项目摘要

In this project, the basic and practical studies were conducted for the application of the deep sea water to agricultural processes as a part of the multipurpose and multistage use. The results are summarized in the followings;1.The energy evaluation of the cooling system for the soilless culture and the storage of agricultural products were done. It was cleared that when the deep sea water was used, they became 84%-86% energy saving with the petroleum conversion compared with using a refrigerator.2.The moisture transpiring characteristic of some citrus fruits stored was measured by the method of observing absolute humidity in the storing atmosphere including uptake water temperature 11-12℃ of deep sea water. It was found that the exponential model was applicable to the temperature dependence of the moisture transpirating characteristics of citrus fruit.3.Three-truss cultivation of tomato plant was done using NFT(Nutrient Film Technique)system and examined the influence which the conditions (time, period, concentration) for deep sea water treatment exerted on the fruit quality of each truss and the yield.4.The use of "on-site" NIR measuring system developed, makes it possible to control and modify the nutrient solution based on the internal properties of immature fruits to produce tomatoes at the desired soluble solid content level.5.Based on the buffer action of deep sea water, the structure of water by TSDC method was measured, and in order to control the structure of the nutrient added deep sea water, seedling test was performed in soilless culture system. As the results, the nutrient with the addition of deep sea water was effectively applicable to the soilless culture.

本项目针对深海水在农业过程中的多用途、多阶段利用进行了基础和实践研究，结果总结如下： 1. 冷却系统的能量评估。进行了无土栽培和农产品储存，结果表明，使用深层海水时，与使用冰箱相比，通过石油转化可节能84%-86%。2、水分蒸发特性。一些柑橘类水果通过观测贮藏气氛中的绝对湿度（包括深海水的吸水温度11-12℃）来测量贮藏的柑橘类水果的水分蒸腾特性的温度依赖性。3。 .采用NFT（营养膜技术）系统对番茄植株进行三桁架栽培，考察深海水处理条件（时间、周期、浓度）对各桁架果实品质的影响4.使用开发的“现场”近红外测量系统，可以根据未成熟果实的内部特性对番茄营养液进行控制和修改，使其达到所需的可溶性固形物含量水平。5．为了对深海水的缓冲作用进行测定，采用TSDC法测定了水的结构，并为了控制添加了深海水的养分的结构，在无土培养体系中进行了育苗试验，结果，养分具有良好的效果。添加深海水有效地适用于无土栽培。
