Abstract | |||||||||||||
| 1.イチゴ麗紅と女峰を2つの培養液濃度で, 養液栽培NFTにより栽培した.2.両品種ともNFT栽培で実用的な生育・収量であった.3.NO_3-N濃度に比例関係の強いEC値により培養液濃度を制御した場合やPやKの不足を招くことがあった.4.NO_3-N, Ca, Mgの吸収量の差は2つの濃度区で明瞭でなかった.5.NFTでイチゴ(麗紅, 女峰)栽培を行なう好適培養液組成として(NO_3-N:P:K:Ca:Mg=6:2:4:3:2me/l)の比率が考えられた.. 1. Strawberry plants c. v. "Reiko" and "Nyoho" were grown in Nutrient Film Technique (NFT) with two levels of nutrient concentrations. 2. Plant growth and yield were favourable for both cultivars in the present NFT experiment. 3. Depletions of phosphorus and potassium were occurred when the nutrient solution was controlled by means of electric conductivity, which was closely related to the concentration of nitrate nitrogen. 4. The differences in absorption of nitrate nitrogen, calcium and magnesium were negligible within two nutrient concentrations. 5. The optimum component of nutrient solution for growing strawberry plants c. v. "Reiko" and "Nyoho" in NFT was recommended to be 6 : 2 : 4 : 3 : 2me/l for NO_3-N : P : K : Ca : Mg, respectively. | |||||||||||||
