重壤

同时，还着重分析了重壤带的土娄土在不同肥力水平下其物理性质的变化规律。

In the mean time , we also analysed changing laws of Lou soil ? s physical properties in heavy loam soil region under different fertility level .

在试验期内，粘粉质和粉砂质重壤上鱼腥草干物质积累曲线均表现为S型，而砂粉质重壤上鱼腥草干物质积累，至收获时仍处在直线增长期。

During testing period , the accumulated curves of dry matter of Houttuynia cordata grown on clay silt loam and silt sand loam presented logistic ones , but those grown on sandy silt loam were still in line growth period .

在水稻种植早期阶段产量很低，因为这种荒地盐分太重、壤肥力太低。

In the early period of rice-growing , the yield was very low due to the heavy salt and poor fertility of the wastelands .

结合槐沟水力冲填坝的施工情况，在重粉质壤土地区修筑较高的土坝，采用水力冲填法施工的经济合宜性还有待进一步探讨。

In the weight loam area , the economic feasibility of constructing higher dam by hydraulic fill method needs to be discussed in future .
