一、高空压条繁殖每年的6～7月,在优良植株上选择2～3年生、直径1厘米左右的健壮枝条为高压枝,选择离高压枝着生点15厘米左右的地方为高压位,在高压位上用刀把皮层剥去一圈,宽度为6厘米左右,也可以用小棒敲打该地方的皮层,敲打的强度以敲碎皮而不脱落为好。晾露3～4天,用塑料薄膜在高压位上围2～3圈,形成一个圆筒。筒的长度为25厘米,直径为10厘米。然后,在高 First, the high-altitude barbed breeding 6 to 7 months each year, the fine plants in the selection of 2 to 3 years old, about 1 cm in diameter robust branches for the high pressure branches, select the point of birth from the pressure of about 15 cm high pressure position, in the High-pressure position with a knife to peel the cortex in a circle, a width of about 6 cm, you can also tap the cortex in this place, beat the intensity to knock the skin without falling off as well. Dry exposed 3 to 4 days, with plastic film in the high pressure on the circumference of 2 to 3 laps, forming a cylinder. The length of the barrel is 25 cm and the diameter is 10 cm. Then, high
