Embodiment 1

[0043] A method for increasing the yield of sugarcane by oblique interpolation of sugarcane and prolonging the lifespan of perennial roots, using the first generation of invalid tillers of healthy sugarcane seedlings to carry out oblique interpolation in sugarcane fields, the specific steps are as follows:

[0044] (1) Use tissue culture technology to breed healthy sugarcane seedlings. When the first generation of healthy sugarcane seedlings are harvested, the invalid tillers are collected for later use.

[0045] (2) Trim the leaf sheaths of ineffective tillers; keep all the leaf sheaths that are not aged, cut off the other leaves and only keep the top 2-3 leaves of the leaf sheaths, and trim the leaves to keep the leaves 3-10cm away from the trident.

[0046] (3) Soak the pruned invalid tillers in clean water for 3.5 hours, remove and drain, and place in a cool place to dry the surface moisture; then insert the lower part of the invalid tillers into the seed soaking solution a...

Embodiment 2

[0051] A method for increasing the yield of sugarcane by oblique interpolation of sugarcane and prolonging the life of perennial roots, using the tail tip of the first generation of healthy sugarcane seedlings to carry out oblique interpolation and interplantation of sugarcane in a field, the specific steps are as follows:

[0052] (1) Use tissue culture technology to breed healthy sugarcane seedlings. When the first-generation stems of healthy sugarcane seedlings are harvested, the tail tips of the first-generation stems of healthy sugarcane seedlings are collected for later use.

[0053] (2) Trim the leaf sheaths at the tail tip; leave 2 relatively aging nodes, peel off the old leaves, leave all the leaf sheaths that are not aged, and trim the leaves, keeping the leaves 3-10cm away from the trident.

[0054] (3) Soak the trimmed tail tips in clean water for 3.5 hours, remove and drain, and place in a cool place to dry the surface moisture; then insert the lower part of the ta...

Embodiment 3

[0059] A method for increasing the yield of sugarcane by oblique interpolation of sugarcane and prolonging the life of perennial roots. The double-bud stem section of the first-generation seed stem of healthy sugarcane seedlings is used for oblique interpolation of sugarcane. The specific steps are as follows:

[0060] (1) Use tissue culture technology to breed healthy sugarcane seedlings, harvest the first-generation stems of healthy sugarcane seedlings, and cut the stems into double-bud stems with a sugarcane stem cutter; the bottom cut of the double-bud stems is close to the lower bud 1~ 2cm, the upper incision is 3-5cm away from the upper bud.

[0061] (2) Soak the double-bud stem section in clean water for 1.5 hours, remove and drain, and place in a cool place to dry the surface moisture; then soak in seed soaking solution for 15 minutes.

[0062] (3) Replant the double-bud stem section obtained in step (2) by oblique insertion on the newly planted sugarcane field lacking...

Abstract

The invention discloses a method for improving sugarcane yield and prolonging perennial root life by oblique cutting and replanting of sugarcanes. According to the method, oblique cutting and replanting are implemented in a new-planting sugarcane field or perennial root sugarcane field by the aid of healthy sugarcane seedling generation ineffective tillers and tail ends and double-bud stem sections of healthy sugarcane seedling generation seed stems. According to the method, the functions of early growth and quick tillering, high tillering characteristics and top end advantages of healthy sugarcane seedlings are fully utilized, and the healthy sugarcane seedling generation ineffective tillers and the tail ends and the double-bud stem sections of the healthy sugarcane seedling generation seed stems are replanted at seedling-less ridges of the new-planting sugarcane field or perennial root sugarcane field in an oblique cutting manner. The method solves the problem that growth of replanted seedlings and original seedlings is asynchronous in an existing replanted mode, the number of unit area productive tillers of sugarcane is guaranteed, the yield of new planting sugarcane or perennial root sugarcane is improved, and the perennial root lives can further be prolonged. The ineffective tillers and seed stem tail ends of the healthy sugarcane seedlings are fully utilized, the utilization rate of the healthy sugarcane seedlings is furthest increased, and the production cost of the healthy sugarcane seedlings is reduced.

Description

technical field [0001] The invention relates to the technical field of sugarcane breeding and planting, in particular to a method for increasing sugarcane yield and prolonging the lifespan of perennial roots by oblique interpolation of sugarcane. Background technique [0002] sugar cane( Saccharum officinarum ) is one of the important economic crops in my country, and is the main sugar crop in my country. The sucrose production accounts for more than 90% of the total sugar production in the country. Guangxi is the largest sugarcane and sugar production base in my country. The annual sugarcane planting area is about 11.5 million mu, accounting for about 60% of the national sugarcane planting area, and the sugarcane sugar production accounts for more than 65% of the country. However, in recent years, domestic sugar prices have continued to fall, and due to the impact of rising land and labor costs, the cost of sugar production in China has remained high, and the sugar cane su...
