Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 Shown, the method for the rapid propagation of jackfruit seedling that the embodiment of the present invention provides comprises the following steps:

[0016] S101: Preparation of the slotting bed, a perlite slotting bed with a size of 4m×1.2m and a depth of 20cm. A 1.2m-high shed is built above the slotting bed. The shed is first covered with a layer of plastic film. The film seals the entire slotting bed, and then covers the outside of the film. A sunshade ...

Abstract

The invention discloses a method for rapid propagation of a jackfruit seedling. The method comprises the steps that an annual branch with half of or a leaf is selected, after the lower end of the annual branch is immersed in a rooting agent for 30 min, a healing smearing preparation and pond sludge are smeared on upper and lower notches, and then the annual branch is inserted into perlite in a cuttage mode, and sprayed with water through a nebulization sprayer; and the rooting agent is a mixed fluid, with concentrations of IBA, NAA and GA being 160 mg/L, 40 mg/L and 20 mg/L, prepared through IBA powder, NAA powder and GA powder which are dissolved sufficiently through ethyl alcohol with a mass fraction being 75%. According to the method, the used branch is the annual branch, the regeneration capacity of histocytes is strong, and the amount of germs is low; with using of the rooting agent with an optimum proportion and a loose and breathable matrix, under a condition of a suitable humidity and temperature, the branch is sufficient in moisture, and a wound is breathable; and germ infection is prevented through the yellow mud wrapped on the lower portion of the branch, and additionally the yellow mud provides nutrition for the branch. By applying of the method, the cottage rooting speed of a jackfruit seedling is accelerated, the survival rate of cuttage is increased, cost of seedling culture is reduced, and great development of the jackfruit industry can be promoted.

Description

technical field [0001] The invention belongs to the technical field of fruit tree seedling cultivation, in particular to a method for rapid propagation of jackfruit seedlings. Background technique [0002] Jackfruit (Artocarpus heterophyllus Lam.), also known as wood pineapple, is a characteristic woody economic crop in the south subtropical region of my country. It has been dominated by seed propagation for a long time, resulting in many seed variants in production. In recent years, a lot of work has been done on jackfruit grafting technology, but because of its rich milk, the survival rate of grafting is extremely low and it is difficult for workers with high requirements for grafting technology to master. "Difficulty raising seedlings" has always been the bottleneck restricting the large-scale planting and promotion of fine jackfruit varieties. Therefore, finding new technologies suitable for jackfruit seedling cultivation is of great significance for the promotion of fin...
