Problems solved by technology

[0006] However, for a long time, due to the unscientific formula of large, medium and micronutrient elements in cassava fertilization management, it often leads to the decline of cassava yield, quality, postharvest storability, and the intensification of diseases and insect pests.
In addition, since cassava harvests are mainly tubers, the tubers have to go through a long period of formation and expansion during the growth process, and the soil texture is too sticky or compacted, which also seriously affects the growth and yield of tubers.

Abstract

The invention discloses a carbon-based fertilizer special for cassava. The carbon-based fertilizer is prepared from the following raw materials in parts by weight: 200 to 250 parts of nituminous urea,350 to 450 parts of magnesium ammonium phosphate, 300 to 400 parts of potassium nitrate, 6 to 12 parts of calcium sulfate, 15 to 25 parts of charcoal, 0.5 to 1.4 part of zinc chloride, 0.5 to 1.4 parts of boronic acid, 0.5 to 1.4 parts of manganese sulfate, 0.5 to 1.4 parts of ferric sulfate. By adopting the carbon-based fertilizer special for the cassava and the preparation method thereof, the prepared fertilizer has full nutrients, and is durable and persistent in supplying; topdressing is not required after fertilizing at a time, environment-friendliness and a function of improving obstacle soil are achieved; the quality and yield of the cassava can be increased and improved remarkably, so that the prepared fertilizer has the advantages of saving in labor force and time, remarkable economical benefit and ecological benefit and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special carbon-based formula fertilizer for cassava and a preparation method thereof. Background technique [0002] Energy is the material basis for the survival of human beings. The limitations of fossil energy such as coal, oil, and natural gas, and the enormous pressure on the environment and ecology caused by the development and utilization process have seriously restricted the sustainable development of the economy and society. The development and utilization of clean and renewable Energy has become an urgent issue facing the energy field in the world today. [0003] Biomass energy is the energy form of solar energy stored in biomass in the form of chemical energy. It uses biomass as a carrier, directly or indirectly derived from the photosynthesis of green plants, and can be converted into conventional solid, liquid and gaseous fuels, replacing Fossil fu...
