Environment-friendly ecological circulation potato planting system

Abstract

An environment-friendly ecological circulation potato planting system is formed by combining sweet potato planting, cattle breeding and a biogas system. Sweet potatoes obtained through sweet potato planting can be directly sold on the market, and other products can also be obtained through deep processing and sold on the market; sweet potato vines obtained in sweet potato planting and sweet potato residues obtained in sweet potato processing can be used as feed for feeding cattle; the biogas system is built underground in a livestock farm during cattle breeding, excrement generated in the cattle breeding process can be directly discharged into the biogas system, waste generated by sweet potato processing can also be discharged into the biogas system, and finished product cattle obtained through cattle breeding are put into the market. The biogas system is used for generating electricity, pest killing lamps are arranged in the sweet potato planting field to eliminate mosquitoes during sweet potato planting, and biogas residues generated by the biogas system are directly returned to the field to serve as an organic fertilizer for sweet potato planting. According to the system, the sweet potato planting, cattle breeding and the biogas system are organically combined, and an organic virtuous cycle is integrally formed.

Description

technical field [0001] The invention relates to the fields of agricultural planting and animal husbandry, in particular to an environment-friendly ecological cycle potato planting system. Background technique [0002] In my country, sweet potato is a very important raw material for food processing, and its cultivation is also very common. In the current cultivation of sweet potato, in order to ensure the yield of sweet potato, fertilization and spraying of pesticides are commonly used means, but this has caused damage to the ecosystem. It has affected the quality of sweet potatoes and does not meet the requirements of national environmental protection management. And the harvest of sweet potatoes only collects the tubers, but the stems and leaves of sweet potatoes are often discarded and not fully utilized, resulting in waste and polluting the environment. Cattle breeding is also one of the main animal husbandry industries in my country. When feeding cattle, due to the high ...

[0002] In my country, sweet potato is a very important raw material for food processing, and its planting is also very common. In the cultivation of sweet potato, in order to ensure the yield of sweet potato, fertilization and spraying pesticides are commonly used means, but this has caused damage to the ecosystem. It affects the quality of sweet potatoes and does not meet the requirements of national environmental protection management

Moreover, only the tubers are harvested from sweet potatoes, but the stems and leaves of sweet potatoes are often discarded and not fully utilized, resulting in waste and polluting the environment

Cattle breeding is also one of the main animal husbandry industries in my country. When feeding cattle, due to the high cost of fodder, feed is often added for feeding. At present, feed contains various additives, which undoubtedly affects the quality of beef, and in the breeding process The cow dung produced in the factory has not been properly and effectively treated, causing great pollution to the environment
