A kind of method for raising seedlings by cuttings

Abstract

The invention relates to a Hongsenhuai sophora softwood cutting propagation technology comprising the following steps: (1) a seedling bed is constructed, wherein a bed is arranged in a nursery shed, and a cutting medium is arranged on the seedling bed; (2) a cutting period is selected, wherein cutting is carried out around May to August; (3) cutting clipping and treatment are carried out, wherein pruning shears used for cutting softwoods should be sterilized and disinfected by using 95% ethanol; cutting is carried out after the pruning shears are air-dried; 1 / 3000 carbendazim is sprinkled 2h before cutting insertion until the medium is thoroughly wetted; and the softwoods are soaked for 10min by using 1 / 3000 carbendazim and 3000ppm naphthaleneacetic acid; and (4) the softwoods are inserted into the seedling bed medium with spacings of 8-10cm, wherein the insertion depth is 2 / 3-3 / 4 of the lengths of the cuttings, and that one bud of each cutting is maintained above ground. With the Hongsenhuai sophora softwood propagation technology, a technical problem of Hongsenhuai sophora summer propagation is solved, such that Hongsenhuai sophora nursery can be carried out all year. With the method, Hongsenhuai sophora fast propagation is facilitated, and female parent excellent features are maintained.

Description

technical field [0001] The invention relates to the technical field of seedling raising by cuttings, in particular to a method for raising seedlings by cuttings of young branches of Sophora japonica. Background technique [0002] The crown of Hongsen locust tree is beautiful, the branches and leaves are dark green, the shade coverage is large, it avoids water, resists early morning, and is cold-tolerant. It is one of the excellent tree species for urban greening in Northwest China. [0003] The traditional propagation method of Hongsen Sophora japonica mainly relies on seed propagation, and the excellent varieties adopt grafting and root burying methods, but Hongsen Sophora japonica has strong cross-pollination ability, high natural hybridization rate, and the seed species is not easy to maintain. The cost of grafting and root burying It is tall and slow, so it cannot achieve the purpose of rapid reproduction. The traditional seedling raising method of Hongsenhuai can only ...

Problems solved by technology

[0003] The traditional propagation method of Hongsen Sophora japonica mainly relies on seed propagation, and the excellent varieties adopt grafting and root burying methods, but Hongsen Sophora japonica has strong cross-pollination ability, high natural hybridization rate, and the seed species is not easy to maintain. The cost of grafting and root burying High and slow, unable to achieve the purpose of rapid reproduction

The traditional method of raising seedlings of Hongsenhuai can only raise seedlings in spring, and cannot raise seedlings when the temperature is high in summer and autumn. Moreover, tissue culture of Hongsenhuai has a long hardening period, low survival rate and high cost; it is not suitable for large-scale promotion
