Six, yield detects
Harvest yield under different cultivars quality proportioning is detected, after clover harvest, through natural drying to water content 14%
~18%, weighing, statistical result such as table 3:
Each variety and quality of table 3 is with the influence for comparing harvest yield
Note: yield is average productivity ± standard deviation.
Analyze the technology, tremble with fear area's climate variability, extreme weather of high latitude takes place frequently, and clover is perennial leguminous plant, safety
It is overwintering to turn green, rationally cope with the main limiting factor that the weather such as cold spell in later spring, spring strong wind are the cold area's alfalfa growings of high latitude, pass through
The mixed seeding mode of different cold resistance kinds (Dormancy rating, overwintering index index), it is ensured that high yield, while extreme cold resistance
Kind can spend the harm of exceedingly odious weather safely again, guarantee the stable high yield of clover many years.
High latitude is trembled with fear, and area's extreme climate is severe, and minimum to subzero 49 DEG C of winter low temperature, some special time weathers are extreme
Badly, such as 2018, the cold spell in later spring and strong wind in spring cause many clovers to turn green the freezing to death of bud, cause the death of large area, and
Increase the clover of extreme anti-adversity mixed planting then well-grown.
There is difference in fast-growing and degeneration-resistant aspect between different alfalfa varieties, it is right in growth course that different quality is influenced than proportion
The competition of ground glazing, the competition to underground moisture and nutrient affect the interracial space distribution in above and below ground.It is tried by field
Test it is found that the kind to resist cold under two normal conditions is plus the mass mixings such as an extreme cold-resistant variety, can achieve high yield with
The inverse equalization point of highly resistance.On the one hand, the normal time, three kinds can safe overwintering turn green, two fast growing varietys it is quick
Growth can induce the homoplasy growth of extreme anti-adversity, participate in the competition of light and nutrient, guarantee fast-growth and high production
Amount.
On the other hand, interim, the reply of the certifiable safety of anti-adversity is carried out in some time extreme climate, guarantee is normal
Growth, and with the recovery of the reproducibility of clover root system and sprout tillers ability, guarantee that alfalfa grasslands restore rapidly simultaneously normal growth.Cause
This has a competition in conjunction with quality between kind tests, the results showed that, three kind clover mixed seeding yield are higher than individually plantation, and the effect is through counting
There are significant difference, p < 0.05 for credit analysis.And wherein, three variety and qualities are in 1:1:1, yield highest.Therefore, selection should
It is formulated as the core technology promoted.
3 regrowth hair fertilizer application formula of embodiment lodges to regrowth hair and the influence of yield
Kind: No. 1 unicast is educated by section, and No. 1, Russian Medicago varia, the quality mixed seeding such as WL168HQ are educated by section.
Test area: the Hulunbeier City pasture Xie Ertala;
Time: the sowing time 2016.
June 29 2018 soil fertility quality time, after first batch of Alfalfa harvests.
In addition to regrowth hair fertilizer formula, other implantation methods are with embodiment 1, after clover harvests, through naturally dry to water content
14%~18%, weighing, statistical result are shown in Table 4:
Influence of the 4 regrowth hair fertilizer application formula of table to lodging and yield
Note: yield is average productivity ± standard deviation;
Calcium superphosphate percentage containing phosphorus pentoxide 20%;
Potassium chloride chloride containing potassium 60% calculates ratio.
The technology is analyzed, clover fertilization mode traditionally, in order to guarantee that the stable high yield of clover, nitrogen phosphorus top dressing are the most general
Time.Although clover can act on by nodule nitrogen fixation, nitrogenous fertilizer is provided, but the field technology of crop grain production is deep-rooted.
Therefore, the application of nitrogenous fertilizer causes the waste of fertilizer, does not embody in yield.We study the high latitude Han Qu of invention
Alfalfa cultivation technology ensure that the stable high yield of clover well.But in rainwater preferable good year, for crop, summer
In the season of the exactly nutrient growth fast-growth with heavy rainfall in season, sufficient storage is provided for the maturation of reproductive growth and seed
It is standby.For clover, under dense planting technical conditions, the high water high fertile of high temperature brings the fast-growth of clover, and plant height quicklys increase,
Because density is larger, cause branch stem very thin tender, meanwhile, it is unfavorable for penetrating for wind, easily causes lodging, the after especially plants
Start within 3 years, clover enters high yield period.Therefore, for this problem, it is proposed that the phosphorus potash fertilizer of certain mass proportion is applied,
Increase the hardness of Herba Medicaginis stem, increase lodging tolerance, improves the yield of regrowth hair clover.Firstly, the application of phosphorus potash fertilizer can be improved
The growth of clover root system improves root weight, increases the rugosity of root cap.Secondly, the application of phosphate fertilizer can increase the generation of alfalfa Phylloxera,
Promote fixed nitrogen, improves fertilizer utilization efficiency, again, the application of potash fertilizer can increase the hardness of stalk, these not only increase lucerne
The lodging tolerance of Mu stalk also improves the fixing power of root cap, promotes the utilization of nitrogen, improves photosynthetic efficiency, guarantees
High yield, according to test result, high latitude is trembled with fear after area's first planting harvest, impose per acre 15 kilograms of calcium superphosphate, 5 kilograms of potassium chloride can
To increase clover lodging tolerance, the production and yield of regrowth hair Alfalfa are improved, the alfalfa output of the processing group is significantly higher than it
His each group, p < 0.05.Therefore, select the fertilization mode and formula as the core technology promoted.

After clover harvest, through natural drying, until water content 14%~18%, weighs, statistical result such as table 4:
5 general planting alfalfa hay yield comparison of table
Note: yield is average productivity ± standard deviation
Relative to the present invention program, the thickness of sowing and variety adoption of comparative example are single, and Fertilizer ratio is unreasonable.Phase
For the present invention program, the yield of general planting mode is significant lower, this species diversity through statistical analysis have conspicuousness, p <
0.05。
Reason is analyzed, dense planting technology first is higher than routine techniques grass yield.Dense planting mainly passes through the production of 3 points of raising clovers
Amount.First is that dense planting can make group seal Gansu Province as early as possible, photosynthetic efficiency is improved.Second is that dense planting promotes the competition between individual to light, plant
Strain increases plant height to higher Growth In Space.Third is that dense planting promotes the competition of individual plant pair underground nutrient and water, promote
Grow root system toward depths, root facilitates extremely frigid zones clover safe overwintering deeply.Therefore, high latitude Han Qu is increased using dense planting technology
Add cold hardiness, improves forage yield.
Also, the present invention three Cultivar mixtures plantation, medium cold-resistant fast growing variety ensure that high latitude is trembled with fear area's normal year
The high yield of forage grass, extreme cold-resistant variety is when encountering exceedingly odious weather, it is ensured that clover safe overwintering, normal growth.Together
When, normal year it has been found that when extreme anti-adversity and fast-growth Cultivar mixtures are planted, due to light, nutrient it is competing
