葡萄的常规扦插育苗,一般利用多芽扦插,需种条量大,这对新品种的大量繁育不利,为此,可采用单芽插塑料营养袋快速育苗技术。 一、装袋:在北方冻土区,应在冬前准备好营养土。营养土比例为粗粒河沙:田园肥土:腐熟有机肥等于2:1:1,沙、土肥过筛后混匀即可。 塑料袋宽8厘米,长16厘米袋底两角剪2个孔,以利排水透气,装土时用简易漏斗将口撑开,装满后将土蹲实,土面距袋口1.5厘米左右,为管理方便,在地表摆成80～100厘米宽的育苗带。
Common cuttage nursery grapes, the general use of multi-bud cutting, the need for a large amount of species, which is not conducive to a large number of new breeding varieties, this can be a single shoot plastic bags nutritional nurturing technology quickly. First, bagging: Frozen soil in the north, should be prepared before winter nutrition soil. Nutritional soil proportion of coarse sand: pastoral soil: decomposed organic fertilizer is equal to 2: 1: 1, sand, soil and fertilizer can be sieved after mixing. Plastic bag width of 8 cm, 16 cm long bag bottom corner cut 2 holes to facilitate drainage of breathable, with a simple funnel when loading the mouth to open the mouth, filled with soil squat real soil distance from the pocket about 1.5 cm , For the management of convenience, placed in the ground 80 ~ 100 cm wide nursery belt.
