Ornamental bonsai - potted banyan tree vitality, hardy drought-tolerant, evergreen, graceful, unique shape, with the effect of indoor air purification and high ornamental value. In recent years, the potted banyan production soon, the products have been widely exported to European and American markets in the Netherlands, the United States and other development in the vicinity of Zhangzhou, Fujian Province. Potted plants the banyan are fresh seedlings plant, the importing country or region in order to protect their own or the interests of the development of the flower industry in the region and flower growers, imported plants proposed strict quarantine inspection requirements, entry plant must not carry the soil and in vivo nematode roots and matrix soil or living nematodes detected, the entire cabinet will be asked to cargo fumigation or returned, destroyed, causing serious losses. Potted banyan mining exports generally unable to supply water and light container transport, great differences in the environment of such an environment with normal growth, leaf yellowing, loss and other problems will appear after 20 ~ 40d dark environment, serious affect ornamental potted banyan tree, reducing the value of the goods. Therefore, looking for the prevention and treatment of potted banyan root-knot nematodes Pharmacy and inspection and quarantine technology, control, storage and transportation of environmental conditions, potted banyan tolerance to the ability to extend the storage period, reduce deciduous rate, to maintain its ornamental increase its commercial value, The current problems to be solved. Potted banyan test materials, different substrate compositions screening, prevention and treatment of root-knot nematodes chemical screening, anti banyan leaves storage technology exports potted banyan system processing mode, a potted plant cultivation matrix characteristics, different the impact of pesticides on nematode control effect of different processing factors potted banyan storage characteristics, in order to get the mechanism to reduce the storage and transportation of export potted banyan deciduous extend potted banyan export storage and control of root-knot nematodes effective approach. The results are as follows: 1, the ratio T (580% coco peat 20% perlite), T6 (70% coco peat 30% perlite), T (775%, 20% perlite 5% coco peat peat), T8 (70 % 20% perlite 10% coco peat peat), T9 (65% coco peat 20% perlite and 15% peat), T10 (80% coco peat 20% perlite 5g aquasorb) and T11 (80% coco peat 20% perlite 10g aquasorb), suitable for plant growth bulk density, porosity, held water the pH and EC values ??and organic matter, the whole effect NPK NPK fast-acting, slow-K and other nutrients, is the ideal ratio combinations. 2, the storage temperature, culture medium, fertilizer, anti-drop Pharmacy potted banyan tree preservation as the main influencing factors, the results show that: the storage temperature 10 ° C, matrix ratio of 80% coconut flour bran 20% perlite 10g water agent (media aquasorb quality than 100:1), 100 times MACLEOD K fertilizer IRRIGATING 800ug / L Brassinolide lactone foliar spray can effectively reduce the rate of storage banyan leaves, the storage time 36d the case of deciduous rate at 16% or less. The optimal combination can effectively reduce the leaf plasma membrane permeability and MDA content, slowing the speed of degradation of osmoregulation substance, chlorophyll content and antioxidant protection mitigation activity decline and improve the storage capacity of resistance during delay banyan aging, reduce defoliation rate to meet the export requirements. Storage pre daily drop of 2 ℃ Storage Temperature the 36d storage after deciduous rate can effectively reduce. 3, the storage rate of banyan leaves its chlorophyll content, leaf plasma membrane permeability, MDA content, POD activity, CAT activity, soluble sugar content, soluble protein content correlation coefficients were above 0.7, these physical and chemical properties can be used as banyan anti-reference storage dark environment stress indicators, but these biochemical indicators and banyan anti the cryogenic dark environment capabilities and deciduous relationship needs further study. 4,2% Avermectin and 40% chlorpyrifos EC potted banyan matrix nematodes and root-knot nematode disease has good control, 100mg/Kg 2% abamectin treatment drugs after 15d matrix nematode control effect was 99.7% Drug 45d knot nematode disease control effect still reached 95.7%; carbofuran and the benefits Whisper the two granules Pharmacy nematodes are less than 50%, the root-knot nematode disease prevention effects are less than 70 %, significantly better than abamectin and chlorpyrifos; the use 100mg/Kg 2% avermectin IRRIGATING prevention knot nematode the banyan safety, no side effects, does not produce injury.
