Research On The Agriculture Application Of Pyroligneous Acid And Mechanism

Pyroligneous acid is the organic product obtained from plants with dry distillation by the process of condensate, recovery and separation from natural gas mixture. Acids, alcohols, phenols, esters, carbonyl and furan by nearly 500 different compounds has been identified in the Pyroligneous acid. After a simple and fine process, on pyroligneous acid could be used in agriculture, industry, environmental protection, health and preservation of the areas of food processing and so on. It can also be used as the plant growth-promoting agent, the soil conditioner, the anti-bacterial agent, the insecticide, the repellent, the deodorizing agent, the feed additive, the organic fertilizer ferment in the agricultural production. It is safe, pollution-free, non-residue and with other advantages. It has great significant effect the on wasting vegetable resources, reducing carbon dioxide emissions, developing of organic ecological agriculture, and keeping the sustainable development of agriculture. This paper studied the effects and action mechanism of pyroligneous acid on panax ginseng, bulbus fritillariae ussuriensis, oyster mushroom, black forest mushrooms, and egg on the application. The control effect of pyroligneous acid and plant extracts with the use. The aim was to provide a scientific basis of pyroligneous acid liquid popularization and application in agriculture.A different dilution of pyroligneous acid foliar spray had different effects on different ginseng peace and bulbus Fritillaries. Appropriate dilution of the pyroligneous acid could promote the growth, increase production and improve the content of the role of ginsenosides. Ginseng spraying 300 times pyroligneous acid made the biomass, production and ginseng spooning content compared with the control respectively increased 9.97%,12.26% and 36.28%; bulbus Fritillaries spraying 200 times pyroligneous acid made the biomass, production and plant height compared with the control respectively increased 17.66%,14.47% and 13.69%; and have the effect of promoting root growth, enhancing root vigor, increasing chlorophyll content and photosynthetic rate, the promotion of N, P, K of the absorption. A higher concentration of pyroligneous acid could promote radial growth of ginseng and bulbuls fritillariae usuries. The measured values of leaf width, stem diameter and root thick (diameter) was higher than that of the control.The mechenism of pyroligneous acid to increase yield of panax ginseng and bulbus fritillariae ussuriensis is that it can stimulate more secretion of the roots, improve the microenvironment of the roots and promote the probagation of microorganism so as to improve the effectiveness of the nutritients and the absorption of the nutritient elements (N, P, K), as well as the synthesis of chlorophyl.Adding the different concentrations of pyroligneous acid to oyster mushroom and black forest mushroom cultivation compound had different effects on the mycelial growth and yield. High concentration of pyroligneous acid restrained the growth and increased the production of mycelial. The suitable concentration of pyroligneous acid could promote growth and increase the production of the mycelial. Adding the 0.05% pyroligneous acid into the oyster mushroom and the black forest mushroom cultivation compound, the mycelium growth rate was significantly higher than other treatments, and the yield compared with the control respectively increased 13.50%, and 12.67%; but both the total content of amino acids and the content of essential amino acids showed no significance.There were different effects on the egg production and egg quality along with different concentration levels of pyroligneous acid added into the layers feed. High concentration of pyroligneous acid would reduce egg production; white with 0.75% pyroligneous acid, egg production rate increased 4.03% and 2.14% compared with the control. The highest content of protein and calcium increased 10.85% and 14.75%, while the highest content of cholesterol decreased to 31.8%. Different treatments of pyroligneous acid have all cholesterol-lowering effects, but there was no significant effect on the trace elements Fe, Cu, Zn content.Pyroligneous acid with toxic plant extracts can improve the control effect on pest, the control effect increased with increasing the concentration of pyroligneous acid. From five kinds of plant extracts in the test, Datura metel extract used in conjunction with the pyroligneous acid was the best control effect on Pieris rapae. From nine plant extracts in the test, purslane extract used in conjunction with pyroligneous acid was the best control effect on cucumber angular leaf spot, the best control effect on powdery mildew was Rumex crispus extract, pyroligneous acid alone and with the tested plant extracts were mixed fertilizer to improve the yield and quality of cucumber. The effect of the low concentration of extract used for pest control was poor. It was difficult to use the higher concentration of the extracts in the test in practice. To study whether the pyroligneous acid and toxic plant extract used in conjunction has increased the efficacy of the role was the main purpose in this experiment. And how to reduce the concentration of extracts to be used will be researched in further study.
