人工配制的营养液养分足、无污染,可以提高花的数量和质量,减少病虫害的发生。因此无土栽培特别适用于温室周年生产切花和居室盆栽观赏。一、无土栽培的几种方法 1.营养液栽培法:在一个平底的长方形水槽中,安放一块可以上下移动的栽培板,按栽培所需的株行距打孔,将花苗固定在孔中,槽内加入营养液。随着根系的不断生长,栽植板不断上移,使根系的新根部分始终可浸入营养液吸收营养,而上部又能保持良好的通气状态。槽内营养液通过水泵使其缓慢循环流动,增加水中的溶氧量。此
Manually formulated nutrient solution enough nutrients, pollution-free, you can increase the quantity and quality of flowers and reduce the occurrence of pests and diseases. Therefore, soilless culture is particularly suitable for greenhouse annual production of cut flowers and bedroom potted ornamental. First, several methods of soilless culture 1. Nutrient hydroponics method: In a flat rectangular tank, placed a plate can move up and down, according to the line spacing required for planting drilling, the flower seedlings fixed in the hole, Trough adding nutrient solution. With the continuous growth of the root system, planting plates continue to move up, so that the root part of the root can always be immersed in nutrients to absorb nutrients, while the upper part of the well maintained good aeration. Nutrient solution tank through the tank to slowly circulating flow, increasing the amount of dissolved oxygen in water. this
