Some people say that fallow is due to overproduction in our country, which is true, but it is still inappropriate.

In 2017, the fallow area of our country is 2 million mu, and the rotation area is 10 million mu, which is still far from the target of 50 million mu. Rotation and fallow has two meanings: rotation is to replace the crops planted in the previous crop with other crops, while fallow is to stop farming for a period of time.

To answer the question of whether crop rotation and fallow means grain surplus in our country, we must first understand the background of rotation fallow proposed by the state.

It is true that crop rotation and fallow will have a certain impact on China's grain production, but with the emergence of a series of problems in recent years, such as soil destruction, lower fertility, depletion of groundwater resources and so on, the contradiction between production and environment is becoming more and more prominent, that is to say, if this continues, the agricultural production capacity of arable land in China will become weaker and weaker in the future, that is, it will not have sustainable development. At present, there is a flood of chemical fertilizer application in farmland in many areas, and soil fertility can be said to be consumed in advance.

In this context, the state proposes agricultural rotation fallow, so that farmland can be repaired and production capacity can be restored. At a meeting of the Ministry of Agriculture and villages, a leader also made a relevant statement on this issue, due to the implementation of crop rotation and fallow, although the annual quarterly output has declined, but the quarterly output has been greatly increased. In addition, the launch of crop rotation is not carried out in the field year after year, but by rotation. In order to ensure that the soil ecology should be improved in the lower fertility areas of the country.

Let's talk about the impact of crop rotation and fallow on yield. Under the background of successive years of grain destocking in our country, it also shows that China's grain supply is still relatively sufficient, while the scope of crop rotation and fallow has no impact on China's food security. In 2017, the output affected by crop rotation and fallow is about 8 billion jin, which is equivalent to 0.6% of China's total grain output, and the impact is very weak.

Through the above analysis, we should understand that the premise of crop rotation and fallow is that our country currently has enough grain to support the implementation of this strategy, but we should not think that the implementation of crop rotation and fallow means that China has an adequate food supply. To be exact, China's grain is only structurally sufficient. After all, China imported 95.53 million tons of soybeans last year.
