六、干旱地区和其它地区低产土壤的改良利用(一)关于加强干旱地区土壤改良利用的建议我国旱地面积约占全国总耕地面积的四分之三,其中没有灌溉条件的旱地占52%.特别是内蒙古包头以东的长城沿线和黄土高原地区,旱地面积占总耕面积的90%以上,这个地区生产、生活水平较低.全面提高这一地区旱地农业生产对改变大西北穷困落后面貌,减少国家供粮压力、及顺利实现中央开发大西北的战略设想,有着十分重要的意义.发展旱区农业虽有种种不利因素,但只要因地制宜、趋利避害、大力种草种树、蓄水保墒、培肥地力、积极推广旱作农业技术,坚持农林牧全面发展,完全可能使整个旱区面貌根本改观.在长期与干旱斗争中,广大群众创造和累积了
VI. IMPROVED UTILIZATION OF LOW-YIELD SOIL IN ARID ZONE AND OTHER REGIONS (I) Proposals for Improving Soil Improvement and Utilization in Arid Areas China’s dry land area accounts for about three-fourths of the country’s total arable land area, with dry land accounting for 52% of the total irrigated area. Is the area along the Great Wall and the Loess Plateau to the east of Baotou in Inner Mongolia where the dry land area accounts for over 90% of the total cultivated area and the production and living standards in this area are relatively low. Comprehensive improvement of dry land agricultural production in this area will greatly reduce the poverty and backwardness in the Northwest, National pressure on supply of grain and strategic vision of the successful development of the Greater Northwest Development by the central government are of great significance.During the development of arid area agriculture, despite all the unfavorable factors, as long as it is suited to local conditions, , Fertilize the land fertility, actively promote the dry farming technology, adhere to the all-round development of agriculture, forestry, animal husbandry and animal husbandry, it is entirely possible to make a fundamental change in the outlook of the entire arid region. In the long-term struggle against drought, the masses created and accumulated
