Embodiment 1

[0031] A method for multiplying sugarcane healthy seedlings in the field, comprising the following steps:

[0032] (1) In early and mid-March of the first year, take the stem tips of sugarcane as explants, conduct induction cultivation and multiplication cultivation after disinfection to obtain sugarcane cluster buds.

[0033] (2) Transfer the obtained clustered buds into a culture bag with liquid medium and seal them for rooting cultivation. Liquid medium: MS+sucrose 50 g / L+ naphthalene acetic acid 5 mg / L; pack and seal the culture bag and clustered buds Transport from the tissue culture laboratory to the planting base, place the cultivation bag in a well-ventilated room without direct sunlight, close the doors and windows, and turn on the lights at night.

[0034] (3) Cultivate for 4 days for rooting. After all the roots of clustered buds grow out, open the opening of the cultivation bag, and immediately sterilize the rooted seedlings. After continuing to cultivate for 1 day, ...

Abstract

The invention discloses a method for field doubling propagation of healthy sugarcane seedlings. According to the method, sugarcane stem tips are used as explants, sugarcane cluster buds obtained frominduction and proliferation cultivation are loaded into cultivation bags, subjected to rooting cultivation, transplanted into seedling pots after rooting and subjected to nutrition cultivation, and then transplanted to a big field; when tillering seedlings of sugarcane seedlings are grown out, main stems are cut off for cuttage transplanting cultivation planting. By use of the method, one Mu of yield can be changed into two Mu of yield without affecting harvesting of sugarcane seeds at the beginning of the second year, and seeds can be supplied in batches to alleviate the problem of serious shortage of sugarcane seeds in March to April in a double-high-sugar sugarcane base; the production cycle can be shortened, the production cost is saved, and high-quality sugarcane seeds and high-yieldsugarcane are quickly harvested.

Description

technical field [0001] The invention relates to the technical field of plant breeding and planting, in particular to a method for double breeding healthy sugarcane seedlings in the field. Background technique [0002] Cane sugar industry is one of the important advantageous industries in Guangxi, which plays a decisive role in the balance of supply and demand of sugar in our country. Since the "Eleventh Five-Year Plan", Guangxi's sugarcane production has achieved rapid development, with simultaneous growth in planting area, per unit yield and total output. The overall scale of Guangxi's cane sugar industry has reached the first place in the country, and its dominant position in the country has become increasingly prominent. However, single varieties of sugarcane, degraded species, and low yield per unit area are still bottlenecks affecting the development of the sugarcane industry. Xintaisu No. 22 has been planted for more than 15 years, and it is still the leading variety ...
