Time：2016.
Except the amount of broadcasting and thickness of sowing, for other implantation methods with embodiment 1, test result is shown in Table 2：
The influence of 2 amount of broadcasting of table and thickness of sowing to harvest yield
The technology is analyzed, the primary growth of extremely frigid zones clover needs to undergo larger wind, and increasing application rate can ensure
Alfalfa seed is emerged.2.0 thousand grams/acre of excessive application rate, be easy to cause the competition of emergence, although being broadcast to a certain extent than conventional
The 1.0 thousand grams/acre of volume increase of kind amount, but relative to 1.5 kilograms, there is no increasing production, go back 20 kilograms of the underproduction per acre accordingly.Therefore it selects
Select 1.5 kilograms, you can ensure the emergence of extremely frigid zones clover.In line-spacing selection, line-spacing is too narrow (10cm), although can promote morning
Envelope Gansu Province of phase, but ventilation condition is poor, competition in the ranks mutually inhibits, and influences the growth of root system.Line-spacing is excessive (30cm), emergence
Afterwards, envelope Gansu Province is slower and weedy, cannot make full use of solar energy.And 15~20cm of line-spacing, it can not only ensure to emerge,
Also can promote to seal Gansu Province, in order to compete, aerial part competes light source, promotes Seedling height, therefore yield is higher.Comprehensive each processing,
When application rate is at 1.5 kilograms, line-spacing is in 15~20cm, yield highest, up to 522,000 grams/acre.
3 seed boron fertilizer rhizobium of test example are with the influence for comparing Alfalfa yield

In addition to formula, for other implantation methods with embodiment 1, test result is shown in Table 3：
3 seed rhizobium boron fertilizer of table is with the influence for comparing harvest yield
The technology is analyzed, rhizobium can promote the generation of clover root system root nodule, promote the better fixed nitrogen of plant and promote
The absorption and utilization of N P and K.The verified growth that can promote root system of plant in a certain amount of range of boron fertilizer promotes to plant
The photosynthesis of object.It is dressed seed using boron fertilizer and rhizobium, alfalfa output can be made to maintain higher level, after comprehensive each processing
Yield factor, quality compare seed：Boron fertilizer：Rhizobium=1000:30:When 15, alfalfa output highest, the ratio of this boron fertilizer and rhizobium
Example is best to the interaction effect of seed, therefore selects the processing as the technology of utilization and extention.
Influence of 4 height for the stubble left of test example to clover Herbage harvest
Kind：Dragon herds 801；
Experiment area：The Hulunbeier City pastures Xie Ertala；
Time：2016.
In addition to the height for the stubble left, for other implantation methods with embodiment 1, test result is shown in Table 4：
Influence of 4 height for the stubble left of table to yield
The technology is analyzed, after cradling for the first time, toothing is too low (4cm), can damage the growing point of clover, influences regenerated energy
Power influences the density of regenerated shoot phase, and to influence the yield of second batch of harvest, certainly, first batch cradles low, can increase the first planting
Clover Herbage harvest.After cradling for the first time, toothing is excessively high (10cm), can reduce grass yield when cradling, while second batch of production grass
There is no relative increases for amount.It when cradling in 6~8cm, can both ensure the yield of first planting Alfalfa, clover will not be influenced
Growing point and second batch of growth ability.It is to be noted that research of the experiment without second batch of height for the stubble left of development,
In our other experiments, it has proved that second batch of toothing 10cm, it is ensured that the yield of eldish, while can also ensure lucerne
The safe overwintering of Mu.Therefore, comprehensive analysis, toothing 6~8cm, second batch of toothing 10cm, it is ensured that herd for the year after regrowth hair harvests
Also can be that the overwintering of next year herbage provides safeguard, and then ensures the alfalfa output in next year while Herbage harvest.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
