Effects of Enteromorpha prolifera composting on yield and quality of Chinese cabbage

The composting experiment was carried out with the high-temperature compost technology by using the Enteromorpha prolifera and corn stalk as main material.The results indicated that the compost of Enteromorpha prolifera + corn stalk +EM lasted the longest time about 19d above 50℃,which was better than chicken manure compost.The organic substance-decomposition maturing agent increased the pile temperature rapidly,which mainly maintains at the stage of mesophilic fermentation.The Enteromorpha prolifera compost had obvious effect on the yield and application little influence on the quality of Chinese cabbage.Its fertilizer efficiency was similar with chicken manure compost.The application of Enteromorpha prolifera compost could reduce the amount of chemical fertilizer to avoid nutrient leaching loss and environment pollution.But excessive application of compost could reduce pH and increase salt content in soil.Therefore,the Enteromorpha prolifera compost application should be based on soil physical and chemical properties in vegetable production.The amount of compost was generally not more than 11.25 t/hm2,while dry compost application 5.6 t/hm2for basic fertilizer.
