Description

A kind of production method of Xinjiang big Leaf alfalfa seed
Technical field
The present invention relates to biological field of planting, and in particular to a kind of production method of Xinjiang big Leaf alfalfa seed.
Background technology
Alfalfa (Medicago sativa) is that pulse family clover belongs to perennial herb, the title for having " King of Pasture ", tool There is crude protein content high, grass yield is high, reproducibility is strong, resistance to cradle, the features such as utilization periods are long.Stem is upright, grow thickly down to prostration, Four prismatics, hairless or micro- by pubescence, branches and leaves are luxuriant.Seed is avette, long 1-2.5 millimeters, smoothly, yellow or brown.Florescence 5-7 Month, the fruiting period 6-8 months.The alfalfa spring of the high Dormancy rating in In Middle And Lower Reaches of Changjiang River more early enters growth animated period, after cradling Reproduction speed is fast, long using the time, and production potential is high.With flourishing for herbivorous stock raising, particularly China milk industry develops Update phase is in, the demand of high-quality high protein roughage increasingly increases, and the cultivated area of southern area alfalfa is continuous Expand.Alfalfa can be cradled 6-9 times in southern area unicast whole year, and dry matter production can be more than 12.9 × 103kg/hm2, most Height can reach 23.7 × 103kg/hm2, crude protein content is stable more than 18%, can reach 26%.The high pale reddish brown lucerne of Dormancy rating Mu is in the annual green in southern area, using the time at the beginning of first arrival in March 12 months.The two stage clover lifes of winter to early spring and midsummer Length is slower, can be used according to growing way, and the plot that continuous more than the 5d highest temperatures are less than 35 DEG C and have irrigation conditions can be cradled Utilize.
Originate in Asia Minor, Iran, the band of Transcaucasia one.There is cultivation all over the world or in semi-wild state.It is born in The ground such as Tian Bian, roadside, wilderness, grassland, riverbank and cheuch.Plantation is feed and herbage extensively for Eurasia and countries in the world.
Alfalfa have the title of " King of Pasture ", and its purposes protruded is exactly feeding, because alfalfa nutrition is rich Richness, palatability is good, and yield is high, all has important value in hay production, ensiling and grazing meadow planting；Particularly pale reddish brown lucerne It containing abundant protein, mineral matter, multivitamin, several amino acids in the cauline leaf of Mu, blue or green can both raise, ensiling, also may be used With modulate green hay, processing grass meal, or mixed feed or mixed fodder first-class Vegetable protein sources.Therefore, South Botanical Development The production of square alfalfa, for promoting the development of China's animal husbandry safe animal products, meeting the market demand, increase animal husbandry economy Benefit, the income for improving numerous peasants and herdsmen, suffer from great meaning.In addition, alfalfa is not only excellent forage grass, more it is rich in Multiple nutritional components, trace element, can for extracting alfalfa saponin, clover flavones, Alfalfa Polysaccharide, cumarin etc., have it is edible, Medical value and healthcare function.Furthermore, plantation alfalfa is increased soil fertility in which can also accomplish kind, with conserving water and soil, improved soil, Optimization Planting structure effect (it is observed that the roots of alfalfa of plantation 3 years is deep up to more than 3m, clover root amount 0.3-0.5 × 104kg/h)。
Clover is distributed mainly on warm area, is substantially in zonal distribution, the U.S., Canada, Italy, method on the Northern Hemisphere State, north of China and former Soviet Union south are main producing regions；In the Southern Hemisphere, there are fairly large cultivation, such as Ah root in only some countries The court of a feudal ruler, Chile, South Africa, Australia, New Zealand etc..Whole world cultivated area about 3100 × 104H ㎡ (are counted) for 2013, the U.S. Cultivated area is maximum, and area is more than 1000 × 104H ㎡, account for the 33% of total cultivated area；Argentina second, Canada the 3rd, China the 5th, about 140 × 104H ㎡, account for the 4.5% of total cultivated area.
Alfalfa originates in West Asia Iran, during B.C. 115 years Emperors Wu Di of the Han dynasty, and opening to give the best account of makes that area, by pale reddish brown lucerne Mu takes China Xi'an to, is planted extensively on NORTHWEST CHINA, North China, northeast and other places from this, as China it is most ancient, it is most important plant One of herbage is trained, alfalfa production is increasingly becoming northern China Provinces (regions), particularly Loess Plateau, rural economy In Novel pillar industry, therefore the masses in area have rich experience to kind of an alfalfa above, and scientific research department is to planting pale reddish brown lucerne Mu had many researchs, and had many scientific achievements.However, Alfalfa Grass Yield because growth year is different with natural conditions and Excursion is very big, broadcasts rear 2-5 general 3-6 × 10 of green forage yield4Kg/h ㎡, hay yield 0.6-1.2 × 104kg/h㎡。 In the north, First Year is planted, 1-2 batches can only be cradled, economic benefit is relatively low, after Second Year, yield progressivelyes reach stabilization, every year 3-4 batches can be cradled.High term is 2-3, is reached after high term, with the extension of growth year, yield is gradually reduced, therefore The clover optimum utilization time limit is generally 5-6.By annual output hay amount 0.6-1.2 × 104Kg/h ㎡ are calculated, and the existing alfalfa ground of China is total Area 140 × 104H ㎡ can produce dry clover 840-1680 × 104t。
The market capacity of alfalfa product is huge, and one is development cowboying (milk cow), sheep (milch goat), fowl, and demand is big, according to Statistics, Shanghai City milk cow company breeding milk cow is up to 4 × 104Head or so, needs alfalfa dry measure 1.2 × 10 year4T, the whole nation how many Individual milk cow company, milch goat company, poultry-farm, required alfalfa product are very considerable；Two be special livestock breeding (such as ostrich) The rise of phytophage special animalses aquaculture and extensive development, as the new consumption market of alfalfa product；Three be feed Industrial expansion needs alfalfa product, because the country there is no a mixed feed manufacturer by alfalfa product at present It is included within Vegetable protein sources, regardless of whether considering from feed-use grain is reduced, or from mixed feed nutritional ingredient is improved, drops Low production cost considers, the important development trend that feed a part grain is future in feed industry is replaced with alfalfa product, Increase from China human mortality and cultivated land area is irreversible, this big fundamental realities of the country of grain demand pressure is seen, this development trend It will turn into again inevitable；Animal husbandry demand, special cultivation demand, feed industry demand sum are produced far beyond alfalfa Product are existing to produce dry clover 840-1680 × 10 per year4T level, domestic market capacity has much on earth, is predicted according to the Chinese Academy of Agricultural Sciences, The year dry matter production of China's alfalfa product only accounts for the 5% of tomorrow requirement total amount at this stage.City of the alfalfa product country Field capacity is huge, causes the concern of some external feed producers, for example, the alfalfa green grass or young crops that China in 1994 sign with Canada Hay import deal amount oneself more than 1 × 104T, is ten times of the export volume of the alfalfa product of China.In recent years, China's grass Supply falls short of demand in the international market for product, and the country such as America and Europe is increased to the demand of alfalfa hay powder with annual 30% speed Long, its price is higher by more than 4 times than corn.
The approach of 95% alfalfa product consumption is solved, one is to increase the yield per unit area, two be to expand plantation Area.In a sense, northern China passes through long-term plantation, increase area and the plasticity increase the yield per unit area All oneself is fairly small, but the superior south of geographical conditions then has ample scope for one's abilities, and therefore, either examines from meeting the market demand Consider, or from consideration of transforming agricultural production, Alfalfa Growing center of gravity south, which is moved, will turn into alfalfa production Development trend.From China, north and south geographical conditions differ greatly, and the short time is wanted to break away from demand pressure of the market to alfalfa product again From the point of view of power, this development trend will turn into inevitable again.
Xinjiang Big Leaf Alfalfa is in China's western growth history about more than 2000 years, and Xinjiang big Leaf alfalfa is that the whole nation is excellent Good local alfalfa variety, and field peasants and herdsmen select, cultivate and adapt to local climate and cultivate consciously for a long time, The good forage kind confirmed by national herbage variety validation board.In the Xian Yi cities Zhong Shu Yutian Counties great Ye of Hotan Prefecture seven Alfalfa Growing area is most, kind is most excellent, just there is the pale reddish brown original seed clovers of great Ye in more than 40 years of plantation in mountain area.
Xinjiang big Leaf alfalfa is that pulse family clover belongs to herbaceos perennial, and blade is especially big (to be gone out greatly compound leaf area to be more than 8cm2), it is original in style.Plant reaches as high as 2.1 meters or so.Root system is especially flourishing, and main root is thick obvious in cone, lateral root Knurl of taking root larger, grow thickly stem eye on rhizome, stem eye develops into stem, plant shape is upright, and root neck branch is more, and many persons are up to 100 More than individual, stem was hollow, sturdy in four prismatics, cane, and blade is especially big, late-maturing based on flower purple, 100-110 days breeding time. But quality is tender.Leaf margin has serration at leaf top 1/3.Flower is raceme, has short handle, is made up of 20-30 little Hua, flower Be preced with butterfly, it is pale reddish brown based on, spend lasting one month.Pod spiral shape, 1.5-2.5 circles, pod includes 7-9, seed, seed kidney It is type, yellowish-brown, glossy.2.3 grams or so of mass of 1000 kernel.Stem/leaf ratio is 1.24-1.44：1, Ratio of dry to fresh matter of leaves is 4.16-4.68：1, it is raw The phase is educated for 100 days or so.
