豬場生物發(fā)酵床墊料衛(wèi)生評價
[Abstract]:The culture technology of the fermentation bed in China is becoming more and more popular, and a large amount of padding is available every year. It is of great practical significance to study the cumulative dynamic and biological safety of the dunnage components and provide the basis for the rational resource utilization of the padding. This paper mainly studies the change of nutrient components and heavy metal enrichment and the effect of heavy metal enrichment in the use process of the fattening pig house fermentation mattress. The contents of water, total nitrogen, total phosphorus, potassium, calcium, iron and heavy metal elements (Cu, Mn, Zn) were measured by 5-point sampling method, and the contents of water, total nitrogen, total phosphorus, potassium, calcium, iron and heavy metal elements (Cu, Mn, Zn) were measured, and the different use time was studied. The method is used for evaluating the toxicity of the fermentation bed mattress material to the plant through the analysis and research on the decomposition degree of the fermentation bed mattress, The effect of heavy metal elements, such as Zn, on the residue of soil and plants. The main results are as follows: 1. The change of moisture content of the various components in the padding: the initial moisture content and the total moisture content in the padding gradually decrease with the use time, and after 18 months, the total water content is reduced to about 33%, and the adsorption water is gradually increased; and the difference between the water content of the different depth padding is not obvious. The content of total N in the fermentation bed was 993g/ kg-11.32g/ kg, and there was no significant difference (P0.05). The contents of Ca and Fe increased, and there was a significant difference (P0.05). The contents of total P, total K, Ca and Fe in the padding were in the range of 10. 10 g/ kg to 32. 03 g/ kg, 17. 60 g/ kg to 44. 17 g/ kg. The content of Cu, Zn, and Mn in the padding was 196. 74 mg/ kg-648. 82 mg/ kg. 1396. 95 mg/ kg-1937. 80 mg/ kg. 238. 87 mg/ kg-812.89 mg/ kg, respectively. The use time of the padding had a significant effect on the content of Cu, Zn, and Mn in the padding (P0.05). There was no significant difference in the content of Cu, Zn, and Mn between different depths (P0.05). The higher the use time of the padding, the higher the content of Cu, Zn, and Mn in the padding, the content of Cu and Zn in the padding with the time of over 6 months has exceeded the limit of the technical specifications of the national livestock and poultry manure. The toxicity of the fermentation mattress to the plant increases with the time of the use of the padding, and the GI value of the padding exhibits a generally upward trend. in which the GI value of the padding used for 18 months is more than 60%, and after the use of the padding for 12 months, the GI value of each layer is more than 50%, the padding is basically decomposed, and the toxicity to the plant reaches the level that the plant can resist. The effects of the addition of padding on the yield and quality of the Chinese cabbage and the soil safety were studied. The test results show that the addition of padding can significantly improve the yield of the Chinese cabbage and the content of the crude protein when the addition amount of the padding is less than 30%. When the addition amount is 30%, the yield of the Chinese cabbage and the crude protein content are the highest. In the case of excessive application of padding, the yield of the Chinese cabbage is reduced, and the content of the crude protein is not significantly increased. With the increase of the addition of the padding, the content of Cu and Zn in the Chinese cabbage shows a rising trend, which shows that the application of the padding of the pig farm can promote the absorption of Cu and Zn in the Chinese cabbage. At the same time, the increase of the addition of the padding can significantly increase the content of Cu, Zn and TN, TP and TK in the soil. The heavy metal content in the mixed soil increases with the addition of the padding in the soil. The test monitoring pig farm fermentation bed-bed material is decomposed after being used for 12 months, and the toxicity of the plant reaches the tolerance level of the plant seeds. However, as the time of use is prolonged, the heavy metal elements in the padding are gradually enriched, and the use time is over 6 months, and the organic fertilizer can not be applied to the farmland directly as the organic fertilizer. Therefore, when a fermentation bed is used for raising pigs, the service life of the padding is reasonably controlled; when the padding is processed, in order to improve the yield and the quality of the agricultural products, the safety risk of the soil is reduced, and the potential harm of the heavy metal content to the environment should be assessed, and the application rate of the padding is reasonably controlled. It is suggested that the characteristics of soil and organic fertilizer should be measured in the actual production, and the formula of organic fertilizer can be applied to ensure the safety of the crops and the ecological environment.
