Carbon-containing organic fertilizer suitable for tomatoes and production process

Abstract

The invention discloses a carbon-containing organic fertilizer suitable for tomatoes and a production process, and relates to the field of fertilizers. The production process comprises the following steps: a, selecting raw materials: selecting charcoal as a main material of the carbon-containing organic fertilizer, and controlling the water content of the charcoal to be below 5%; b, proportioningthe raw materials: wherein the carbon-containing organic fertilizer suitable for tomatoes is prepared from the following raw materials in parts by weight: 15 to 30 parts of biochar, 20 to 35 parts ofplant ash, 20 to 45 parts of humic acid and 15 to 25 parts of decomposed cow dung; c, selecting a preparation site: selecting a dry and closed workshop as the preparation site; and d, preparing a mixture, namely crushing the raw materials into 80 meshes, uniformly mixing in proportion, and granulating the mixture. The carbon-containing organic fertilizer suitable for planting tomatoes is developedby utilizing the soil improvement effect of the biochar and combining factors required by organic matters and nutrient elements in the growth process of the tomatoes.

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 tomatoes 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...

However, no matter what crops are planted, the ultimate goal is to increase economic income. Therefore, it is very important whether tomatoes can have a high yield and a good harvest. Tomatoes are also deep-rooted crops with relatively developed root systems and wide and deep distribution. The soil absorbs a lot of nutrients, but no matter whether it is cultivated in open field or protected area, it is often deficient in phosphorus and potassium due to improper fertilization time, which leads to symptoms such as plant weakness and deformed results, resulting in low yield, poor quality and poor benefit
