Description
?
Technical field
The present invention relates to field of agricultural production technologies, be specifically related to a kind of method extending Leifsonia.
Background technology
Sugar industry is the industry of industrial or agricultural close ties, the economic well-being of workers and staff of its unit are cane yield relation sugarcane grower masses, and its Sucrose content directly has influence on the benefit of sugar enterprise.Therefore, it is high that the kind that sugarcane production is promoted must meet per unit area yield, and the Sucrose of sugar enterprise's accreditation, each side Comprehensive Traits of this kind also adapts to the requirement etc. of local ecological condition and farming activities simultaneously.Join in a common effort meter according to Chinese sugar in 2012, the Main Cultivars in sugarcane district of China is the new platform sugar series of products such as No. 22, new platform sugar, new No. 16, platform sugar, and cultivated area accounts for plants 73.7% of sugarcane area.These two kinds are introduced a fine variety and are entered China mainland sugarcane district after the mid-90 in last century, especially after new No. 22, platform sugar was introduced from 1999, many sugarcane districts are become after 2005, the main cultivation govern-house-variety in national especially main producing region-sugarcane district, Guangxi, according to another, the Chinese Sugar Industry association statistics of 2013, No. 22, new platform sugar accounted for that Guangxi main wants sugar cane breed planting proportion 71.17%, sugared No. 16 of new platform accounts for 6.25%.Therefore, new No. 22, platform sugar becomes genuine main cultivation govern-house-variety.
In production, sugarcane utilizes sugarcane stem axillalry bud to carry out the crop bred, as all vegetative crops, as potato, sweet potato, banana, strawberry, garlic etc., long-term vegetative propagation, make virus accumulation, harm increases the weight of, and causes production declining, product qualitative change is bad, causes heavy economic losses to production.The Major Diseases of harm sugarcane production has pineapple disease, red rot, smut, red spot, mosaic disease, ratoon stunting disease etc.The cane planting time is longer, from the harm of each side and impact more serious, cause Different Varieties to degenerate, so that cause that per unit area yield is low, Sucrose declines, the stubble cane time limit shortens gradually, and sugarcane planting cost is planted in increase greatly.From whole, sugarcane sows to eliminating that to turn over the crop cycle that the container made of bamboo, wicker, ratten, etc. heavily plants longer, be generally after the new plant cane of 1 year, stay the stubble cane of more than 3 years.Certainly, the stubble cane time limit is longer, and the whole planting cost in sugarcane cycle of planting is lower, and industrial or agricultural benefit just better.The kind that general stubble cane proterties is good, can stay the stubble cane of more than 5 years, and as the sugarcane of the states such as Brazil, the U.S., Australia, the kind promoted requires that stubble cane is at least at more than 5-8, and per unit area yield fluctuation is little, stable, and this could save and plant sugarcane cost.New platform sugar series of products, especially new No. 22, platform sugar is the more than ten years in sugarcane district popularizing planting, the symptom of this deterioration of variety manifests gradually, especially easy infection smut, not mosaic disease resisting, drought resistance, the weakness such as cold resistance is not strong go from bad to worse, directly cause the 1st, 2nd year stubble cane disconnected ridge phenomenon of being short of seedling is serious, if do not taken measures, effectively reseed, fill the gaps with seedlings, a strain rate of emerging stubble cane will reduce year by year, unit are number of productive tiller also reduces year by year, unit are cane yield is caused to decrease year after year, generally just be forced to turn over the container made of bamboo, wicker, ratten, etc. to the 3rd year sugarcane grower heavily planted.
What stubble cane will carry out fills the gaps with seedlings, traditional way is generally three kinds, one is move close benefit to dredge, namely stubble cane emerge send out strain relatively close, more by the old stubble cane container made of bamboo, wicker, ratten, etc. of excavated by manual work, connect root system band seedling, then the place on the disconnected ridge that is short of seedling is transplanted to, but this method is that the old root system of stubble cane is difficult to survive more because of what move past, new root is difficult to sprout extend and absorbs nutrient, moisture, the very easily rising withered death of sugarcane seedling, survival rate is low, and spend a large amount of human and material resources, lose more than gain, the plot that area is large adopts more difficult, therefore, this way is eliminated already.Two is shift to an earlier date seedling raising and transplanting, namely cut the time receiving at first crop sugarcane, cut as the nursery of two bud section at the same kind sugarcane tip bud of its edge of a field tail of the earth, its grow to 3-4 open blade time, run into rainy weather to be transplanted to the stubble cane disconnected ridge that is short of seedling and to dig the place of planting sugarcane ditch in advance, after earthing, normal root water will be drenched.If after transplanting, run into dry weather and also will assist the artificial trickle of guarantee, 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 restriction of weather.And the sugarcane more than 80% in the whole nation plants the arid hillside field in lacking man-made irrigation now, therefore, this method also rarely has people to adopt in large-scale production.Three is directly reseed with the kind stem of this kind, the method is divided into again two kinds of modes, first kind of way is to disconnected ridge part of being short of seedling with the direct after-culture of kind stem of this kind, the main breed of general popularization, as new No. 22, platform sugar etc., because kind of stem is emerged according to the change of temperature and humidity from sowing to rudiment, needs chronic, even reaches more than 30 days sometimes; Along with the rising of spring and summer temp. and humidity, the stubble cane that low level bud is intact is emerged early because sending out strain, carry out photosynthesis assimilation photosynthetic product and absorption, utilize the ability of nutrient early and strong, at least than the sugarcane seedling reseeded shift to an earlier date within more than 20-30 days, enter tiller, jointing extends until ripe; After kind stem is sprouted and emerged, seedling is little comparatively speaking, seedling is weak, has particularly arrived stubble cane and has tillered peak period until envelope row, easily covered; The sunlight that can not get abundance owing to reseeding sugarcane seedling carries out photosynthesis; in addition root system is small and weak; also be difficult to from soil absorption to basic nutrient; all the time each side competition of stubble cane is unable to catch up with; cannot productive tiller be become and naturally wither away; large-scale production is difficult to application, and therefore, textbook or authoritative professional book all do not advocate employing.The second way, also stubble cane is claimed to fill the gaps with seedlings method in the ranks, namely add kind of a line sugarcane in the ranks at stubble cane and between stubble cane ground, plant new plant cane in other words, although this mode avoids stubble cane early growth and quick tiller to a certain extent and to shade, rob the unfavorable factor of nutrient etc., under the condition that labor management level is high, small size test or production are also have certain effect; But also there is many drawbacks, if be first that the new plant cane of same kind is not sowed in advance and managed and protected, be the growth rate of being unable to catch up with stubble cane, the asynchronous growing way of plant on same sugarcane ground, is difficult to carry out unified field management.The time that new plant cane is sowed in advance is also difficult to control; before or after sugarcane cuts receipts? next is after stubble cane adds kind of a line new plant cane in the ranks; upset between original field management gangway or action row; the mechanical a series of operations of carrying out intertilling, applying fertilizer, earth up of cannot walking of sugarcane; manual labor's cost certainly will be increased, be also difficult to use in large-scale production.
Owing to lacking the method for the prolongation stubble cane that effective, simple, sugarcane grower accepts, result in and shorten in the crop cycle of producing upper sugarcane, of poor benefits, become the bottleneck of restriction cane planting industry cost-saving synergistic, also become one of cane planting industry problem demanding prompt solution.Therefore, above-mentioned three kinds of traditional ways, owing to there is many drawbacks, cannot make stubble cane neat seedling, strong sprout in large-scale production, reach number of productive tiller required by target output to extend the perennial root time limit.
