- W2350617811 abstract "In this paper,the annual production of straw in China hilly red soil region from 1993 to 2003 was calculated,according to the economic indices of crop straw and crop yield.The averaged annual straw production was 33.5×10~(10) kg·yr~(-1),accounted for 52.1% of total crop straw production in China.In this region,rice straw accounted for 53.5% of total crop straw,which was 21.4% higher than the average countrywide value.The percentages of other kinds of crop straw in this region were also different with those of the whole country.The changes of rice and other grain crops straw production among years were basically the same to that of all the crop straw in this region,i.e.,an increasing trend was found from 1993 to 1997,but declined then.The changes of economic crops straw production varied with different kinds of crops.The utilization ratios of straw incorporation and industrial use in this region were 32.0% and 6.6%,respectively,which were higher than the average countrywide value,while those for fuel and forage were 22.0% and 14.1%,respectively,which were lower than the average countrywide value.The average percentage of wasted straw was 25.3%,and increased from 20.6% to 29.6% between 1993 and 2003,suggesting that a big amount of crop straw in this region was thrown away or burned,which was obviously a waste of restricted agricultural organic resource.Countermeasures were put forward in this paper to adjust the crop straw utilization framework status,and to enhance the utilization efficiency of crop straw." @default.
