| 1. | Water - saving effects of integrated drought - preventing techniques for winter wheat 小麦干旱综合应变防御技术的保墒节水效应 |
| 2. | Reduce soil moisture 降低土地壤保墒 |
| 3. | The software make the design of the ditcher more convenient , more efficient , higher quality 该软件使得这种新型蓄水保墒机具的设计变得简便、高效。 |
| 4. | This tillage practice was done by farmers to control weeds and conserve moisture during the fallow period before the wheat crop 农民用这种耕作措施除草并在种麦前的休闲期保墒。 |
| 5. | Effects of plastic film mulching on temperature increase and preservation of soil moisture and its responses to growth character of rice with dry - land cultivation 水稻旱作覆膜的增温保墒效果及其对生育性状影响研究 |
| 6. | The paper tutored by professor yang mainly develop the software of the design of a new - style sluice and keeping soil moisture ditcher in visual basic 本研究设计主要内容为利用visualbasic语言编制了一套新型蓄水保墒机具设计软件。 |
| 7. | 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。 |
| 8. | The primary function of the software are confirming the fundamental dimensions of the ditcher , optimizing the volume of reducer , carrying through dynamic , real - time simulation to working part 该软件的主要功能为:确定新型蓄水保墒机具机构基本尺寸;对减速箱的体积进行优化;对工作部件的运动进行实时的、动态的模拟。 |
| 9. | At present over 10 million mu of farm land are covered by the national conservation tillage projects . the conservation projects have greatly improved the water use efficiency , reduced production cost , increased crop yield , increased farmers income 保护性耕作项目的实施,起到了蓄水保墒节本增效抑制农田扬尘增加土壤有机质的作用,并产生了明显的经济生态效益。 |
| 10. | That is , soil reservoir high effective rainwater use model ( srherum ) , field film cover no - tillage evaporation prevent and soil moisture reserve model . both the two models are the models that will play an important role in practice in the future 主要包括梯田土壤水库高效用水模式和农田覆盖少免耕抑蒸保墒高效用水模式两种未来在实践上起重要作用的实践模式。 |
