梨幼树修剪十措施。 1 因树作形留骨架。梨树多数品种成枝力低。个体间生长差异大,在整形选留骨干枝时,要根据植株的生长状态培养树形,不能强求一律,这样可充分发挥植株的生长优势,使其早成形,早结果。 2 低干、矮冠有层间。随着矮密栽培的不断扩大和普及,梨树形的发展趋势是低干、矮冠、级次少、角度大、层间清,要求 Saplings of pear is an important period of the whole growth period of pear. To improve winter scissors is the key to tree management. After many years of production practice, summed up the pear saplings ten measures. 1 because of the tree shape left skeleton. Most varieties of pear tree branch force is low. Individual differences in the growth of large, in the selection of the backbone stay plastic surgery, according to the growth of the state of the tree culture, not rigidly, so that plants can give full play to the advantages of growth, early formation, early results. 2 low dry, dwarf crowded. With the continuous expansion and popularization of low-density cultivation, pear-shaped development trend is low dry, low crown, less grade, angle, clearance between the requirements
