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 amount of nutrient loss in topdressing and surface application of fertilizers is large, which obviously reduces the fertilizer efficiency and makes it difficult to increase the production of fertilizers. How to prepare a fertilizer that can not only improve soil properties, increase soil fertility, rich in nutrients, and nutrients Coordinated and long-lasting release, high fertilizer nutrient utilization efficiency, one-time fertilization without topdressing or less topdressing corn fertilizer has become a technical problem that needs to be solved at present

Abstract

The invention discloses a special biomass charcoal-based composite fertilizer for corn. The special biomass charcoal-based composite fertilizer for the corn comprises the following components in parts by weight: 7-15 parts of potassium magnesium sulfate fertilizer, 3-7 parts of potassium chloride, 5-13 parts of fertilizer-grade calcium hydrogen phosphate, 15-20 parts of urea phosphate, 40-50 parts of powdery urea, 6-9 parts of rapeseed straw charcoal powder, 0.2-0.8 part of sodium silicate, 0.05-0.47 part of EDTA (ethylenediaminetetraacetic acid) chelated zinc, 0.05-1 part of EDTA chelated manganese and 1-7 parts of auxiliary materials. The invention further discloses a preparation method of the special biomass charcoal-based composite fertilizer for the corn. After the special biomass charcoal-based composite fertilizer for the corn, disclosed by the invention, is applied, the soil can be effectively improved and fertilized, the content of organic matters in the soil is increased, the soil bulk density is reduced, and the water-retaining and fertilizer-keeping capability of the soil is improved; furthermore, the utilization efficiency of fertilizer nutrients is relatively high, the release of nutrient elements is coordinated and lasting, the nutrients can be supplied to the corn in a relatively comprehensive and balanced manner, the yield of the corn is significantly improved, the quality of the corn is improved, and the economic benefits are obvious.

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 corn and a preparation method thereof. Background technique [0002] Corn is China's largest food crop and an important source of feed, and it is also the food crop with the highest total output in the world. Corn contains a large amount of isomaltooligosaccharides, which is the best among prebiotics. Prebiotics are probiotics. Food is closely related to the reproduction of probiotics in the human body, so as to achieve a balanced state of intestinal flora and make the intestinal tract healthy. The metabolizable energy of corn is 14.06MJ / kg, and the highest can reach 15.06MJ / kg, which is the highest among cereal feeds. Corn also contains a lot of magnesium, which can strengthen the peristalsis of the intestinal wall and promote the excretion of waste from the body. [0003] At present, the improvement of c...
