| Abstract: |
| Experiments of plastic film and maize straw coving over winter for lily flower were carried out in Qingyang.Soil water consumes and ground temperature change characters were observed.The effects of different material coving on development period,growth and output of lily flower were analyzed.The results show that the plastic film coving can hold soil water,increase soil water use efficiency,as both the autumn precipitation and soil water are rich,as well as the winter air temperature is high and winter precipitation is little.That coving can increase ground temperature in spring,accelerate growth,and reduce the harm of spring drought,which is very useful for increasing production. |
