果树弯干整形应注意的问题一、苗木应达到一定粗度和高度。嫁接口以上１０厘米处的主干粗度在０．８－１厘米以下，高度不超过定干高３０厘米时不宜弯干，而应采用短截定干法。二、在适宜时间弯干。弯干一般应在气温回升但芽尚未萌动时进行。过早，枝干较硬易劈裂；过晚则...

Fruit trees bent stem should pay attention to the problem First, seedlings should reach a certain thickness and height. Grafting interface above the trunk thickness of 10 cm at 0.8-1 cm below the height of not more than 30 cm dry should not be bent, but should use the short cut dry method. Second, at the appropriate time to bend. Bending should generally be carried out when the temperature is rising but the bud has not yet budged. Too early, the branches are hard and easy to split; too late then ...
