Therefore, planting scallion in summer fallow period in greenhouse can meliorate obviously soil biological environment and growing fast leaf vegetables and sweet corn can reduce obviously the accumulation of nutrient in the soil and inhibit the formation of alkalization.

从本试验的结果来看，在温室夏季休闲期种植大葱可以明显改善土壤的生物环境，种植速生叶菜和甜玉米可显著降低土壤的养分积累，减缓次生盐渍化的形成。

Through development of multiple cropping to exploit the sunlight resources, thermal resources, water resources and soil resources of farmland in summer fallow period is very helpful for improvement of soil fertility and to prevent fie...

发展多熟种植，开发利用夏闲期农田光热水土资源，有助于改善农田土壤肥力、缓解农田生态系统退化、增加农区畜牧业饲料来源，实现农牧结合，增加农牧民经济收入。

Effect of water saving was studied under no-tillage with straw mulch, conventional tillage with straw incorporatedand conventional tillage on bare ground. The results showed that NTS increased soil water storage by 30.6 mm and 23.9 mm over CTS and CTB during summer fallow.

对免耕覆盖、秸秆还田和常规耕作在休闲期的节水效果研究表明：在夏季休闲期，免耕覆盖比常规耕作多贮水30.62 mm，比秸秆还田多23.91 mm；在冬季储水灌溉期间，可将储水定额从2 100 m3/hm2减少到600和975 m3/hm2。

Results indicated that under the conditionwhen there is lack of water in the soil, deep ploughing will lead to dec-rease yeild before sowing, deep ploughing will aggravate the dispellingof the soil water when the field is fallow in the summer.

旱地闭口过暑具有明显地保墒作用；耕层经常保持5—10厘米的细土或人工地表覆盖，可大大降低蒸发量，保墒效果显著，并对提高地温、增加土壤有效养分、增加小麦分蘖、促进根系发育、降低冻害、增加产量有明显作用。

So while the sonic territory Isolée initially opened up was surely broad and fertile enough to continue yielding a solid harvest for years to come, October shows he's still got the urge to explore and enough navigation sense not to start digging on fallow ground.

因此，我们不得不感叹，只要Isolée开启自己的音乐国土，那定是一片辽阔而又肥沃的音乐家园，并可以在数年的时间都获得稳固的成功与收入。可以说，在此次的新专辑《October》中，他也表达了在不断的尝试中挖掘新音乐形式，新音乐类型的渴望。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
