近年来,NFT(营养液膜栽培)被日本国开发和引进,可以预料,岩棉栽培的开发,对水耕栽培的实用化和今后果菜栽培面积的增加将极为有利。水耕栽培与土耕栽培比较,养分管理容易,营养不足等营养障碍不会发生。但是,在番茄栽培中,到生育中后期,从中部叶到上部叶一般较多地发生叶子黄白或黄褐色症状,影响了番茄的产量和质量。一、黄叶多发的水耕番茄栽培床的实际情况与
In recent years, NFT (nutrient liquid film cultivation) was developed and introduced in Japan. It is expected that the development of rock wool cultivation will be extremely beneficial to the practical use of hydroponic cultivation and the increase in the area of fruit and vegetable cultivation in the future. Hydroponic cultivation and cultivation of soil compared to easy nutrient management, nutritional deficiencies and other nutritional disorders will not happen. However, in tomato cultivation, yellowish-white or yellowish-brown leaves usually occur from the middle leaf to the upper leaf during the later growing period, which affects the yield and quality of the tomato. First, the yellow leaves of multiple hydroponic tomato beds and the actual situation
