Seed dormancy breaking device

Abstract

The invention discloses a seed dormancy breaking device, and relates to the technical field of agricultural machinery. The device comprises a bottom plate, a lead screw lifting adjusting mechanism, aninclined supporting mechanism, a gastric juice containing barrel, a seed storage barrel and a stirring motor, the lead screw lifting adjusting mechanism is installed on the rear portion of the upperportion of the bottom plate, and a sliding plate is installed at the front end of the lead screw lifting adjusting mechanism. Through arrangement of the gastric juice containing barrel, the seed storage barrel and the stirring motor, seeds to be subjected to dormancy breaking are placed in the gastric juice containing barrel, cattle and sheep gastric juice is added into the gastric juice containing barrel outside the seed storage barrel, the cattle and sheep gastric juice is immersed into the seeds, and the seeds are driven by the stirring motor to roll up and down in the cattle and sheep gastric juice to simulate cattle and sheep gastric movement to digest food; the strong acidity of cattle and sheep gastric juice is used for promoting seed coat decomposition, so that the effect of breaking dormancy of seeds is achieved, and the problems that an existing seed dormancy breaking mode is poor in dormancy breaking effect and high in seed damage rate and does not conform to the green and environment-friendly concept are solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a seed breaking device. Background technique [0002] Seed dormancy refers to the phenomenon that viable seeds cannot germinate normally under appropriate temperature and humidity conditions. The types of herbaceous plant dormancy include dormancy caused by inhibitory substances, embryo dormancy, dormancy caused by seed (fruit) skin, comprehensive dormancy and It is not suitable for secondary dormancy caused by external conditions. Seed dormancy mechanism is the result of plants in natural selection. Seed dormancy is a self-protection mechanism produced by plant seeds to resist adverse factors in survival. Because the seeds can quickly germinate in the soil after sowing, the existing methods for desomnancing the seeds mainly include mechanical dermabrasion and chemical reagents to promote germination. Those who use potassium nitrate, thiourea, ethylene hydrogen c...

Problems solved by technology

[0003] The purpose of the present invention is to provide a device for breaking sleep of seeds. By setting a gastric juice storage tube, a seed storage tube and a stirring motor, the seeds to be broken sleep are placed in the gastric juice storage tube, and cattle and sheep are added to the gastric juice storage tubes other than the seed storage tube. Gastric juice immerses the gastric juice of cattle and sheep into the seeds, uses the stirring motor to drive the seeds to roll up and down in the gastric juice of cattle and sheep, imitates the digestion of food in the stomach of cattle and sheep, and uses the strong acidity of the gastric juice of cattle and sheep to promote the decomposition of the seed skin, so as to achieve The effect of seed breaking sleep solves the problem that the existing seed breaking effect is poor, the seed damage rate is high, and it does not conform to the concept of green environmental protection.
