摘要
以桶式无土栽培Ⅱ型装置为对照,研究和比较了两种不同桶式无土栽培新装置在番茄栽培上的应用效果,结果表明:在桶式无土栽培Ⅰ型新装置和Ⅱ型新装置栽培下,番茄植株生长健壮,产量提高。Ⅰ型新装置栽培下番茄植株有大约25%的根系在土壤中生长,75%的根系在装置内生长,且在株高、茎粗、鲜重、根系活力、果实中可溶性糖含量、单株产量等生理指标以及营养液的利用上表现较优,而在Ⅱ型新装置栽培下番茄植株有大约15%的根系生长在土壤中,85%的根系生长在装置内Ⅰ。型新装置果实Vc含量、有机酸含量以及单株结果数等生理指标表现较好,综合比较,Ⅰ型新装置更有利于植株根系的生长和果实品质的改善。
Using the tubbish soilless cultivating device Ⅱ as control, the application effect of the two new tubbish soilless cultivating devices were studied and compared in this article. The results showed that the growth of tomato plants were vigorously and the yield were increased by using the new tubbish soilless cultivating device Ⅰ and Ⅱ. Under the new tubbish soilless cultivating device Ⅰ, 25% of the tomato plants roots were grown in the soil and the other 75% were in the device, and the Culm height, Culm diameter, fresh weight, root activity, soluble sugar content in fi'uit, single plant yield and the utilizing of nutrition liquor of the plants were better than control and new device Ⅱ. However, under the new tubbish soilless cultivating device Ⅱ, 15% of the tomato plants roots were grown in the soil and the other 85% were in the device, the Vc, organic acid contents and the single plant yield were better. It Could be conclude that the root growth and fruit quality improvement were better in the new soilless cultivation device.
