BeiJing Bonsai tree

　　In response to some flowers of the horticulture sector requirements, the need for their own bonsai garden pest control on the views of governance issues. To this end, we are dedicated to the base of understanding of bonsai and flower growth, management, listen to the current occurrence of nematodes and other presentations, will now be made in the management of the program are as follows:
  
    1, floral arrangements on the main problems
  
    At present, the bonsai on the woody plants with a worm due to a direct impact on export markets, Although it has taken some of the traditional practices, has also achieved good control effect, but has made some of the roots of potted flowers and plants are affected, so that after the export of flowers Bonsai happen wither, leaves until death, after a comprehensive analysis of the following causes.
  
    1, the current approach taken by the main control
  
    At present the export of woody seedlings in Huanpen and exports before the pesticide should be handled, so that with a bonsai to absorb liquid and then export or Huanpen HKRAS exported. We believe that this method of control nematodes is a traditional approach, placing the density in a greenhouse situation can be used. But it also brought the following issues.
  
    (1) Use of pesticides for too long, resulting in phytotoxicity will directly affect the root growth, it has been reflected in seedling roots of black, which is the main reason for injuries caused by impact of the growth of seedlings.
  
    (2) No order for flowers, bonsai trees and tree species comparison trials, irrespective of species, the tree so that all use the same method, this would produce drug-resistant tree species poor phytotoxicity.
  
    (3) varieties of pesticides has not been a variety of tests, in addition to some types of pesticides can be used, although some had been registered, and some are not registered, use the existence of efficacy and residual and injury risk.
  
    2, the need to improve the views of
  
    (1), mainly by the soil-transmitted nematode, so wireless is the key measure of soil insects and therefore recommends that the current method from the cost of soil treatment, the effect on the plus to improve.
  
    (2) Increase the concentration of liquid and mixed the other pesticides, would affect the root growth.
  
    (3) The worm has been used in the case of dealing with agents should not be blindly use of other pesticides.
  
    (4) to reduce pesticide concentrations should also be made of different trees, different varieties of bonsai comparison tests, screening of different trees to make, different varieties of different frequency of use.
  
    (5) The search for new pesticides to deal with the worm. Recommended to conduct a different pesticides at different concentrations, different species and different tree order, at different times of the test. To determine whether to replace the existing pesticides to control nematodes.
  
    2, it is recommended the need to strengthen pest prevention and control of a few comments
  
    1, as soon as possible by experts to determine various types of bonsai pest control techniques for integrated observation and guidance, do not completely rely on themselves to explore. Do present a good job in technical reserves, to prevent "green barriers" impact.
  
    2, purchase the necessary equipment and observation rooms. Purchase the necessary equipment at the base, so that you can side of prevention and treatment of side effects observed.
  
    3, at home and abroad to collect bonsai cultivation, varieties and pest and disease control information, to improve the survival rate and growth rate of bonsai.
