Lax to growing hill up soil to ask, but grow in loose and fecund loam optimal.

The ground of prepares ground of 1.1 cuttage nursery choice cuttage nursery before 1 cuttage should choose earthy and relief evenness, loose, source of water enough, illumination the loam of good, small acidity sandiness that does not have damage caused by a windstorm and freeze injury, control of height above sea level is under 700m, traffic compares convenient place. Cent of bedding of soil preparation of bedding of 1.2 soil preparation undertakes 2 times, first time is comprehensive soil preparation, soil preparation deepness amounts to 30cm above, combine bedding the 2nd times, 15cm of soil preparation deepness, etc of cleared block, fireweed is sundry, make land as far as possible fine.

其主要的技术要点如下。1扦插前的预备1.1扦插苗圃地的选择扦插苗圃地要选择地势平坦、土质疏松、水源充足、光照良好、没有风害和冻害的微酸性沙质壤土，海拔高度控制在700m以下，交通比较方便的地方。1.2整地作畦整地作畦分2次进行，第一次全面整地，整地深度达30cm以上，第二次结合作畦，整地深度15cm，并清除石块、杂草及其他杂物，尽量将土整细。

So the Hydrus 2D was selected to simulate the soil water movement in ET covers with different cover thicknesses,the simulations shown that the optimal ET cover in Wuhan area should be 120-140 cm loamy soil layer with shrub.

因此采用Hydrus 2D软件对不同土层厚度腾发覆盖系统的渗沥控制效果进行数值模拟，结果表明，在武汉地区采用120～140 cm厚度壤土层和灌木构成的腾发覆盖系统是确保渗沥控制效果的经济合理方案。

However for P supply, DAP was found superior source and rock phosphate tended to be equally effective source of P in acid laterite soil.

不过对于磷素供应来说，磷酸二铵是最好的来源，磷矿粉在酸性红壤土上同样有效。

Soil culture experiment was employed to explore the effects of phosphorus or lime applications on biomass and mineral compositions in two lespedeza species different in Al sensitivity.

采用红壤土培试验，研究了施用P、Ca对耐Al性不同的两个胡枝子品种的生长和矿质元素含量的影响。

You may have heard the term loam before, but you weren't too sure about what that meant.

您可能已经听说任期壤土之前，但你也不太清楚什么意思。

Soil quality is not high, for the sand and sandy loam.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
