笔者于1984年在无黄瓜栽培史的本所科研基地,对新建的228m~2温室和576m~2塑料大棚的黄瓜霜霉病发生情况进行了观察试验,证明北方春季生茬保护地黄瓜霜霉病当年即可严重发生。科学放风可减轻危害。 试验情况与结果 棚向东西,垄向南北;棚膜聚氯乙烯菜膜;底肥用腐熟马粪和鸡粪;品种为长春密刺。 黄瓜温室育苗及大棚生育期各设4个重复区(用塑料帐幕封严隔开)。大棚黄瓜生育期除自东至西间壁Ⅰ、Ⅱ、Ⅲ、Ⅳ4个区
The author in 1984 in the absence of cucumber cultivation history of our research base, the new 228m ~ 2 greenhouse and 576m ~ 2 plastic greenhouse cucumber downy mildew were observed and tested to prove the protection of spring in northern spring cucumber downy mildew That year can be severe disease. Scientific ventilation can reduce the hazard. Test conditions and results Shed to things, ridge north and south; greenhouse film PVC film; maturity with manure and chicken manure excrement; varieties of Changchun dense thorns. Cucumber greenhouse nursery and greenhouse growth period set up four repeat areas (sealed with plastic tent separate.) Greenhouse cucumber except during the growth period from east to west wall Ⅰ, Ⅱ, Ⅲ, Ⅳ4 district
