Taihu Plain, Poyang Lake Plain, Dongting Lake Plain, Jianghan Plain, Jianghuai Area, Chengdu Plain, Songnen Plain, Sanjiang Plain and Pearl River Delta.
Commodity grain base has the conditions.
① The conditions for grain production are good, the proportion of farmland with high and stable yield is significant, and there is more surplus grain.
(2) per capita possession of areas with large grain quantity, high commodity rate, great potential for increasing production, less investment and quick results.
③ Grain production is concentrated and contiguous, and the natural conditions and production conditions are basically similar, which is convenient for unified planning, construction and production layout.
(4) Taking grain production as the center, the contradiction between grain production land and cash crops and other crops production land is small, and the transportation is convenient.
classify
The first category is the original high-yield commodity grain base in the south, including the Yangtze River Delta, Jianghan Plain, Poyang Lake Plain, Dongting Lake Plain and Pearl River Delta. These bases have a large population, few fields, and are located in the subtropical zone, with superior natural conditions and long growth period of crops, which can be harvested in more than one year.
The second category, the newly developed commodity grain base in Huaihe Plain, including northern Jiangsu and northern Anhui, is located in the south of Huanghuaihai Plain, with flat terrain, deep soil layer and good groundwater conditions, and is in the transition zone from warm temperate zone to north subtropical zone. Precipitation, heat and frost-free period are lower than those in Jiangnan and higher than those in the north of the Yellow River, which is an important potential grain producing area in China.
The third category is the northeast commodity grain base with low level and the greatest development potential, including Sanjiang Plain, Songnen Plain, Central Jilin Plain and Central Liaoning Plain. Northeast China is vast and sparsely populated, with high latitude, and the heat conditions are not as good as those in the south, so it can only be harvested once a year. Production conditions and original foundation are not as good as the first two categories. Agricultural management is extensive and the level of grain yield per unit area is still low.
The fourth category is the commodity grain base in the arid area of northwest China, including Hexi Corridor, Inner Mongolia and Ningxia Hetao area. The annual precipitation is less than 250 mm, the climate is dry, the crop growth period is short, and only one crop can be harvested a year.

Songnen plain. Sanjiang plain. I suggest you go to Baidu to search for "commodity grain base", which has a map and specific location.
Nine commodity grain bases and five cotton bases
China agricultural production base mainly has nine commodity grain bases:
The three northeastern provinces have Sanjiang Plain and Songnen Plain; Chengdu Plain in Sichuan Basin; Pearl River Delta Plain, Jianghan Plain, Dongting Lake Plain, Poyang Lake Plain, Jianghuai Plain and Taihu Lake Plain.
In addition, Hetao Plain, Ningxia Plain, Hexi Corridor and Xinjiang Oasis are all grain production bases in China. Henan, Anhui, Jiangsu and other provinces are the major grain provinces in China.
Agricultural production base is a centralized production area that occupies a heavy position in the national or regional agricultural product economy and can provide a large number of agricultural products to the inside and outside of the region for a long time. Such as grain, oil, sugar, vegetables, animal husbandry, fisheries and other production bases.
Extended data:
Requirements of agricultural production base in the following aspects:
First, it emphasizes the specialization of production and the regionalization of planting, so as to make the base as contiguous as possible and form a scale.
Second, in the management of the base, pay attention to the organization and implementation of production technical regulations, and promote unified services such as agricultural materials supply and pest control.
Third, in terms of operation mode, actively explore the operation mechanism of base construction and management, promote the operation mode of "enterprise+base+farmer", "market+base+farmer" or "cooperative organization+base+farmer", and promote the virtuous circle of integrated development of base production, management and operation.

Names of Nine Commodity Grain Bases in China
; ? The nine commodity grain bases in China are Sanjiang Plain, Songnen Plain, Taihu Plain, Jianghuai Region, Jianghan Plain, Poyang Lake Plain, Dongting Lake Plain, Chengdu Plain and Pearl River Delta. Since 1983, China has invested144 billion yuan to build 274 national commodity grain base counties. These commodity grain base counties are not only concentrated in nine commodity grain bases, but also distributed in Inner Mongolia, Guangxi, Fujian, Qinghai, Xinjiang, Yunnan, Guizhou and other provinces. The construction of commodity grain base includes not only supporting projects of small water conservancy facilities, but also infrastructure construction and intellectual investment such as agricultural technology extension system and improved seed breeding system, so as to improve the comprehensive agricultural production capacity and enhance the stamina of agricultural development. During the ten years from 1983 to 1992, these commodity grain bases produced a total of 399.2 billion kilograms of grain, of which about half of the new grain output in China was produced by commodity grain bases.
