Special fertilizer for Chinese torreya seedling base fertilizer and preparation method thereof

Abstract

The invention discloses a special fertilizer for a Chinese torreya seedling base fertilizer and a preparation method thereof. The special fertilizer is prepared from the following raw materials in parts by weight: 80-100 parts of chicken manure, 8-10 parts of bamboo shoot shells, 12-16 parts of rice hulls, 4-8 parts of carya cathayensis sarg peels, 8-12 parts of zeolite powder, 0.2-0.5 part of zinc sulphate, 4-7 parts of potassium feldspar, 0.5-0.8 part of polyglutamic acid, 0.1-0.3 part of a decomposition agent, 0.05-0.2 part of bacillus mucilaginosus, 0.1-0.3 part of trichoderma harzianum and 0.5-1 part of polyvinyl alcohol. The special fertilizer provided by the invention is capable of promoting the growth of Chinese torreya seedlings, slowly and effectively releasing fertilizer ingredients, reducing a fertilization frequency, and reducing a production cost; the special fertilizer further has the function of resisting drought and flood, is capable of preventing the root rot of the Chinese torreya seedlings, and is pollution-free to people and livestock, and the surrounding environment; the special fertilizer provided by the invention is simple in process, convenient to produce, capable of improving soil environment, and beneficial to the health growth of the Chinese torreya seedlings.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and relates to an agricultural fertilizer, in particular to a special fertilizer for the base fertilizer of Chinese torreya seedlings and a preparation method of the special fertilizer. Background technique [0002] Torreya is distributed in the south of the Yangtze River in my country. It belongs to the evergreen plant of the Taxaceae Torreya genus. Its fruit is a high-grade nut unique to my country. Torreya torreya has a long growth cycle, the seedlings grow slowly, and the success rate is low. The root of Chinese torreya is a fleshy root, which responds strongly to fertilizer components. Choosing organic fertilizers with long-lasting fertilizer effects is more conducive to the growth of Chinese torreya plants. Torreya seedlings grow well in deep, fertile, loose, well-drained soil. Reasonable fertilization is an important guarantee for the rapid growth of Torreya seedlings. [0003] A...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the torreya seedlings are applied with nitrogen, phosphorus and potassium compound fertilizers, which are mainly composed of three inorganic elements N, P, and K. From the nutritional composition, they can meet the growth needs of torreya seedlings, but long-term use will damage the soil aggregate structure. damage, it is easy to cause soil compaction and soil hardening, thus affecting the growth of seedlings, and has high requirements for fertilization management, and a little carelessness will result in low survival rate of seedlings

[0004] At present, there is no special fertilizer designed for Torreya seedlings on the market, and blind fertilization in production has caused an imbalance in the ratio of nitrogen, phosphorus, and potassium in the soil of Torreya forest.
