| 3. | The goal is to develop a conservation tillage system applicable to the majority of annual crop farmers in imar
马力。目的是在内蒙古的大多数一年生作物生产区建立保护耕作体系。 |
| 4. | The lanpocun " pig - gas - food " circular economy eco - system was formed based on the circular economy theory and modern tillage system theory , and the research on it was done based on the system dynamic theory
摘要本文在循环经济理论和现代农作制度理论的基础上设计了兰坡村“猪沼粮”循环经济生态系统，并利用系统动力学理论对该系统进行了基模研究。 |
| 5. | In order to improve angriculture conservation tillage system of dry - land area further , the power consumption and throwing characteristic of the new - type sawtooth anti - blocking mechanism developed by dr . liao qingxi were investigated in this paper
本课题为了进一步完善旱地农业保护性耕作系统，对廖庆喜博士提出的新型锯齿防堵装置进行了功耗测试及防堵性能的实验研究。 |
| 6. | It is apparent that the value of controlled - release nitrogen and urease inhibitors is most evident in situations where rapid incorporation is impossible or undesirable due to time constraints or selection of residue and soil conserving tillage systems
在时间紧迫、有残体覆盖和采用保护性的土壤耕作制度下，肥料与土壤不可能迅速混合或混合不理想，此时施用控释氮肥和脲酶抑制剂的效果最明显。 |
| 7. | And the major results and some new viewpoints were presented as follow : 1 ) sediment content of cn tillage system in runoff process is substantially low compared to st under rainfall with high intensity , showing cn bear the efficient capacity of control soil loss . nevertheless , when soil is saturated , the runoff intensity of both tillage systems is near , implicating cn has the limited function of reducing runoff . 2 ) based on the case analysis of observed all rainfall - runoff generation processes , a ) the initiation time hysteresis of surface runoff generation is notable when rainfall fall upon the unsaturated purple soils , which is attributed to the property of rapid water sorption and much non - capillary porosity
经近几年的观测和理论分析，取得了以下结果和创新的认识： 1 )在降雨强度较大的情况下，保护性耕作制? ?聚土免耕的产沙强度明显较常规耕作制? ?顺坡耕作的小，说明聚土免耕耕作制防治土壤流失是有效的；但当土壤达到饱和后，聚土免耕的径流强度与常规耕作的差异较小，产沙强度也增大，因此，聚土免耕防治水土流失的能力是有限的。 |
| 8. | By taking part in the training courses on conservation agriculture and doing fieldwork in shanxi province and other places , lan jie has realized that conservation agriculture is an integrated tillage system . the residue management should be strictly combined with farming techniques and crop rotation
通过参加项目举办的保护性农业培训和到山西等地的实地考察，蓝姐认识到保护性农业是一个综合的耕作体系，必须将农艺措施与秸秆的管理及农作物轮作等因素紧密结合起来。 |
