• This made her no - tillage fields no different from the traditional ones . this resulted in undermining the role of crop residues in keeping moisture and raising soil fertility
  免耕地很快便与传统耕作地毫无差异，极大地降低了留秸秆根茬保水保墒提高土壤肥力的作用。
• This technical support and training related to the utilization of crop residues is addressed in the " technology transfer " sub - component and the training plans for cow - calf farmers and feedlots
  这些同农作物桔梗的利用相关的技术支持和培训在“技术转让”的次领域和母牛犊牛管理农民和饲养场的培训计划中得到解决。
• Not only could n ' t the quantity of soil organic matter and organic n be lifted up , but also did it lead , to soil erosion and output declining under nc - ti ! ! age system without crop residue adding
  实行免耕制，关键是有机残体的返还。研究表明，一旦免耕与覆盖分离，则免耕即不能提高有机质和有机氮水平，导致土壤退化和减产。
• The environmental management considerations of the project include a pasture management , b reduction of air pollution by feeding , rather than burning , crop residues , c manure management plans for feedlots and d effluent management for processing plants
  通过将农作物桔梗作为饲料而不是烧掉减少大气污染， c饲养场的粪便管理计划，
• When there was not enough fodder however , local herds would flock into her no - tillage fields where crop residues were being retained over winter . the residue and stubble in the fields was devoured by them in no time

• The no - tillage and culture focus more on creating better conditions for microbe decomposing the crop residue compared with no - tillage . there are four principle in it : 1 ) successive capillary water circulation ; 2 ) successive no - tillage ; 3 ) successive multiple crop rotation ; and 4 ) successive " ridge and furrow culture " . by these devices taken , the soil accumulate more organic matter in shorter period compared with general no - tillage
  将秸秆混入土壤中分解，垄、沟搭配，保持土壤的浸润状态和连续植被，不仅解决了覆盖免耕制中有机质分解、转化慢的问题，而且使输入土壤的有机质分解、转化更加迅速，所以在促进土壤有机质循环方面自然免耕制表现出明显的优越性，土壤有机质遂表现为快速的增长。
• This approach seeks to use various sources of plant nutrients , mineral fertilizers , organic manures , crop residues and biological nitrogen fixation for each farm ' s cropping system and offers the farmers the best opportunity for sustainability while protecting the environment and conserving the resources
  这一方法，为每个农场的种植制度寻求利用各种植物养分资源，诸如矿质肥料、有机肥料、作物残体和生物固氮，并且在保护环境和资源的同时，给农民提供更好的持续发展生产的机会。
• Conservation agriculture helps to retain crop residue on the soil surface to minimize water and wind induced soil erosions . consequently , sand storms are reduced . it also leads to increases in soil organic matter by sequestrating atmospheric co2 to reduce greenhouse gas effects
  20世纪80年代，我国科技人员开始对保护性耕作技术进行试验研究，通过研究表明，在中国实施保护性耕作可以起到蓄水保墒节本增效抑制农田扬尘增加土壤有机质的作用，具有明显的经济生态效益。
• Academician hou guangjiong , who summarized the experiences from peasants in sichuan province , promoted the no - tillage and ridge culture in 1982 that has two sides of meaning of its name : one is simulating the physical and ecological characteristics of originally moist soil ; the other means rhat the basic characteristic of perfect soil fertility is no - tillage . the key of no - tillage is the supply the past crop residue to soil
  1982年侯光炯院士根据四川农民和农村科技工作者的实践经验，在总结覆盖免耕和残茬免耕的基础上提出了自然免耕制，其名称有两方面的涵义，一是模拟自然土高肥力的生理生态特征；二是说明高肥力的基本特征是免耕。
• By the crop residue input , priming effects of soil irjcrobe will take place , and decomposition and bio - fixation give rise to soil organic matter arid m in the up layer of soil . on the other hand , tillage accelerate ; ; the organic matter mineralization and leads to the quantity of organic matter decreasing in . . or 10cm . layer which is about 1 / 2 of soil organic matter under no - tillage
  覆盖免耕使土壤上层的有机质和氮素稳定增加，这主要来自被激发的微生物繁殖时对碳和氮的生物固定，而传统耕作则由于耕翻加速了有机物的矿化， 0 - 10cm土层微生物碳含量均一，其数值几乎为免耕系统的一半。
