1, sorghum straw can't be fed to sheep because it is too hard, there are spiders on sorghum leaves and the nutritional value of sorghum straw is not high. 2. Sorghum straw can be processed into fertilizer, feed, energy, raw materials and matrix. Straw can be returned to the field when it is processed into fertilizer, can be fed to sheep and livestock when it is processed into feed, can be converted into biomass energy when it is processed into energy, can be made into textile raw materials, industrial raw materials and building materials when it is processed into substrate, and can reduce the production cost of edible fungi.

1. Why can't sorghum stalks be fed to sheep?

1, sorghum straw is hard, and things that are too hard are not suitable for sheep to eat.

2. There is a very small poisonous spider growing on the sorghum leaves in summer. Because this spider is relatively small, it is not easy to be found. Sheep will be poisoned after eating the spider and sorghum leaves together, and even die in severe cases.

3. The nutritional value of sorghum straw is average, and sheep can't get enough nutrients after eating sorghum straw.

Second, what can sorghum straw be processed into?

1, fertilizer

Straw can be used as fertilizer to return to the field, which can improve the soil and increase the yield of the soil by at least 10% per mu. However, it is difficult to plough the straw into the soil. Even if the pear ploughing is successful, the straw strands in the furrow may be exposed in the next tillage, which will affect the root growth of crops. The methods of straw returning to the field mainly include mulching or crushing, high-temperature fermentation and composting, livestock returning to the field after abdomen and putrefying agent returning to the field.

2. Feed

Straw contains a large number of non-starch macromolecules, which can improve its palatability and nutritional value after processing. The main processing technologies of straw include direct crushing, green storage mechanization, microbial fermentation, high-efficiency biochemical protein, ammoniation technology and thermal spraying technology.

3. Energy

Straw can be converted into energy, which mainly depends on straw gasification. In addition, straw can also be used to process briquette fuel and make gas. Straw resource is an important part of biomass energy, and biomass accounts for 14% of the total energy consumption in the world.

4. Raw materials

Straw can be used as raw material. When used as textile raw materials, rayon and rayon can be made. As industrial raw materials, products such as furfural, maltose, wine and xylitol can be produced. As a building material, it can be used as a substitute for brick, wood and other materials, and as a building material, straw has a very high cost performance.

5. Matrix

When straw is used as substrate, it can increase the source of raw materials for the production of edible fungi and reduce the production cost. Mushrooms such as Pleurotus ostreatus, Lentinus edodes, Flammulina velutipes and Coprinus comatus have been cultivated with straw matrix.
