1 促雌花技术1.1 摘心1.1.1 摘心促生结果母枝:针对幼龄树嫁接后第一、第二年枝条旺长的特性,采用多摘心的方法,使长枝变短枝,单枝变多枝,方法是,前期宜早宜轻,即当新梢长达20cm 左右时,摘除梢头;后期宜晚宜重,即当2、3次梢长达30cm 左右时,摘去7cm～10cm,可使其先端芽子得以充实饱满,成为大芽,个别摘心后仍单轴延长的枝,经冬季带“帽”修剪,仍可达到控制树冠和提早结果的目的。1.1.2 摘心促生二次果:嫁接后4年～5年生以前的幼旺树,当雌花甚少时,可采用摘心促生二次雌花结果,提高板栗产量。
1 to promote female flower technology 1.1 topping 1.1.1 topping heart to promote the growth of mother: for young trees after grafting the first and second year branches of the characteristics of long branches, the use of multi-topping method, so that the long branches shorter branches, single branch variable More branches, the method is that early early should be light, that is, when the new shoots up to about 20cm, removal of the first; late late should be heavy, that is, when the second and third shoots up to 30cm or so, pick 7cm ~ 10cm, Can make its apex bud full, become a big bud, after individual topping is still a uniaxial extension of the branch, the winter with “hat ” pruning, can still achieve the purpose of controlling the crown and early results. 1.1.2 topping promote secondary fruit: four years after grafting ~ 5 years old before the young tree, when the female flower is very small, you can use topping to promote the second female flower results, increase chestnut yield.
