Description

Plant seed stimulation treatment device and system

Technical field

The invention relates to the technical field of plant planting seed treatment equipment, in particular to a plant seed stimulation processing device and system.

Background technique

The current global population is over 7 billion, and the population will grow rapidly to 9 billion in the near future. By then, there will be a gap of about 10% in land and arable land and food demand. One way to solve the current predicament is to increase food production. At present, the ways to increase production include breeding hybrid planting or mutation planting of genetically modified seeds to improve disease resistance, etc.; or use of fertilizers, especially chemical fertilizers, auxins, and insecticides. At present, the scientific community and the health sector are paying attention to the negative impacts of pesticide residues, chemical residues and other factors, and the attention is getting higher and higher.

Rice is one of the three major food crops in the world. The planting area accounts for 1/5 of the grain sown area, and the annual output is about 480 million tons, accounting for 1/4 of the world's total grain output. More than half of the world's grain. The population is mainly rice. Rice is also one of the most important cultivated crops in China, accounting for 1/2 of the country's food production. Therefore, the advancement of rice production technology is of great significance for improving food security in China and the world. As an important environmental stress, ultrasonic has been actively promoted in promoting the increase of horticultural crops and improving the growth and growth of crop seeds. Ren Xing'an (1993) and Yang Bo (Department of Electrical Engineering, Shaanxi University of Technology, Hanzhong, Shaanxi 723003, China), "Preliminary Study on the Application of Ultrasound" published in the 7th issue of Volkswagen Science and Technology, 2006, explored the effects of ultrasound on rice growth and yield increase; The effects of ultrasound on rice growth and yield have also been discussed. Previous studies have found that ultrasound has a certain degree of yield increase effect on rice seed treatment, but the effect is not stable, and the yield is increased under one ultrasonic treatment condition and the yield is reduced under another treatment condition. This is because the effect of ultrasonic treatment on seeds is closely related to the design of rice seed pretreatment technology and ultrasonic parameters. The effect of any part on seed biochemistry and metabolic application of poor energy will lead to completely opposite disadvantages, especially Leading the technology to Daejeon for large-scale processing and stable production increase is even more Breaking the technological revolution.

The existing ultrasonic treatment planting equipment, especially the dry processing device, must solve the problem of large-scale treatment of seeds, so that the system can ensure that the seeds can uniformly receive the two stable effects of irradiation, and the control processing time is consistent and repeatable, and the strict compliance meets the seeds. The activation of the increase in production produces functional conditions, and it is possible to control the multi-band and continuous or pulse, moderately temperate and other multi-directional integrated technologies to achieve the effect of increasing production. The seeds are generally moved from the high point into the ultrasonic treatment pipeline for ultrasonic irradiation treatment. The plant seeds cannot be completely and uniformly contacted with the inner wall of the ultrasonic treatment pipeline, and the ultrasonic treatment effect is relatively poor, and the increase in yield cannot be achieved at the highest.
