Special compound fertilizer for gardens

Abstract

The invention relates to special compound fertilizer for gardens. The special compound fertilizer for the gardens is characterized by being prepared from components in parts by weight as follows: 20-30 parts of volcanic ash, 20-30 parts of plant ash, 20-30 parts of leaf mold, 10-15 parts of pine needle soil, 5-10 parts of perlite powder, 3-5 parts of urea, 1-2 parts of pyranyl benzyladenine, 0.5-1part of butyrin, 1-2 parts of humic acid, 0.5-1 part of calcium superphosphate, 0.5-1 part of lignin organic matter, 1-2 parts of carboxymethyl chitosan, 0.5-1 part of a water retaining agent and 0.5-1 part of microbial nitrogen-fixing bacteria. The compound fertilizer also has the characteristics of stable, long and complete fertilizer efficiency, can improve soil properties, fertilize soil, reduce effects of soil-borne diseases and save the labor cost, can be widely applied to base fertilizer and topdressing of various garden greening seedlings and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of garden fertilizers, in particular to a special compound fertilizer for gardens. Background technique [0002] Seedlings are saplings with roots and stems. All saplings cultivated in the nursery, regardless of their age, are called seedlings before they come out of the nursery. The types of seedlings include seedlings, vegetative propagation seedlings, transplanted seedlings, and bed seedlings. The seedlings cultivated in the nursery may take several years at least, and some species such as flowering shrubs may take more than ten years or even decades. During the cultivation of seedlings, regular fertilization is required. The fertilizers involved include organic fertilizers and inorganic fertilizers. Organic fertilizers are also called farmyard manures, including human excrement, compost peat, etc. There are many types, wide sources, Complete nutrients, inorganic fertilizers are also called chemical fert...
