Technology of Straw Burying and Returning to Field in Facility Cultivation

Abstract

The invention discloses a straw burying, pressing and returning technology in facility cultivation. Old plants pulled out during crop alternation, and old leaves, flowers and fruits removed during daily management in facility cultivation are buried and pressed through soil in a facility to be isolated from air, meanwhile, high-temperature greenhouse heating is carried out, plant residues are in the high-temperature anoxic small environment, pathogenic bacteria on crops are killed, and the vicious circle that plant residues with bacteria are stacked everywhere to cause environmental pollution and bacteria are produced is avoided; meanwhile, the plant residues are rotten by being buried and pressed, plowing can be directly carried out for straw returning, and efficient organic fertilizer is provided for soil.

Description

technical field [0001] The invention relates to the technical field of facility cultivation, more specifically, the invention relates to a technique of burying and pressing straw on the spot in combination with a high-temperature braising shed in facility cultivation, so as to kill pathogenic bacteria on the straw and return the straw to the field. Background technique [0002] For a long time, in protected cultivation, the old leaves removed by management at ordinary times, the flowers and fruits removed by thinning, and the old seedlings pulled out when changing stubble were all removed outside the facility. These cleaned up large quantities of plant residues contain various germs and are piled up around the facility. In rainy and high-humidity weather, the germs multiply rapidly and continue to be released and spread in the surrounding environment of the facility, causing various diseases in the facility. Diseases continue to occur, and at the same time, a large number of...

Problems solved by technology

These cleaned up large quantities of plant residues contain various germs and are piled up around the facility. In rainy and high-humidity weather, the germs multiply rapidly and continue to be released and spread in the surrounding environment of the facility, causing various diseases in the facility. Diseases continue to occur, and at the same time, a large number of plant residues are piled up, which damages the surrounding environmental sanitation, causes environmental pollution, and affects the appearance of the environment

[0003] On the other hand, because these cleared leaves, flowers and fruits and old seedlings often contain multiple pathogens, there is no report of returning them to the field as organic fertilizers at present. Therefore, while these plant residues destroy and pollute the environment, they also waste of material
