Abstract

The invention belongs to the field of crop fertilizer, and more specifically relates to a fruit special fertilizer synergist, and a preparation method thereof. The fruit special fertilizer synergist is mainly composed of following raw materials, by weight, 10 to 40 parts of apple residue, 20 to 40 parts of orange peel, 5 to 15 parts of a modifier, 5 to 10 parts of guar gum, 10 to 20 parts of an oxidized lignosulfonate, 10 to 30 parts of biomass charcoal, and 1 to 10 parts of trace elements. The fruit special fertilizer synergist contains relatively more active groups, and possesses relatively high adsorption capability; complexation with nutrient compositions in the soil is easily caused, and complexation capacity with potassium is especially excellent; loss of fertilizer nutrients can be prevented; absorption and utilization of crops on trace elements are promoted; and fertilizer utilization ratio is increased. According to the preparation method, forestry and agricultural residues are taken as the main raw materials; the fruit special fertilizer synergist is a biomass synergist; the raw materials are widely available; production cost is low; and no environmental pollution is caused.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, and in particular relates to a special fruit fertilizer synergist and a preparation method thereof. Background technique [0002] my country is a country with a large agricultural development. The small area of ​​arable land and low grain output are the biggest problems facing my country's agricultural development. At present, the important means to increase grain output is the application of chemical fertilizers. my country is the largest producer and user of chemical fertilizers in the world. The annual amount of chemical fertilizer application accounts for 35% of the world's total, but the utilization rate of chemical fertilizers is less than 30%, which is far lower than that of developed countries. Due to the low utilization rate of chemical fertilizers, in order to pursue high grain yields, farmers use a large amount of chemical fertilizers, which not only increases the economic burden, but a...
