Biomass charcoal-based compound fertilizer special for wheat and preparation method of biomass charcoal-based compound fertilizer

Abstract

The invention discloses a biomass charcoal-based compound fertilizer for wheat. The biomass charcoal-based compound fertilizer comprises the following components in parts by weight: 8 to 14 parts of potash magnesium sulphate fertilizer, 12 to 17 parts of potassium chloride, 6 to 13 parts of fertilizer-level calcium hydrophosphate, 13 to 21 parts of urea phosphate, 30 to 40 parts of powdery urea, 8 to 14 parts of soybean straw powdered carbon, 2 to 7 parts of sodium silicate, 1 to 4 parts of EDTA chelate Zn, 1 to 4 parts of EDTA chelate Fe, 1 to 5 parts of ammonium molybdate and 3 to 7 parts of an auxiliary material. The invention further discloses a preparation method for the biomass charcoal-based compound fertilizer special for the wheat. According to the invention, after the biomass charcoal-based compound fertilizer special for the wheat is applied, not only can soil be effectively improved and fertilized, the content of soil organic matter can be increased, the volume weight of soil can be reduced, and the water retention and fertilizer retention capabilities of the soil can be improved, but also the fertilizer nutrient utilization efficiency is relatively high, nutrient element release is coordinated and lasting, nutrient can be supplied to the wheat relatively comprehensively and evenly, the output of the wheat can be obviously improved, the quality of the wheat can be improved, and obvious economic benefit can be achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special biomass charcoal-based compound fertilizer for wheat and a preparation method thereof. Background technique [0002] China's current arable land area is 1.831 billion mu. Due to the development of urban and rural economies, more arable land will be occupied. According to the forecast of relevant departments, China's population will increase to about 1.5 billion in the future, with more people and less land plus fresh water The problem of insufficient resources will become a long-term factor affecting the security of China's food supply and demand. Wheat is the main food crop in my country. The improvement of wheat quality and yield has attracted more and more attention. The use of agricultural chemical fertilizers occupies an important role in my country's wheat production. Due to some unreasonable factors in the use process, not only the nutrient utiliza...

Problems solved by technology

The current chemical fertilizer market is mainly based on fully soluble, instant, and quick-dispersing chemical fertilizers, which intensifies the waste of fertilizers and the loss of nutrients. In production, it is necessary to use multiple topdressing fertilizers to meet the nutrient needs of crops throughout the growth period. Not only is it labor-intensive and increases the cost of fertilization, but also the nutrient loss of topdressing and surface application of fertilizers is large, which obviously reduces the fertilizer efficiency and makes it difficult to exert the production-increasing effect of fertilizers
