Problems solved by technology

[0002] my country produces nearly 600 million tons of straw every year, of which about 70% is consumed as a form of living energy, less than 8% is fed to livestock after treatment, and the other part is returned to the field in the form of fertilizer, causing environmental pollution and energy loss
The content of lignin, cellulose and hemicellulose in the fermented straw obtained by this method is low, and the activity of filter paper carbohydrase, CMC enzyme, amylase and protease is high, but the effect of the straw prepared by it is not ideal

Embodiment 1

[0030] The processing of embodiment 1 corn stalks

[0031] A method for processing stalks, comprising the steps of:

[0032] (1) Straw steam explosion pretreatment:

[0033] The crushed corn stalks are kept under pressure of 3.0MPa for 150s, and then the pressure is suddenly released for blasting pretreatment. The processed samples were naturally air-dried for later use;

[0034] (2) Fermentation of corn stalks:

[0035] There were 4 treatment groups in the test, corn stalk group (control group 1), corn stalk + fermented liquid group (control group 2), corn stalk treated by the method disclosed in CN102077903A (control group 3), and the patent blasting corn stalk + fermentation Liquid group (test group), 6 repetitions in each group. They were cultured in a constant temperature incubator at 30°C for 7 days, and samples were taken every 24 hours for determination of relevant indicators.

[0036] The physical and chemical indicators of determination include: dry matter, crud...

Embodiment 2

[0040] Embodiment 2 broiler chicken feeding test

[0041] 200 28-day-old broiler chickens were randomly divided into 4 groups, respectively full-price compound feed group (control group 1), corn stalk+fermentation liquid group (control group 2), corn stalks treated by the method disclosed in CN 102077903A (control group 3 groups), the application patent blasting corn stalks+fermentation liquid group (test group), 50 in each group. Control group 1 was fed full-price compound feed, control group 2 used fermented corn stalks instead of 5% full-price compound feed, control group 3 used corn stalks treated with CN 102077903A to replace 5% full-price compound feed, and the test group was fermented with blasting pretreatment Corn stalks were substituted for 5% full-price compound feed, and the test period was 14 days.

[0042] After feeding, the animal production performance indicators are as follows:

[0043] After the test, accurately record the feed consumption, and calculate th...

Embodiment 3

[0056] Embodiment 3 Fat pig feeding test

[0057] A total of 160 healthy and fattening pigs with a weight of about 25 kg were selected and randomly divided into 4 treatment groups, namely the full-price compound feed group (control group 1), corn stalk + fermentation liquid group (control group). 2 groups), corn stalks treated by the method disclosed in CN 102077903A (control group 3), the patented blasting corn stalks+fermentation liquid group (test group), each treatment group had 4 replicates, and each replicate had 10 pigs. Control group 1 was fed full-price compound feed for growing and finishing pigs, control group 2 added 10% fermented corn stalks to the full-price compound feed, and control group 3 added 10% corn stalks treated with CN102077903A to the full-price compound feed. The group added 10% blasting pretreated fermented corn stalks to the full-price compound feed, and the test period was 30 days.

[0058] After feeding, the animal production performance indicat...

Abstract

The invention relates to the field of straw treatment, mainly relates to a method for pretreating straw through steam, and in particular to a straw treating method and application thereof. The method comprises the following step of performing steam explosion pretreatment on the straw: performing steam explosion pretreatment on crushed straw, and after treatment, naturally airing the pretreated straw for standby application, wherein the steam exposition pressure is 2.8-5MPa, and the dwell time is 80-180s. According to the method disclosed by the invention, firstly the steam explosion pretreatment on the straw is performed in a specific manner, so that the degradability and the utilization rate of the straw are improved; then the straw after the explosion pretreatment is treated through fermentation, and the fermented straw is used as an animal feed, so that the problem that a great deal of straw is stacked is solved, and the breeding profit of animals is also increased.

Description

technical field [0001] The invention relates to the field of straw treatment, in particular to a method for steam pretreatment of straw, and in particular to a straw treatment method and its application. Background technique [0002] About 600 million tons of straw are produced in my country every year, of which about 70% are consumed in the form of living energy, less than 8% are fed to livestock after treatment, and the other part is returned to the field in the form of fertilizer, causing environmental pollution and energy loss. With the continuous development of animal husbandry, the annual supply gap of pasture feed in my country has reached 280 million tons, and 600 million tons of straw resources are urgently waiting to be treated every year. At present, the bad disposal of a large amount of straw, such as incineration, seriously affects the air quality and causes a large number of If it is directly buried in the field, it will destroy the soil structure in the long ru...
