不同种植模式对设施蔬菜土壤酶活性及枯萎病发生的影响研究

Effect of Culture Patterns on the Activity of Soil Enzyme and Blight of Greenhouse Vegetables in Ningxia

设施蔬菜由于其独特的种植模式,随着种植年限的延长,连作障碍问题十分突出。改变种植模式是解决连作障碍问题的一种既经济又有效的方法。通过研究得出,番茄—茄子和芹菜—番茄土壤中过氧化氢酶、磷酸酶、脲酶的活性整体较低,且植株田间容易发病,说明这种种植模式不利于田间种植。番茄—黄瓜、黄瓜—番茄这种模式还是比较好的,但也不能多年连续种植,还应该和其他作物如西葫芦、梅豆、月菊倒茬种植。

Because of special culture pattern of greenhouse vegetables, with planting life extending, consecutive monoculture problems have become more and more prominent. Culture pattern change is an economical and effective way to alleviate consecutive monoculture problems. By studying, the results showed that the plants cultivated in the pattern of tomato-eggplant or celery-tomato was highly sensitive to diseases because catalase, phosphatase and urease in soil had low activity.However, the patterns of tomato-cucumber and cucumber-tomato were better, which could not be planted for many years.These vegetables should be rotated with other crops such as pumpkin, plum bean and Chinese rose.
