2007年4月12日，时任中国驻日本特命全权大使王毅代表中国国家汉办与早稻田大学总长白井克彦共同签署了合作建设研究型孔子学院的协议，标志着全球第一所研究型孔子学院正式落户早稻田大学。2007年11月12日，双方签署执行协议。

Echinochloa crusgalli is one of main chemical control weeds in paddy fields. It is one of the key factors of rice stability yield to control effectively barnyard grass.

稗草是直播稻田及水稻轻型栽培的主要杂草，控制好稻田稗草是直播田稳产的关键因子之一。

Under different winter cover crop conditions, the ability of absorption of nutrients and growth of late rice were improved, so that the biomass accumulation of late rice of T1, T2, T3, T4 were higher than that of CK.

结果表明：不同冬季覆盖植物均能改善稻田土壤肥力状况，提高稻田土壤有机碳和全氮的含量，促进晚稻对养分的吸收和植株生长发育。

Coleoptera species accounted for the greatest share in phytophagous insects, and spiders were the major natural enemies. The largest proportion of neutral insects was dipteran.

稻田节肢动物中各目、科的种类数量所占比例差异很大，在植食性昆虫中鞘翅目所占比例最大；在天敌中以蜘蛛类最多；在中性昆虫中，以双翅目比例最大；同时在物种、功能集团和营养层3个组织层次水平上分析了稻田节肢动物群落的结构和多样性。

The saturated carbon storage of 100% straw combined with green manure incorporation was 65.77% higher than that of current carbon storage.

研究表明，稻田土壤的饱和固碳量可以通过人为措施进行调控，增加有机物质的投入量和冬季绿肥种植是提高稻田土壤固碳能力的有效途径。

Based on the mutualistic symbiosis relationship of rice and duck, jointed with no-tillage technique, the new no-tillage system of raising duck in paddyfield was formed.

在利用稻鸭互利共生的关系的基础上，将免耕技术引入稻田生态系统，形成稻田免耕养鸭技术新体系。

Those results implied that the field investigation should be started from bund toward middle of field for snail population and weed plants for eggs, and the population of golden apple snail could be managed effectively by adjusting the level of irrigation water.

从埂边向稻田中部调查螺量或从田埂杂草向稻田中部稻株调查卵量，更能代表水稻田福寿螺螺卵量的实际情况；通过调节稻田水位可以控制福寿螺的发生和危害。

To combine raising fish in paddy field and feeding duck in open in paddy field and form a new kind of compounded ecosystem, and make paddy- the biggest primary producer in rice field and fish, duck-the greatest consumers band together organically, and form a benign and high efficiency compounded ecosystem which rice, duck and fish live together.

将稻田养鱼和稻田露宿养鸭有机结合起来形成新的复合生态系统，使稻田中最大初级生产者的水稻与最大消费者的鱼、鸭有机结合起来，形成稻-鸭-鱼共栖的良性高效复合农业生态系统。

However, information on agricultural practice to improve this kindof soils is rather scanty. In the present study, field experiments were conducted tostudy on effects of fertilization practices on the physico-chemical properties and thecrop productivity in gleyed paddy soils from the slate in Taojiang county and theQuaternary Red Clay in Ningxiang county, respectively.

本文通过田间小区试验，研究了几种施肥措施对桃江县板页岩母质发育的潜育性稻田和宁乡县第四纪红土发育的潜育性稻田的土壤的理化性质以及作物生产力的影响，以期为这两类退化稻田的改良修复提供依据。

Rice production and sustainable development for agriculture in China waslimited by poor quality of gleyed paddy soils, such as the accumulation of reductivesubstance, low availability of soil nutrients and declined soil productivity, due to poordrainage. In the past, researches focused more on engineering technology to improvegleyed paddy soils.

潜育性稻田由于其排水不畅，造成稻田土壤通气不良、还原性有毒物质累积、养分有效化过程受阻以及土壤生产力下降等一系列问题，严重影响我国的水稻高产稳产和农业可持续发展，过去的研究仅局限于工程措施改良潜育性稻田，对施肥等农艺措施研究不够。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
