Organic slowly-released horticultural ecologic nutrient soil and preparation method thereof

Abstract

The invention discloses organic slowly-released horticultural ecologic nutrient soil and a preparation method thereof. The nutrient soil is prepared from, by weight, 20-30 parts of composite filling soil, 6-10 parts of modified biological carbon, 1-2 parts of trace element additive, 0.1-0.3 part of growth regulator, 30-50 parts of fermented humus, 8-10 parts of filling ash, 3-5 parts of tobacco scrap, 6-8 parts of loosening and water retention fibers and 8-12 parts of water. The nutrient soil is abundant in nutrient, great in plant absorptivity, long in fertilizer efficiency time, capable of promoting rooting and sprouting of nursery stocks and suppressing generation of soil germs and excellent in air permeability and drainage performance. By adopting a great number of agricultural and industrial scraps, the resource is saved, and the ecological environment is protected. According to the preparation method, raw materials are easy to obtain, the process is simple, and the method has a high practical value and a great application prospect.

Description

technical field [0001] The invention relates to the technical field of seedling planting, in particular to an organic slow-release horticultural ecological nutrient soil and a preparation method thereof. Background technique [0002] Nutrient soil is specially formulated to meet the growth and development of seedlings, containing a variety of mineral nutrients, loose and ventilated, and [0003] The bed soil with strong water and fertilizer retention ability and no pests and diseases. Nutritionally, it is generally prepared by mixing fertile field soil and decomposed manure. [0004] Plant nutrient soil is often prepared by adding nutrient solutions such as vermiculite, sand, and expanded stones. However, plant growth requires not only nutrition, but also the following requirements for nutrient soil: strong air permeability, water retention capacity, suitable for root growth, Antibacterial and antibacterial, promote roots and seedlings, activate nutrients, and prevent vari...

Problems solved by technology

[0005] On the other hand, the existing flower nutrient soil has a series of defects when used: the fermentation and decomposing process with straw as the main organic material undoubtedly greatly increases the cost and production cycle; the nutrient soil prepared after the organic material is fermented and decomposed inevitably has rancidity smell and musty warehouse smell, especially the nutrient soil added with livestock and poultry manure, it is not suitable for gardening soil for beautifying the environment

[0006] In addition, most of the common nutritious soils on the market are prepared from pastoral soil, humus soil, and chemical fertilizers. However, these nutritious soils mainly use chemical fertilizers and pastoral soil. After a period of use, the soil is easy to harden and the air permeability becomes poor. , may cause damage to some plants that require high air permeability of the root system, and the soil is basically not sterilized, which may adversely affect the growth of some seedlings with weak resistance, and at the same time make the seedlings in the cuttings vulnerable to pests and diseases , low survival rate, underdeveloped root system after cuttings survived, poor seedbed fertility, and slow growth
