RiceIt is an important food crop in China, ensuring the food supply of 1.4 billion people in China. However, despite the fact that we areHybrid riceMajor breakthroughs have been made in the research and development of technology, but in the United StatesRiceThe yield per mu is 204 catties higher than that of China. Why in two countries with the same seeds, the United StatesRiceWhy is the yield so high? This article will analyze the differences in planting areas, planting methods, and climatic factors.
China has vast land resources, but due to its large population, it hasArea of cultivated landLimited. RiceThe planting is mainly concentrated in mountainous and hilly areas, and the land fertility in these areas is generally low, with an average yield of about 370 catties per mu. In contrast, the United StatesRiceThe planting area is mainly located in the plains andLakesAround, the land is fertile and the yield per mu is relatively high.
Adopted with ChinaFamily farmsSmall-scale cultivation is different from that of the United StatesRiceCultivation is more specialized and industrialized. U.S. farmers use high-tech equipment for planting, for exampleRice transplanter, improve the production efficiency and yield per mu. And the Chinese oneFarmersNow there is a general reluctance to engage in itAgriculturelabor, which led to the desolation of a lot of arable land, affectedRiceYield.
The number of harvests of a crop has a direct impact on yield. In northern China, due to climatic conditions,RicePlanting is usually only one or at most two harvests. In contrast, the southern region has a warm climate and can harvest two or even three cropsRice, the yield per mu is relatively high. AmericanRiceMost of the planting areas are in the ** zoneEvergreen broad-leaved forestThe climate, with high temperature and rain in summer and mild and little rain in winter, is very suitableRicegrows, so that it is able to harvest multiple seasonsRice, guaranteeing a high yield.
RiceAs a crop that consumes a lot of water, it has a high demand for abundant water resources. China's main oneRiceThe planting area is mostly the first with monsoon climate, high temperature and rainy summer, thereforeRiceWater resources for cultivation are relatively abundant. And the growing areas of the United States rely more onLakesand other water sources for irrigation, guaranteedRiceThe water requirement of the planting, so that the yield per mu is relatively high.

Despite the AmericanRiceThe yield per mu is higher than that of China, but China as a country with a large populationRiceTotal production is still higher than in the United States.
