项目摘要

There is a nutrient control method to produce the tomato fruits of high sugar content in soilless cultivation. The nutrient control by the water stress and the salinity stress affects the quality and the yield of tomato fruits but as of now the method of the nutrient management depends on the practical experience of farmer. Therefore, an advanced nutrient control technology is needed to produce the tomato fruits aimed sugar content and quality surely. The nutrient control method based on the constituent information in the growing tomato fruits is considered as a method of achieving such a technology. That is, it can also use it to judge the just harvest timing of fruits at the same time as being able to reflect this information in the nutrient control in real time if the constituent information in the on-plant tomato fruits can be detected by the near-infrared spectroscopy. In this research, when the constituent information in the immature tomato fruits of on-plant was monitored by the near-infrared spectroscopy, expecting the sugar content it ripened into full maturity, and the constructing the system to reflect this in the nutrient control became possible (patent fillings "nutrient controller"). Farther more, in addition to the constituent information in the fruits, to obtain the earlier stress information of plants, the calibration model was developed to measure the water potential of the plant leaf nondestructive on the site that is the index of the water stress of the tomato plants, and the system that was able to measure the water potential of the tomato plant leaf nondestructive in real time on the site were constructed. As a result, the nutrient control based on the water potential information of on-plant leaf became possible. These results are four papers and three patent applications. A prototype device is made for practical use, and it aims at commercialization.

有一种营养控制方法可以在豆浆栽培中生产高糖含量的番茄果实。水胁迫和盐度胁迫的营养控制会影响番茄水果的质量和产量，但截至目前，营养管理的方法取决于农民的实际经验。因此，需要先进的营养控制技术来生产番茄果实的糖含量和质量。基于生长番茄水果中成分信息的营养控制方法被认为是实现这种技术的一种方法。也就是说，它还可以使用它来判断果实的正当收获时间，同时，如果可以检测到植物番茄水果中的组成信息，则能够实时反映营养控制中的信息近红外光谱法。在这项研究中，当近红外光谱法监测未成熟番茄果实中的成分信息时，期望它将其成熟到完全成熟的糖含量，并且构建系统以在营养控制中反映这一点，就可以使用这种糖分。（专利填充物“营养控制器”）。除了水果中的组成信息外，还要进一步获得植物的较早应力信息，开发了校准模型，以测量植物叶的水潜能，在地点上无损害，这是水应力的指数番茄植物以及能够实时在现场实时测量番茄植物叶子无损的系统。结果，基于植物叶的水潜在信息的营养控制变得可能是可能的。这些结果是四篇论文和三项专利申请。制造了一种原型设备供实际使用，其目的是商业化。
