Embodiment 1

[0023] 1) Select a suitable breeding ground to establish a mint-sprinkled cypress female-parent area for ear-picking orchards. The row spacing of plants in the ear-picking orchard is 40cm×40cm, and the density is 2500 plants / mu;

[0024] 2) Mix peat with a volume ratio of 4:2:1:3: vermiculite: perlite: yellow core soil evenly as the matrix, and install the matrix with a 72-hole tray. The size of the tray is 54cm long, 27cm wide, and 5.5cm deep , keep the tightness of the matrix consistent, fill the plugs of the matrix, place them on the seedbed in turn, put 6 per square meter, and disinfect the matrix with 0.5% potassium permanganate solution 24 hours before cutting; The dry bulk density of the matrix is ​​0.46, the total porosity is 55.67%, the large porosity is 10.22%, the small porosity is 45.45%, and the maximum water holding rate is 1.23. pH value 5.53, EC value 0.35, total nitrogen 0.88%, total phosphorus 215.78mg / kg, total potassium 9773.55mg / kg, calcium 1678.84mg / kg, m...

Abstract

A method for cuttage propagation of juniperus chinensis 'mint julep' belongs to the technical field of plant propagation and is characterized by including steps: firstly, establishing a cutting orchard for female parents of juniperus chinensis 'mint julep' on a proper propagation land; secondly, using peat, vermiculite, perlite and loess as matrix according to a volume ratio of 3-5:1-3:0.5-1.5:2-4; thirdly, cutting an autumn shoot of last year to obtain a cutting from a female parent of juniperus chinensis mint julep at the proper cuttage time, early March; fourthly, dipping a base of the cuttage cutting in plant rooting agent Sensheng No.1 at the speed 180-220ppm for two to three seconds; fifthly, performing cuttage on a seedling bed prior to management and maintenance; and sixthly, exercising seedlings on the sixtieth to the sixty-fifth day after cuttage when rooting rate reaches about 90%. By the method, rooting is good, cutting survival rate is up to 90% which sets a new foreign record of survival rate of juniperus chinensis mint julep, and the method is simple and fast in propagating.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a cutting propagation method of juniper juniper for mint. Background technique [0002] Mint Juniper Juniperus chinensis 'Mint Julep', belonging to the genus Juniperaceae, evergreen coniferous tree, shrub, grayish brown bark, rough, flaky peeling; tree height 1.2-2.5m, crown width 1.0-2.5m, multi-branched at the base, top outward Curved, the crown is naturally shaped like a disc, graceful and generous; there are needles and scale leaves, the scale leaves are mint green, and remain bright green even in winter; the cones mature in autumn, and the light gray blue turns black. [0003] Mint is sprinkled with juniper and is light-loving, drought-resistant, heat-resistant, pollution-resistant, wind-resistant, and pruning-resistant. It can grow normally in humid to semi-arid conditions. It grows fast and avoids stagnant water. Pruned between late winter and spri...
