【摘要】 储液储气式无土栽培装置分成基质、空间和营养液三部分,外型如桶状,内装配网芯一个。该装置较好地调节了装置内固体、气体、液体三相的平衡,解决了无土栽培中根际供液和供氧的矛盾,装置底部的营养液层在一定时间内能持续供给植株充足的营养和水分,使植株能健壮生长。在上海孙桥、新疆、银川示范生产表明,装置具有易于移动、便于提早定植、节省基质和营养液特点。更多还原

【Abstract】 A new soilless culture system for protected vegetable production in China has developed and patented. The shape of the device is like a flower pot with a closely filling hat-like core in its center to separate the pot into 3 parts for substrate, air and nutrient solution. Roots of vegetables could grow -both in the media and into the cavity of the pot to absorb sufficient oxygen and nutrients. This structure successfully balanced the supply and demand of oxygen, water and nutrients.The culture system could be effectively used in China because the features of the system are easily movable, advancing transplant and saving substrates and nutrient solution. Since the special structure had no leaching of nutrient solution, the system significantly decreased the humidity of the ground and greenhouse, thus the incidence of disease was also decreased.更多还原
