Effects of Hydrothermal Treatment Products from Pig Manure on Soil Properties and Growth of Chinese Cabbage
In order to explore the ways of pig manure waste recycling,the hydroheat treatment products of pig manure under different temperatures were used as additives,the soil characteristics were studied,and the improvement effect of hydroheat products on soil was verified through the cabbage planting experiment.The results showed that compared with CK,at 49 days of planting,each hydroheat treatment products of pig manure treatment group significantly reduced the pH,and the alkali nitrogen,effective phosphorus,quick potassium,organic matter and EC were significantly improved in all treatment groups,among which the alkaline hydrdyzed nitrogen,available phosphorus,available potassium,organic matter and EC increased by 29.10％,61.78％,22.94％,20.31％and 25.70％,respectively.At 60 days of planting,the fresh weight,biomass,single plant height,leaf area of single plant,root length,root weight and harvest index of Chinese cabbage all improved,among which the growth traits of ZF180 treated group were the best.Compared with the CK control group,the Chinese cabbage yield,aboveground biomass,single plant height,single plant leaf area,and root length increased by 225.17％,225.39％,61.50％,104.78％,and 90.67％,respectively.Therefore,180 ℃ hydrothermal treatment temperature is the optimal temperature for pig manure waste recycling.
