Amphibious cultivation method

Abstract

The invention relates to an amphibious cultivation method, which comprises the following steps of: ridging a dry field; dibbling seeds; fertilizing under the seeds; and managing the water slurry to prevent the flooding time from continuously exceeding a preset value. According to the amphibious cultivation method, the traditional water cultivation can be improved into a amphibious cultivation, thedry field ridging is easy to realize mechanized scale operation, the seeds dibbling and fertilizing all can be realized in a mechanized mode; on the one hand, the production efficiency is improved, on the other hand, the problem that the rice yield is influenced by long-term flooding to form a commonly known as 'green mud layer' is avoided; on the one hand, the desertification degree is improved,and on the other hand, the soil aeration can be improved; furthermore, the heavy metal elements are transferred from soil minerals, which can weaken the adsorption of heavy metal elements by the soilmineral particles and realize the dispersion of the heavy metal elements to the depth of the soil layer, so that the heavy metal elements are deposited to the depth of the soil layer to realize the transfer of treatment targets. The amphibious cultivation method solves the problem of excessive heavy metals caused by heavy metals accumulation, which ensures the food safety of crops.

Description

Technical field [0001] This application relates to the field of planting, especially to the method of amphibious planting. Background technique [0002] The biothermodynamic theory of soil fertility is a major theoretical discovery of epoch-making significance founded by Hou Guangjiong. The theory is inclusive and has a wide range of applications. It is used in natural no-tillage technology in paddy fields, water and soil conservation, agricultural non-point source pollution control, soil fertilization and Formulated fertilization technology has a positive guiding role. The theory of soil fertility biothermodynamics was sublimated by Mr. Hou Guangjiong on the basis of the practical experience of farmers’ production. It has not only received great attention and wide praise from the soil science community at home and abroad, but also won the national major scientific and technological achievements of the National Science Conference in 1978. prize. The theory of soil fertility bio...

Problems solved by technology

Since the previous ridging method was manual ridging under the condition of thin mud field, usually the complete set of traditional hydroponic water raking process was completed first, and then manual ridging was used. Sometimes it took 15 labor days to rid one mu of field , if it takes too little labor, the effect will be greatly reduced
