Device and method for increasing germination rate of alfalfa under continuous cropping

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...

AI Technical Summary

Problems solved by technology

[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 hardening problem, which makes the alfalfa seeds difficult to absorb water and have difficulty in aerobic respiration. After sowing, there will be low germination rate or no germination phenomenon, resulting in lack of seedlings and broken ridges, reducing the yield of pasture, seriously affecting the utilization of alfalfa seeds in the same year, and seriously affecting the planting and production of alfalfa. Therefore, between seed cultivation, it is necessary to Peel the seeds first

[0004] The current shell breaking machine uses a drum type or a stirring fan blade to break the shell. This method is easy to damage the alfalfa seeds, resulting in damage to the seeds that could have germinated
