| 4. | The comparative study on the two methods for determining the decomposing and retention rate of the organic material in fluvo - agvic soil in henan province was carried out
摘要在河南省潮土上进行有机物料的腐解残留率两种测定方法的比较研究。 |
| 5. | The most economic way is to mechanically " bury " all the harvested straw under the ploughed layer straight away after the harvest , letting it be decomposed there
最为经济的还田方式是在土壤耕作之际将稻草全部翻压在土壤的犁底层，让其在此腐解。 |
| 6. | The main conclusions were as follows : ( 1 ) the residues decayed quickly at 0 - 3 months , slowly at 3 - 6 months , and kept constant at 6 - 13 months basically
主要结论如下： ( 1 )荒漠绿洲生态条件下，残体的腐解以0 - 3个月最快， 3 - 6个月较缓， 6 - 13个月则基本不变。 |
| 7. | The decaying rate of corn straw adding n was higher than that of soybean straw , and the decaying rate in oasis ecosystem was higher than in desert ecosystem
加氮玉米秸的腐解速率大于大豆秸的腐解速率，绿洲生态条件下的腐解速率大于荒漠生态条件下的腐解速率。 |
