[0003] Although alfalfa has the effects of clearing the spleen and stomach, clearing dampness and heat, diuresis, and reducing swelling, the current alfalfa is all used in continuous cropping. The planting method of continuous cropping will cause soil deterioration, soil nutrients will drop, and the seeds will not easily absorb nutrients, resulting in a low seed germination rate. In order to solve the problem of low seed germination rate in this continuous cropping planting method, the seeds can be made to germinate new shoots first, The seeds are then cultured and transplanted. When the current alfalfa seeds germinate new shoots, the germination rate will be affected by the hardenin

Example Embodiment
[0032] Example 1:
[0033] Such as figure 1 As shown, a device for increasing the germination rate of alfalfa under continuous cropping mainly includes: a shell for storing water 1, a shell breaking mechanism arranged inside the shell 1 to accelerate the seed shell breaking 2, arranged on the shell 1 The screen at the bottom end is used to collect and processed seeds. 3 The power mechanism 4 that can provide power to the shell breaking mechanism 2;
[0034] The housing 1 is provided with a water inlet pipe 12 and a water outlet pipe 11, and the water outlet pipe 11 is also provided with a valve 111;
[0035] Such as figure 1 As shown, the shell breaking mechanism 2 is a cylinder whose shell is a screen, and includes: a plurality of vertically arranged shell breaking cylinders 21, a feeding tube 25 for seed entry, and one used for processed seeds The discharge pipe 26 that is discharged, the feed pipe 25 penetrates to the outside of the housing 1, the discharge pipe 26 is connected t...
Example Embodiment
[0050] Example 2:
[0051] The difference between Embodiment 2 and Embodiment 1 is:
[0052] In the S1 step of the method for promoting the germination of alfalfa seeds in Example 2, the concentration of the hydrogen peroxide solution is 100 ppm.
[0053] The germination rate of alfalfa in this example: 91%
Example Embodiment
[0054] Example 3:
[0055] The difference between Embodiment 3 and Embodiment 2 is:
[0056] In the S1 step of the method for promoting the germination of alfalfa seeds in Example 2, the concentration of the hydrogen peroxide solution is 150 ppm.
[0057] The germination rate of alfalfa in this example: 88%

Abstract
The invention discloses a device for increasing the germination rate of alfalfa under continuous cropping. The device mainly comprises a shell, a shell breaking mechanism, a screen and a power mechanism. The shell breaking mechanism comprises a plurality of shell breaking cylinders, a feeding pipe and a discharging pipe; the power mechanism comprises a fixed plate, a plurality of first rotating shafts arranged at the top end of the shell breaking mechanism and used for assisting the shell breaking mechanism in moving, first rocking bars with one ends rotationally connected with the first rotating shafts, power connecting shafts rotationally connected to the other ends of the first rocking bars, a second rotating shaft fixedly arranged at the bottom end of the shell breaking mechanism, a second rocking bar rotationally connected with the second rotating shaft and a power shaft rotationally connected with the other end of the second rocking bar; and each power connecting shaft is connected with the top end of the interior of the shell by a fixed shaft. The device can increase the seed hull breaking speed and greatly reduce the damage rate of seeds in hull breaking, and is suitable for being widely popularized.
Description
technical field [0001] The invention relates to the technical field of alfalfa seed cultivation and treatment, in particular to a device and method for increasing the germination rate of alfalfa under continuous cropping. Background technique [0002] Alfalfa perennial herb, 30-100 cm tall. The roots are strong, deep into the soil layer, and the root neck is well developed. The stems are erect, clustered or even recumbent, quadrangular, glabrous or slightly pilose, with lush branches and leaves. Pinnate three compound leaves; stipules large, ovate-lanceolate, apex acute, base entire or with 1-2 tooth clefts, veins clear; petiole shorter than leaflets; leaflets long ovate, oblong ovate To linear ovate, equal in size, or slightly larger in terminal leaflet, (5)10-25(-40) mm long, 3-10 mm wide, papery, apex obtusely rounded, with long teeth protruding from midrib Pointy, base narrow, cuneate, margin more than one-third serrate, glabrous above, dark green, appressed pilose be...
