| 摘 要： | 为了探讨不同根区通气空间大小对设施番茄植株生长的影响,采用基质下部铺设拱形网架,通过设置3种不同网架高度(T1:15 cm、T2:20 cm、T3:25 cm),形成根区不同大小的通气空间,以无通气处理为对照,测定了生长期间的根区气体浓度、植株生长、果实产量和品质变化。结果表明:不同处理之间根区CO_2浓度变化幅度较大,其中CK的CO_2浓度最高(2.1%);而O_2浓度变化幅度较小,以T2处理为最高(19.3%);T2处理植株的长势在整个过程中表现最好,根系活力和硝酸还原酶都表现为;通气处理有助于干物质的积累,在生长后期T2处理表现出了较高的产量和营养品质。说明适宜的根区通气空间有利于改善番茄植株根区O_2和CO_2气体环境、促进番茄植株的生长和果实产量的增加。

| Abstract: | With the method of change the size of ventilation space of root-zone.In this paper,the effect of different root-zone environment on tomato was studied.The results showed that contents of CO_2 and O_2 in root-zone were significantly different among the four manners of ventilation,CO_2 content of CK treatment was the highest(2.1%),and O_2 content of T2 treatment was the highest(19.3%).T1 treatment had a high value in the aspect of root activities and NR;T2 treatment had the best yield and nutrition quality.To... |
