Spartina alterniflora straw compost as well as preparation method and application thereof

Abstract

A spartina alterniflora straw compost comprises the following components in parts by weight: 500 parts of spartina alterniflora straw, 100 parts of dried cow dung, 15 parts of barley, 5 parts of rapeseed, 2 parts of gypsum powder, 10 parts of calcined lime, 12 parts of calcium superphosphate and 5 parts of urea. A preparation method for the spartina alterniflora straw compost comprises the following steps: adding cow dung, barley, coleseed, calcium superphosphate, calcined lime, gypsum and urea into spartina alterniflora straw, uniformly stirring, and conducting pasteurization; then supplying oxygen for fermentation at 48-52 DEG C, and placing for three days so as to finish fermentation. The spartina alterniflora is strong in reproductive capacity, threatens the global marine marsh native species and damages the ecosystem, so that control and utilization of the spartina alterniflora have important significances. The spartina alterniflora is a C4 plant, and belongs to plants with high carbon content, thereby having very important advantages on organic fertilizer formation.

Description

technical field

[0001] The invention relates to the field of agricultural technology, in particular to a compost of Spartina alterniflora straw and a preparation method thereof. Background technique

[0002] Spartina alterniflora is native to the United States and is a perennial salt marsh plant that grows in the intertidal zone. In the early 1980s, Spartina alterniflora was introduced into China for beach protection, bank protection, silting and land reclamation. The introduction of Spartina alterniflora once played a major role in protecting seawall safety, promoting economic development in coastal areas, improving ecological environment, and reducing disasters. made significant contributions. However, after more than 20 years of development, Spartina alterniflora has formed a community of 800,000 to 1,000,000 mu in coastal areas of my country. With the dominant community formed by this alien invasive species, it has brought a series of negative impacts to coastal areas. ...
