Rural straw utilization value.
China is a big agricultural country, farmers account for 80% of the number of people in our country, the planting of agricultural products is very high, corn stalk is the third largest crop after rice and wheat. China's cultivated land area is large, the amount of crops planted is high, the yield rate of corn is only about 25%, how to effectively develop straw resources, the use of these seemingly no straw, we also need to use effective tools.
The value of straw.
At present, the straw in the countryside is usually treated in two ways, incineration, return to the field, although these two ways have little value to use, but 85% of farmers are treated in this way, so there is no real value of straw. In fact, the use of straw can be used to process these materials into useful materials, so that straw can realize its own value.
Uses of straw.
According to the value of straw mentioned above, the various uses of straw directly affect the value of straw, so what is the big use of these small straws, we can take a look at it first, straw can be processed into fuel rods after crushing, which belongs to a smokeless and pollution-free environmental protection material, the material is widely used for heating, cooking vegetables, etc., straw can also be used as a material for poultry breeding, biogas digester, papermaking, power generation, etc.
Crushed straw materials after crushing and processing of straw materials, see above can be used in a variety of industries, straw crushing processing, need to use a kind of mechanical equipment "straw crusher", this kind of crusher is a professional crushing and processing of straw machinery and equipment, can help farmers to bring more economic income.
Hope it can help you, please give a "good review".

Wheat straw is an efficient and long-term raw material for light industry, textiles and building materials, which can not only partially replace bricks, wood and other materials, but also effectively protect cultivated land and forest resources. Straw wall panels are highly insulated, decorative and durable, and many developed countries have widely used "straw boards" as a substitute for wood panels and tiles in the construction industry.
In addition, the processing of straw by technical methods can also be used to make rayon and rayon, to produce furfural, caramel, wine and xylitol, to process fiberboard, and so on.
Combustion hazards. Many large cities prohibit straw burning because the gases produced by burning straw are extremely harmful to the atmosphere.
1. Increase the content of CO2 in the air, and the proportion of CO2 is much greater than that of burning ordinary trees.
2. Increase the inhalable particulate matter in the air, which is a white powdery solid.
3. Reduce the visibility of the air, and generate a large amount of white solid smoke when the straw is burned. Because the solids are very small, they are scattered in the form of powder, which greatly affects the visibility of cities, highways, airports, etc.

(1) The crude fiber content is very high, and the straw is mostly in the post-mature stage of plants, and the degree of lignification of plant cells is very high, generally between 31 and 45.
The main component of straw is fiber (table), which is mainly concentrated in the cell wall, and the cell wall content accounts for more than 70%, which is composed of cellulose, hemicellulose and lignin. Acid detergent fibers are made up of cellulose and lignin. Cellulose and hemicellulose can be acidolyzed by fibrolytic bacteria in the rumen of cattle and sheep to generate volatile fatty acids, such as acetic acid, propionic acid, butyric acid, etc., which are absorbed by cattle and sheep as energy utilization. The bacteria in the rumen cannot break down lignin.
The cellulose, hemicellulose and lignin in the straw are tightly combined, which affects the digestibility of the straw. The older the straw matures, the higher the degree of lignification, and the worse the digestibility of the straw.
The organic digestibility of this kind of substance is low, and the general cattle and sheep rarely exceed 50, and the feed digestion can be between.
-
Wheat straw dry matter 95%, crude protein, crude fat, crude fiber, nitrogen-free extract, ash. After straw ammoniation treatment, the crude protein increased from 3 4 to about 8, the digestibility of organic matter increased by 10 20 percentage points, and contained a variety of amino acids, which could replace 30 40 concentrate feed. It can also kill weed seeds and prevent mildew.
Therefore, ammoniated straw is fed to sheep, cattle, etc., and the effect is very good.

1. The nutritional content of asparagus.
Asparagus is homologous to food and medicine, and the edible part of the ingredients is 90%. Each l00g contains 75 kJ of energy, 93 g of water, protein and fat, dietary fiber, 3g of carbohydrates, 100 g of carotene, 17 g of retinol equivalent, thiamine riboflavin, niacin; Sustaining C 45mg; Potassium 213mg, sodium calcium 10mg, magnesium 10mg, iron, manganese zinc 1mg, copper phosphorus 42mg, selenium. The stems and leaves also contain rutin, quercetin and other substances that protect the elasticity of blood vessels.
Its nutritional characteristics are as follows:
1. Asparagus is low in sugar, low in fat, high in fiber and high in vitamins. Young asparagus stems contain very little water, protein, fat and only crude fiber. The vitamin content is very high, with an average vitamin C content of 100 grams, which is 5 times higher than that of garlic sprouts; Vitamin B1 is 80 mcg per 100 g; Vitamin A is twice that of carrots, reaching 29,400 IU.
2. It is the amino acid composition of protein. The amino acid content is high and the ratio is appropriate. Especially among all amino acids, aspartic acid content is high, accounting for the total content of amino acids, which has a great effect on cardiovascular diseases and urological diseases.
3. Asparagus contains a variety of essential macroelements and trace elements. The content of large elements such as calcium, phosphorus, potassium and iron is very high; Trace elements such as zinc, copper, manganese, selenium, chromium and other components, complete and appropriate, these elements play an important role in the prevention and treatment of cancer and heart disease, nutritionists and vegetarians are considered to be a healthy food and a comprehensive anti-cancer food.
Second, the nutrients of straw.
Straw is a general term for the stem, leaf (spike) part of a mature crop. Usually refers to the residue of wheat, rice, maize, potatoes, rape, cotton, sugarcane and other crops (usually coarse grains) after harvesting the seeds. More than half of the products of crop photosynthesis exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc., and is a renewable biological resource with multiple uses, and straw is also a kind of roughage.
It is characterized by a high crude fiber content (30%-40%) and contains lignin, etc. Although lignin cellulose cannot be used by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock.
The above information to the Internet, I hope it will be helpful to you.

1. After wheat straw bleaching and toughening treatment, it can be used to weave straw hats, straw mounds and various handicrafts. 2. The wood-based panels produced from wheat straw are light in weight, high in strength and have good performance in heat preservation. 3. Wheat straw can be used as a medicinal material.
4. Wheat straw can be used as feed for livestock. 5. Wheat straw can also be used as fuel. Wheat straw refers to the straw of the crop wheat after it has been threshed after maturity.
Benefits of wheat straw: 1. Increase the content of nutrients in the soil: wheat straw contains nitrogen, phosphorus, potassium, calcium, magnesium and other nutrients, and also contains organic matter.
2. Improve soil activity: The energy source of microbial activity in the soil is mainly chemical energy, and it happens that wheat straw contains a large amount of chemical energy, which has the effect of strengthening respiration, fiber decomposition, ammoniation and nitrification.
3. Improve soil physical properties: After the straw is returned to the field, it will be bonded with calcium and magnesium in the soil to form calcium humate and magnesium humate, which can enhance the permeability of the soil, strengthen the ability to retain water and fertilizer, and then promote the root growth of subsequent crops and lay the foundation for improving yield.

After the scientific use of straw, from inefficient combustion to efficient utilization of BAI straw direct combustion power generation, straw biogas, straw solidification, straw distillation, etc., it can not only improve the efficiency of DAO combustion, but also reduce environmental pressure, which is worthy of a good thing for the benefit of the country and the people.
Secondly, straw is rich in organic matter, nitrogen, phosphorus, potassium and trace elements, which is a multi-purpose and renewable biological resource, and is also an important source of organic fertilizer for agricultural production. It is estimated that 700 million tons of straw contain 3.5 million tons of nitrogen, 800,000 tons of phosphorus and 8 million tons of potassium, which is equivalent to about 15 of the total amount of chemical fertilizer application in the country in 2010. Straw is also rich in nutrients, the nutritional value of 4 tons of straw is equivalent to 1 ton of grain, used as feed, can provide material guarantee for the sustainable development of animal husbandry.
In other words, using straw as feed for animal husbandry can save thousands of tons of grain every year.
In addition, straw fiber is a natural cellulose fiber with good biodegradability, which can replace wood and be used for papermaking. In addition, it can also be used for the production of boards, handicrafts, activated carbon, etc., which can save a lot of wood and protect valuable forest resources. After straw entered the industrial field, the application of straw wood-based panels, straw wood plastics, etc. has developed very rapidly, and industrialized production has been realized, and some products have already shown a new look in the Olympic Park, Olympic Village, and World Expo.

Wheat straw can be used to make handicrafts, corn can be fed to cattle and sheep and other livestock, and the straw can be returned to the field as fertilizer after crushing.
Straw can be made not only into thermal insulation foam in refrigerators, roof tiles on houses, craft packaging bags, etc., but also tableware often used in daily life such as plates and cups. "Rice husks, straw, wheat stalks, corn stalks, etc. can be made into tableware, and they will not be damaged after three or four years of normal use. According to the person in charge of the green state new material in Changfeng County, Anhui Province, the daily utensils made of straw are safe and environmentally friendly, antibacterial and antibacterial, and not mildew, and are widely sold in the European and American markets. >>>More
The valency of nitrogen is 0
Valency is the property of an element when one atom of an element is combined with the atoms of another element. In general, the valence of valency is equal to the number of electrons gained and lost by each atom during compounding, that is, the number of electrons gained and lost when the element can reach a stable structure, which is often determined by the electronic configuration of the element, mainly the outermost electron configuration, and of course may also involve the substable structure composed of sublayers that the subouter shell can achieve. Valency indicates the number of electrons gained and lost by atoms when they are combined with each other. >>>More
