Abstract

The invention provides an earthworm cultivating method which is characterized by comprising preparation of earthworm beds, inoculation of earthworms, management and harvest of adult earthworms. Drainage ditches are arranged among the earthworm beds. Pedestrian paths are arranged on two sides of each earthworm bed. The cross section of each earthworm bed is designed to be a trapezoid. Water conveying pipelines are laid so that a humid growing environment for the earthworms is ensured, the environment of the upper portion of each earthworm bed is more humid and softer than that of the lower portion of each earthworm bed, automatic separation of the adult earthworms and young earthworms is achieved, sundry separating work in a later stage is avoided, and working efficiency is improved. The adult earthworms and the young earthworms grow separately, cultivating space is utilized sufficiently, and population competition is avoided to some extent. The adult earthworms are large in size, bright in color, high in spawning rate and high in high quality protein level, and therefore improvement of yield and quality of the earthworms is facilitated.

Description

A kind of earthworm culture method

Technical field

The invention belongs to animal-breeding technical field, particularly relate to a kind of earthworm culture method.

Background technology

Earthworm is a kind of multifunctional bio resource, and in earthworm body, 70% is all protein, is high-quality high protein source.Also containing the multiple enzyme with antibacterial action in earthworm body, can develop biopesticide, biological veterinary, biological organic fertilizer etc., its added value of product is high, environmental protection.Earthworm can also research and develop plurality kinds of health care food and animal protein feed, can reduce costs, and improves product quality.Therefore, earthworm is that a kind of cost is low, the reliable animal protein of highly effective and safe.And the polypeptide of wherein liquid extraction, there are growth promotion and antibacterial effect.

Current cultivation earthworm, is generally by the animal wastes such as cow dung, pig manure and straw, straw etc. are laid on soil for feed or pile fermentation cultivates, and this breeding way animal wastes usage amount is large, but it is few to go out earthworm, and the lethality of earthworm is high.The one-tenth earthworm individuality extracted after cultivation is little, and body surface color and luster is bright-coloured not, and the high-quality protein rate wherein contained is low, and the earthworm of traditional cultural method results often size all mix, the later stage is separated cumbersome, is unfavorable for increasing work efficiency.

Summary of the invention

In order to solve Problems existing in known technology, the invention provides that a kind of output is high, quality high-quality, the earthworm culture method that can effectively increase work efficiency.

The present invention for solving the technical scheme that in known technology, Problems existing is taked is:

A kind of earthworm culture method, is characterized in that comprising the following steps:

1) earthworm bed is prepared: select near water source, draining is convenient, ventilate, prepare earthworm bed away from the spacious location in urban district with cow dung or pig manure, described earthworm bed is cross section is trapezoidal rectangular ridge, described earthworm height of bed 1-1.5m, long 40-60m, bottom width 1-2m, lower bottom width 1.5-3.5m on trapezoid cross section, the spacing 3-5m of adjacent earthworm bed, sets up sunshade above earthworm bed, at earthworm bed top laying water pipes, described aqueduct offers hole for water spraying;

2) earthworm inoculation: earthworm kind rendered in the middle part of earthworm bed, earthworm kind injected volume is 0.3-0.8kg/ ㎡, and hole for water spraying is regularly sprayed water, keeps earthworm bed humidity to be 60%-80%;

3) manage: regularly inspect, note earthworm growth, breed and lay eggs, night lights is thrown light on, and prevents earthworm from fleeing;

4) gather in the crops into earthworm: through the raising of 30-40 days, earthworm grew up to, lay earthworm cloth at earthworm bed top and be extracted into earthworm, after going out earthworm, with cow dung or pig manure, earthworm bed is reduced to original trapezoidal rectangular ridge again.

Can be provided with the drain ditch of wide 0.5-1m between described adjacent earthworm bed, earthworm bed both sides are provided with wide 1-2m walkway.

Described hole for water spraying is evenly distributed on aqueduct both side surface, and the spacing 0.2-0.3m of arbitrary neighborhood hole for water spraying.

Beneficial effect of the present invention is: earthworm bed cross section is designed to trapezoidal, and the aqueduct that earthworm bed is laid, both ensure that the growing environment that earthworm is moistening, also earthworm bed top environment softness more moistening than bottom environment is made, when in the middle part of earthworm kind renders to earthworm bed, earthworm kind grows and breeds in the middle part of earthworm bed, one-tenth earthworm after breeding moves to earthworm bed bottom under the driving of self life habit, the young earthworm that breeding produces then moves to earthworm bed top under the driving of life habit, be embodied as earthworm to be thus separated with the automatic of young earthworm, avoid the mask work that the later stage is numerous and diverse, improve operating efficiency, become the separately growth of earthworm and young earthworm, make full use of breeding spaces, avoid Species Competition to a certain extent, become earthworm individuality large, bright in colour, spawning rate is high, and high-quality protein content is high, is conducive to the seed output and quality improving earthworm.

Embodiment
