Embodiment 2

[0020] While using lignin or lignin derivatives to solve the problem that plant ash is easy to form fly ash and dust, a new method is provided by oxidizing and degrading lignin with dilute nitric acid, and then neutralizing it with alkaline plant ash (mainly alkaline The substance is potassium carbonate) instead of the traditional neutralization method with ammonia water, which can simplify the production process and reduce the production cost (ammonia water is highly volatile, making the production operation complicated), and produces o-quinone plant growth hormones. In addition, by adding an excessive amount of hay ash, the generated o-quinone auxin can be adsorbed, dispersed and diluted in plant ash or in the mixed powder of plant ash and acidified lignin, so as to achieve the purpose of convenient application and obtain the desired plant growth hormone. The purpose of compound fertilizer, the ratio of its components in each phase is required to be determined according to th...

Embodiment 3

[0023] In order to further improve the performance of the compound fertilizer, a certain proportion of ammonium oxidized lignin nitrogen fertilizer or nitrified lignin chelated fertilizer or superphosphate or their mixture is added to the organic-inorganic compound fertilizer obtained by mixing the above-mentioned lignin and plant ash. Part of the lignin is subjected to ammonification or nitrification treatment to obtain ammonia oxidized lignin nitrogen fertilizer, which also has a similar effect to the indole ring plant hormone. It is known that kraft lignin can increase nitrogen content through ammonification oxidation reaction, and has a controlled release effect on N. Using papermaking black liquor lignin as raw material, according to a certain liquid ratio, dissolving lignin in dilute ammonia water, adding a composite catalyst, and undergoing ammonification and oxidation reactions at a certain temperature and oxygen pressure to obtain a nitrogen content of 15.47%. ammonia...

Abstract

The present invention relates to a compound fertilizer containing plant ash and a production method thereof, and in particular to a low-cost industrial large-scale production method. Through uniform mixing and stirring of acidified lignin and plant ash, the ash-shape plant ash agglomerates or forms into particles, so as to solve problems of flying dust and strong basicity of the plant ash, as well as obtain an effective organic and inorganic compound fertilizer.

Description

technical field [0001] The invention relates to a compound fertilizer containing plant ash and a production method thereof. Background technique [0002] It is known that plants first absorb a large amount of nutrients such as carbon, hydrogen, oxygen, nitrogen, potassium, calcium, magnesium, phosphorus, and sulfur from the air, soil, and water. Micronutrients such as chlorine, iron, manganese, boron, zinc, copper, and molybdenum must then be absorbed from the soil. Without any one of these sixteen nutritional elements, higher plants cannot grow normally, so they are called essential nutrients for the growth of higher plants. Ash fertilizer can be divided into grass ash, wood ash and plant ash fertilizer. It contains phosphorus pentoxide, potassium oxide and other nutrients as follows: grass ash: 2.11%-2.36%, 8.09%-10.2%; wood ash: 3.1%-3.41%, 5.92%-12.4%; plant ash: 3.5%, 7.5% . In addition, plant ash also contains more than 0.9% calcium oxide. In addition, silicon is ...
