猕猴桃绿枝扦插,其成活率在80%以上,而且成本低、省工省时,技术简单,易于操作,是一种行之有效的苗木繁殖方法。1、扦插时间。一般在6月上旬至9月下旬扦插为宜。2、枝条的选取。应从中壮年优良单株上选取当年生半木质化的枝条,粗度以0.6厘米左右为宜,剪成有2—3个节一段的插穗。距上端芽约1—2厘米处剪平,留1/2—1片叶或剪去所有叶片,下端紧靠节下剪斜口。3、扦插。扦插床应选择地势较高,土质疏松和有一定保水能力的旱土。将土地翻耕后,整理成宽1米左右,高25厘米的苗床,在床面掺一定河砂,用0.5—1%的高猛酸钾进行1—2次土壤消毒。扦插条上切口须涂抹接蜡,并用2000—5000ppm 的吲哚丁酸或萘乙酸浸泡插条基部3—4小时,或用清水浸泡4—5小时。最后把扦插条按株距8—10厘米,行距15—20厘米的
Kiwi green branch cuttings, the survival rate of more than 80%, and low cost, saving time and labor, technology is simple, easy to operate, is an effective method of seedling reproduction. 1, cutting time. Generally in early June to late September cutting appropriate. 2, the choice of branches. Should be selected from the middle-aged good single plant lignified branches, coarseness of about 0.6 cm, cut into 2-3 sections of a cuttings. From the top of the bud about 1-2 cm at the cut, leaving 1 / 2-1 leaves or cut off all leaves, close to the lower section under the cut oblique mouth. 3, cutting. Skeletal bed should choose a higher terrain, loose soil and have a certain ability to dry soil. Till the land after tilling, finishing into a width of about 1 meter, 25 cm high seedbed bed, mixed with a certain river sand, with 0.5-1% of high potassium montanoate 1-2 times soil disinfection. Cuttings on the incision to be coated with wax, and with 2000-5000ppm indole butyric acid or naphthalene acetic acid soaking cuttings base 3-4 hours, or soaked with water for 4-5 hours. Finally, cuttings according to the plant spacing of 8-10 cm, spaced 15-20 cm
