The main conclusions are as follows : 1 . Compared with bare land for planting of winter wheat seedling and heading stages , Straw mulch reduced 0 ~ 25cm soil temperature .

主要研究结论如下：1.秸秆覆盖处理均较裸地种植降低了冬小麦苗期及抽穗期0～25cm的土壤温度。
2

The herniated organs include the greater omentum , colon , stomach , spleen , small intestine and liver , the width of diaphragm rupture is3 & 25cm .

疝入脏器为胃、大网膜、结肠、脾、小肠及肝脏，膈肌裂口宽度为3&25cm。

It measured 50cm ( 20in ) deep , 25cm ( 10in ) high , 45cm ( 18in ) wide and sits 89cm ( 35in ) above the floor .

据测量，大洞有50厘米深，25厘米高，45厘米宽，距离地面89厘米高。

The results showed that : 1 . In this study , there were no significantly difference of soil catalase , sucrase and urase activity in plowed layers ( 0 ~ 25cm ) under different planting systems , however , these three soil enzymes activities varied with tobacco growth stages .

研究结果如下：1、4种种植模式下耕层土壤（0～25cm）过氧化氢酶、蔗糖酶和脲酶活性均无显著差异，但随时间的变化各异。
