Carbon-containing organic fertilizer suitable for pears and production process

Abstract

The invention discloses a carbon-containing organic fertilizer suitable for pears and a production process, and relates to the field of fertilizers. The production process comprises the following steps: a, selection of raw materials: selecting biochar as a main material of the carbon-containing organic fertilizer, and controlling the water content of the biochar to be below 5%; b, proportioning ofthe raw materials: preparing following raw materials of the carbon-containing organic fertilizer in parts by weight: 20 to 45 parts of decomposed cow dung, 15 to 25 parts of charcoal, 10 to 20 partsof plant ash and 10 to 20 parts of decomposed edible fungus waste; c, selecting a preparation site: selecting a dry and closed production workshop as the preparation site; and d, preparing a mixture:crushing the raw materials into 80 meshes, uniformly mixing the components in proportion, and granulating the mixture. The carbon-containing organic fertilizer suitable for planting pears is developedby utilizing the soil improvement effect of biochar and combining factors required by organic matters and nutrient elements in the growth process of the pears.

Description

technical field [0001] The invention relates to the technical field of production and processing of carbon-containing organic fertilizers, in particular to a carbon-containing organic fertilizer suitable for pears and a production process. Background technique [0002] The annual output of quick-acting chemical fertilizers in my country ranks first in the world, and the annual use of quick-acting chemical fertilizers has reached more than 51 million tons (scale), accounting for more than 30% of the world's total consumption, which is the sum of the United States and India. The average amount of chemical fertilizer used per mu of crops in my country is 21.2 kg, far higher than the world average of 8 kg, three times that of the United States, and 2.5 times that of India and the European Union. my country has become the world's largest consumer of chemical fertilizers. Excessive use of chemical fertilizers not only increases the cost of agricultural planting, but also causes so...

Problems solved by technology

However, in some areas, the content of soil organic matter is low, and the lack of trace elements such as calcium, iron, zinc, and boron is common. Especially in the pear orchards in the south, the soil is deficient in phosphorus, potassium, calcium, and magnesium, and the soil acidification is serious, which limits the production of pears.
