我县为葡萄栽培新区,冬季不培土防寒,葡萄生产中常见越冬期枝蔓抽干现象。导致地上部枝蔓残缺不全,产量降低,树势明显衰弱。为此,1985—1986年,我们对枝蔓抽干原因进行了调查。发现枝蔓抽干与枝蔓充实度、落叶早晚、品种、整形修剪、施肥等有关。 My county is a new viticulture area, winter is not cultivated soil cold, vine production during the winter wintering dry branches phenomenon. Resulting in incomplete dendritic shoots on the ground, yield decreased, the apparent weakness of the tree. To this end, 1985-1986, we conducted a survey of the reasons for the spores of dried vine. Found that the branches and stems drained and dendrite profundity, deciduous leaves, varieties, plastic pruning, fertilization and so on.
