[Test example] 1. Test purpose: To test the effect of magnets installed in the liquid supply pipe for hydroponically grown tomatoes on growth promotion and quality improvement on tomatoes. 2. Materials and Methods (1) Test location: Mikado Breeding Farm Otaki Research Farm (2) Hydroponic facilities used: NFT hydroponic facilities (3) Test plots Control plots: In accordance with water supply pipe practice (30 plots as 1 plot) Magnet mounting area: Attached to the liquid supply section of the bed of the liquid supply pipe (near the bed) (30 strains were set as 1 area). (4) Outline of cultivation Seeding the tomato variety "Misora" and sowing seeds in 1999 On September 1, the planting was carried out on October 4. The culture solution was managed according to the custom. Other controls were in accordance with practice. (5) Survey items: a. Growth and ecology research: First inflorescence stage, second inflorescence stage, etc. b. Cultivation solution survey: Changes in EC and pH values, etc. c. Environmental survey: temperature and liquid temperature Results and discussion (1) Tomato growth (Table 1). The growth of the tomatoes in the magnet-attached section was higher than that in the control section, with higher plant height, thicker leaves, thicker stems, darker leaf color, and more vigorous growth. In the tomatoes in the control group, yellowing due to calcium deficiency in the leaves around the fifth inflorescence was observed, and the stem was sharply thinned. . The tomatoes in the magnet-attached section grew vigorously, and the leaf weight, stem weight, average fruit weight per plant and root weight were large. In particular, the fact that the root weight is large indicates that the rhizosphere is distributed throughout the channel and that the activity of the root group is good, indicating that the absorption efficiency of nutrient water is high. (2) Flower setting by flower cluster, fruit setting status and occurrence of butt rot (Table 2) The total number of flowers set was large in the control group, but the total fruit set was large in the magnet-attached section. Looking at the number of fruit set by inflorescence, the difference between the first and third inflorescences was small in both sections, but the number of fruit attachments was large in the fourth and fifth inflorescences in the magnet-attached section. The number of butt rots was particularly remarkable in the control group, and was conspicuous in the second and third inflorescences, but was clearly reduced in the magnet-attached group. (3) Occurrence situation and prevention effect of tomato calcium deficiency (Table 3) Calcium deficiency is observed in young fruits around the early stage of hypertrophy and young leaves around the growing point, and the occurrence is particularly high during the high temperature period, which is a problem. This is presumed to be due to a decrease in root group activity in the high temperature period. From the results obtained in this test, occurrence was observed even in the low temperature period, and it was considered that the attachment of a magnet was effective in preventing calcium deficiency. This is presumably because ionization is promoted by the magnetic force of the magnet and solidification due to solidification of calcium in the solution is prevented, thereby increasing the calcium absorption rate.
