Multifunctional compound fertilizer for cultivating nursery-grown plant and preparation method thereof

Abstract

The invention discloses multifunctional compound fertilizer for cultivating a nursery-grown plant. The multifunctional compound fertilizer is prepared from the following raw materials in parts by weight: 10 to 20 parts of power-plant ash, 15 to 25 parts of livestock excrement, 0.8 to 1.2 parts of pyroxasulfone, 1 to 1.6 parts of fenclorim, 10 to 16 parts of dispersant, 20 to 30 parts of slow release additive, 0.1 to 1 part of malathion, 4 to 8 parts of rapeseed cake, 8 to 14 parts of plant ash, 1 to 2 parts of sulfur powder, 1 to 2 parts of lime powder, 20 to 30 parts of food processing waste, 2 to 4 parts of compound fertilizer and 2 to 3 parts of EM (Effective Microorganism) microbial inoculum. The multifunctional compound fertilizer for cultivating the nursery-grown plant, which is provided by the invention, is made through biological fermentation and the compounding of multiple environment-friendly materials; nutrient elements of the multifunctional compound fertilizer are complete; soil can be effectively ameliorated; the hardening of the soil, which is caused as chemical fertilizer is excessively used is prevented; the vigorous growth of the nursery-grown plant is promoted; in addition, the fertilizer also has deinsectization and weeding functions; further, after the fertilizer is applied once, a nutrient can be slowly released; the utilization rate of the fertilizer is improved; the loss of fertilizer efficiency is decreased; meanwhile, a preparation method provided by the invention is lower in material cost and concise in process; the raw materials are easily obtained; the multifunctional compound fertilizer has higher use value and a favorable application prospect.

Description

technical field [0001] The invention relates to the technical field of seedling fertilizer manufacturing, in particular to a multifunctional compound fertilizer for seedling cultivation and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the attention to the ecological environment is becoming more and more urgent. It is one of the important measures to improve the quality of ecological environment and promote the coordinated development of economy, society and ecological environment by making full use of idle land such as barren hills and slopes, road sides, villages, communities, etc. At the same time, the development of economy, agriculture, and forestry in Shandong Province has an important position in my country. In recent years, the development goal of building a "large horticulture province" has been proposed, which will usher in opportunities for the development of gardens and seedling production in Shando...

Problems solved by technology

Existing technologies (such as the above-mentioned patent documents) apply the three technologies separately. Although the same effect can be achieved, it is relatively wasteful of manpower and material resources and increases production costs.

[0003] On the other hand, the slow and controlled-release fertilizers currently popular in the market mainly use technologies such as urease inhibitors, polypeptide agents, urea-formaldehyde, and coatings. Most of them use chemical raw materials, and some materials are not easy to degrade. Secondary pollution, most of the slow-release technologies are imported from abroad
