采用大棚、温室栽培,是充分利用土地,提高土地经济效益的有效途径。但是由于受建造条件的限制,给轮作和排茬带来了困难。特别是黄瓜栽培。重茬后,很容易患枯萎病。这种病原菌生命力特别强,能在20厘米厚的耕层土壤中存活5～6年,有的可高达10年以上。特别是重茬黄瓜发病更盛。因此,科学合理的解决大棚、温室黄瓜的重茬问题,是提高大棚、温室黄瓜产量和经济效益的关键环节。 The use of greenhouses, greenhouse cultivation, is an effective way to make full use of land, improve land economic benefits. However, due to the restriction of construction conditions, difficulties were caused to the rotation and stubble. Especially cucumber cultivation. After repeated cropping, it is easy to get blight. The vitality of this pathogen is particularly strong, can survive in 20 cm thick topsoil 5-6 years, and some up to 10 years. In particular, crop cucumber disease more prosperous. Therefore, scientifically and reasonably solving the problem of stubble in green house and greenhouse cucumber is a key link to increase yield and economic benefits of greenhouse and greenhouse cucumber.
