Q:怎样嫁接四倍体刺槐?A:嫁接四倍体刺槐于每年3～4月进行为宜。砧木可选用普通刺槐和速生槐,直径为0.8～1厘米。方式可用劈接法。砧木操作点宜在距地面5厘米处,尽量做到低接。取四倍体刺槐一年生、芽饱满的梢条,剪成长3～4厘米的接穗。接穗上端有健康的萌芽,芽距接穗上端1～1.5厘米;将下端削成1厘米的双边楔形(两个对称的光滑削面),将砧木嫁接部位迅速剪断,然后从断面中央劈开,将接穗插入撬开的砧木劈口,调整接穗位置,使之与砧木劈开内层双面有较大面积的接触,并且对齐。在最短的时间内用塑料膜将接口包严,防止失水。如要领掌握得好,嫁接成活率可达90%以上。嫁接期应特别注意气象变化,刮风或降雨时不应进行室外嫁接。以嫁接方式营造饲料灌木林应适当提高种植密
Q: How to graft tetraploid black locust? A: Grafted tetraploid black locust in March to April each year is appropriate. Rootstock can be used ordinary Robinia and Sophora japonica, a diameter of 0.8 to 1 cm. Way available cleavage method. Rootstock operating point should be at a distance of 5 cm from the ground, try to be low. Take tetraploid acacia annual, bud full shoot, cut 3 to 4 cm long scion. The top of the scion has a healthy sprout, the bud from the top of the scion 1 to 1.5 cm; the lower end of the cut into 1 cm bilateral wedge (two symmetrical smooth noodles), the root stock grafting quickly cut, and then split from the center of the cross section, the scion Insert prying open rootstock split, adjust the scion position, make it with the rootstock split on both sides of the inner surface of a larger area of contact, and alignment. In the shortest possible time with a plastic film interface package will be strict to prevent water loss. If the essentials to grasp well, graft survival rate of up to 90%. Grafting should pay special attention to weather changes, windy or rain should not be carried out outdoor grafting. Grafting way to create forage shrubs should be appropriately increased planting density
