| 5. | By using correct crop management practice , the yield of rice could be increased from present level 采用正确的作物管理措施,可使目前水稻产量水平得到提高。 |
| 6. | For all the soil and crop management treatments , the total runoff decreased with increasing amounts of fertilizer inputs 对土壤和作物管理的所有处理来说,总径流量随肥料投入量的增加而降低。 |
| 7. | At the same site in indonesia , the amount of runoff was affected by the soil and crop management and fertilizer inputs ( table 3 ) 在印尼的同一试验点,径流量也受土壤和作物管理和肥料投入的影响(表3 ) 。 |
| 8. | In most cases , the yield difference is established by soil and crop management and this fact is reflected in the national yield average for different countries ( table 1 ) 大多数情况下,产量差异起因于土壤和作物管理,这表现在各国全国平均产量上(表1 ) 。 |
| 9. | Possibly it is due to the integrated effects of crop management practices such as n distribution at different stages and tillering controlling methods used on different soils 这可能是因为不同土壤上采用的作物管理措施的综合效益,比如不同生育期氮肥分配和分蘖控制方法等的差别。 |
| 10. | For a given rice variety , the crop harvest index , which is calculated by the grain yield divided by total dry matter produced above ground , may vary with crop management practices used 对于给定的水稻品种,作物收获指数(由籽粒产量除以地上部分总干物重求得)可能随作物管理措施不同而变化。 |
