Usually in rural areas, rural families who go out to work will sublet their cultivated land to others for contract management. Extensive agriculture (such as feed) will be planted in farmland with great agricultural difficulty. Idleness caused by the bankruptcy of the contractor during the contract period will also be leased by the contractor (to reduce losses). Rural families without labor force will choose to plant fruit trees (long cycle, less physical labor), so there is a phenomenon of abandonment, but the abandonment time will not be too long.
The first effect: it is difficult to grow weeds because of the circulation of grass seeds in the later stage.
The farmers' farmland in our village has been abandoned for three years, overgrown with weeds, which is higher than people's height and has become the habitat of pheasants and wild birds. The villagers joked that "weeds grow better than crops". This kind of wasteland will be abandoned for a longer time, because the time span spans a whole year and grass seeds are scattered on the weeds, so it will be wasted more and more. Experienced old farmers say that it is difficult to cultivate in the later stage, and it takes time to remove weeds and grass seeds, at least one year.
The second function: to improve soil fertility.
Some people think that long-term abandonment will lead to the decline of soil fertility, but in fact, on the contrary, farmland has been fully conditioned, because long-term non-cultivation, weeds, soil will not harden, and the ability to store fertilizer and water will be enhanced; The circulating weeds will naturally decompose and increase the content of organic matter in the soil. The cleared abandoned farmland does not need too much chemical fertilizer supply, and it can also have a good output in the first two years.
Abandoning soil is a long-term abandonment behavior. The "fallow" caused by abandoned farming will really make the farmland fully recuperate and improve the later farming efficiency; However, long-term abandonment of farming will directly lead to difficulties in later farming; The worst impact is that long-term abandonment is likely to lose the right to contracted management of land, lose various economic subsidies and be punished.
