Intercropping method of wheat, spring onion and Platycodon grandiflorum for disaster prevention and mitigation

Abstract

The invention discloses a wheat, shallot and platycodon grandiflorum intercropping method for preventing and reducing disasters. The method includes detailed steps that in autumn of the current year, planting is performed in the mode of wheat-shallow-platycodon grandiflorum intercropping; in summer of the second year, matured winter wheat is harvested, primarily formed shallot seedlings and platycodon grandiflorum seedlings are pulled out and then transplanted to close-end borders after a field is prepared; in autumn of the second year, shallots and one-year platycodon grandiflorum are harvested, and then planting is performed in the mode of platycodon grandiflorum-wheat-shallot intercropping; in summer of the third year, wheat and transplanted primarily formed shallot seedlings and platycodon grandiflorum seedlings are harvested, and the transplanting sequence is shallot-shallot-platycodon grandiflorum-platycodon grandiflorum-shallot-shallot-platycodon grandiflorum-platycodon grandiflorum and so one; in autumn of the third year, shallots and platycodon grandiflorum are harvested, and then cyclic rotation starts to be performed. With the method, the problem that because farmers only grow grains, benefits are low, namely, it is guaranteed that the farmers can eat the grains, and certain economic income is obtained.

Description

technical field [0001] The invention relates to crop cultivation techniques. Background technique [0002] At present, the global climate is experiencing significant changes characterized by warming, with the global surface temperature rising by 0.85°C between 1880 and 2012. Climate change induces changes in the atmosphere, hydrology, soil, and biological processes on the Earth's surface, and will continue to have significant impacts on natural and socioeconomic systems. Climate warming leads to changes in phenological periods and affects agricultural production. For example, North China is an important grain production area. The main crops are wheat and corn. It is often affected by the monsoon climate, with spring drought and summer flood. Especially in the last ten days of May every year, high temperature weather above 35°C often occurs, causing dry and hot wind, causing a certain yield loss of winter wheat. At present, the conditions for forming winter wheat dry and h...
