SOLUTION CULTIVATION METHOD FOR LOW POTASSIUM VEGETABLE LOW POTASSIUM VEGETABLE AND CULTIVATION DEVICE

摘要

In the nutrient solution cultivation method of low potassium vegetables, the entire cultivation period from sowing to harvesting is divided into a first cultivation period and a second cultivation period depending on the vegetables to be grown. In the first cultivation period, vegetables are grown in a first culture solution containing a first nutrient cultivation fertilizer containing potassium. In the second growing period, the vegetables are grown in a second culture containing a second nutrient growing fertilizer substantially free of potassium. During the second cultivation period, wind speed controlled wind is given to the growth point of the vegetables.
