| 中文摘要: |
| 陕北农牧交错带土地生产潜力为1459kg/hm2,现实生产力794.5kg/hm2,人均粮食占有量350.67kg,仅达到我国规定的最低消费水平的标准。要达到中高消费水平,必须增加粮食作物产量,提高土地人口承载力。应该采取的措施是:提高植被覆盖度,控制土地荒漠化;发展设施农业和灌溉农业,提高作物产量;改进施肥方法,培肥地力;因地制宜,开发滩区。 |
| 英文摘要: |
| The land productive potential is 1 459 kg/hm2 and the a ctual productivity is 794.5 kg/hm2 in agriculture and pasturage interlaced zo ne of northern Shaanxi. At present, the grain output per capita is 350.67 kg whi ch is not more than the lowest consumption standard formulated by China. To mee t the middle and high standards of China and the world, crop production should b e improved so as to raise population bearing capacity. Thus the following measur es should be taken into practice: increasing vegetation to control land desertif ication; developing installation agriculture and irrigation agriculture to incre ase crop production; improving means of fertilization to raise soil fertility; e xploiting bottomland in line with local conditions. |
