It's a staple food for the majority of sub-Saharan Africa, and is a great source of carbohyrates, protein, iron, vitamin B and minerals. Plus it is being used more and more for ethanol. Cassava's importance in Africa and South America can not be overstated. As a drought-resistant crop that does well in poor soils, cassava is a starch-heavy lifesaver for low-income areas. Cassava eaters know that the roots and leaves must be cooked in order to lose that toxic level of cyanogenis glucosides. Sweet potatoes are another crop native to South America that is now majorly produced by China. They are only distantly related to regular potatoes, and in the U.S. they are often confused with yams. Sweet potatoes are a great source of protein, vitamins A and C, iron, and calcium. They grow very harmoniously with the earth- few natural enemies make pesticides unnecessary. III.

V. Comprehensive reading and answers the below questions Poplar is an important tree species for both wood production and ecological protection in China. Poplar can be seen everywhere in China, and it has the largest planted area in the north China, central China and in the lower and middle reaches of the Yangtze River. The poplar plantation area has grown to six million hectares in China and it exceeds the total area of poplar plantation in the rest of the world. Poplar alone will produce 20 million cubic metres of wood. In China, poplar plantation is giving more and more economic, ecological and social benefits. A new upsurge of poplar cultivation has been seen in the lower and middle reaches of Yangtze River in the late 70s and early 80s. The new variety P. aganthe, can be grown in the arid northern shelterbelts. Since 1990, fifteen poplar varieties have been cultured for industrial uses....The oriental cultivation technique has been taken seriously for plywood, pulp, fibre board and firewood production according to the demand of industrial processing and ultilization. For this reason, variety selection spacing control and pruning have been studied for industrial plantation. In China, there are some fifty-four kinds of pests and diseases of which thirty species cause severe economic damage. The areas attacked by Anoplophora glabripennis and Apocheima cinerarius reached 0.67 million hectares. The control index, cultivation measures, breeding of resistance to pests, biological control, chemical control and comprehensive control techniques of pests have been studied and great success has been achieved 1.
