Problems solved by technology

[0003] Rice straw is mainly composed of cellulose, hemifiber, etc. Its C / N (carbon / nitrogen) ratio is generally (60-100) / 1, which is difficult to decompose, has poor palatability, and low nutrient utilization rate, so it is difficult to be digested. Feed by cattle, sheep and other livestock

Embodiment 1

[0024] (1) In the Shenyang rice area, the rice straw after being fully fed into the rice harvester to harvest the grains is used as raw material. If the straw is not harvested in time and dried, the moisture content will drop to 40% (crude protein 8%, crude fiber 55%), It is necessary to adjust the moisture content to about 60% for collection;

[0025] (2) Dissolve the bacterium-enzyme compound preparation in an appropriate amount of brown sugar that has been boiled and inactivated, and then the cooling temperature does not exceed 40°C in warm water; the mass ratio of the preparation to the sugar is 1:5, and the preparation and the sugar water are stirred evenly and then sealed for 3 days to activate the starter. use;

[0026] (3) Dilute the mixture of sugar water preparation with water 1:10, add it to the liquid storage box of the micro-storage baler, and use the rice straw micro-storage baler to carry out straw picking, fermentation agent spraying, bundling, and plastic seal...

Embodiment 2

[0031] (1) With the Shenyang rice field, the rice straw that is pulverized after fully feeding the rice harvester to harvest the grain is used as raw material, and the moisture content of the raw material is 65% (crude protein 9%, crude fiber 55%) to be collected;

[0032] (2) Dissolve the bacterium-enzyme compound preparation in an appropriate amount of brown sugar that has been boiled and inactivated, then the cooling temperature does not exceed 40°C in warm water; the mass ratio of the preparation to the sugar is 1:4, and the preparation and sugar water are stirred evenly and sealed for 3 days to activate the starter. use;

[0033] (3) Dilute the mixture of sugar and water preparation with water 1:8, add it to the liquid storage box of the micro-storage baler, and use the rice straw micro-storage baler to carry out straw picking, fermentation agent spraying, bundling, and plastic sealing operations; straw feeding speed 48kg / min, starter spraying speed 2.0L / min, round bale d...

Embodiment 3

[0038] (1) With the Shenyang rice field, the rice straw that is pulverized after fully feeding the rice harvester to harvest the grains is used as raw material, and the moisture content of the raw material is 50% (crude protein 9%, crude fiber 57%) to be collected;

[0039] (2) Dissolve the bacterium-enzyme compound preparation in warm water that has been boiled and inactivated with an appropriate amount of brown sugar, and the cooling temperature does not exceed 40°C; the mass ratio of the preparation to the sugar is 1:6, and the preparation and the sugar water are stirred evenly and sealed for 3 days to activate the starter use;

[0040] (3) Dilute the sugar water preparation mixture with water at a ratio of 1:15, add it to the liquid storage box of the micro-storage baler, and use the rice straw micro-storage baler to carry out straw picking, fermentation agent spraying, bundling, and plastic sealing operations; straw feeding speed 48kg / min, starter spraying speed 3.4L / min,...

Abstract

The invention relates to a method for preparing a rice-straw coarse feed and belongs to the technical field of comprehensive utilization of rice straws. The specific method comprises the steps: adjusting the moisture content of grain-harvested green and yellow rice straw raw materials to 50% to 65%; dissolving a bacterial enzyme compound preparation in brown-sugar-added boiled-deactivated warm water; carrying out uniform stirring, and then, carrying out closing for 3 days to activate a fermentation agent for later use, wherein a mass ratio of the bacterial enzyme compound preparation to brownsugar is (1: 4) to (1: 6); carrying out straw pick-up, fermentation agent spraying, bundling and plastic packaging operations by using a rice straw microbial-ensilage baler; ensuring that 0.15g-0.17gor 1.5*10<5>CFU/g to 1.7*10<5>CFU/g of bacterial enzyme compound preparation is added into fresh straws per 1kg, and each circular straw bale formed after bundling has a diameter of 80cm-120cm, the height of 80cm-120cm and the density not lower than 450kg/m<3>; and placing the baled straw feed in fields for natural fermentation, and forming the coarse feed after the fermentation is completed. Therice-straw coarse feed prepared by employing the method has the advantage that physical and chemical properties of the rice straws are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of rice straw comprehensive utilization, in particular to a preparation method of rice straw roughage. Background technique [0002] The annual output of rice straw in my country reaches 200 million tons, and the current utilization methods include: 1) fuel (but the combustion value is very low); 2) raw materials such as papermaking and straw rope: due to the cost factor of picking and transportation, the economic benefits are very small; 3 ) Feed: poor palatability, very low feed intake rate of livestock. Integrating all utilization methods, the utilization rate is only about 10%, and the remaining straw is either burned or rotted naturally, which wastes resources and pollutes the environment. This phenomenon is especially serious in the northern rice areas of my country. At the same time, with the rapid development of animal husbandry, the demand for feed is increasing year by year, and the season of hay i...
