项目摘要

Processed liquid cattle manure released from the manure processing plant contains various amounts of mineral and organic components which are useful for plant growth, and which have been considered as a source of fertilizers. The present study was conducted to clarify the possibility of utilization of processed liquid cattle manure (PLCM) to cultivate fruit vegetable crops, such as tomatoes and strawberries, and some leaf vegetables, and also to verify the cultural system to grow them.In order to clarify more clearly the cause of growth reduction at PLCM application treatment, cultural systems, kinds of crops grown, the concentration of liquid fertilizers, and the concentration of fertilizer to be added were studied. The main causes of growth reduction seem to be higher pH and bicarbonate concentration, and some growth inhibitional substances an addition to the unbalance of ionic composition, higher salinity levels. It has been shown that one of the main causes of he reduction might be … More higher pH of the PLCM, but the presence of inhibitional substances were not clarified. The possibility of the utilization of PLCM to grow vegetables should be increased, if inhibitional substances are specified and the methods to remove obstacles are found.When tomatoes were grown in sand and soil cultures, it is possible to apply the PLCM for the cultivation, because plant growth and yield were only lower to some extent in PLCM treatments than in the control, and BER incidence was almost same between PLCM and control. The anaerobic modified PLCM characterized as high concentration of mineral composition also has possibility to be used as the liquid fertilizer, if the composition is adjusted. As the result of cultivation using the anaerobic modified PLCM, fruit SSC became higher and the fruit quality was improved, although the fruit size decreased. The possibility of utilization of PLCM for stonewall culture of strawberry was also investigated with comparison to application of green material composts obtained from food processing companies. As the results, the quite high possibility has been shown as well as the green material composts. Less

从手动加工厂释放的加工液体牛手册中包含各种矿物和有机成分，这些矿物质和有机成分对植物的生长有用，并且被认为是肥料的来源。 The present study was conducted to clarify the possibility of utilization of processed liquid cattle manual (PLCM) to cultivate fruit vegetable crops, such as tomatoes and strawberries, and some leaf vegetables, and also to verify the cultural system to grow them.In order to clarify more clearly the cause of growth reduction at PLCM application treatment, cultural systems, kinds of crops grown, the concentration of liquid fertilizers, and the concentration of fertilizer添加是研究。生长减少的主要原因似乎是pH和碳酸氢盐浓度更高，而某些生长抑制物质是离子成分不平衡（盐度水平较高）的增加。已经表明，HE还原的主要原因之一可能是……PLCM的pH值更高，但抑制性物质的存在尚未澄清。如果指定抑制性物质并发现去除障碍物的方法，则应增加利用PLCM种植蔬菜的可能性。当西红柿在沙子和土壤培养物中生长时，可以将PLCM应用于培养，因为在PLCM处理中，植物的生长和产量仅在某种程度上低于对照中的一定程度，并且PLCM和对照之间的BER入射几乎相同。如果调整了组成，则以高浓度的矿物质成分为特征的厌氧修饰的PLCM也可以用作液体肥料。通过使用厌氧化修饰的PLCM培养的结果，果实SSC变得更高并提高了果实的质量，尽管果实的尺寸降低了。与从食品加工公司获得的绿色材料堆肥的应用相比，还研究了使用PLCM用于草莓板条培养的可能性。结果，已经显示出很高的可能性以及绿色材料堆肥。较少的
