Method for producing functional organic fertilizer by using trilobe wedelia

Abstract

The invention discloses a method for producing functional organic fertilizer by using trilobe wedelia. The functional organic fertilizer is prepared from the trilobe wedelia and organic raw materials by anaerobic fermentation, aerobic fermentation and ageing in the presence of composite fermentation bacteria and soluble sugar. Counted by the mass of dry basis, the trilobe wedelia accounts for 5-40 percent of the total mass of fermented fertilizer and organic raw materials accounts for 60-95 percent of the total mass of the fermented fertilizer. The organic fertilizer produced by the invention has the efficacy of killing ampullaria gigas and provides a treatment path for removing plant residues of the trilobe wedelia; the harm of the trilobe wedelia to crops is reduced, and the harm of harmful bacteria and mould to roots of the crops is effectively reduced.

Description

【Technical field】 [0001] The invention relates to a method for preparing a functional organic fertilizer, in particular to a method for making a functional organic fertilizer by using Wedelia trilobata, belonging to the technical field of agricultural fertilizers. 【Background technique】 [0002] Wedelia trilobata (Wedelia trilobata), introduced in Baidu Encyclopedia as: Asteraceae Wedelia plant, perennial herb, native to tropical America, widely naturalized in tropical regions of the world, mainly distributed in Hong Kong, Guangdong, Hainan, Taiwan, Fujian (Southern China) ), which has been listed as one of the "100 most harmful invasive alien species in the world". [0003] Wedelia trilobata is a perennial herb with strong adaptability. It can grow in different soil types. It can tolerate drought and humidity. It can tolerate low temperature of 4°C. It grows prostrate on flat ground and gentle slopes, and can hang on steep slopes. Cutting off branches or covered with soil ...

Problems solved by technology

[0004] Wedelia three-lobed was introduced and cultivated as a ground cover in the 1970s. At present, it has escaped and become a garden weed in some places in South China. It often grows in patches, encroaching on grasslands and wetlands, and crowding out native plants, making it difficult for other plants to grow in the patches of three-lobed weeds. Wedelia spp.

[0005] From the perspective of environmental phenomena, it is difficult to see other crops in the flakes of Wedelia trilobata. At the same time, research has found that the extract of Wedelia trilobata can inhibit the germination of peanut seeds. Other experiments have also shown that it has certain effects on other crops. Inhibition, although those crops can adapt to these inhibitory crops and return to normal, but the inhibition is still evident in the growing season
