Description

The cultural method of gold silver grass 2
Technical field
The present invention relates to technical field of pasture cultivation, the high-yield culturing side of a kind of gold silver grass 2 Method.
Background technology
Gold silver grass 2 is grass, uprightly grows thickly, has the strongest tillering ability, and individual plant every year may be used More than tiller 80 strain, can be rated as the king in grass.Gold silver grass 2 is to be hybridized also by African wild Herba penniseti and grassiness Limit acclimatization culture through 18 years forms.It is subordinate to Angiospermae, Monocotyledonae, grass family, wolf tail Grass belongs to
Gold silver grass No. 2 (biological properties) is to be hybridized by African wild Herba penniseti and grassiness and through the pole of 18 years Limit acclimatization culture forms.Be that a kind of wide adaptability, degeneration-resistant row be strong, crude protein and the high plant of sugar part content. Having drought resisting, waterlogging, impoverishment tolerant, cold-resistant, fast growth, yield is high, nutritious, good palatability, Plantation in 1 year, can utilize more than 20 years, continuously suitably on tropical, subtropical zone and height above sea level less than 1400 meters ground District plants
Gold silver grass 2 is the torrid zone, subtropical plant.Temperature starts growth, 20--35 degree at about 10 degree For suitable growth temperature, growth retardation during less than 8 degree, stop growing when less than 5 degree, need less than subzero three degree Take protective measure.Within 2008, Guizhou Province's maximum is congealed under weather (-3-5), gold silver No. 2 safe overwinterings of grass. Spring in 2009 sprouts sprouting and grows vigorously.No. 2 spies of grass are drought-enduring for gold silver, in March, 2013-October Guizhou Big damage caused by a drought test, around crops are a piece of withered and yellow, and gold silver grass 2 is the most is green and luxuriant.Gold silver grass 2 With long term growth in water, can purify the ability extra-heavy of sewage, 2012 at Pollution Treatment of Dianchi Lake dirt water test In, the total nitrogen in the time Dian Chi sewage of only 2 months has dropped one times, and total phosphorus has dropped 5 times, and sewage becomes substantially Clear free from extraneous odour, pollution treatment effect is obvious
Gold silver No. 2 photosynthesis biochemical route of grass are C4 approach, belong to typical four-carbon plant, and luminous energy effect turns Rate is high, and the Biomass of unit are is higher than other herbages, is the plant effectively utilizing solar energy most economical. At present, the bottleneck that No. 2 photosynthetic with rising ratios of gold silver grass are relatively low is broken.Therefore, No. 2 tools of gold silver grass Have drought resisting, waterlogging, impoverishment tolerant, cold-resistant, fast growth, yield high (general yield 10~20/ Mu) etc. characteristic, it has also become water, the dual-purpose grass in land
Gold silver grass 2 (botanical character) belongs to fibrous root system plants, and fibrous root has underground stipes to grow, is grown in In the soil layer of 60~80 centimetres, the longest up to more than 4 meters, spreading range is wide, and gold silver grass 2 becomes Water and soil conservation, the preferable plant of bank protection Rocky Desertification Control, this grass uprightly grows thickly, and plant is up to 4-5 rice, stem Thick 3~4 centimetres, internode is shorter, and general joint number is 20~35, and joint is prominent less, and brood cell highlights.Then Planting many tillers more than 25~40, many reaches more than 80.The multiple underground being born near surface of tiller or ground Upper joint, after harvesting, tiller is more neat, sturdy, more cuts tiller the most.Spring plants best, and general tiller can reach 25-40, compared with other grassiness gramineous, Pennisetum hydridum, Herba pennisetis etc., its blade soft and succulency, leaf Color is dark green, and greenery number is many, and palatability is more preferable.
The factor of influence of gold silver No. 2 cultivations of grass:
1, illumination: the photosynthesis that light is plant provides energy, is the gold silver No. 2 necessary bars depended on for existence of grass One of part, current all herbages gramineous are desirable that and are grown in sun-drenched place.China is mostly District, annual global radiation is 90~130 kilocalories/square centimeter.Wherein North China, East China major part are 120~130, Southwest is 90~110, and Sichuan is 80~90, the most all meets gold silver No. 2 growth needs of grass;
2, temperature: heat is the essential condition of the activity of sustaining life.Temperature directly influences gold silver grass 2 and plants It is the activity of various enzyme in object, thus affects its metabolism and i.e. synthesize and catabolic process.Temperature not only affects gold The yield of silver grass 2, and have influence on the sprouting of seed.By temperature in gold silver No. 2 growth courses of grass Three kinds of situations of impact point: one is minimum temperature, and two is optimum temperature, and three is maximum temperature.At optimum temperature Time various enzymolysis can coordinate best gold silver grass No. 2 plants in metabolic process, most beneficial for growth. When the low minimum temperature of temperature or higher than maximum temperature time, the activity of enzyme is suppressed by strong, simultaneously high temperature and The cell of plant is produced and directly destroys by low temperature, and protein denaturation causes Plant death, and temperature also directly affects The photosynthesis of plant and Repiration, under the conditions of existing scientific and technological level, large area that heat is varied and controlled Amount condition is relatively difficult, and therefore, the arrangement of planting season is to obtain higher yield under the same conditions Serve important function;
3, moisture: moisture is the key condition affecting gold silver No. 2 growths of grass.Photosynthesis, Repiration, Being required for hydrone participation in organic synthesis and catabolic process, water is again that mineral matter nutritional absorbs and transport Medium.The saturation state in soil can directly or indirectly affect the photosynthesis of plant.Root Absorption merit during hydropenia Can decline, leaf occurs withering all of a sudden, and pore is closed, and affects carbon dioxide and enters, and photosynthesis declines, moisture mistake Many, root system anoxia, suppress root respiration, anaerobic bacteria can produce noxious substance, be unfavorable for root system Growth.Our province most area rain heat same season, 4~JIUYUE be the season that epidemic disaster is high, rainfall accounts for entirely The 70~90% of year, megathermal period and rainfall are conducive to the growth of gold silver grass 2 with the climatic characteristic in season;
4, soil and nutrition: soil is gold silver No. 2 material bases depended on for existence of grass.The fertility of soil, knot Structure, pH value are all closely related with the growth of gold silver grass 2.Gold silver No. 2 adaptabilities to soil of grass are very strong, In the presence of water, desert ground, sand ground, stony desertification ground, salt-soda soil, bare place can grow, and All can normal growth in the range of pH value 3~12.In the ordinary course of things, the content of organic matter is high, and granule is tied Structure is good, and the soil that water conservation fertilizer conservation is good can obtain high yield.
