Description

Technical Field

[0001] The invention relates to the technical field of corn planting, and in particular to a corn seed cultivation device. Background Art

[0002] Corn has strong resistance to drought, cold and barrenness, and has excellent environmental adaptability. As one of China's main food crops, corn is an important source of feed for animal husbandry, breeding, aquaculture, etc. It is also one of the indispensable raw materials for food, medical care, light industry, chemical industry, etc.

[0003] The quality of corn seed cultivation technology is a key factor in corn yield. Cultivating corn seeds requires the use of corresponding cultivation equipment to allow the seeds to germinate first and then plant them in the land. However, in order to promote the rapid germination of corn seeds, it is necessary to break the dormancy period of corn seeds. The hard shell of corn seeds is the main reason why corn seeds are in a dormant period. Therefore, in the prior art, water treatment, chemical treatment and steam germination are usually used. The water treatment method is a simple method, that is, soaking corn seeds in water for about 2 to 3 days, and changing the water once a day, which helps to break the dormancy period of seeds. This germination method germinates unevenly, has low efficiency, and a long corn seed cultivation cycle; the chemical treatment method uses chemical substances to open the seed coat and promote seed germination. The commonly used method is to soak corn seeds in a chemical substance called auxin. Auxin is a plant hormone that has a great effect on promoting seed germination and growth. The water vapor germination method has a good effect and can greatly promote the germination of seeds, but it is easy to cause chemical pollution; the water vapor germination method can provide a moist environment for seeds, promote the growth and development of seeds, ensure that seeds can germinate smoothly after absorbing enough water, increase the nutrient absorption capacity of seeds, improve the disease resistance and stress resistance of seeds, and make corn grow more healthily. It is a corn germination method that can shorten the corn seed cultivation cycle and is environmentally friendly. However, when the existing water vapor germination and cultivation device is used, the water vapor contacts the corn seeds unevenly, and the temperature gradient is large, so that the corn seeds in different positions are in contact with different temperatures, which leads to uneven germination and uneven germination, which seriously affects the germination quality of corn seeds by water vapor.

[0029] Specifically, a water inlet pipe is arranged at the top of the liquid storage tank 2, and a water outlet pipe is arranged at the bottom, and drain valves are arranged on both the water inlet pipe and the water outlet pipe.

[0030] Specifically, the diameter of the air holes 5 is smaller than the diameter of the corn seeds.

[0031] During specific use, the heating device 3 heats the pure water in the liquid storage tank 2, and the pure water generates water vapor when heated. The reciprocating push-pull rod 12 drives the germination groove 4 to make reciprocating linear motion in the germination box 1. The corn seeds entering the drum 9 move to the other end of the drum 9 under the conveying action of the spiral conveyor belt 32.
