近年来,地膜覆盖技术在农业上应用十分广泛,取得了显著的早熟、优质、增产效果。但是将地膜覆盖应用在牡丹催花上,至今还未见报道。我们进行了多年试验,特别是1997年在菏泽地区农业高新技术示范园利用这项技术催牡丹花,收到良好效果,培育的近3000盆牡丹在春节开花时都是根深叶茂、花繁枝荣、花径大、花色艳,无异于春天正常季节大田所开的牡丹花(如图1)。我们做的地膜覆盖,不是把整株牡丹都盖在塑料薄膜下面。而是
In recent years, plastic film mulching technology is widely used in agriculture and achieved remarkable precocity, high quality and yield increasing effect. However, the application of plastic mulching flowers in the peony, so far has not been reported. We conducted many years of experiments. In particular, in 1997, Heze Prefecture Agricultural High-tech Demonstration Park used this technology to promote peony flowers and received good results. Nearly 3,000 peonies cultivated during the Spring Festival are deeply rooted and flowering branches Wing, flower size, flower color Yan, is tantamount to the normal spring season opened the peony flowers (Figure 1). The mulching we made did not cover the whole plant under the plastic film. Instead
