Introduction Cassava
Cassava is three tubers (cassava, potato, sweet potato) one of the world but also one of the world's annual output of over seven million tons of crops, many tropical and subtropical regions of the main energy source of daily food, and it is important renewable energy substances. Meanwhile, cassava is also an important economic crop of tropical and subtropical regions, it plays an important role in our hot industry. In recent years, with the development of cassava starch, alcohol and processing industry, increased demand for raw cassava, cassava cultivation area
increased year by year in China, the 2011 planting area of about 800 acres, second only to tropical crops sugarcane, rubber. However, China is still a serious shortage of fresh potato material, it needs to import large quantities of dry cassava chips and starch annually, thus cassava cultivation in China has a very broad prospects for development.
Traditional cassava production is labor intensive, requires a lot of labor, especially the part of the harvest. Our country and the vast majority of the world still rely mainly on inefficient livestock operations, is the largest cassava production labor intensity, labor occupy most of a job, accounting for 61% of total cassava production operations, as well as full mechanization of cassava production technology key.
Harvesting cassava products are mainly underground tuber, tuber harvest volume. Different varieties of soil and its roots at the surface irregular distribution and succulent crisp, easy to harvest artificial root cause damage, especially on the hard soil dry land will cause great damage and loss of roots. Many farmers in order to facilitate the hand-pulled, the use of shallow tillage planting shallow cultivation, which greatly affected the plant efficiency. The mechanization of the harvest, not only the loss of root damage, which crushed potato, potato injury and broken skin, although the rate of change varies with soil conditions, but under the same conditions are far below the manual work and high productivity, low operating costs. Currently, the world's cassava-growing countries to increase productivity, reduce operating costs, ease labor shortages, are actively promoting the research and application of cassava harvesting machinery.
