Abstract

A method for cultivating sugarcane seedlings by means of sugarcane bud nodes specifically comprises the steps of selecting a fresh sugarcane which is not affected by insect attack and provided with full bud eyes to serve as a provenance, cutting off the stem of the sugarcane and only reserving a segment with bud eyes, obtaining seeds, sterilizing the seeds, then drying the seeds in the sun, preparing a seedling culture substrate with yellow soil and fine river sand, conducting planting, and finally conducting management till sugarcane seedlings emerge. By the adoption of the method, only a section of sugarcane is needed to serve as the seed, and therefore materials are saved; the cultivated seedlings are quite strong. The method facilitates the industrialized, large-scale and intensified vegetative propagation of sugarcane seedlings.

Description

Utilize sugarcane bud to save and cultivate sugarcane seedling

Technical field

This new technical field belonging to a Plants asexual reproduction method, is specifically related to utilize sugarcane bud to save and cultivates sugarcane seedling.

Background technology

Sugarcane, (formal name used at school: Saccharumofficinarum) saccharum, perennial tall and big solid draft.The sturdy prosperity of root-like stock.Stalk height 3-5 (-6) rice.The southern torrid areas such as TaiWan, China, Fujian, Guangdong, Hainan, Guangxi, Sichuan, Yunnan are extensively planted.Sugarcane is applicable to planting in fertile soil, the place that sunny, summer in the winter temperature difference is large.Sugarcane is temperate zone and tropical crops, is the raw material manufacturing sucrose, and can refines ethanol as energy substitution product.The whole world has more than 100 country to produce sugarcane, and maximum sugarcane production state is Brazil, India and China.Containing abundant sugar, moisture in sugarcane, also containing the material such as various vitamins, fat, protein, organic acid, calcium, iron be highly profitable to human metabolism, be mainly used in sugaring.

At present, sugarcane seeding cultivating method be select upright, stem slightly, the sugarcane strain of not blooming plants.Seedling has dividing of single bud, two bud seedling and polygerm seedling due to the difference containing sugarcane bud number.Production generally adopts two bud seedling, seldom adopts single bud and polygerm seedling.

Polygerm seedling: due to the relation of " apical dominance ", general upper bud is first sprouted, and upper bud can bring out the generation of growth hormone after sprouting, play supression effect to the sprouting of the next bud.Cause rudiment irregular.This phenomenon, bud number is more much more serious.

Single bud: although there is not the impact of " apical dominance ", because there is otch at the two ends of bud, easy arid dehydration and endangering by sick worm, also seldom adopts.

Two bud seedling: because the impact of " apical dominance " does not resemble polygerm seedling serious, and have a complete internode in the middle of seedling, not to resemble single bud easy dehydration and endangers by sick worm.Germination rate is high, and rudiment is more neat.Therefore generally adopt on producing.The internode of tip of a branch seedling is short, and bud is closeer, and 3-4 bud can be adopted to be one section.

No matter be which kind of method, all need too many cane stalk section, then produce a large amount of wastes.

Summary of the invention

Object of the present invention is exactly overcome the deficiencies in the prior art and provide brand-new one to utilize sugarcane bud to save cultivation sugarcane seedling.Specifically comprise: select fresh, without the full sugarcane of insect pest, eye as provenance, cane stalk section cut down, the sections only leaving eye obtains seed, basks seeds after seed disinfection, then be colonizated in and be prepared into seedling medium with yellow soil, thin river sand, finally manage to sugarcane seedling and grow.

The present invention is achieved through the following technical solutions:

Utilize sugarcane bud to save and cultivate sugarcane seedling, comprise the steps: in technical scheme

1, select provenance: select fresh, without the full sugarcane of insect pest, eye as provenance.

2, cut: cane stalk section cut down, the sections only leaving eye obtains seed.

3, sterilize: seed is soaked in the carbendazim solution of 600 times and continues immersion 2 ~ 3 hours.

4, bask seeds: the seed soaking thimerosal is pulled out, and spread solarization out to seed water stain-free.

5, nutritious bag is prepared: be prepared into seedling medium with yellow soil, thin river sand, and be sub-packed in plastic nutritional bag.

6, field planting: seed is colonizated in the matrix of nutritious bag.

7, manage: nutritious bag is moved in small-sized seedling growth greenhouse, then the humidity of seedling raising environment, air and illumination, the sterilization of nursery place and nutrient supply are managed to sugarcane seedling and grow.

The present invention both had the following advantages:

1, asexual reproduction method measure proposed by the invention is unique, and production technology is simple, easily implements.

2, by implementing the present invention, only a sections sugarcane need be taked as seed, materials are economized especially.

3, by implementing the present invention, the seedling cultivated is very healthy and strong.

4, by implementing the present invention, be more conducive to that sugarcane is seedling industrialized, scale, intensive ground vegetative propagation production.

Embodiment

Below in conjunction with embodiment, method of the present invention is further illustrated.

Utilize sugarcane bud to save and cultivate sugarcane seedling, embodiment is as follows:

6, field planting: seed is colonizated in the matrix of nutritious bag.
