Grinding disc type hard seed dormancy breaking production system

Abstract

The invention discloses a grinding disc type hard seed dormancy breaking production system. The grinding disc type hard seed dormancy breaking production system comprises a dormancy breaking agent box(1), a grinding disc type hard seed mechanical-breaking machine (2), a seed filtering device (3), a grinding disc type drying device (4), a conveying device (5) and a constant temperature incubator (6) which are connected in sequence. The grinding disc type hard seed dormancy breaking production system is reasonable in structure design, convenient to operate, high in automation degree and good incomplete set nature. By adopting the chemical dormancy breaking and mechanical dormancy breaking joint mode and integrating the filtering device, the drying device and the constant temperature incubator, the efficiency of breaking shells of hard seeds such as alfalfa seeds is high, cultured seeds can be directly planted after being taken out, the seeds are easier to sprout, the germination rate of the hard seeds is greatly improved, and the grinding disc type hard seed dormancy breaking production system has an important application value.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a disc-type hard seed breaking dormancy production system. 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. The mechanism of seed dormancy is the result of natural selection in plants. Seed dormancy is a self-protection mechanism produced by plant seeds against adverse factors during survival, so the seeds of many plants have dormancy characteristics. Bask's research in 1998 showed that among the plant seeds around the world, the plant types that exist or exhibit seed dormancy characteristics account for the vast majority, and t...

AI Technical Summary

Problems solved by technology

[0003] In the central and western regions of my country, due to the impact of severe climate, seeds have been affected by extreme weather (such as high cold and drought) for a long time, which has aggravated the problem of seed dormancy, and caused the reduction of production due to seed dormancy when large-scale seed application is carried out. Serious impact

[0004] At the same time, under the environment of the country's further promotion of returning farmland to forest and returning farmland to grassland, there is a demand for a large number of forest and grass seeds. However, due to the dormant problem of seeds in the large-scale seed demand, the output will not be able to reach The problem of the expected goal, the second replanting is facing the situation that the cost is uncontrollable

Existing sleep-breaking methods are limited to a single sleep-breaking method, and existing sleep-breaking methods have problems such as low efficiency, poor pollution, and unsuitability for large-scale batch processing.
