Soil Cultivation Test Environmental conditions were adjusted in an artificial meteorological device at a temperature of 23 ° C., an illuminance of 5000 Lux with a fluorescent lamp, a day light / dark cycle of 16 hr light period, and an 8 hr dark period. The prepared corn was transplanted into a No. 3 (9 cm) pot. During the test period, EC was adjusted by adding an appropriate amount of 10% NaCl solution once a day to bring the salt stress to a predetermined value. A treatment liquid containing the compounds shown in Table 2 at a predetermined concentration (with the balance being water) was prepared and subjected to foliar spray treatment. Table 2 shows the conditions of each test section.
  • each test group is prepared as 10 test plants, the average value of the raw plant weight of each individual after 2 weeks from the start of the test is calculated, and the relative value when the untreated group in each EC condition is 100 is calculated.
  • a reference example was created as an appropriate cultivation condition in which no stress occurred, and the plant vitality performance was examined.
  • none of the products of the present invention showed a growth effect under the conditions without the stress of the reference example, whereas the growth effect was extremely high under salt stress conditions with a high EC value. It was confirmed that the plant vitality imparting performance was high. Further, even when the product of the present invention was compared with the comparative product, it was confirmed that the plant vitality imparting performance of the product of the present invention was high under each salt stress condition.

The results obtained are shown in the table. As a result, as shown in the table, the products of the present invention do not show any growth effect under the conditions without the stress of the reference example, whereas the salt stress conditions with a high EC value show a very high growth improvement effect, It was confirmed that the plant vitality imparting performance was high.
