| 摘 要： | 对连作８年、４年和２年的大棚番茄的根系活力及其品质进行研究。其结果表明，连作２年和４年的大棚番茄根系活力无显著差异，而连作８年与２和４年的大棚番茄根系活力分别达到α＝０．０１和α＝０．０５的显著水平。对各连作年限的不同时期的根系活力研究结果表明，连作８年与２和４年的大棚番茄根系活力的差异主要表现在采收初期和采收末期。对不同连作年限的大棚番茄进行品质分析，结果表明，连作８年的大棚番茄品质明显变劣。

| Abstract: | The vitality of root systems and their qualities were studied in the plastic house tomatoes continuously cropped for 8, 4, and 2 years. The results indicated that: There were not significant differences for the root vitality of the plastic house tomaties between 2 and 4 years with continuous cropping. But the root vitality of the plastic house tomatoes reached significance levels of α=0 01 and α=0 05 between 8 and 2 year or 8 and 4 year of continuous croppeng. The root vitalities of different period periods for continuous years were studied and the results indicated that the differences of the root vitalities of plastic house tomatoes between 8 and 2 year or 8 and 4 year continuous cropping carried out in the early and final stages of harvest. The quality analysis of plastic house tomatoes for different years of continuous cropping indicated that the quality for plastic house tomatoes were in decaying significantly in 8 year continuous cropping |
