(一)试验材料与方法(1)试验地点与材料试验地点:博斯坦乡博斯坦村土壤质地:肥沃的沙壤土砧木:无核白葡萄接穗:全球红葡萄。(2)试验处理与设计本试验从4月15日开始每隔10天嫁接一次,至到6月25日,每次嫁接8条,总共嫁接64条。嫁接方法:砧木的选择:当年发出的嫩枝于地面15~20厘米处平剪,然后砧木茎中间垂直切入3厘米深。接穗的选择:留当年发出的嫩枝1~2芽,去掉叶片,保留叶柄,接穗下端2~3厘米长削成楔形。然后将楔形的接穗插入砧木中间的裂缝口,两边的形成层要对齐,若砧木粗,接穗细时,要把一边的形成层要对齐。宽1厘米的塑科薄膜绑好,为保持接穗的湿度,把接穗的上端也绑好。(二)试验结果与分析在不同时期的嫁接成活率如表(1)。
(1) Test Materials and Methods (1) Test Site and Materials Test Site: Bostan Village, Bostan Township Soil Texture: Fertile sandy loam Rootstock: Seedless White Grape Scion: Global Red Grape. (2) Test Treatment and Design The experiment was conducted once every 10 days from April 15 till June 25, with 8 grafts each and a total of 64 grafts. Grafting methods: rootstock choice: the year branches issued on the ground 15 to 20 cm flat cut, and then rootstock stem vertical cut into 3 cm deep. Selection of scion: leave the shoot that year issued 1 to 2 buds, remove the leaves, leaving the petiole, scion bottom 2 to 3 cm long cut into wedges. Then the wedge-shaped scion inserted into the gap between the rootstockstock mouth, both sides of the formation of layers to be aligned, if the rootstock coarse, scion fine, to the side of the formation layer to be aligned. 1 cm wide plastic film tied, in order to maintain the scion humidity, the upper end of the scion also tied. (B) test results and analysis Grafting survival rates at different periods as shown in Table (1).
