Hongsenhuai sophora softwood cutting propagation technology

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 cutting seedling raising, in particular to a cutting seedling raising technique of softwood of Sophora japonica. Background technique [0002] Hongsen Pagoda Tree Crown Garden is neat and beautiful, with thick green branches and leaves, large shade coverage, water resistance, early resistance, and cold resistance. It is one of the excellent tree species for greening in the vast northwestern cities. [0003] The traditional propagation method of P. pseudoacacia relies mainly on seed propagation. The superior line adopts grafting and root burying method. However, P. pseudoacacia has strong cross-pollination ability and high natural hybridization rate. The seed quality is not easy to maintain. The cost of grafting and rooting is high. It is too high and the speed is slow, which cannot achieve the purpose of rapid reproduction. The traditional method of raising seedlings of Sophora japonica can only be raised in sp...

AI Technical Summary

Problems solved by technology

[0003] The traditional breeding method of Hongsen Sophora japonica mainly relies on seeds, 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 type 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
