What are the benefits of crop straw carbonization?
Recycling of waste corn straw refers to the stems left after harvesting crops, such as wheat, corn, rice, beans, potatoes, melons and other crop straws, which has a wide range of uses. In traditional agricultural production, straw is often burned as plant ash and used as potassium fertilizer, or it is spread in livestock and poultry sheds and mixed with livestock and poultry manure to make farmyard manure, or it is also directly used as compost. Straw charcoal is a kind of biomass charcoal prepared from straw as raw material. It can be widely used in agriculture, environmental protection and other fields.
What are the benefits of straw carbonization?
1) Straw charcoal can be used as carbon-based fertilizer after deep processing after carbonization, increasing the content of carbon-based organic matter in the soil, quickly transforming the soil structure, balancing salt and moisture, creating a soil environment conducive to healthy plant growth through rapid maturation, and increasing Soil fertility, promotes crop growth.
2) In Northeast China, after three consecutive applications of carbon-based fertilizer on degraded black soil, soil organic matter increased by 3g/kg and corn yield increased by more than 15%; in Xinjiang, China, saline-alkali soil was effectively alleviated after the use of carbon-based organic fertilizer. The organic matter is increased by 4g/kg, and the yield per mu is increased by 10.5%.
3) There are by-products after straw carbonization, which can be processed into wood vinegar and wood tar. After reprocessing wood tar, creosote, antipolymerization agent, flotation foaming agent, wood pitch and other products can be obtained. It can also be used in the pharmaceutical, synthetic rubber and metallurgical sectors. Wood vinegar liquid can be used as soil improvement, beverage additive, deodorization and sterilization, feed additive, food preservation, etc.
The continuous straw carbonization furnace can completely turn these straws into treasures and make full use of a large amount of discarded straws. Let the majority of farmer friends no longer worry!
