which two regions grow most of china’s rice
provinces along the Yangtze River provinces in the south
title: Rice production in China text: Rice production in China Rice production in China is an important part of the national economy. China is the world's largest producer of rice, and the crop makes up a little less than half of the country's total grain output. China accounts for 30% of all world rice production. In a given year total rice output came from four different crops. The early rice crop grows primarily in provinces along the Yangtze River and in provinces in the south; it is planted in February to April and harvested in June and July and contributes about 34 percent to total rice title: Rice production in China text: output. Intermediate and single-crop late rice grows in the southwest and along the Yangtze; it is planted in March to June and harvested in October and November and also contributed about 34 percent to total rice output in the 1980s. Double-crop late rice, planted after the early crop is reaped, is harvested in October to November and adds about 25 percent to total rice production. Rice grown in the north is planted from April to June and harvested from September to October; it contributes about 7 percent to total production. All rice cultivation is highly labour intensive. Rice is generally title: Rice production in China text: transportation systems combined to induce farmers to feed large quantities of lower quality rice to livestock.

Recently, with relative food security in China, periurban agriculture has led to improvements in the quality of the food available, as opposed to quantity. One of the more recent experiments in urban agriculture is the Modern Agricultural Science Demonstration Park in Xiaotangshan. About 75% of China's cultivated area is used for food crops. Rice is China's most important crop, raised on about 25% of the cultivated area. The majority of rice is grown south of the Huai River, in the Zhu Jiang delta, and in the Yunnan, Guizhou, and Sichuan provinces. Wheat is the title: Paddy field text: used for food crops. Rice is China's most important crop, raised on about 25% of the cultivated area. Most rice is grown south of the Huai River, in the Yangtze valley, the Zhu Jiang delta, and in Yunnan, Guizhou, and Sichuan provinces. Rice appears to have been used by the Early Neolithic populations of Lijiacun and Yunchanyan in China. Evidence of possible rice cultivation from ca. 11,500 BP has been found, however it is still questioned whether the rice was indeed being cultivated, or instead being gathered as wild rice.
