Both practical alkalization and ammoniation methods have their advantages and disadvantages. How can they better play and enhance their effective role in solving and overcoming their shortcomings? There is currently the best and newest way to solve this problem - composite chemical processing. The straw treated by the composite chemical method has the advantages of low cost, easy preservation, and improved straw digestion and utilization efficiency. According to the experiment, straw treated with 2% urea plus 3% calcium hydroxide (lime plus water) can achieve or exceed the effect of 4% urea ammoniation or 5% alkaline calcium hydroxide alone. . The basic operation of composite chemical treatment is the same as that of urea ammoniated straw. The only difference is that the treatment agent is urea plus calcium hydroxide (hydrated by lime). Dosage: Add 3 kg urea and 3 kg of quick lime per 100 kg of water to make a composite treatment solution, and then spray 100 kg of straw with 30 kg of the above composite treatment solution, and then pack and seal.

Straw modulation technology
In winter and spring, farmers raising cows have to increase the nutritional value of straw feed (straw, corn stover, etc.), and some of them are alkalized and some are ammoniated. The processing of the prepared straw with lime alkali treatment can break the connection between cellulose and lignin, which is beneficial to the function of microorganisms in the rumen of the cattle and increase the digestibility of the straw. However, the straw treated by the alkalization method is not easy to preserve and is easy to mold and metamorphose. The straw prepared by urea ammoniating method can cause aminolysis reaction between organic matter and ammonia, destroy fiber structure, increase digestibility, and increase nitrogen content of straw, but the cost of using urea ammoniation is high and some ammonia nitrogen is lost. At the same time, the effect of the ammoniated treatment is not as good as the alkalizing effect.
