1 clover Herbage harvest of test example and Comparative Analysis on Technique
Test site：Hulun Buir Xie Ertala pastures；
Test variety：Dragon herds 801；
Harvest time：On August 26th, 2017.
Relatively light regulation and control and routine techniques Alfalfa seed yield situation, light control technique significantly improve the production of alfalfa seed
Amount increases production 10 kilograms of alfalfa seed than control, increases production ratio 40%, the results are shown in Table 1.
1 smooth control technique method of table and conventional method Alfalfa seed yield
Note：Seed production is harvest seed production in 2017, and extraseminal overground part is removed when biological yield harvests for seed
Divide weight.
The reason for analyzing this technology only has 5% or so to have an impact photosynthesis, with indigo plant in solar radiation spectrum
Light and feux rouges contribution are maximum, and blue light and feux rouges are referred to as light fertilizer.In photosynthesis, feux rouges is conducive to the synthesis of sugar, carbon hydrate
Object synthesizes, and accelerates to improve the stipes development of plant, extra energy changes into thermal energy, makes moisture evaporation.Blue light is conducive to albumen
The synthesis of matter, the formation of growth and young shoot to plant have larger impact, can also dominate cell differentiation, beneficial to anthocyanidin, dimension
Raw element synthesis.Meanwhile after other light are filtered, the temperature on clover upper strata is reduced, change transpiration, stomatal conductance, photosynthetic etc.
Index promotes the production of alfalfa seed.
The trace elements such as boron, zinc can promote clover to bloom, and pollen be contributed to be sprouted on column cap, the elongation of pollen tube,
The generation of pollen grain fracture phenomena is reduced, flower is reduced and comes off, ensures that fertilization is good, is conducive to pollinate, so as to improve setting percentage.
Clover belongs to zinc medium sensitive plant, and clover needs zinc amount larger, and zinc can improve the mass of 1000 kernel of alfalfa seed, there is apparent volume increase
Effect.In addition, clover absorption of nitrogen is significantly affected by zinc fertilizer, boron fertilizer.Potassium dihydrogen phosphate foliage-spray absorption rate is high, can
It solves to grow vigorous position phosphorus potassium deficiency in the crop critical period, can also adjust plant growth, make crop metabolism vigorous, photosynthetic work
With enhancing, blade plumpness is dark green, and stalk is sturdy, and setting percentage increases, full seed, has the function that increase matter volume increase.In addition, blade face
The accumulation that potassium dihydrogen phosphate is conducive to nitrogen is sprayed, has actively impact to improving grain weight and improving quality.
Influence of 2 proportion of additional fertilizer of test example to harvest yield
In addition to Application Ratio is different when top dressing, for other implantation methods with embodiment 1, result of the test is shown in Table 2：
Influence of 2 Application Ratio of table to harvest yield
Trace-element fertilizer such as zinc fertilizer and boron fertilizer are equal to the yield of plant growth and seed in certain concentration range
There is active influence.When more than some scope, actively impact declines or even formed toxic action, influences the normal life of plant
It is long, influence formation and the yield of seed.Our experimental result, when boron fertilizer is not no more than 30g per acre, to the growth of plant and
The formation of seed has important positive effect.Experimental data also turns out, during more than 30g, seed production and biomass decline,
And the yield reduction of seed is more, therefore during use boron fertilizer, should strictly control dosage.Zinc fertilizer is in terms of the yield of alfalfa seed
Play the role of positive.When zinc fertilizer 20g per acre when, Alfalfa seed yield highest, biological yield highest.Zinc fertilizer is excessive, inhibits
Biological yield and seed production, when zinc fertilizer usage amount is less than 20g, biological yield and seed production are not reaching to maximum, because
This sowing amount is not so good as.Phosphorus potash fertilizer imposes ratio equally at two kilograms per acre, obtains maximum biological yield and seed production, because
This integrates each processing, when seeding and fertilizing ratio is phosphorus potash fertilizer：Zinc fertilizer：Boron fertilizer=200:2:When 3, seed harvest yield highest.
Test example 3 sows influence of the line-spacing to alfalfa seed and yield.
In addition to line-spacing is different, for other implantation methods with embodiment 1, result of the test is shown in Table 3：
Influence of 3 line-spacing of table to seed production and biological yield
The characteristics of the reason for analyzing this technology, extremely frigid zones, dust storm was big.Seed production is different from grass industry, it is necessary to produce
The formation of component is measured, carries out raising seed production.When line-spacing is 20cm, biological yield caused by competition is grown toward eminence, raw
Produce amount is higher, such as processing 2.And line-spacing is excessive, the wind of extremely frigid zones causes lodging of clover etc., and strong wind causes some clovers small
Colored comes off, and is unfavorable for pollination etc..When line-spacing is in 30cm, the nutrient growth of clover maintains a higher level, and plants
Suboutput highest.Therefore, when extremely frigid zones carry out alfalfa seed production, line-spacing selection 30cm is best.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
