Water wasted seriously in agricultural irrigation in our country . the water resources used in agriculture occupies about 70 . 2 % , and the paddy field used about 80 % water resources in it 农业用水占我国水资源消耗量的70 . 2 ，而水田用水又占了农业用水的80左右。
The areas of the main land - use type such as arable land ( paddy field and dry land ) , orchard , built - up land , unused land , have changed in different extent 从变化分析的结果可知，耕地（水田和旱地） 、果园、城乡建设用地、未利用土地等主要用地类型的面积均有不同程度地变化。
The results showed that the wet area increased and the shape of patch was regular , which helped to mechanical work and field management , but the landscape multiplicity was reduced 结果表明：整理后水田面积增大，斑块形状规则，有利于机械化作业和田间管理，但同时景观多样性略有降低。
Based on historical records from huizhou , this paper calculates the annual ratio of investment and profit on the absolute sales of paddy land was 6 . 67 % prior to the qianlong period 摘要清代徽州购买水田（绝卖）的年度投资回报率仅为6 . 67 % ，而所举五个一般商业投资实例的年度投资回报率则在9 - 18 %之间。
The sampling area lies in jiangjin city , where is undulating topography , purple soil and paddy field soil account for most of its soil types , the status of land use are paddy and dry land 本次试验的采样区位于江津市，为低山丘陵地貌，土壤类型主要为紫色土和水稻土，土地利用现状主要为水田和旱地。
From the land reform in 1956 to the contracted responsibility system with remuneration linked to output ( crsrlo ) in about 1981 , alum in southern yunnan experienced two major changes 土改后到包产到户前，滇南的农地利用模式主要发生了两个大的变化：在旱地十林地型地区，开始出现水田并日益占有重要地位
The region was crisscrossed by myriad rivers , canals , and irrigation streams that fed lush market gardens and paddies in which the young rice shoots grew , or flowed into lakes and ponds where fish and ducks were raised 这里河流水道交错、灌溉沟渠纵横，滋养了稻穗累累的水田，也流入一望无际的湖泊和养鸭、鱼的池塘。
Accordingly , menses avoids cold stimulation as far as possible , prevent to issue half body catch cold catch cold especially , following paddy fields , get wet in the rain , cold bath foot , bathe cold water , sit to wait coolly 因此，月经期尽量避免严寒刺激，非凡是防止下半身受凉，如下水田、淋雨、冷水洗脚、洗冷水澡、坐凉地等。
The degradation rate of map was 79 . 95 % in 5 days when the water content in soils was 150 % ( paddy soil ) in laboratory test . the test also showed that degradation rate in paddy soil was higher than that in upland soil 在模拟水田和旱田试验中，加菌5天后水田土壤中甲胺磷的降解率为79 . 95 ，同时发现菌株在水田中的降解效果要好于旱田中的降解效果，含水量高有利于土壤中农药的微生物降解。
