Description
Technical Field
The invention relates to the technical field of agricultural production, in particular to a circular agricultural production method.
Background
Agricultural production refers to the production activities of planting crops. Including the production of crops such as grains, cotton, oil, hemp, silk, tea, sugar, vegetables, tobacco, fruits, medicines, miscellaneous crops (other commercial crops, green manure crops, breeding crops and other crops), the growth and propagation of animals and plants are closely related to natural conditions, so that the animals and plants (or plant seeds) and the natural conditions such as heat, light, water, terrain, soil and the like become necessary investment for agriculture. On the basis of these investments, agriculture can obtain output through the labor of workers (i.e., investing labor). With the development of social productivity and the improvement of economic level, the input proportion of production data is gradually increased in agricultural production. The agricultural machine replaces manual farm tools, so that the labor force is liberated, and the labor productivity is improved; the input of chemical fertilizers, pesticides and the like can promote the output of agriculture. In modern agriculture, increasing scientific and technological investment (such as cultivating improved varieties, improving irrigation technology, improving working modes and the like) becomes an important means for improving agricultural output.
At present, agricultural workers in the first line from basic governments and agricultural departments to rural basic cadres and production still hold extensive and traditional agricultural operation concepts, the cyclic economy is not well known, even the basic knowledge is not known at all, so that many cyclic agricultural scientific and technological achievements cannot be directly converted into practical productivity through farmers, and the cyclic agricultural scientific and technological progress of China is severely restricted. The technology with obvious application effect in the annual agricultural scientific and technological achievement in China is less than 5 percent. Taking a chemical fertilizer as an example, because farmers do not pay attention to the concentration, the fertilizing period and the fertilizing method of the chemical fertilizer when using the chemical fertilizer, the utilization rate of the chemical fertilizer in China is only 30% -40%, but developed countries reach 60%, and nearly 3000 million tons of the chemical fertilizer are wasted every year.
