Nutrient solution culture system and using the method of nutrient solution cultivation, and nutrient solution culture with basin

Abstract

The present invention provides nutrient solution culture system and using the method of nutrient solution cultivation, and nutrient solution culture with basin, the system can steadily improve fruit or fruit sugar, and by the root in the optimum range of temperature control, increase the amount of the annual harvest. Flows the system has: aqueduct of nutrient solution cultivation bed (1), set within the cultivation bed and grow to be several of the cultivation of the plant seedling cultivation basin (2), and to the cultivation bed supplies nutrient cycle of nutrient supply system, cultivation formation at the bottom of the bowl (2) the opening of the nutrient solution (3) by circulation, but not through plant roots of sheet parts (4) plug, nutrient solution circulation supply system has: the cycle of nutrient solution tank (7), can often submerged cultivation basin within the flow to the cultivation bed bottom tank pump (9) of nutrient supply cycle, the circulation tank nutrient solution in a predetermined temperature range temperature adjusting mechanism (19, 20), and make the circulation tank nutrient solution concentration change the concentration of the adjusting mechanism (12a, 12b, 17, 18).

Description

technical field [0001] The present invention relates to a hydroponics system for cultivating various fruits and vegetables or fruits which are advantageous for increasing the sugar content, a hydroponics method using the same, and a cultivation pot suitable for hydroponics. Background technique [0002] In recent years, in fruits such as pears and apples, or fruits and vegetables such as melons, tomatoes, and strawberries, the sugar content tends to be higher and more popular among consumers. When cultivating such fruits and vegetables or fruits, a method of imposing water stress by restricting water supply to plants at a predetermined stage during cultivation is widely known as one of methods for increasing the sugar content. [0003] For example, in the following Patent Document 1, a tomato cultivation device is proposed, which has a container-shaped cultivation bowl, and is attached to the inner side thereof, and has a liquid supply sheet having a property of diffusing wa...

Problems solved by technology

[0009] However, in the above-mentioned method of cultivating accompanied by application of water stress, since the liquid phase in the rhizosphere is reduced and the gaseous phase is increased when the amount of water supply is limited, and since the cultivation pot is placed in the air, there is a problem that the root zone The temperature is directly affected by the outside air (the temperature inside the facility in the case of facility cultivation), and especially in summer and other seasons when the outside temperature is high, the temperature of the roots becomes too high, and conversely, in winter and other seasons when the outside temperature is low, the roots The temperature becomes too low for cultivation in any season, and as a result, it is difficult to increase the harvest throughout the year
