In order to fully ensure the safety of food and important non-staple food supply, the General Office of the Ministry of Agriculture and Rural Affairs recently issued the "Plan for Scientific Disaster Resilience and Stable Production and Supply Guaranteeing for La Niña This Winter and Next Spring" (hereinafter referred to as the "Plan").
La Niña could trigger extreme cold, causing frost damage to crops
La Niña refers to the abnormal cooling of waters in the central and eastern Pacific Ocean
Since July this year, the SST in the equatorial central and eastern Pacific has continued to decline.
In China, La Niña is mainly manifested as "cold in winter and hot in summer" and "flood in the north and drought in the south"
Generally speaking, when La Niña occurs, the temperature in our country is relatively low
When La Niña strikes our country, there will also be widespread cooling and strong winds.
Mainly affects wheat, weak correlation with corn and rice
The La Niña Index (ONI) has a strong correlation with the domestic agricultural product price index
Since 1950, there have been 5 double La Niñas in the history of our country
Soybean cultivation is an important area affected by La Niña weather
The direct correlation between La Niña and China's corn price is not strong
From the historical data, the La Niña index and China's wheat price index show a strong correlation, mainly because La Niña has a greater impact on winter crops
La Niña has no obvious effect on rice production and price, and the correlation is weak
According to industry insiders, except that the price of wheat is greatly affected by La Niña, the correlation between the prices of corn and rice and La Niña is limited, and their price trends are mainly based on their own fundamentals and supply and demand
"In early and mid-November, the cold air from the north arrived earlier than in previous years, and extreme weather may delay the production of agricultural products.
Jiang Zhenfei believes that, on the whole, cold air has different effects on the growth, planting and yield of different agricultural products, but the impact is short-lived
