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.

在本项目中，作为多用途和多阶段利用的一部分，对深海水在农业加工中的应用进行了基础和实践研究。主要研究结果如下：1.对无土栽培和农产品储藏的降温系统进行了能量评价。结果表明，使用深海水比使用冰箱节能84%-86%。2.采用绝对湿度法测定了部分柑橘果实贮藏期间的水分蒸腾特性，包括深海水吸水温度11~12℃。利用NFT(营养膜技术)系统对番茄进行了3次网架栽培，考察了深海水处理条件(时间、周期、浓度)对各网架果实品质和产量的影响。4.研制的“现场”近红外测量系统，可以根据未成熟果实的内在特性对营养液进行控制和修改，以生产出所需的可溶性固形物含量水平的番茄。5.基于深海水的缓冲作用，用TSDC法测定了海水的结构，并在无土栽培系统中进行了育苗试验，以控制添加营养物质的深海海水的结构。结果表明，添加深海水的营养液可有效地应用于无土栽培。
