2)  rice straw return
稻草还田
1.

稻草还田(土)的产量效应因氮肥水平、秸秆施加量和作物不同而异。
3)  Straw incorporation
稻草还田
1.
Field studies were conducted to investigate effects of rice straw incorporation and nitrogen application models on process of nitrogen uptake by rice paddy ecosystem and fertilizer-N use efficiency in the double rice cropping system.

2.
To investigate the effects of rice straw incorporation and nitrogen application models on nitrogen supplying capacity of soils,nitrogen using efficiency and rice productivity in the double rice cropping systems,field experiments were conducted on a farmer s field in Taojiang County in April of 2003,using split-plot design with two main treatments,three subplot treatments and eight replications.
结果表明,稻草还田改善了土壤的供氮能力,不论在背景氮较低的砂性土壤上还是在背景氮较高的粘性土壤上,稻草还田配施减量氮肥(N1、N3处理全年施氮量180kg。
4)  incorporation of rice straw
稻草还田
1.
A two-year field experiment was conducted to investigate effects of application of N fertilizer and incorporation of rice straw on nitrogen supplying capacity of the soil and rice yield under a double rice cropping system.
通过田间试验研究了2 a定位试验后不同施N模式和稻草还田对双季稻作系统土壤供N能力和水稻生产的影响。
5)  Rice straw returning
稻草还田
1.
Effects of long-term rice straw returning on the fertility and productivity of purplish paddy soil;
长期稻草还田对紫色水稻土肥力和生产力的影响
6)  straw returned to field
稻草还田
1.
In Yongzhou of Hunan, with fixed position plot trials, ways of straw returned to field and sorts of mulching had been compared for series three years.
在湖南永州进行了连续三年的烟田稻草还田方式和覆盖物种类的定位试验,研究结果如下: 烟田不同稻草还田方式对土壤理化性状和烤烟产质量的影响研究表明,两种稻草还田方式均能改善土壤结构,稻草覆盖比稻草翻压的改土效果更为明显,两种还田方式对土壤营养状况的影响规律比较一致。
2.
The experiment was conducted to study effects of chicken manure and straw returned to field on carbon and nitrogen metabolism, chemical components and economic properties of K326, the major flue-cured tobacco variety in Fujian.
本试验以福建主栽品种K326为材料,研究了鸡粪有机肥和稻草还田互作对烤烟碳氮代谢、化学成分以及经济性状的影响,旨在探讨稻草和鸡粪有机肥不同处理调控烟叶品质的机理并寻求提高烤烟产质的合理组合,结果如下: 稻草还田与非稻草还田根部烟碱都在移栽后75天达到最高,稻草还田茎烟碱在移栽后75天达到最大值,比非稻草还田提前30天,而全株叶烟碱的大量累积都从移栽后60开始并在105天达到最大值。
3.
In yongzhou of hunan,with fixed position plot trials,the effect of straw returned to field,straw mulching,film mulching,no mulching and no returning had been compared for series three years.
结果表明,两种稻草还田方式均能改善土壤结构,稻草覆盖比稻草翻压的改土效果更为明显;稻草覆盖在烤烟生根期的保温作用不如地膜覆盖,烤烟进入旺长期以后,稻草覆盖土壤温湿度变幅较小,能够维持相对适宜的温湿度状况,而地膜覆盖及裸栽处理烤烟整个生育期土壤温湿度变幅较大,不利于烤烟生长。
