双垄全膜马铃薯套种豌豆对马铃薯生育期及病害的影响

摘要

在双垄全膜马铃薯套种针叶碗豆的栽培模式下,研究了其对马铃薯的生育期及病害的影响.结果表明,马铃薯在双垄全膜栽培条件下出苗、现蕾、开花及成熟都较露地有所提前.在病害方面,覆膜使马铃薯早疫病的发生加重,但对晚疫病的发生有很好的抑制作用.%Based on cultivation models of potato interplanting with pea by whole covering on double ridges with plastic films, the phenophase and diseases of potato were investigated. The results indicated that the periods of emergence, budding, flowering and maturity of potato in lands covered on double ridges with plastic films were earlier than those in open fields. And the model of potato-pea was an effective way to control the potato late blight, compared with the common sowing. On the other side, this model could increase the development of the potato early blight.
