If we use the (more conservative) two to three times the remuneration of labor input and to understand, which means that each grain from the farm into the main species - support as well as food and weight - meat - vegetables and farm will be able to accommodate heavy two to three times the labor force. In other words, if the 1980s with the modest scale of grain-oriented 30 acres in the north, south is 20 acres, today's food - vegetables and species - to support and heavy farm north of its modest size is 10 to 15 acres, south 7 to 10 acres.This scale in many places today have been able to do. The current per capita arable land is 2.4 acres, 7.3 acres per worker. If a farm labor to calculate the two (not preclude other members of the migrant workers), which is an average of 14.6 acres, then, today, many areas have been fully able to achieve such a modest scale of full employment of labor, especially in highly specialized labor-intensive cultivation (vegetable growers every professional labor only twenty-three acres of land). The future structure of food consumption based on new and appropriate to promote the further evolution.In addition, from the primary processing of meat - fish and vegetable products to a higher proportion of deep processing of fine, should result in higher capacity and labor income. China's food industry today, the relative proportion of agricultural output - 0.3 to 0.4 to 1 - still far below the developed countries 2-3 to 1 in this regard, China's agriculture is still much room for development.In addition, post-industrial era of science and technology should be able to improve the productivity of land and labor capacity to provide many possibilities. For example, the Ministry of Agriculture since 2003, has been promoting the "straw farming" model may have considerable potential. With the new biotechnology, many rural areas of abandoned crop straw burning, you can use a small amount of biological agents and into high-quality, low cost of livestock feed. According to reports, a pound of straw fermentation agents can be within three days to a week of bio-fermentation one ton finished feed. In addition, the "decomposition agent" said to be without the stalks of silage fermentation and decomposition, not only for sheep and other ruminants, pig and chicken, etc. can also be used for monogastric livestock. As we all know, the traditional farming methods - grazing grass-eating cattle, sheep, feeding the pigs to eat well in captivity, birds - are facing severe resource constraints, either over-grazing grass to speed up desertification, or the consumption of food animals led to food shortages. However, different breeding straw, it is not competing with them but to save food grain feeding, can be considerable increase per unit area of ??land that can support the amount of livestock. It is reported that pig with food, just enough to raise an acre of corn, a pig, and decomposition of straw through the use of an acre of corn, enough to feed five pigs. Thus, the relative corn only, it may be up to three times revenue. And such a straw culture, its development may be quite broad, since all kinds of straw every year 500 million tons of communism, coupled with teasel so it reached 700 million tons.
