Research And Beneift Analysis On O-tillage Technology Of High Altitute Dry&Cold Farming System In Tibet

Since the60’s into the20th century in China, domestic workers have been carrying out a greatdeal of research on0-tillage research. However, most relative researches had been done anddemonstrated in the north of China, arid and semi-arid areas, which aims also to reduce wind erosion,water erosion or mainly to ensure that crop production do not cut in dry conditions. It is the first timeto study planning barley through the introduction of conservation tillage equipment. By comparingsoil surface water use efficiency, weeds survey, changes in soil organic matter, crop productionconstitute and the inputs and outputs under the traditional cultivation and conservation tillagecultivation system, the main findings are as follows:1、Straw mulching in Conservation tillage can reduce soil moisture evaporation and improvewater utilization. Soil moisture of0-tillage farming methods in the0-5cm of tilth soil is batter thantraditional cultivation. In the0-tillage farming methods way more moisture is invalid, so that soilmoisture for seed germination, emergence earlier than traditional farming.2、Compared to traditional farming methods and conservation tillage can increase the incomeof the farmers. Not only the adoption of conservation tillage technology methods can reduceoperating processes but reduce production costs, low labor, low energy consumption and productionhas significant effects, significantly increase the income of peasants. Studies show that the cost ofconservation tillage technology can reduce55.0yuan per mu and save1.3L fuel per mu comparingthe conventional farming methods.3、Because reduce the process of land in conservation tillage, there is no effective way todestruct weeds and the weeds problem is even more prominent. Weeds and crops compete forresources in order to survival batter. Further study on weeds control should be done, so that no-tillagemethods to play a greater production potential.4、The study show barley0-tillage in Tibet has a good prospect.
