Description

Technical Field

[0001] The present invention belongs to the technical field of planting, and specifically refers to a method for rapidly breeding bud seedlings for pineapple planting. Background Art

[0002] As a leading tropical fruit, pineapple occupies an important position in the global fruit market with its unique flavor and rich nutritional value. With the continuous improvement of people's living standards, the demand for pineapple continues to grow, which also promotes the continuous development and expansion of the pineapple planting industry.

[0003] However, traditional pineapple propagation methods face many challenges in practical applications. In terms of seed propagation, pineapple seeds are not only limited in quantity, but also have a low germination rate and a long growth cycle. It often takes a lot of time and effort from sowing to harvesting, and it is difficult to meet the demand for rapid market supply. Although sucker propagation is one of the more commonly used methods at present, the generation of suckers depends on the growth status of the mother plant and the quantity is relatively small. At the same time, during the process of separating suckers, if the operation is improper, it is extremely easy to damage the mother plant and suckers, thereby affecting the survival rate.

[0004] In addition, the existing pineapple propagation technologies are generally slow in propagation speed. This not only causes growers to invest more time and resources in waiting for the growth of bud seedlings, but also limits the large-scale development of the pineapple planting industry. In today's increasingly competitive market, efficient and rapid propagation methods are crucial for reducing planting costs and increasing economic benefits.

[0005] From a global perspective, the pineapple planting industry is facing more and more challenges. Factors such as climate change and land resource tension have put forward higher requirements for the planting and propagation of pineapples. Traditional propagation methods are unable to cope with these changes, and there is an urgent need for an innovative and efficient method for rapidly breeding pineapple bud seedlings. Summary of the Invention

[0006] The purpose of the present invention is to provide a method for rapidly breeding bud seedlings for pineapple planting to solve the problems of slow propagation speed and low survival rate of pineapples in the prior art.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is as follows: A method for rapidly breeding bud seedlings for pineapple planting, the method for rapidly breeding bud seedlings includes the following steps:

[0008] (1) Select a healthy pineapple mother plant. During the vigorous growth period of the pineapple mother plant, select the tillers at its base as propagation materials;

[0009] (2) Carefully separate the selected tillers from the mother plant, paying attention to maintaining the integrity of the tillers and avoiding damage;

[0010] (3) Disinfect the separated tillers with a disinfectant solution;

[0011] (4) Prepare a seedling-raising substrate and transplant the disinfected tillers into the seedling-raising substrate;

[0012] (5) Place the transplanted tillers in a suitable environment for cultivation, water regularly, and keep the seedling-raising substrate moist;

[0013] (6) Apply fertilizer at the right time during the growth process of the tillers;

[0014] (7) When the tillers grow to a certain height and have 3 - 4 complete leaves, they can be transplanted and planted.

[0015] Further, the time for selecting tillers in step (1) is from May to August every year.

[0016] Further, the disinfectant solution used in step (3) is carbendazim solution or thiophanate-methyl wettable powder solution.

[0017] Further, the disinfection method in step (3) is to soak the tillers in the disinfectant solution for 10 - 15 minutes.

[0018] Further, the seedling-raising substrate in step (4) includes the following components in parts by weight: 60 - 100 parts of humus soil, 20 - 30 parts of perlite, and 10 - 30 parts of vermiculite.
