| 中文摘要: |
| 对呼伦贝尔市阿荣旗三道沟镇商品粮生产基地主要粮食作物的光合、光温、气候、气候-土壤资源潜力进行分析,结果表明热量条件是限制该地区粮食增产的主要非可控因素,如能改善热量条件,还有20%～30%的增产潜力;该地区的降水条件对玉米、大豆、马铃薯、水稻四种主要粮食作物的满足程度在80%左右,表明降水量及其季节分布是该镇粮食产量低的制约因素之一,存在的问题是水分利用率较低;土壤养分状况对马铃薯和水稻增产未表现明显的限制作用,而对玉米和大豆增产却是最主要限制因素。 |
| 英文摘要: |
| The productive potential of photosynthesis, light-temperature, climate and climate-soil resources is analyzed for the main crops in Sandaogou, Arong county, Hulanbeier city, Inner Mengolia. The results show that heat energy is the main uncontrollable factor that limits the production of crops in this area, and the yield can be increased by 20%30% if the thermal condition is improved. The sufficiency rate of rainfall to the main crops is 80% or so, showing that the amount and seasonal distribution of rainfall is one of the factors that limit the production. The soil nutrients condition does not remarkably limit the productivity of potato and rice, but it is a main limiting factor to the productivity of corn and soybean. |
