Description
Technical Field
The invention relates to an agriculture and forestry plant protection technology, in particular to a method and a device for killing weeds by utilizing a heat energy high-temperature effect.
Background
The artificial ecosystem is established for a certain purpose by people and has superiority not possessed by a natural ecosystem, so that target plants in the farmland or forest and fruit lands flourish and comprise non-planting target plants, and measures for creating superior growth conditions include periodic land turning, soil loosening, fertilization, watering and the like to enable the target plants in the agricultural ecosystem to grow according to the wishes of people so as to meet the planting and harvesting targets of the people. However, weeds grow with crops, and since people carry out weeding operations in farmlands and forest and fruit lands for a long time, the vitality and adaptability of weeds are gradually strong, and various weeding measures of people are gradually adapted by adjusting self heredity and natural selection. Before the chemical herbicide appeared, people only can pull out weeds in an agricultural ecosystem by hands or remove weeds by a hoe, so that more light, heat, water, fertilizer and gas resources are utilized by cultivated plants. The weed species are various, even if the weeds of the same type are different, the growth and development progress is different, once weeding cannot be carried out, all weeds can not be completely removed, and more importantly, artificial weeding is carried out, the efficiency is very low, the weeds obtain stronger growth and propagation capacity than cultivated plants through the following ways, the weeds are prevented from being killed in farmlands by people, firstly, the seeds of the weeds form dormancy characteristics, the seeds are mature and fall into soil, the seeds do not germinate under proper conditions, the weeds have the after-ripening phenomenon, and the weeds can germinate after several years, so that the weeding difficulty is undoubtedly increased, and the weeds also have the risk of preventing the emergence of seedlings from sprouting once; weeds in the farmland have superior growth conditions, grow in one season, can generate a large amount of seeds, namely the propagation coefficient of the weeds is high, and the weeds are spread to a distance through burst, animal carrying, carrying and the like; thirdly, the maturation periods of the weed seeds are not consistent, so that the weed seeds are prevented from being eliminated by people at one time, and part of weeds can be seeded; and fourthly, weeding measures of people cannot be synchronized simultaneously, weeds in certain plots can seed at all times, and the weeds are spread by means of animal carrying and the like, so that the continuation of species is kept. The artificial weeding has the advantages that no harmful chemical substances are introduced into a farmland ecosystem, no environmental pollution is caused, and the artificial weeding is an important component content for the operation of ecological agriculture and organic agriculture.
After the chemical herbicide is released, the development of the world 'green revolution' is powerfully supported, the single yield and the total yield of food reach unprecedented historical levels, and simultaneously, the world population also reaches unprecedented quantity, and a scene of prosperity is created. Chemical herbicides achieve the purpose of killing weeds by inhibiting or blocking a certain metabolic process of organisms, such as glyphosate ammonium salt (trade name of Nondada) is absorbed and conducted to all organs in plants, nitrogen metabolism is blocked, and the plants die, so that the chemical herbicides have the reputation of killing the weeds when seen green. The use of chemical herbicide in large amount can control the weed, but the problem of environmental pollution is that the residual pesticide is transferred to grains, fruits and meat through food chain, and the biological accumulation and amplification effect exists, thus seriously threatening the health of human beings. When the chemical herbicide is used for killing weeds, the weeds can resist and tolerate sooner or later. One has to find new chemical herbicides that kill weeds from the millions of compounds, a process that is only a little simpler than that of looking for antimalarial drugs in yoyo.
The weeds and the seeds are biological organisms, contain water, organic matters, inorganic salts and the like, have specific tissue structures, have no resistance to high-temperature laser beams or focused sunlight regardless of structures in any forms, instantaneously evaporate the water in the bodies of the weeds to destroy conveying channels of the water and nutrients, properly cooperate weeding strategies, and kill the weeds and the seeds on the ground surface by using the heat energy high-temperature effect, so that the weeds cannot generate resistance and tolerance. If the ammonium glyphosate has the reputation of killing when seeing green, the living things encountered in the farmland can be killed without any consideration by the scanning of the high-temperature laser beam and the focused sunlight, the purification of the farmland ecosystem can be realized, only the effect of crop growth is allowed, and the farmland ecosystem is not polluted, so that the technology is environment-friendly and can be developed and utilized continuously.
