Research On The Current Situation And Countermeasures Of Environmentally Friendly Production Of Rose Hybrida

Rose hybrida is one of the largest cutting flowers in China with the largest production acre and trading volume.It always has being developed in the world.The purpose of the research on the environmentally friendly production of Rose hybrida is to solve the environmental pollution problems which caused by improper using and handling of the fertilizer,the pesticide and the waste in the production process,and also to protect the ecological environment.In this research,we studied the standards,requirements and mechanisms of environmental certification which have been approbated by the International Certification Body,and took the Dutch Floriculture Environmental Program MPS-ABC as the representative to analyze the main certification requirements and scoring criteria,then researched the use of pesticides,fertilizers and dispose of waste during the production of Rose hybrida in Yunnan Province.And we also finished the research on "the influence of different levels of Bacillus subtilis(Y1336)WP treatment on high-efficient production of Rose hybrida".The main results are as follows:(1)Through the study,the meaning of the Floriculture Environmental Program became more clearly to the main international environmental certification program,such as GLOBALGAP、Florverd、FLP、FFP、EU Ecolabel、EKO、MPS,etc.According to the MPS-ABC,we got the key themes about the environmental certification requirements and knew how to score by the Certification Institution to participates.(2)Through the research on some representative enterprises which plant the Rose hybrida mainly in Yunnan Province,it was known that the main environmental pollution problems which caused by the use of pesticides,fertilizers and dispose of waste during the production of Rose hybrida in Yunnan Province.Some suggestions on the schemes of recommended fertilizers and pesticides and also the management measures about the waste in the production are given.(3)The efficacy of 1 billion/g Bacillus subtilis(Y1336)WP diluted 400 and 600 time in controlling powdery mildew of Rose hybrida were 74.71%and 72.16%respectively,which showed that this biological agent had excellent effect in controlling powdery mildew of Rose hybrida;and the efficiency of 1 billion/g Bacillus subtilis(Y1336)WP diluted 600 times in improving the absorption and utilization of fertilizers was the best,which was significantly better than the another two treatments and the blank control.Considering the control effect and agent costs,it is recommended to use the level of 1 billion/g Bacillus subtilis(Y1336)WP 600 times in production of Rose hybrida,for at least 2 to 3 times which the interval of 7 to 15 days once.That will be friendly to environment.
