Abstract

The invention discloses technology for cultivating barley pests by using straws, which relates to the technical field of schemes for solving the technical problems of processing of ensilaged straws and cultivation of the barley pests. The straws are regarded as wastes by common people, and even if useful sometimes, are only scattered on farmlands or deeply buried as fertilizers or combusted in situ so as to cause pollutions to the air and water sources. Under the guidance of agricultural specialists of the Beijing academy of agricultural sciences, multiple useful attempts are made and scientific data is finally mastered by the repeated groping and practicing of engineering technical personnel. Comparison between each index of insects actually cultivated by straw silages and the corresponding indexes of the insects cultivated by ordinary feeds shows that the survival conditions of the insects cultivated by the straw silages are remarkably improved, particularly that crude protein content is increased by about 10 percent and that amino acid and trace element technical indexes are both remarkably increased. Therefore, the ensilaged straws ideally serve as feeds for the insects instead of a part of wheat bran. In a processing scheme, the straws can be processed in situ or transported to a base for processing; and in the processing and transportation processes, natural disasters such as rain, snow, wind and the like are required to be prevented, and phenomena such as mildewing, deterioration and the like are more required to be prevented. The straw silages are mainly used for cultivating the barley pests.

Description

2. according to power 1 described insect mixed fodder, it is characterized in that: the proportioning of its supplementary material is: edible straw 60%---80%, and wheat bran 10%---20%, corn flour 5%---10%, worm powder 1%---2%, salt 0.3%---0.4%, other mineral matters etc. 0.2%---0.3%.

3. require described insect mixed fodder according to power 1, it is characterized in that the probiotics that is added has lactic acid bacteria, saccharomycete, bacillus, filamentous fungi, bacterial classification to account for 0.2% of total forage volume through expanding after numerous---0.3%.

4. according to power 1 requirement, the expanding propagation method of beneficial bacterium: selection function type biological inoculum, join with corn flour, brown sugar and add 150% clear water, pack into after fully mixing in the airtight container, fermentation is cultivated, 25 degrees above zero---and 30 degree need about 7 days, and 30 degree above freezing---35 degree need 4 days, the success standard: color yolk, smell fruit fragrance can be stand-by.

5. require described insect mixed fodder according to right 1, it is characterized in that the fish meal that is added substitutes with the worm powder.

6. one kind requires 1 as power 1---and the preparation method of 4 described insect mixed fodders is characterized in that comprising step:

(1) selection of supplementary material and proportioning: choose following raw materials by weight percentage pulverizing, standby:

Raw material: do not have the edible straw 60% that goes mouldy---80%;

Auxiliary material: wheat bran: 10%---20%, corn flour: 5%---10%, the worm powder: 1%---2%, salt: 0.3%---0.4%, other mineral matters: 0.%---0.3%, beneficial bacterium material: 0.2%---0.3%.

(2) processing of supplementary material: affiliated raw material is pulverized (particle diameter: 0.5---1cm) stand-by;

(3) mix: will add the proper amount of edible clear water in the described supplementary material,

The total forage volume 15% of water accounts---20%, each water addition determines according to the straw water content.Supplementary material fully stirs standard after mixing: held group with hand, vibrations are promptly loose and are as the criterion.

7, require described insect mixed fodder preparation method according to power 6, described functional form biological inoculum is lactic acid bacteria, saccharomycete, bacillus and filamentous fungi under it is characterized in that.

8, require the preparation method of described insect mixed fodder according to power 6, it is characterized in that containing albumen and amino acid lipid composition than higher edible stalk, corn flour, wheat bran and worm powder.

9, require the preparation method of described insect mixed fodder according to right 6, it is characterized in that the using method and the consumption of edible straw accounts for 60% of total forage volume---80%.

Background technology:

Detect proof through science: straw be rich in amino acid trace element and multivitamin, the barley worm has stronger cellulolytic ability in addition, in the worm sand of culturing, crude fibre has degraded 100%, lignin degradation 20%, and protein content has brought up to 7% by original 2%, and lipid has also increased more than one times.And the ensiling straw is easy to pulverize, smell fragrance, and good palatability can significantly improve barley worm feeding effect, and dead meal shines to become after the dry grinding can make mixed feed in proportion, can reduce the feed cost of culturing the barley worm greatly.

In recent years, after gathering, whole district crops all produced a large amount of straws, if the untimely processing of these waste straws, assorted bacterium is infected everywhere diffusion, serious environment pollution. and since straw be in each mountain area, the farming district, the every household decentralized management, have plenty of in the very inconvenient mountain area of traffic, if difficulty of governance is bigger. these straws through certain processing, are so both saved production cost, administered environmental pollution again. inquire at carry out technology with the utilization of straw secondary.

According to Fangshan District and periphery kind grow the incomplete statistics of professional cooperative society, after these regional annual crops are gathered, crop stalk can reach about 2000 tons, if can consume 2 kilograms of straws by 1 kilogram barley worm, these discarded straws can be cultured the barley worm and can be cultured 1000 tons of barley worms so, create 1,500 ten thousand yuan of economic benefits.Inference thus, nearly about 16000 tons of the waste straw of eight suburban countries and districts in Beijing whole years, the straw comprehensive utilization can be to plant grows annual 1.2 hundred million yuan of the economic benefits that produce in family, if this project is generalized to the whole nation, will supports the peasant to tradition and bring abundant, considerable income.

In sum, the straw utilization is a project that contributes to contemporary times and brings benefits for future centuries, if this project can be promoted in national rural area, will bring three following big advantages:

1, solves the contamination hazard that causes to rural environment of waste straw, make this rural area tradition plantation project bring into play bigger effect, found a new road for solving rural migrant worker's employment.
