Tray soilless culture evolved by the nutrient flow technology in which there was only a layer of nutrient liquid and the oxygen was very enough was designed to improve the effect of wastewater purified by the terraneous It was showed that when the height of the tray was 1cm, and six layers of clothes were laid on the tank to filtrate and hold wetness the wastewater, furthermore, the gradient of the tank was between 2 and 8, the tray soilless culture was the most feasible.

为了提高陆生植物净化废水效果，根据仅有一层营养液流过栽培容器的底部而使供氧条件大大改善的营养液膜技术衍变而设计一种栽培方式即育苗盘种植。试验研究表明，最适的盘培方式为育苗盘高度为1cm，栽培槽上再铺设6层无纺布用于养鱼废水的过滤、保湿，另外，栽培槽的坡度设计在2％—8％之间。

The results showed that the seed germination rate decreased gradually as the NaCl concentration increased .The seed germination rate and imbibition rate was lowest when the seeds were treated with 200 mmol·L~(-1)NaCl; the recovery rate of ungerminated seeds in 150 and 200 mmol·L~(-1)NaCl had no significant difference with the control and it was more higher than the seeds in100 mmol·L~(-1)NaCl.

的种子，逐日测定萌发率、吸胀率；5 d、10 d后测定种皮和种胚的Na~+、K~+含量；培养15 d后，将含有NaCl的营养液中未萌发的种子分别转入1/4 Hoagland营养液继续培养，测定解除盐胁迫后种子萌发的恢复率；以探索不同浓度的NaCl处理对海滨木槿种子萌发及其种皮和胚的Na~+、K~+含量的影响。

In the present study a solution culture method was developed to test the effects of mycorrhiza formation on organic acids.

本试验改固体培养基为营养液培养基，采用静止的培养方法，在培养四个月时发现，萌发孢子的菌丝生长良好，菌丝已经侵染了根段，形成了根内菌丝，同时也观察到大量辅助细胞的存在；培养六个月后，形成了成熟的新孢子，说明营养液静止培养菌根共生联合体的方法是成功的。
