Fulvic acid biomass functional fertilizer for graminaceous crops, and application thereof

Abstract

The invention discloses a fulvic acid biomass functional fertilizer for graminaceous crops, and an application thereof. The fertilizer comprises 10-40 parts of biomass ash, 3-20 parts of ammonium lignosulfonate, 5-20 parts of sulfonated pine needles, 10-50 parts of urea, 10-20 parts of diammonium phosphate, 10-20 parts of potassium chloride, 3-15 parts of ammonium sulfate, 10-25 parts of ammoniumchloride, 5-15 parts of attapulgite, 1-5 parts of manganese sulfate, 1-5 parts of borax, 1-5 parts of zinc sulfate, 0.5-5 kg / ton of potassium polyaspartate and 5-100 g / ton of compound sodium nitrophenolate. The decomposition problem of an ammonium nitrogen fertilizer meeting the biomass ash is solved, the high-nitrogen compound fertilizer produced from the biomass ash can meet the demand for nitrogen, phosphorus and potassium of the graminaceous crops and can provide a lot of medium trace elements in the biomass ash for plants to absorb and utilize, so the physical and chemical properties of soil are improved, and the comprehensive utilization of the biomass ash is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a fulvic acid biomass functional fertilizer for gramineous crops and an application thereof. Background technique [0002] my country is a large agricultural country. Poaceae plants mainly include wheat, rice, corn and other crops, which are the staple food of our country. The traditional method of fertilization (more than 90 parts) is to apply a large amount of nitrogen, phosphorus, and potassium inorganic fertilizers, and the soil is overloaded, and the medium and trace elements cannot be replenished in time, resulting in the formation of cultivated land, soil acidification, and excessive heavy metals in the active state, which seriously threaten the human body. At the same time, the imbalance of medium and trace elements causes the yield reduction of gramineous crops, which seriously threatens the sustainable development of my country's agriculture....

Problems solved by technology

Patent 201410034726.7 adds tea meal to organic fertilizer without adding biomass ash and ammonium lignin sulfonate; patents CN 105820012 A, CN 105820013 A and CN 105777444 A only add 1-2 parts of biomass ash, which is beneficial to fertilizer The pH has a great influence, and without the addition of ammonium lignosulfonate, it is impossible to complex / chelate with the medium and trace elements in the biomass ash, and the utilization rate of fertilizer nitrogen, phosphorus and potassium is low. low saving capacity

The main components of conventional fertilizers are the three elements of nitrogen, phosphorus and potassium (single element or two of them), which have low utilization rate and do not contain medium and trace elements, so it is impossible to achieve balanced fertilization

Long-term extensive use of inorganic fertilizers leads to nutrient imbalance, arable land consolidation, soil acidification and increased activity of heavy metals, threatening food security and the sustainable development of agriculture

Conventional biomass ash is currently disposed of by landfill or leased land, causing serious pollution to the surrounding air, soil, and water, and causing about 480,000 tons of K 2 O, 640,000 tons of active SiO 2 , 200,000 tons of ZnO and 66,000 tons of B 2 o 3 massive waste of precious resources
