Embodiment 1～10

[0031] (1) At the beginning of September 2020 and the beginning of June 2021, collect branches of the current year's "Chinese Girl" holly that grow robustly, are free from diseases and insect pests, and have the same length and thickness. Cut each branch into 9 cuttings, 3 cuttings at the upper, middle and lower parts, each cutting contains 3 axillary buds, and keep 2 upper leaves. The upper end of the cuttings was cut horizontally at 0.3 cm above the axillary buds, and the lower end was cut obliquely to obtain cuttings.

[0032] (2) Soak and sterilize the cut cuttings in 80wt% carbendazim wettable powder 1000 times liquid for 15min. Align the biological lower ends of the sterilized cuttings downwards, and tie every 60 into a bundle. Dip the base 2cm of the bundled cuttings into hormone solutions of different types and concentrations for 15 seconds at medium speed (see Table 1). Prepare the perlite, peat soil and vermiculite according to Table 1 and place them in the cutting...

Abstract

The invention discloses an efficient cutting propagation method for ilex rugosa cornuta 'Mesog', which comprises the following steps: (1) selecting current-year ilex rugosa cornuta 'Mesog' branches and pruning to obtain cutting slips; (2) soaking and disinfecting the cutting slips, soaking the biological lower ends of the disinfected cutting slips into a hormone solution, taking out the cutting slips, and inserting the cutting slips into a matrix; (3) carrying out daily management on the cutting slips after cuttage, and controlling the temperature and humidity. According to research, the optimal cutting rooting scheme of ilex rugosa cornuta 'Mesog' is as follows: treating middle cutting slips for 15 seconds by 3000 mg/L IBA, and cutting the middle cutting slips in a mixed matrix of peat soil, perlite and vermiculite with the proportion of 2:1:1. According to the method, the rooting time of ilex rugosa cornuta 'Mesog' can be shortened by more than 10 days, the rooting rate reaches 100%, the rooting number reaches more than 51.67 +/-5.48 per plant, the rooting effect is greatly improved, and a foundation is laid for popularization and application of ilex rugosa cornuta 'Mesog'.

Description

technical field [0001] The invention relates to the technical field of holly propagation, in particular to a high-efficiency cutting propagation method for 'Chinese girl' holly. Background technique [0002] The evergreen tree species of the genus Ilex (Ilex) have evergreen leaves in four seasons, beautiful tree shapes, bright and bright fruits, which do not fall through winter, have high ornamental value, and have broad garden application prospects. However, most evergreen hollies are not cold-resistant, and the cultivation areas in my country are mainly concentrated in Jiangsu and the areas south of Jiangsu. A few evergreen hollies such as Ilex cornuta, Ilex cornuta 'fortunei' and Ilex crenata 'convexa' can be used in gardens in Shandong and surrounding areas, but their cold resistance is average. All suffered severe freezing damage in the extremely low temperature of -18°C in the winter of 2015 in Shandong. [0003] 'Chinese maiden' holly (Ilex rugosa × cornuta 'Mesog')...
