Why is it not allowed to grow corn beside rural roads in Guizhou?

First of all, Guizhou's topography is complex and changeable, and there are many agricultural areas. It is more suitable for developing tourism and characteristic agriculture. Although it can also grow corn, it is difficult for large agricultural machinery to operate here. This means that farmers have to do a lot of work by themselves. Doing so will increase a lot of labor costs, and most of the corn planted by farmers is used for their own consumption, and there is no surplus, which is not conducive to their poverty alleviation.

Planting corn is also not conducive to soil and water conservation. The root system of corn must be shallow, and its ability of soil and water conservation is poor. When it rains, the soil and water will be washed away seriously. Long-term damage to the ecological environment is great, and Guizhou is not suitable for planting corn. Planting corn in suitable areas, in some rainy areas with relatively high humidity, farmers can't dry corn in time after harvest, which leads to mold in corn. At this time, it is not only a waste of food, but also easy to get sick after eating it.

In recent years, China's corn planting area is too large, resulting in low corn prices and overproduction. At present, the purchase price of corn kernels in many parts of the country is mostly around 7 cents per catty. This price has been greatly discounted compared with the previous two years.

Therefore, the state began to make adjustments to encourage and subsidize farmers to replant some crops with good economic benefits, such as fruits, vegetables and Chinese medicine. These crops can not only keep water and soil, but also bring good economic benefits. In the future, they will certainly bring considerable income to local farmers.

Relevant departments have also made clear the adjustment of maize planting in Guizhou: maize is not planted, but planted well and well, which is the way to develop agriculture efficiently in modern mountainous areas. Another key point is that farmers' crop sales should be deployed in advance because they are guided to optimize planting. Once the harvest season comes, crops should be replanted. The yield of crops is not as good as that of corn, which may have the opposite effect. Environmental protection is a matter for the whole society, not just for farmers.
