板栗适应性强,市场行情稳定,近年来发展很快,老的果园多采用换头更新品种、加强管理。一、夏剪整形刚刚换头的板栗,芽位集中,生长势强,易产生夹皮枝、鞭杆枝等,并发二次枝,树体松散不利于形成理想的树形,提早丰产。所以要及时进行抹芽和摘心。抹芽在4月下旬,结合绑缚防风,抹掉过密芽、偏势芽。5月底对生长势强的直立梢留20～30厘米强摘心,控制长势,促分枝培养枝组。斜生枝留50～60厘米摘心,选为骨干枝、延长枝的可长到80厘米后摘心,长势较弱不摘心,其它中庸枝、弱枝不摘心。枝势强的非骨干枝可以连续摘心2～3次,要确保骨干枝的生长优势。8月份停止摘心,以促进营养生长向生殖 Chestnut strong adaptability, market conditions stable, developed rapidly in recent years, the old orchard to replace the use of more varieties, to strengthen management. First, the summer cut plastic just Cheung chestnut, bud concentrated, growing strong, easy to produce folder sticks, whip sticks, etc., with secondary branches, loose tree is not conducive to the formation of the ideal tree shape, early yield. So in time budding and topping. Wipe bud in late April, combined with binding wind, erase the dense bud, partial potential bud. By the end of May on the growing strong vertical tip stay 20 to 30 centimeters strong topping, control the growth and promote branch cultivation branch group. Oblique branches stay 50 to 60 centimeters topping, selected as the backbone of the branches, to extend the branches can grow to 80 cm after the topping, growth is weak not topping, the other moderate branches, weak branches not topping. Strong non-stick branches can be continuous topping 2 to 3 times, to ensure the growth of the backbone of the branch. Stopping the topping in August to promote vegetative growth to reproduction
