Description
Technical field
The present invention relates to breeding plant planting technology field, specifically a kind of sugarcane health seedling original seedling stem repeats to reseed
Extend the method for the harvesting sugarcane time limit.
Background technique
Sucrose is the main body of China's sugar consumption, accounts for 90% or more of sugar consumption.Guangxi, Yunnan are the maximum sugar in China
Expect sugarcane production base, cultivated area and yield account for 80% or more of national sugar cane area and yield, and sugar industry is also two provinces (area)
The important channel of important pillar industry and farmers' income.In recent years, poor by working condition, breeding research and develop lag, single variety,
Improved variety popularization slowly, cost of labor increase that very fast, breeding Cultivate administration is unreasonable and many factors such as domestic and international price fluctuation
It influences, sugar cane planting benefit glides, and market competitiveness decline, sugar industry development and sugarcane grower increase income and be affected.
After last year harvesting sugarcane, with staying in sugarcane in soil the bud of the sugarcane container made of bamboo, wicker, ratten, etc. in suitable environmental condition (mainly temperature and wet
Degree) under rudiment be unearthed, then grow up to sugarcane strain, claim stubble cane.The perennial roots such as Australia, the U.S., Brazil 4 years or so, South Africa and Mao Li
This perennial root 4-6, the general perennial root 1-11 of Cuba are asked, some national perennial root year limit for lengths' reaches 20 years or more.However at present
China's Leifsonia time limit is relatively low, generally 2-3, has been decreased obviously to the 3rd year stubble cane yield, relative to foreign countries
Country, the stubble cane ratio and the perennial root time limit in China still show relatively low level.The reason master for causing China's Leifsonia time limit relatively low
If perennial root cultivation management technology is innovative not enough.Stubble cane typically constitutes from 70% or so of kind of sugarcane area, and stubble cane is grown good
It is bad, directly influence the total output of next year sugarcane.If ratoon sugarcane management is bad, the field disconnected ridge that is short of seedling is more, easy to breed
Pest and disease damage causes the yield of ratoon sugarcane to reduce.Sugarcane grower is when planting conventional planting sugarcane due to weather arid, without by choosing
Kind, the reasons such as sugarcane kind is of poor quality, often there is phenomenon of being short of seedling, it is insufficient, uneven to cause Basic Seedling, or because of conditions such as geographical and weathers
Limitation, the field disconnected ridge that is short of seedling are more；Or when carrying out perennial root cultivation management, it is not suitble to the seedling reseeded, is not also looked into
It lacks and fills the gaps with seedlings, stubble cane disconnected ridge phenomenon of being short of seedling happens occasionally；Be short of seedling disconnected ridge, the mismanagement of conventional planting and perennial root can all seriously affect
The yield of stubble cane shortens the time limit of perennial root.Quickly breeding goes out to be suitble to the new talent reseeded after the harvesting of sugarcane stem, then conventional new
It plants the place being short of seedling on the ground with perennial root to fill the gaps with seedlings, and carries out the management of science, be to improve planting and stubble cane yield and extension
Perennial root time limit most efficient method.
Sugarcane health seedling has many advantages, such as that the speed of growth is fast, tillering ability is strong, high at stem rate, yield is high, sowing quantity is few, can
The quick breeding for accelerating Sugarcane Superior Variety solves the problems, such as that sugarcane consumes big content of starting materials sugarcane because sowing quantity is big, while making for planting not
It is limited by time and temperature, planting sugarcane field and ratoon sugarcane is reseeded with it, not only can solve planting sugarcane
Lead to serious problem of being short of seedling because of the sugarcane seedling that do not reseed properly to ground and ratoon sugarcane, moreover it is possible to extend the perennial root time limit.Due to
Ability is squeezed by labour and sugar refinery day influenced China sugarcane difference main producing region cut between the time receiving as April December current year to next year
Part is differed, and time span is big.China's planting cane planting and harvest overlapping time are long, by labour and cut between the time receiving
(sugarcane field for needing to turn over kind must obtain etc. cut harvest after just can be carried out, and cut that receive time span long) influence, annual 1-5 month
Between have a new plant cane plantation, and planting sugarcane is by weather, planting with machinery, sugarcane kind quality etc. due to being influenced, ridge of breaking
It is commonly present when being short of seedling, seriously affects new plant cane yield.If reseed with routine seedling stem, seedling-growing time is too long, and growth lag is led
Cause reseeds seedling and is shaded, and influences sugarcane uniformity, in addition after emerge it is withered.Former, come out by stem apex detoxification tissue cultures
Sugarcane health seedling original seedling the production cost is very high (1 yuan/plant), only be applied to field-transplanting breed sugarcane kind, if using sugarcane
Health seedling fills the gaps with seedlings to sugarcane field, it is necessary to cultivate sugarcane health seedling by stages, it is higher to cultivate cost.Therefore, how to drop
The cultivation cost of low sugarcane health seedling, promotes the fast breeding of sugarcane health seedling, is realization sugarcane health seedling to sweet
The key filled the gaps with seedlings to sugarcane.
Summary of the invention
The above there are aiming at the problem that, the object of the present invention is to provide a kind of repetitions of sugarcane health seedling original seedling stem
