The "quantity" of grain production should be increased, and the grain production should be "high quality".

China's grain production has enjoyed "11 consecutive increases" this year, which is a good achievement against the backdrop of China's declining economic growth.

We should also be pleased to see that although the output continues to increase, compared with developed countries, China's grain production still can not get rid of the extensive production mode of relying on chemical fertilizers, pesticides and flood irrigation to increase production. At present, the average amount of chemical fertilizer per mu in China is 21.2 kg, 4.1 times the world average, and the average utilization rate of chemical fertilizer is about 30%, 20 percentage points lower than that of developed countries. Grain production shows the obvious characteristics of "big farmers, big water, big fertilizer".

There is a lot of chemical fertilizer input, but the utilization rate is low year after year, which is easy to cause soil consolidation and lead to the decline of cultivated land quality. At present, the average content of soil organic matter in cultivated land in China is only 1.8%, which is 0.35% lower than that in the early 1990s. Even the most fertile black land in the northeast has only 2.9 per cent of organic matter, 1 percentage point lower than in the 1980s. The extensive farming mode not only overdraws the soil fertility and production capacity, but also easily leads to farmland pollution and safety problems such as excessive heavy metals in agricultural products.

China's annual grain output has stood steadily above the trillion jin mark for seven consecutive years, and in the future, while ensuring the stability of the total amount, we should pay more attention to the improvement of grain quality, and achieve "quality" quality while increasing "quantity".

One of the keys to "high quality" is to pay more attention to the quality and efficiency of grain production, rely on good laws and varieties, and vigorously increase the contribution rate of science and technology in grain production. The experience of developed countries shows that when a country's per capita GDP reaches the stage of US $80, 000 to US $10, 000, the input of chemical fertilizers and pesticides in the process of grain cultivation will decrease rather than increase. At present, China is moving towards this stage, and it is very important to abandon "big farmers, floods, and fertilizers" and let science and technology become the main force in the improvement of grain yield per unit area. Last year, the contribution rate of China's agricultural scientific and technological progress reached 55.2%, which is still significantly lower than that of Germany, Britain and France, which is more than 90%. There is still plenty of room for science and technology to promote grain production.

The most intuitive embodiment of "quality" is to pay more attention to the quality of agricultural products. With the improvement of China's agricultural productivity and the transformation of consumption structure, the relationship between supply and demand of agricultural products in China has gradually changed from seller's market to buyer's market. After meeting the basic needs of food and clothing, people pay more and more attention to "safety on the tip of the tongue" and "delicacy on the tip of the tongue". We should not only eat well, but also eat healthily. In the face of this change in demand, only by shifting agricultural production from quantity to equal emphasis on quantity and quality can we better serve the masses and promote the healthy development of agriculture.
