| 1 | APSIM模型在黄土丘陵沟壑区不同耕作措施中的适用性显示文摘为了揭示黄土丘陵区不同耕作措施对作物生长发育和土壤水分的影响及相互作用规律,根据2002~2005年两个轮作序列(小麦→豌豆(W→P)和豌豆→小麦(P→W))的3种耕作措施(传统耕作(T)、免耕(NT)和免耕覆盖(NTS))的定位试验,对APSIM模型的适用性进行了研究。通过定位试验得到了一套APSIM模型的参数值,并对其进行了率定。运用均方根误差法对APSIM模型进行检验,结果表明:小麦和豌豆产量与生物量的模拟值与实测值具有显著的正相关(R>0.9),误差范围在±15%之内;土壤贮水量的模拟值与实测值也具有显著的正相关(R>0.7),误差范围在±20%以内。表明APSIM模型可以用来模拟不同耕作方式和不同轮作序列的小麦和豌豆产量、生物量及土壤水分的动态变化,模型可以用于指导作物生产及耕作措施的优化管理。 | 李广 黄高宝 William Bellotti 陈文 | 2009 | 生态学报2009,29,5: | 62 |

| 4 | Benefits of Conservation Agriculture on Soil and Water Conservation and Its Progress in China显示文摘Conservation agriculture has been practised for three decades and has been spread widely. There are many nomenclatures surrounding conservation agriculture and differ to each other lightly. Conservation agriculture (CA) is a system approach to soil and water conservation, high crop productivity and profitability, in one word, it is a system approach to sustainable agriculture. Yet, because conservation agriculture is a knowledge-intensive and a complex system to learn and implement, and also because of traditions of intensive cultivation, adoption rates have been low, since to date, only about seven percent of the world's arable and permanent cropland area is farmed under conservation agriculture. The practice and wider extention of conservation agriculture thus requires a deeper understanding of its ecological underpinnings in order to manage its various elements for sustainable intensification, where the aim is to conserve soil and water and improve sustainability over the long term. This paper described terms related to conservation agriculture, presented the effects of conservation agriculture on soil and water conservation, crop productivity, progress and adoption of CA worldwide, emphasized obstacles and possible ways to increase CA adoption to accelerate sustainable development of China agriculture. | LI Ling-ling HUANG Gao-bao ZHANG Ren-zhi Bill Bellotti Guangdi Li Kwong Yin Chan | 2011 | Agricultural Sciences in China2011,10,6: | 15 |
| 5 | 西部黄土高原苜蓿终止时间对苜蓿-小麦轮作系统生产力及土壤水分的影响(英文)显示文摘旱作春小麦(Triticum aestivum L.)是西部黄土高原最重要的禾谷类作物,该区苜蓿(Medicago sativa L.)分布也非常广泛。持续的作物连作和多年苜蓿种植系统都存在很多问题。雨养农业系统发展的关键是最佳水分利用策略的应用。发展合理的苜蓿-小麦轮作系统对该区农业的发展有十分重要的意义。由于苜蓿终止时间严重影响土壤水分,所以在适宜的时间终止苜蓿就显得十分重要。然而,关于苜蓿-小麦轮作中老苜蓿在一年中适宜终止时间的研究鲜见报道。本研究利用黄土高原西部典型的半干旱雨养农业区30年老苜蓿布设田间试验,旨在探索老苜蓿地土壤水分状况、苜蓿终止时间和少量氮肥施用对系统生产力及土壤水分的影响。结果表明,长期种植苜蓿后0~3m土壤水分很少,即便遇到丰水年(2003年),3年的时间都不足以恢复土壤水分。30年苜蓿在一年中春季还是秋季终止对土壤水分状况无显著影响。种植苜蓿30年后杂草竞争力增强,苜蓿干物质和产量水平都相当低,且对1kg hm-2的氮肥使用无明显响应。由于土壤水分含量太低,后茬春小麦对1kg hm-2的氮肥使用和苜蓿终止时间也无明显响应。因此,苜蓿持续种植时间太长会耗竭土壤水分,使后茬春小麦对苜蓿在一年中的终止时间及少量的氮肥使用无响应,需要3年以上时间才有可能恢复土壤含水量。 | 李玲玲 黄高宝 张仁陟 蔡立群 罗珠珠 晋小军 张恩和 BELLOTTI Bill UNKOVICH Murray | 2011 | 作物学报2011,37,4: | 11 |
