Problems solved by technology

According to related reports, the cuttings of thornless Chinese wolfberry are mainly used in spring and summer. As the temperature rises in spring, cuttings are prone to infection of germs, and the survival rate of cuttings is not high. The rooted cuttings still need to be transplanted again. Causes damage to the seedlings and increases the cost of seedling cultivation; summer twig cuttings are in the high temperature period in summer, and full-light spraying system devices are required for implementation. This method greatly limits the large-scale breeding of seedling production enterprises and seedling farmers

Embodiment 1

[0028] A kind of thornless Chinese wolfberry rapid propagation method:

[0029] (1) Maternal cultivation

[0030] ① Female parent selection: choose 3-year-old thornless Chinese wolfberry as the female parent of cuttings;

[0031] ② Soil fertilization: apply 3000-5000kg of organic fertilizer per mu in winter;

[0032] ③ Soil insecticide and disinfection: Apply 100kg of phoxim medicinal soil + 100kg of carbendazim medicinal soil per mu in spring, by dissolving 0.75kg of 50% phoxim EC and 50% carbendazim wettable powder in appropriate amount of water and mixing Made of soil 100kg;

[0033] ④ Treatment of female parent: In mid-March in spring, cut off 2 / 3 of the basal branches of the thornless female parent, and only keep about 1 / 3 of the small branches, spray 20% fenvalerate EC 2000 times + 50% Mala Phosphorus 1000 times solution;

[0034] ⑤ Topdressing: At the end of April and at the end of May, apply 10kg / mu of urea with a total nitrogen content≧46.4% twice, and apply 15kg / ...

Abstract

The invention discloses a quick propagating method of ilex cornuta varfortunei, and belongs to an asexual propagation method of plants. The method comprises the following steps of (1) cultivating female parents; (2) performing cutting; and (3) performing management after cutting. According to the method disclosed by the invention, through technical measures of cultivating an ilex cornuta varfortunei cutting seed tree, building a cutting bed through a garden field and the like, lignified branches of the ilex cornuta varfortunei are used for cutting in autumn, and the survival rate of the cut branches is increased by 20-30% than that of the cut branches in spring and in summer; the rooting rate of cutting shoots is as high as 93.8% or above, and the cut seedlings grow quickly, are high in adaptability, and quick form adult seedlings; and the defects that cutting shoots are high in attack rate, low in survival rate, high in seedling culturing cost and the like in spring and summer are overcome, and the quick propagating method has important popularization and application values in the clonal seedling propagation practice of the ilex cornuta varfortunei.

Description

technical field [0001] The invention relates to a method for asexual propagation of woody plants, in particular to a method for propagation of thornless Chinese wolfberry cuttings. Background technique [0002] spineless wolfberry ( Ilex cornuta var. fortunei), a natural variation of the holly family Ilex, with entire leaves, evergreen shrubs or small trees. It is evergreen in all seasons, beautiful in tree shape, and bright red in fruit that does not fall in winter. It is an important ornamental tree species in landscaping in the Yangtze River Basin. [0003] The vegetative propagation of plants can maintain the excellent characteristics of the female parent, and the vegetative propagation methods of thornless Chinese fructus mainly adopt methods such as cuttings. According to related reports, the cuttings of thornless Chinese wolfberry are mainly used in spring and summer. As the temperature rises in spring, cuttings are prone to infection of germs, and the survival rat...
