Description
Technical field
The present invention relates to field of agricultural production technologies, be specifically related to a kind of method that extends Leifsonia.
Background technology
Sugar industry is the industry of industrial or agricultural close ties, and its unit are cane yield is related to the sugarcane grower masses' economy receiptsBenefit, and its Sucrose content directly has influence on the benefit of sugar enterprise. Therefore the kind of, promoting in sugarcane production must meetPer unit area yield is high, the Sucrose of sugar enterprise's accreditation, and the each side Comprehensive Traits of this kind also adapts to local ecological condition and agriculture simultaneouslyThe requirement of thing activity etc. Join in a common effort meter according to Chinese sugar in 2012, the Main Cultivars in sugarcane district of China is No. 22, new platform sugar, new platform sugarNo. 16 series of products such as new platform sugar such as grade, cultivated area accounts for plants 73.7% of sugarcane area. These two kinds are from the mid-90 in last centuryIntroduce a fine variety later and enter China mainland sugarcane district, No. 22, especially new platform sugar after within 1999, introducing, to after 2005, become manySugarcane district, the main cultivation govern-house-variety in sugarcane district, national especially main producing region-Guangxi, according to another, the Chinese Sugar Industry association statistics of 2013 is newPlatform sugar has accounted for Guangxi main for No. 22 and has wanted 71.17% of sugar cane breed planting proportion, and new platform sugar accounts for 6.25% No. 16. Therefore, new platform sugar 22Number become genuine main cultivation govern-house-variety.
On producing, sugarcane is the crop that utilizes sugarcane stem axillalry bud to breed, as all vegetative crops, as Ma LingPotato, sweet potato, banana, strawberry, garlic etc. are the same, and long-term vegetative propagation makes virus accumulation, and harm increases the weight of, and causes production declining, productQualitative change is bad, causes heavy economic losses to production. The Major Diseases of harm sugarcane production has pineapple disease, red rot, smut, redPinta, mosaic disease, ratoon stunting disease etc. The cane planting time is longer, more serious from harm and the impact of each side, causes productAll sexual involutions, thus cause that per unit area yield is low, Sucrose declines, the stubble cane time limit shortens gradually, greatly increases and plants sugarcane planting cost.Sugarcane sows from whole that to turn over the crop cycle that the container made of bamboo, wicker, ratten, etc. heavily plants longer to eliminating, and is generally, after the new plant cane of 1 year, to stay 3 years above placesRoot sugarcane. Certainly, the stubble cane time limit is longer, and the whole planting cost in sugarcane cycle of planting is just lower, and industrial or agricultural benefit just better. General placeThe good kind of root sugarcane proterties, can stay 5 years above stubble canes, and as the sugarcane of the states such as Brazil, the U.S., Australia, institute promotesKind require stubble cane at least more than 5-8, and per unit area yield fluctuation is little, stable, this could save and plant sugarcane cost. New platform sugarSeries of products, No. 22 Zhe districts of especially new platform sugar popularizing planting the more than ten years, the symptom of this variety deterioration manifests gradually, outstandingIt is easy infection smut, not mosaic disease resisting, and drought resistance, cold resistance are not strong etc., and weakness go fromes bad to worse, and has directly caused the 1st, the 2ndYear stubble cane disconnected ridge phenomenon of being short of seedling is serious, if do not taken measures, effectively reseeds, fills the gaps with seedlings, and stubble cane is emerged and sent out a strain rateBy reduced year by year, unit are number of productive tiller also reduces year by year, causes unit are cane yield to decrease year after year, and generally arrivesThe 3rd year sugarcane grower be just forced to turn over the container made of bamboo, wicker, ratten, etc. and heavily planted.
What stubble cane will carry out fills the gaps with seedlings, and traditional way is generally three kinds, and the one, move close benefit and dredge, stubble cane is emerged and sent outWhat strain was relatively close, more passes through the old stubble cane container made of bamboo, wicker, ratten, etc. of excavated by manual work, connects root system band seedling, is then transplanted to the place on the disconnected ridge that is short of seedling, butThis method is that the old root system of stubble cane is difficult to survive more because of what move past, and new root is difficult to sprout extend and absorbs nutrient, moisture, sugarcaneSeedling is very easily rising withered dead, and survival rate is low, and spends a large amount of human and material resources, loses more than gain, and the plot that area is large adopts moreAdd difficulty, therefore, this way is eliminated already. The 2nd, culturing and transplanting seedlings, cuts the time receiving at first crop sugarcane in advance, uses at its edge of a field tail of the earthCut and grow seedlings for two bud sections with kind sugarcane tip bud, in the time that it grows to 3-4 and opens blade, run into rainy weather and be transplanted to stubble cane and be short of seedlingThe place of planting sugarcane ditch is dug on disconnected ridge in advance, after earthing, will drench normal root water. If after transplanting, run into arid weather and also will assist guaranteeArtificial trickle, until blade is turned green. The method is also to spend a large amount of human and material resources and financial resources, and is subject to the system of weatherApproximately. And the sugarcane in the whole nation more than 80% is the arid hillside field of planting in lacking man-made irrigation now, therefore, this method is in scaleIn production, also rarely have people to adopt. The 3rd, directly to reseed with the kind stem of this kind, the method is divided into again two kinds of modes, first kind of wayBe with the direct after-culture of kind stem of this kind to the disconnected ridge part of being short of seedling, the general main breed of promoting, as No. 22, new platform sugar etc., due toPlant stem and emerge according to the variation of temperature and humidity to rudiment from sowing, what need is chronic, sometimes even reaches more than 30 days; WithThe rising of spring and summer humiture, the intact stubble cane of low level bud is emerged early because sending out a strain, carry out photosynthesis assimilation photosynthate andThe ability that absorbs, utilizes nutrient early and strong, at least shift to an earlier date 20-30 days and enter above than the sugarcane seedling of reseeding tiller, jointing extends, straightTo ripe; After kind of stem is sprouted and emerged, comparatively speaking a little less than little, the seedling of seedling, particularly arrive stubble cane and tillered peak period until envelope row, easilyCovered; Can not get sufficient sunlight and carry out photosynthesis owing to reseeding sugarcane seedling, root system is small and weak in addition, is also difficult to absorb from soilTo basic nutrient, be unable to catch up with all the time the each side competition of stubble cane, cannot become productive tiller and extinction naturally, in large-scale productionOn be difficult to application, therefore, textbook or authoritative professional book are not all advocated employing. The second way, also claims stubble cane to mend in the ranksMiao Fa, adds kind of a line sugarcane in the ranks at stubble cane and between stubble cane ground, plants new plant cane in other words, although this mode is necessarilyIn degree, avoid the unfavorable factor that stubble cane early growth and quick tiller shades, robs nutrient etc., under the high condition of labor management level, littleArea test or production are also to have certain effect; But also there are many drawbacks, if be first that the new plant cane of same kind is not carriedBefore sow and manage and protect, be the speed of growth of being unable to catch up with stubble cane, the asynchronous growing way of plant on same sugarcane ground, be difficult to unifyField management. Does is the time that new plant cane is sowed in advance also difficult to control, and is that sugarcane is cut before or after receipts? next is that stubble cane in the ranks addsPlant after a line new plant cane, upset between original field management gangway or action row, during sugarcane machinery cannot be walked and be carried outA series of operations of ploughing, applying fertilizer, earthing up, certainly will increase hand labor power cost, are also difficult to use in large-scale production.
Owing to lacking the method for the prolongation stubble cane that effective, simple, sugarcane grower accepts, cause producing upper sugarcaneCrop cycle shortens, of poor benefits, becomes the bottleneck of restriction cane planting industry cost-saving synergistic, also becomes cane planting industry urgentlyOne of problem solving. Therefore, above-mentioned three kinds of traditional ways, owing to there is many drawbacks, cannot make stubble cane in scaleNeat seedling, strong sprout in production, reach the desired number of productive tiller of target output and extend the perennial root time limit.

(2) results and analysis of test
Find out from process of the test, process 1 than processing the 2 fast 14-18 days that are unearthed of sprouting, only sprout unearthed than stubble cane low level budLate 3-7 days, but process 1 to after growing to 3-4 sheet true leaf sheet, growing way has part to exceed stubble cane seedling, and to 6 trueLeaf starts to tiller, and reaches 150.1% with the tillering capacity of former stubble cane, and after jointing extends, spoke 98-296 most of plant height in osmanthus has exceeded placeRoot sugarcane. And processing 2 obviously than the stubble cane 15-25 days at least slowly that is unearthed of sprouting, sprout in some long 3-4 sheet blade side of stubble cane seedlingSoil, along with the growing way of stubble cane is accelerated, to after tillering, along with growing tall of perennial root plant, the stretching, extension of blade, processes 2 sugarcane seedlings firmGrow 2-3 and open true leaf, inevitably covered, be difficult to carry out effective photosynthesis, seedling is little, a little less than seedling, arrived stubble caneAfter plant jointing extends, process that 2 sugarcane seedlings are many dies young or be difficult to grow up to productive tiller, only have the sugarcane seedling zero of only a few away from stubble caneFragmentary star can grow up to productive tiller, but does not generally all tiller, and plant is also compared short and small. Also can find out from subordinate list 2, each process withContrast stem footpath difference is little, and the stem of processing 1 is looked and benefited osmanthus spoke 98-296 early growth and quick tiller, jointing extends morning and fast, therefore, and entiretyStem length is improved, higher than process 2 with contrast 24-29cm, processing 2 and contrast difference not obvious, in same level. TestSuccess just should be returned to number of productive tiller, these two important indexs of per unit area yield, process 1 significantly higher than process 2 with contrast,Amplitude than contrast volume increase reaches 55.20%; And process 2 also not obviously with contrast difference, further prove to utilize this kindKind stem is directly reseeded stubble cane and is difficult to succeed. Though the Sucrose of each processing has fine difference, totally also still locatesIn same level, also illustrate that the stubble cane that utilizes the kind stem of osmanthus spoke 98-296 directly to reseed No. 16, new platform sugar does not affect sucrosePoint.
In sum, two tests have obtained success. Illustrate that to utilize osmanthus this early growth of spoke 98-296 fast, whole lifeVigorous for a long time, and directly reseed the new platform sugar of the main cultivation govern-house-variety of sugarcane No. 22, the new platform of the kind stem with the kind of many advantagesThe stubble cane that No. 16, sugar has obtained the obvious raising of per unit area yield, has effectively extended the stubble cane time limit, is also conducive to grower's increase and plantsSugarcane income and cost-saving synergistic thereof. If applying of this technology, will obtain good society and economic benefit.
