Agricultural products have their own production characteristics and product attributes, and the quality of similar agricultural products produced in different producing areas is different. In addition, the production technology in different producing areas is different, and there are also great differences between farmers and farmers in planting and field management. All these lead to different product characteristics of different producers, and even uneven product quality. In addition, the lack of unified product sorting standards leads to a low degree of standardization of online agricultural products at this stage. At present, it is really difficult to achieve unified and standardized production in many places because of the agricultural products management of one household in China and the geographical environment in some mountainous areas.

Standardization of agricultural products, some for the convenience of consumers to identify product quality, but more for the needs of mass production, packaging and logistics. However, most consumers don't care whether the shape of agricultural products is square or round, whether the size is consistent, and whether the packaging is exquisite, but want to know the taste and sweetness, and whether the products can be obtained with good quality and quantity.

The reality is that the domestic wheat supply exceeds demand, and the inventory pressure is great. International wheat prices, especially those in major grain-producing countries such as the United States, are very low, directly forcing domestic prices to remain low. The low food prices in the United States and other countries are directly related to the large scale of mechanized production, high production efficiency and low labor costs. Compared with China, even though large-scale operation has been vigorously promoted in recent years, the fragmented operation of one household is still the main body of agricultural operation, with high investment and management costs, and the aging of agricultural population leads to high relative cost of agriculture.

Bread is the pillar of life. Agricultural products, as necessities of life, have always had rigid demand, and the sharp drop in prices has caused difficulties to the basic life of low-and middle-income groups, which may lead to social unrest or even unrest. For example, on 20 16, the price of grain fell, and the average income per mu fell, which had a relatively adverse impact on operational income, a peasant family. At the same time, the decline in grain income will also affect the enthusiasm of growing grain and bring hidden dangers to national food security.

The reasons for "slow sales" are very complicated, but the main reasons are as follows: First, the market demand is underestimated, and blind planting may lead to oversupply, only planting and ignoring market sales. Second, the lack of organized cooperative management, once unsalable, farmers must bear the risk alone. Third, some people have speculative psychology, and they are eager for some agricultural products with higher profits, planting them last year to make money, so as to form a situation of "rushing headlong into it". Fourth, some people speculate on some agricultural products, and "hoarding" speculation is also a reason to promote unsalable sales.
